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. 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 years of repayment.
Credit card minimum payments are typically set at 1% to 2.5% of the balance plus interest, or a fixed minimum of around £5 to £25. Paying only the minimum on a £3,000 balance at a typical credit card APR can take over 20 years to clear and cost more in interest than the original amount borrowed. A personal loan for the same amount over three years would cost a fraction of that. The structure of the loan, with its fixed payments and set end date, prevents this from happening.

Credit cards offer Section 75 protection on purchases over £100. Personal loans do not. This is a genuine advantage worth factoring in.
If you buy something costing over £100 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 protection does not apply to purchases funded by a personal loan. For high-value purchases where the risk of something going wrong is meaningful, this can be a deciding factor.
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 personal loan vs credit card comparator can model the total cost of both options side by side for any amount, APR, and repayment period.
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. For example, a £2,000 purchase on a card with an 18-month 0% period requires payments of approximately £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 7% APR over 18 months would cost approximately £2,107, with £107 going to interest. The credit card saves £107.
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 £1,000 of the original £2,000 balance remains when the 0% period ends, that £1,000 is now accruing interest at the revert rate. If only minimum payments are made from that point, the remaining balance can take years to clear and the total interest paid can exceed the amount originally left on the card. The 0% period is only an advantage if it is used to clear the balance, not to defer it.
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 lower than credit card standard rates. A borrower with a reasonable credit profile might receive a personal loan at an illustrative APR in the range of 5% to 10%. A standard credit card purchase rate for the same borrower is more likely to sit between 20% and 25% APR. The difference in annual cost on a £5,000 balance is substantial, and it compounds over every month the balance is outstanding.
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 7% APR | Credit card at 22% APR |
|---|---|---|
| Monthly payment | £154 (fixed for 36 months) | Varies. Minimum payments decrease as balance falls, extending the repayment period. |
| Total repaid | Approximately £5,559 | Approximately £6,850 if repaid at £154/month. Significantly more if only minimum payments are made. |
| Total interest | Approximately £559 | Approximately £1,850 at fixed £154/month. Could exceed £5,000 at minimum payments over 20+ years. |
| 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 £1,291 in favour of the personal loan. At minimum payments on the credit card, the difference would be substantially larger. 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 in detail.
The minimum payment trap
This is the single biggest cost risk on a credit card, and it is the reason that a credit card can end up being dramatically more expensive than a personal loan for the same amount. Credit card minimum payments are typically calculated as a percentage of the outstanding balance (usually 1% to 2.5%) plus interest, or a fixed minimum amount (usually £5 to £25), whichever is greater. As the balance falls, the minimum payment falls with it. This means the borrower pays less each month, which feels like progress, but the declining payment means the balance is being repaid more and more slowly.
The arithmetic is stark. On a £3,000 balance at an illustrative credit card APR of 22%, paying only the minimum each month can take over 25 years to clear. The total interest paid over that period can exceed the original amount borrowed, meaning the borrower pays back more than £6,000 for a £3,000 purchase. The same £3,000 on a personal loan at an illustrative 7% APR over three years would cost approximately £334 in interest, with the debt guaranteed to be cleared in 36 months.
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.
Section 75 protection: a genuine credit card advantage
Section 75 of the Consumer Credit Act 1974 provides a powerful form of consumer protection that is unique to credit cards. If you buy something costing between £100 and £30,000 on 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. This means you can claim against the card company directly, even if the retailer has ceased trading.
This protection does not apply to purchases funded by a 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. The loan repayments continue regardless. For high-value purchases where the risk of non-delivery or supplier failure is meaningful, Section 75 is a genuine advantage that can justify using a credit card even if the interest cost is slightly higher.
A practical strategy used by some borrowers is to pay the deposit or a small portion of the purchase on a credit card (enough to trigger the £100 threshold for Section 75 coverage) and fund the remainder through a personal loan or savings. This secures the consumer protection without incurring credit card interest on the full amount. The Section 75 claim covers the full purchase, not just the amount paid on the card, provided at least part of the transaction was on the card and the total purchase price was between £100 and £30,000.
