You need to borrow somewhere between £1,000 and £5,000, and you are trying to work out whether a personal loan or a credit card is the cheaper way to do it. The answer is not always the same. For small amounts repaid within a few months, a 0% purchase credit card can be genuinely free to use. For larger amounts or longer repayment periods, a personal loan is almost always the cheaper product. The crossover point depends on the specific card terms, the loan APR, and how quickly you repay.
This guide compares the two products across five dimensions: total cost, flexibility, consumer protection, credit file impact, and the behavioural risks that make one product more expensive than the other in practice. It also includes an interactive comparator that models both options side by side at any amount, rate, and monthly payment. All rate figures and worked examples are illustrative and do not represent any specific lender or card provider. This article is for informational purposes and does not constitute financial advice.
At a Glance
-
A 0% credit card can be genuinely cheaper than any loan, but only if the balance is cleared before the promotional rate ends.
During a 0% period, no interest is charged. If you borrow £2,000 on a 0% purchase card and repay it in full within the promotional window, the total cost is £2,000. A personal loan for the same amount would cost more, regardless of the rate. The risk is what happens if the balance is not cleared in time. The revert rate on most credit cards is 20% to 25% APR or higher, and at that point the credit card becomes significantly more expensive than a loan would have been.
-
The minimum payment trap is the single biggest cost risk on a credit card. It can turn a small balance into decades of repayment.
Credit card minimum payments are typically the greatest of 1% of the balance plus that month’s interest, around 2.5% of the balance, or a fixed floor of £5 to £25. Because the payment shrinks as the balance does, £3,000 at 22% APR on minimum payments takes over 28 years to clear and costs more than £5,000 in interest. A personal loan for the same amount over three years costs a fraction of that, and the fixed structure prevents the pattern from arising at all.
-
Credit cards carry Section 75 protection on purchases over £100. Personal loans do not. This is a genuine advantage worth factoring in.
If you buy something with a cash price of more than £100 and not more than £30,000 on a credit card, and the goods are faulty, not delivered, or the seller goes bust, the card provider is jointly liable with the retailer under Section 75 of the Consumer Credit Act. This does not apply to a general-purpose personal loan. For higher-value purchases where the risk of something going wrong is meaningful, it can be the deciding factor even when the card costs more.
The short answer: it depends on three things
The cheapest way to borrow depends on the amount, the repayment timeline, and the discipline of the borrower. There is no single answer that applies to every situation, but the general pattern is consistent enough to be useful as a starting point.
For amounts under £3,000 that can be repaid in full within 12 to 18 months, a 0% purchase credit card is typically the cheapest option, provided the borrower has access to one and can commit to clearing the balance before the promotional period ends. During the 0% window, the borrowing is free. No personal loan, however competitive the rate, can match that.
For amounts above £5,000, or for any amount where repayment will take longer than the available 0% period, a personal loan is almost always cheaper. Personal loan APRs for mainstream borrowers are typically lower than credit card standard rates, and the fixed repayment structure means the debt has a guaranteed end date. The gap in cost widens as the amount increases and the repayment period extends.
The middle ground, roughly £3,000 to £5,000, is where the comparison is closest and where the specific terms of the card and the loan matter most. The comparator below models both options side by side for any amount, APR, and monthly payment, and shows the exact monthly payment at which the two products cost the same.

How to use this tool
The same amount is used for both products so the comparison is like-for-like. The tool shows the typical representative APR band for the amount you choose, because loan pricing varies sharply by size. Small loans are proportionally more expensive. If you have run an eligibility check, enter the rate you were shown.
“Fixed amount” models a standing order at a set level. “Minimum only” models the contractual minimum, which declines as the balance falls. The difference between the two is usually the largest number on the page, and it is the reason credit card costs are so hard to predict.
Set the promotional length and the rate it reverts to. The tool models both phases and tells you the monthly payment that would clear the balance before the revert rate applies. That is the single most useful figure if a 0% card is on the table.
The panel shows total cost and clearance time; the verdict explains which is cheaper and why. The breakeven figure gives the monthly card payment at which the two products cost exactly the same, which is often more useful than either individual result.
When a 0% credit card is genuinely cheaper
A 0% purchase credit card charges no interest on new purchases for a set period, typically between 6 and 24 months depending on the card and the applicant’s credit profile. During this period, the borrower can spread the cost of a purchase over several months without paying any interest at all. If the full balance is cleared before the promotional period ends, the total cost of borrowing is zero. This is the credit card’s strongest advantage, and for the right situation, it is unbeatable.
