You are buying a car and you need to decide how to pay for it. The dealership will offer you finance at the point of sale, typically hire purchase (HP) or personal contract purchase (PCP), and these may include manufacturer-subsidised promotional rates. Alternatively, you could arrange a personal loan independently and arrive at the dealership as a cash buyer. Each route works differently, costs differently, and carries different risks. There is no single answer that applies to every purchase.
This guide compares the four main routes to funding a car: a personal loan from a bank or lender, hire purchase through the dealer, PCP through the dealer, and dealer-arranged personal loans. It covers ownership, total cost, flexibility, consumer protection, and the practical question of whether the cash buyer advantage is worth more or less than a subsidised dealer finance rate. All figures are illustrative. This article is for mainstream borrowers comparing their options. For borrowers with credit difficulties, the guide to bad credit car financing covers the specialist options available.

A personal loan gives you outright ownership from day one. With HP you own the car after the final payment. With PCP you may never own it at all.
Ownership is the biggest structural difference between the options. A personal loan means you own the car the moment you pay for it. HP transfers ownership after the last instalment plus a small option-to-purchase fee. PCP gives you the option to own the car at the end by paying a balloon payment, but most PCP customers hand the car back or roll into a new deal, meaning they paid for the use of the car but never owned it. If owning the car outright matters to you, this distinction narrows the field quickly.

A manufacturer-subsidised 0% PCP deal can be genuinely cheaper than any loan. Do not assume a personal loan is always the lowest-cost route.
Manufacturers periodically offer 0% APR or heavily subsidised PCP and HP deals to move stock. When these are available on the car you want, the total cost of the finance can be lower than the interest on a personal loan for the same amount. The subsidy is the manufacturer’s marketing cost, not the dealer’s. These deals are genuine, but they come with conditions: the car must be new, the model must be in the promotion, and the PCP terms (mileage limits, balloon payment, condition standards) still apply.

Paying with a personal loan makes you a cash buyer. That negotiating position can offset the interest cost of the loan.
A buyer who arrives at a dealership with cash (or the equivalent, a pre-arranged personal loan) can negotiate on price in a way that a buyer relying on dealer finance cannot. The dealer does not need to factor in a finance commission, and the buyer is not tied to the dealer’s lending panel. On a used car or a new car without a manufacturer promotion, the price reduction negotiated as a cash buyer can partially or fully offset the interest cost of the personal loan.
Four ways to finance a car
The four main routes to financing a car purchase each have different mechanics, different cost structures, and different implications for ownership. Understanding the structural differences before comparing costs is essential, because the cheapest option on paper may not be the best fit for the buyer’s actual situation.
| Feature | Personal loan | Hire purchase (HP) | PCP | Dealer personal loan |
|---|---|---|---|---|
| How it works | Borrow from a bank or lender. Pay for the car outright. Repay the loan in fixed monthly instalments. | Pay a deposit to the dealer. Repay the remaining balance plus interest in fixed monthly instalments. Ownership transfers after the final payment. | Pay a deposit. Make monthly payments based on the car’s depreciation, not its full value. At the end, pay a balloon payment to keep the car, hand it back, or use any equity toward a new deal. | The dealer arranges an unsecured loan through a partner lender. Functions like a standard personal loan but arranged at the point of sale. |
| Ownership | You own the car from day one. | The finance company owns the car until the final payment plus an option-to-purchase fee (typically nominal). | The finance company owns the car throughout. You own it only if you pay the balloon payment at the end. | You own the car from day one (the loan is unsecured). |
| Deposit | No deposit required for the loan. You may choose to put savings toward the purchase to reduce the loan amount. | Typically 10% or more of the car’s value. A larger deposit reduces the monthly payment and the total interest. | Typically 10% or more. A larger deposit reduces the monthly payment and can reduce the balloon payment. | No deposit required for the loan itself. |
| Monthly payment | Fixed. Based on the full loan amount, APR, and term. | Fixed. Based on the amount financed (price minus deposit), APR, and term. | Lower than HP because payments cover depreciation, not the full value. The balloon payment defers a large portion of the cost. | Fixed. Based on the loan amount, APR, and term. |
| What happens at the end | The loan is repaid. You own the car. No further payments. | Pay the option-to-purchase fee (typically £1 to £10). You own the car. No further payments. | Three choices: pay the balloon payment and keep the car, hand the car back (subject to mileage and condition standards), or use any equity as a deposit on a new PCP deal. | The loan is repaid. You own the car. No further payments. |
| Flexibility | No mileage limits. No condition requirements. You can sell the car at any time. | No mileage limits. No condition requirements. You cannot sell the car without settling the finance first. | Annual mileage limit (typically 6,000 to 12,000 miles). Excess mileage charges apply. Car must meet fair wear and tear standards at return. | No mileage limits. No condition requirements. You can sell the car at any time. |
The cash buyer advantage
When you fund a car with a personal loan, the money is in your bank account before you visit the dealer. To the dealer, you are a cash buyer. You are not relying on their finance panel, you are not waiting for an approval decision, and the dealer does not need to factor a finance commission into the transaction. This gives you negotiating leverage that is not available to a buyer who needs the dealer to arrange the finance.