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. 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. The borrower’s claim for faulty goods is against the retailer only. | Section 75 protection on purchases between £100 and £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. 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 personal loan does not. Even a partial payment on the card can trigger the protection. For purchases where this risk is low (a car from a reputable dealer, a well-established retailer), 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 on credit cards, a personal loan is the structurally safer choice. The fixed payment removes the option to slide into minimum payments, 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.

Can I use a credit card and a personal loan together for the same purchase?
Yes. A common approach is to pay the deposit or a small portion of a purchase on a credit card (at least £100 to trigger Section 75 protection) and fund the remainder with a personal loan or savings. This gives the consumer protection of the credit card without incurring credit card interest on the full amount. The Section 75 claim covers the full purchase price, not just the amount paid on the card, provided the total purchase was between £100 and £30,000.
This approach works well for purchases like holidays, furniture, or services where there is a risk the supplier might not deliver. It is less relevant for purchases from well-established retailers where the risk of non-delivery is low. The credit card portion should be repaid promptly to avoid interest charges at the card’s standard rate.
What happens if I cannot clear my 0% credit card balance before the promotional period ends?
The remaining balance starts accruing interest at the card’s standard purchase rate, which is typically between 20% and 25% APR. There is no gradual transition. On the day the promotional period ends, the full remaining balance begins incurring interest at the revert rate. If £2,000 remains on the card at a 22% revert rate, the monthly interest charge is approximately £37, and this amount is added to the balance if only the minimum payment is made.
If it becomes clear that the balance will not be cleared in time, there are two options. The first is to apply for a 0% balance transfer card and move the remaining balance to a new promotional period. This may involve a balance transfer fee, typically 1% to 3% of the amount transferred. The second is to take out a personal loan to clear the remaining balance at a lower APR than the credit card revert rate. Both options cost less than paying the revert rate over an extended period.
Is a personal loan better than a credit card for debt consolidation?
For consolidating existing credit card debt, a personal loan can be a more cost-effective route than a 0% balance transfer card if the total balance is large, the available 0% period is short, or the balance transfer fee is high. A personal loan at an illustrative 7% APR over three years will cost less in total interest than a credit card at 22% APR over the same period, and the fixed repayment structure ensures the debt is cleared by the end of the term.
The risk with using a personal loan to consolidate credit card debt is behavioural. Once the card balances are cleared by the loan, the cards are available to use again. If new spending accumulates on the cards 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 credit limits on the cleared cards is the most effective way to prevent this. The debt consolidation loans section covers this decision in more depth.
Does applying for a credit card affect my credit score differently from applying for a loan?
Both a credit card application and a personal loan application trigger a hard credit search, and the impact on the credit file is similar. The search is recorded and visible to other lenders for 12 months. A single search for either product has a relatively small effect. The difference is in how the account appears once it is opened. A credit card appears as a revolving credit facility with a credit limit and a fluctuating balance. A personal loan appears as an instalment account with a fixed balance that decreases over time.
High credit card utilisation, meaning using a large proportion of the available credit limit, can reduce a credit score. A personal loan balance, by contrast, decreases with every payment and is generally viewed more neutrally by scoring models. For this reason, some borrowers find that a personal loan has a more stable effect on their credit profile than a credit card with a fluctuating balance. The guide to how personal loans affect your credit score covers the credit file mechanics in detail.
Are there any purchases where a credit card is always the better choice?
Section 75 protection makes a credit card the stronger choice for any purchase between £100 and £30,000 where there is a meaningful risk that the goods might not arrive, might be faulty, or the seller might go out of business. This includes holiday bookings (particularly with smaller operators), custom-made goods, services paid for in advance, and purchases from overseas sellers. The joint liability of the card provider means you have a direct claim even if the retailer is no longer trading.
For very small purchases under £100, Section 75 does not apply, but chargeback (a separate, non-statutory process available on both credit and debit cards) may still offer some recourse. For routine purchases where the risk of non-delivery is low, the credit card’s consumer protection advantage is less relevant, and the decision reverts to the cost and behavioural factors described in this guide.
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 for purchases where the risk of supplier failure is meaningful, and the partial-payment strategy can secure that protection without committing the full amount to the card.
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.