The scenario where this works well is a planned purchase with a defined cost that the borrower can realistically clear within the promotional window. A £2,000 purchase on a card with an 18-month 0% period requires payments of about £112 per month to clear in full. If the borrower sets up a standing order for that amount and maintains it, the total cost is £2,000. A personal loan for the same amount at an illustrative 9.9% APR over 18 months would cost about £2,160, with £160 going to interest. The credit card saves £160.
The scenario where it goes wrong is when the balance is not cleared before the promotional period ends. At that point, the revert rate kicks in. Most credit card revert rates sit between 20% and 25% APR, and some are higher. If £1,500 of the original balance remains when the 0% period ends, that £1,500 is now accruing interest at the revert rate. At £100 per month it takes a further 18 months to clear and costs about £270 in interest. The 0% period is only an advantage if it is used to clear the balance, not to defer it.

Revert period totals
This example assumes £1,500 remaining when the 0% period ends. The actual remaining balance depends on the payments made during the promotional period. Interest is calculated monthly on the remaining balance. Figures rounded to the nearest pound and match the comparator’s simulation.
One further risk applies to 0% deals specifically. Most promotional offers are conditional on the account being kept in order: if a minimum payment is missed, the provider may withdraw the promotional rate and apply the standard purchase rate to the whole remaining balance. The comparator assumes the promotional rate runs for the full stated period, so a missed payment would push the real cost above what the tool shows. A personal loan’s cost, by contrast, does not change if a payment is missed. Late fees and credit file damage apply, but the rate stays put. The 0% card’s advantage is conditional on payment behaviour in a way the loan’s is not.
When a personal loan costs less
A personal loan becomes the cheaper option in two circumstances: when the amount is too large to clear within a 0% period, and when the borrower does not have access to a competitive 0% card. For amounts above £5,000, both conditions are usually met.
Personal loan APRs for mainstream borrowers are typically well below credit card standard rates, though the gap depends heavily on how much is being borrowed. Loan pricing in the UK is banded, and the bands are steep at the bottom: leading representative rates in mid-2026 ran at roughly 9.9% for loans under £3,000, 9.2% for £3,000 to £4,999, 6.9% for £5,000 to £7,499, and 5.9% for £7,500 and above. Small loans are proportionally expensive because a lender’s administrative costs are largely fixed. A standard credit card purchase rate, meanwhile, is more likely to sit above 20%: Bank of England data put the average UK credit card interest rate at around 24.7% at the end of 2025. The 22% used in the examples below is therefore a favourable card rate rather than a typical one.
The following worked example illustrates the comparison for a £5,000 purchase repaid over three years. All figures are illustrative and do not represent any specific product.
| Factor | Personal loan at 6.9% APR | Credit card at 22% APR |
|---|---|---|
| Monthly payment | £154 (fixed for 36 months) | Varies. Minimum payments decrease as the balance falls, extending the repayment period. |
| Total repaid | Approximately £5,550 | Approximately £7,667 if repaid at a fixed £154/month. Substantially more on minimum payments. |
| Total interest | Approximately £550 | Approximately £2,667 at a fixed £154/month, over 50 months rather than 36. |
| Repayment end date | Fixed at 36 months. The debt is guaranteed to be cleared. | No fixed end date. Depends entirely on how much the borrower pays each month. |
| Risk if circumstances change | Payment is fixed. If income drops, the payment cannot be reduced without contacting the lender. | Payment is flexible. The borrower can reduce to the minimum in a difficult month, but this extends the debt and increases the total cost. |
The total cost difference in this example is approximately £2,117 in favour of the personal loan. Note that the same £154 per month does very different work in each column: on the loan it clears the debt in exactly 36 months, while on the card it takes 50 months, because the first payments are absorbed largely by interest. On minimum payments the difference would be far larger again.

Personal loan: £5,000 at 6.9% APR over 36 months
Credit card: £5,000 at 22% APR, £154/month
The difference
The loan uses the standard annuity formula with monthly compounding. The card is simulated month by month, with interest applied to the outstanding balance before the payment. Both rates are illustrative. Figures rounded to the nearest pound.
For an explanation of how APR works on personal loans and why the advertised rate is not guaranteed to all applicants, the guide to understanding APR on personal loans covers the representative APR system, and the representative APR reality checker shows how far the rate you are offered can differ from the one advertised.
The minimum payment trap
This is the single biggest cost risk on a credit card, and it is the reason a card can end up dramatically more expensive than a personal loan for the same amount. Credit card minimum payments are typically calculated as the greatest of three figures: 1% of the outstanding balance plus that month’s interest and charges, a flat percentage of the balance of around 2.5%, or a fixed floor of £5 to £25. Whichever is largest is what falls due. As the balance falls, the minimum falls with it. The borrower pays less each month, which feels like progress, but the declining payment means the balance is repaid more and more slowly.