The practical impact depends on the type of purchase. On a used car, where there is typically more room for negotiation, the cash buyer advantage can be significant. A dealer selling a used car at £12,000 knows that a cash buyer is a certain sale with no finance approval risk. Offering a discount of £500 to £1,000 to close the deal is a rational decision for the dealer, and that discount can offset a meaningful proportion of the interest on a personal loan for the same amount.
On a new car with a manufacturer promotion, the cash buyer advantage is weaker. The manufacturer has set the promotional terms, and the dealer may earn a commission for arranging the finance that they would lose if the buyer pays cash. In some cases, the dealer may prefer the finance route because the manufacturer’s contribution makes it more profitable. This is one reason why a subsidised 0% PCP deal on a new car can be genuinely cheaper than a personal loan: the manufacturer is subsidising the finance, and the buyer who insists on paying cash may miss out on that subsidy.
A note on dealer finance commissions: the way dealers have historically been paid commission for arranging car finance has been the subject of significant regulatory action by the FCA. Discretionary commission arrangements, where the dealer could influence the interest rate charged to the consumer and receive a higher commission for setting a higher rate, were banned in 2021. The FCA has since confirmed an industry-wide redress scheme for customers who were treated unfairly under these arrangements between 2007 and 2024. This does not affect the buyer’s decision about how to finance a car today, but it does underline why transparency about any commission the dealer receives is important. If you are taking dealer-arranged finance, you can ask the dealer to confirm in writing what commission, if any, is payable on the arrangement.
When a personal loan is the cheaper option
A personal loan tends to be the more cost-effective route in three situations: used car purchases, new car purchases without a manufacturer promotion, and any purchase where the buyer values outright ownership and flexibility over a lower monthly payment.
For used cars, the comparison is often straightforward. Dealer-arranged HP and PCP on used cars typically carry higher APRs than the rates available on a personal loan from a mainstream lender, because the dealer’s finance panel prices in the higher risk of lending on a depreciating asset and includes a commission. A borrower with a reasonable credit profile might receive a personal loan at an illustrative APR in the range of 5% to 10%, while dealer-arranged HP on the same used car might be offered at 8% to 15% or higher. The exact figures depend on the lender, the car, and the borrower’s profile, but the direction of the comparison is consistent.
For new cars without a manufacturer promotion, the same pattern applies. The dealer’s standard finance rate is typically higher than what the buyer could obtain independently. The cash buyer advantage (the ability to negotiate on price) compounds the saving from the lower loan rate. The car finance comparator allows side-by-side comparison of different finance routes for any car price, deposit, and term.
When dealer finance is genuinely cheaper
Manufacturer-subsidised finance deals can be genuinely cheaper than any personal loan, and dismissing them as a sales tactic would be a mistake. When a manufacturer offers 0% APR on PCP or HP for a specific model, the finance is interest-free. A personal loan for the same amount, at any positive APR, costs more. The subsidy is the manufacturer’s marketing cost, designed to move stock, and the buyer benefits directly.
These promotions are most common on new cars, particularly models the manufacturer is keen to sell in volume or outgoing models being cleared before a new version launches. The 0% rate is genuine: the buyer pays the price of the car divided by the number of payments, with no interest added. On a PCP deal, the monthly payments cover the depreciation only, and the balloon payment at the end represents the expected residual value.