The arithmetic is stark. On a £3,000 balance at an illustrative 22% APR, paying only the minimum takes over 28 years to clear. The total interest comes to more than £5,000, well above the original amount borrowed, and the total repaid is over £8,000. The same £3,000 on a personal loan at an illustrative 9% APR over three years costs about £434 in interest, with the debt guaranteed to be cleared in 36 months.
Show the working
£100/month on £3,000 at 22% APR
Minimum payments only on £3,000 at 22% APR
The difference
Minimum payment modelled as the greatest of 1% of balance plus interest, 2.5% of balance, or £5. At 22% APR the first of these is always the largest. Interest is calculated monthly on the outstanding balance. Providers vary in how they set minimums, so your own figures may differ. Rounded to the nearest pound; matches the comparator’s simulation.
A personal loan removes this risk entirely. The monthly payment is fixed at the start and does not change. The debt has a defined end date. There is no option to pay less in a given month without contacting the lender, which removes the temptation to reduce payments when the budget feels tight. For borrowers who know they are likely to default to minimum payments on a credit card, a personal loan is the structurally safer product, regardless of the rate comparison. The loan term vs total cost explorer shows the same trade-off from the other direction: how stretching a fixed term increases the total paid.
What actually happens on a decades-long balance
The 28-year figure above is arithmetically correct, but it describes what would happen if nobody intervened. In the UK, somebody does. Since 2018, FCA rules have required credit card providers to act when a customer is in what the regulator calls persistent debt: paying more in interest, fees and charges than in principal over an 18-month period.
The obligations escalate. At 18 months, the provider must make contact, explain that increasing payments would reduce both the cost and the time, and encourage the customer to get in touch. If the pattern continues, the same communication is repeated. By 36 months, the provider must propose a way of repaying the balance over a reasonable period, which the FCA takes to mean three to four years, and is generally expected to suspend the card while that happens. Where the customer cannot afford the proposed repayments, the provider must show forbearance, which can include reducing, waiving or cancelling interest, fees or charges.
This matters for two reasons. It means the multi-decade scenarios used to illustrate the minimum payment trap are a demonstration of the arithmetic rather than a prediction of what a UK cardholder would actually experience. And it means that if you find yourself in that position, the provider is required to help rather than entitled to let it run. A letter about persistent debt is not a warning to be ignored but the beginning of a process designed to get the balance cleared. None of which makes minimum payments a good idea. It simply means the ceiling on the damage is lower than the raw calculation implies.
Section 75 protection: a genuine credit card advantage
Section 75 of the Consumer Credit Act 1974 provides a powerful form of consumer protection. If you buy something with a cash price of more than £100 and not more than £30,000 using a credit card, and the goods are faulty, not as described, or the seller fails to deliver (including if the seller goes out of business), the credit card provider is jointly and severally liable with the retailer. You can claim against the card company directly, even if the retailer has ceased trading.
This does not apply to a general-purpose personal loan. If you pay for a holiday, a piece of furniture, or a service using funds from a personal loan and the supplier fails to deliver, your claim is against the supplier alone, and the loan repayments continue regardless. One qualification worth knowing: Section 75 can apply to point-of-sale finance, meaning the credit arranged by the retailer at the moment of purchase, as well as to some store cards and catalogue accounts, because the lender and the supplier are connected. It is general-purpose borrowing, where you receive cash and spend it as you choose, that falls outside the protection.
A widely misunderstood point concerns the £100 threshold. It refers to the cash price of the item, not the amount you put on the card. You do not need to pay £100 on the credit card to be covered. Paying a deposit, or even a token amount, is enough, provided the item itself costs more than £100 and no more than £30,000. If you order a £660 sofa and pay a £60 deposit by credit card, the whole £660 is covered if the retailer goes under. This makes the partial-payment strategy genuinely useful: put a small part of a large purchase on a card to secure the protection, fund the rest through a loan or savings, and clear the card portion promptly to avoid interest.
Two limits are worth noting. The threshold applies per item, so two £60 purchases that together exceed £100 do not qualify. And for purchases under £100, chargeback may still offer some recourse. Chargeback is a voluntary scheme rather than a legal right, and is available on credit and debit cards. Section 75 makes a credit card the stronger choice for holiday bookings with smaller operators, custom-made goods, services paid for in advance, and purchases from overseas or less-established sellers. For routine purchases from well-known retailers, the protection matters less and the decision reverts to cost.