The conditions that come with these deals are worth understanding before accepting. The promotion applies to a specific model or range, not to any car the buyer chooses. The PCP terms include a mileage limit and condition standards. And the promotional rate is available only to buyers who meet the manufacturer’s finance company’s credit criteria, which may differ from the criteria used by independent personal loan lenders. It is possible to be approved for a personal loan and declined for a manufacturer’s promotional PCP, or vice versa.
For buyers who want a specific new car that is covered by a manufacturer promotion, and who can live with the PCP terms (mileage limit, condition standards, balloon payment decision at the end), the subsidised deal is typically the cheapest route. The next section explains the risks that come with PCP specifically.
PCP: what the monthly payment does not tell you
PCP has become the dominant form of new car finance in the UK, largely because it produces the lowest monthly payment of any finance route. The monthly payment is lower because it covers only the car’s depreciation over the agreement term, not the full value. The remainder, known as the guaranteed minimum future value (GMFV) or balloon payment, is deferred to the end of the agreement. This structure makes an expensive car look affordable on a monthly basis, but it conceals three risks that the monthly figure does not reveal.
The first risk is the balloon payment. At the end of the PCP agreement, the buyer must choose: pay the balloon payment and keep the car (which can be 30% to 50% of the original price), hand the car back and walk away with nothing, or use any positive equity (the difference between the car’s market value and the balloon payment) as a deposit on a new deal. Most PCP customers choose the third option, which means they are always making payments on a car and never reaching the point of owning one outright. Over a decade of rolling PCP agreements, a buyer can spend more in total finance payments than the car was ever worth, without ever owning a vehicle.
The second risk is mileage limits. PCP agreements include an annual mileage allowance, typically between 6,000 and 12,000 miles per year. If the buyer exceeds this allowance, an excess mileage charge applies at the end of the agreement, typically between 3p and 30p per mile depending on the car and the agreement. On a three-year PCP with an 8,000-mile annual allowance, driving 12,000 miles per year would result in an excess of 12,000 miles over the term. At an illustrative charge of 10p per mile, that is £1,200 payable at the end. This charge is in addition to the monthly payments already made.
The third risk is the condition requirement. When the car is handed back at the end of a PCP agreement, it must meet the finance company’s fair wear and tear standards. Damage beyond normal wear, including dents, scratches, interior stains, tyre condition, and alloy wheel damage, is charged to the customer. The assessment is carried out by the finance company or its agent, and the definition of “fair wear and tear” follows industry guidelines (typically the BVRLA Fair Wear and Tear Guide) but can still result in unexpected charges.
Making the decision: a practical framework
The right finance route depends on the type of car, the buyer’s priorities, and the specific terms available. The following framework covers the most common scenarios.
If you are buying a used car and want to own it outright, a personal loan is typically the strongest option. The rate is likely to be lower than dealer HP, the cash buyer advantage gives negotiating leverage on the price, and you own the car from day one with no mileage limits or condition requirements. Use the personal loan repayment calculator to model the monthly payment and total cost before visiting the dealer.
If you are buying a new car with a manufacturer 0% promotion, the subsidised deal is typically the cheapest option, provided you can live with the PCP terms. Check the mileage allowance against your actual annual mileage. Check the balloon payment amount and decide whether you would want to pay it at the end or hand the car back. If the mileage limit is too low or the balloon payment is uncomfortably large, a personal loan may still be the better route despite the interest cost.
If you are buying a new car without a promotion and want to own it, compare the dealer’s HP rate against the rate available on a personal loan using a soft-search eligibility check. If the personal loan rate is lower, the cash buyer advantage compounds the saving. If the rates are similar, HP may be more convenient because the finance is arranged at the point of sale and the deposit can reduce the amount financed.
For a broader assessment of whether a personal loan is the right borrowing product for your situation, beyond car purchases specifically, the guide to is a personal loan right for you covers the decision framework in full.

Is a personal loan always cheaper than car finance?