How personal loans and credit cards compare across five dimensions
The table below brings together the five main factors that determine which product is more suitable for a given situation. Each factor is explored in the sections above.
| Dimension | Personal loan | Credit card |
|---|---|---|
| Total cost | Fixed and known from the start. Lower APR than credit cards for most borrowers, though small loans are proportionally expensive. Total cost increases with term length but is always calculable. | Zero during a 0% promotional period. Potentially very high if the balance is not cleared before the revert rate applies. Minimum payments can multiply the total cost several times over. |
| Flexibility | Low. The monthly payment is fixed for the full term. Overpayments and early repayment are possible, sometimes with a small charge. | High. The borrower can pay any amount above the minimum each month. This flexibility is an advantage for disciplined borrowers and a risk for those who default to minimum payments. |
| Consumer protection | No Section 75 protection on general-purpose borrowing. The claim for faulty goods is against the retailer only. Point-of-sale finance is treated differently. | Section 75 protection where the item costs more than £100 and not more than £30,000. The card provider is jointly liable if the retailer fails to deliver or the goods are faulty. |
| Credit file impact | Hard search at application. Monthly payment record throughout the term. Settled account visible for six years. Fixed debt with a clear end date. | Hard search at application. Monthly balance and payment record visible. High credit utilisation (using a large proportion of the credit limit) can reduce the credit score. |
| Behavioural risk | Low. The structure enforces consistent repayment. The debt has a defined end date. No option to revolve or extend without a new agreement. | Higher. The revolving nature means the balance can increase as well as decrease. Minimum payments create the illusion of progress while extending the debt for years. |
Deciding which is right for your situation
The decision is not about which product is universally better. It is about which product fits the specific situation. The following questions provide a practical framework for making the comparison.
First, can you clear the full balance within a 0% promotional period? If yes, and if you have access to a 0% card with a long enough promotional window, the credit card is the cheaper option. Set up a standing order for a fixed monthly amount that clears the balance before the promotional period ends, and the borrowing costs nothing. The comparator above calculates that figure for you. If you are not confident the balance will be cleared in time, a personal loan removes the risk of the revert rate.
Second, is Section 75 protection important for this purchase? If you are buying goods or services where the risk of non-delivery or supplier failure is meaningful, a credit card gives you a claim against the card provider that a general-purpose loan does not. Even a token payment on the card triggers the protection. For purchases where this risk is low, Section 75 is less of a factor.
Third, do you trust yourself to maintain fixed payments on a credit card, or will you default to the minimum? This is the question most borrowers are reluctant to answer honestly, and it is the one that makes the biggest difference to the total cost. If you know from experience that you tend to pay the minimum, a personal loan is the structurally safer choice: the fixed payment removes the option to slide, and the total cost is locked in from the start. The guide to is a personal loan right for you covers the broader decision framework for anyone still weighing up whether borrowing is the right step at all, and personal loans vs buy now pay later covers a third structure with a similar deferred-interest risk.

When is a credit card cheaper than a personal loan?
A credit card is cheaper when the balance is cleared quickly, either within a 0% promotional period, in which case no interest is charged at all, or within a few months at a payment high enough to keep the total interest below the loan’s. For small amounts under £1,000 cleared within three to six months, a card is almost always cheaper, because personal loan pricing is banded and the smallest loans carry the highest rates.
As the amount increases and the clearance period extends, the personal loan becomes increasingly competitive. At £3,000 and above, unless a 0% card is available and the balance will genuinely be cleared within the promotional window, a personal loan at a mainstream rate is typically cheaper. The comparator above gives the exact crossover: the monthly card payment at which the two products cost the same for your particular figures.
What monthly card payment should I enter?
Enter the amount you would actually pay each month, not what you hope to pay. If you would set up a standing order for £150, enter £150. If you would pay whatever the statement asks for, switch to the “minimum only” mode instead. That models the contractual minimum, which declines with the balance and is what produces the multi-decade clearance times.
Trying different amounts is the most useful way to use the tool. Moving the payment from £50 to £200 changes the clearance time and total interest dramatically. If you enter an amount below the contractual minimum, the tool will tell you and use the minimum instead, since that is the least a provider would accept.
Can I use a credit card and a personal loan together for the same purchase?
Yes, and it is often the best of both. Pay part of the purchase on a credit card to secure Section 75 protection, and fund the remainder with a personal loan or savings. There is no minimum amount you need to put on the card. A deposit or even a token payment is enough, provided the item’s cash price is more than £100 and not more than £30,000. The Section 75 claim then covers the full purchase price, not just the portion paid on the card.
This works well for holidays, furniture, building work, and services paid for in advance, where the risk of the supplier failing to deliver is real. It matters less for purchases from well-established retailers. Whatever goes on the card should be cleared promptly to avoid interest at the card’s standard rate.
What happens if I cannot clear my 0% balance before the promotional period ends?
The remaining balance starts accruing interest at the card’s standard purchase rate, typically between 20% and 25% APR and sometimes higher. There is no gradual transition. On the day the promotional period ends, the whole remaining balance begins incurring interest. If £2,000 remains at a 22% revert rate, the monthly interest charge is about £37, and that is added to the balance if only the minimum is paid.
If it becomes clear the balance will not be cleared in time, there are two options. Apply for a 0% balance transfer card and move the remaining balance to a new promotional period, usually for a transfer fee of 1% to 3%. Or take a personal loan to clear the remainder at a lower rate than the revert rate. Both cost less than paying the revert rate over an extended period, and both are easier to arrange before the promotional period ends than after.
Is a personal loan better than a credit card for debt consolidation?
For consolidating existing credit card debt, a personal loan can be more cost-effective than a 0% balance transfer card if the total balance is large, the available 0% period is short, or the transfer fee is high. A loan at a mainstream rate over three years will cost less in total interest than a card at 22% over the same period, and the fixed structure ensures the debt is cleared by the end of the term.
The risk is behavioural. Once the card balances are cleared by the loan, the cards are available again. If new spending accumulates while the loan is being repaid, the borrower ends up with more total debt than before. If consolidation is the goal, closing or reducing the limits on the cleared cards is the most effective safeguard. The debt consolidation loans section covers this in more depth, and the credit card to personal loan calculator models the saving on an existing balance.
Does applying for a credit card affect my credit score differently from applying for a loan?
Both trigger a hard credit search, and the immediate impact is similar. The search is recorded and visible to other lenders for 12 months, and a single search for either product has a relatively small effect. The difference is in how the account appears once opened. A credit card shows as a revolving facility with a limit and a fluctuating balance. A personal loan shows as an instalment account with a fixed balance that decreases over time.
High credit card utilisation, meaning using a large proportion of the available limit, can reduce a credit score. A loan balance decreases with every payment and is generally viewed more neutrally by scoring models. The guide to how personal loans affect your credit score covers the credit file mechanics in detail.
Squaring Up
A 0% credit card is the cheapest way to borrow a small amount over a short period, provided the balance is cleared before the promotional rate ends. For larger amounts, longer repayment periods, or borrowers who know they are likely to default to minimum payments, a personal loan is almost always cheaper and structurally safer. Section 75 protection is a genuine credit card advantage where the risk of supplier failure is meaningful, and because the £100 threshold applies to the item rather than the card payment, a token amount on the card secures it without committing the whole purchase to card interest.
The honest question is not which product has the lower APR. It is which product will result in the lower total cost, given how you are actually likely to use it.

What changed in this update
This guide now includes the interactive personal loan vs credit card comparator, bringing the explanation and the modelling together on one page. The tool gained a minimum-payment mode alongside the existing fixed-payment view, a breakeven figure showing the monthly card payment at which the two products cost the same, and a calculation of the payment needed to clear a balance within a 0% promotional period. Loan rate guidance now reflects the banded structure of UK personal loan pricing, where rates fall sharply above £5,000, and card rate context has been updated against the latest Bank of England averages.
Worked examples have been refreshed and expanded, with show-the-working dropdowns added to the £5,000 comparison and the minimum payment scenario so every figure can be traced. Minimum payments are now modelled on the greatest-of structure most UK providers set out in their summary box. A new section covers the FCA persistent debt rules, which set out what a provider must do when a balance is being repaid slowly, and the Section 75 material has been expanded to cover the £100 threshold, point-of-sale finance, and the per-item limit.
Tool usability improved: exact figures can now be typed into any input as well as set by slider, the payment range scales with the amount borrowed, colour contrast was raised across the interface, and results are announced to screen readers as they update.
This article and tool are for informational purposes only and do not constitute financial advice. All rate figures, worked examples, and cost comparisons are illustrative and do not represent any specific lender or credit card provider. Credit card minimum payments are modelled as the greatest of 1% of the balance plus interest, 2.5% of the balance, or £5, which reflects the structure most UK providers use but may differ by provider. Section 75 protection, cashback, and reward benefits are not modelled. The rate, terms, and promotional period available to any individual will depend on their credit profile and the provider’s own criteria. Missed repayments on either product can affect your credit rating and may result in further action.