No. A manufacturer-subsidised 0% PCP or 0% HP deal is genuinely cheaper than any personal loan because no interest is charged. These promotions are offered by manufacturers to move stock and are available on specific new models. When the car you want is covered by such a promotion and you meet the finance company’s credit criteria, the subsidised deal is the lowest-cost route. A personal loan is typically cheaper than standard (non-promotional) dealer finance, where the APR on HP or PCP at the dealer is higher than the rate available on a personal loan from an independent lender.
The comparison also depends on whether the buyer values outright ownership. A personal loan is more expensive than a 0% PCP deal in terms of the monthly payments, but at the end of the loan the buyer owns the car. At the end of a PCP deal, the buyer must pay a balloon payment to own the car, hand it back, or roll into a new agreement. Over time, rolling PCP deals can cost more in total than a personal loan, because the buyer never stops making payments.
What is the cash buyer advantage and how much is it worth?
The cash buyer advantage is the negotiating leverage that comes from not needing the dealer to arrange finance. A buyer who has pre-arranged a personal loan can negotiate on the car’s price as if they were paying from savings, because the dealer receives the full amount upfront. On a used car, this leverage can produce a discount of several hundred pounds, depending on the dealer’s margin on the vehicle. On a new car without a manufacturer promotion, a smaller but still meaningful discount may be available.
The value of the advantage depends on the specific deal, the car’s margin, and the buyer’s willingness to negotiate. It is not a guaranteed saving, and some dealers are more flexible than others. However, it is a structural advantage that is not available to buyers who rely on the dealer to arrange finance, because the dealer has less incentive to reduce the price when they are also earning a commission on the finance arrangement.
Can I sell a car that is on HP or PCP?
You cannot sell a car that is subject to an HP or PCP agreement without first settling the finance. The finance company owns the car (or has a legal interest in it) until the final payment is made. Selling a car with outstanding finance without disclosing this to the buyer is a criminal offence. If you want to sell the car before the finance is fully repaid, you must contact the finance company, request a settlement figure, and pay this amount before or at the point of sale. Any difference between the sale price and the settlement figure is either your surplus or your shortfall.
With a personal loan, there is no restriction on selling the car at any time, because you own it outright from day one and the loan is unsecured. The loan repayments continue regardless of whether you keep the car, but you are free to sell it, trade it, or dispose of it as you wish. This flexibility is one of the structural advantages of funding a car with a personal loan rather than dealer finance.
What happens if I go over the mileage limit on a PCP deal?
If you exceed the annual mileage allowance specified in a PCP agreement, an excess mileage charge is applied when the car is handed back at the end of the agreement. The charge is a fixed amount per mile, typically between 3p and 30p depending on the car and the agreement terms. The charge applies to every mile over the total mileage allowance for the full agreement term, not just the amount over in the final year.
For example, a three-year PCP with an 8,000-mile annual allowance gives a total allowance of 24,000 miles. If the car has covered 36,000 miles at the end of the agreement, the excess is 12,000 miles. At an illustrative charge of 10p per mile, the excess mileage fee would be £1,200. This charge is in addition to the monthly payments already made throughout the agreement. If you know your annual mileage is likely to exceed the standard allowance, it is worth negotiating a higher mileage limit at the outset (which will increase the monthly payment) or considering a personal loan or HP instead, where no mileage limit applies.
Does the voluntary termination right apply to all car finance?
The voluntary termination right under the Consumer Credit Act applies to HP and PCP agreements but not to personal loans. Under this right, once the buyer has paid at least 50% of the total amount payable under the agreement (including any deposit and balloon payment in the case of PCP), they can hand the car back and walk away from the remaining payments. The car must be in reasonable condition, and the buyer may be liable for any damage beyond fair wear and tear.
This right does not apply to a personal loan because the loan is a separate agreement from the car purchase. The loan repayments continue regardless of what happens to the car. However, the buyer who has funded the car with a personal loan is free to sell the car at any time and use the proceeds to repay part or all of the loan. The early repayment charge caps under the Consumer Credit Act (up to 1% of the amount repaid early, or 0.5% in the final year) apply to the loan settlement.
Squaring Up
The right way to finance a car depends on the car, the deal available, and what matters most to the buyer. A personal loan gives outright ownership from day one, no mileage limits, no condition requirements, and the negotiating leverage of a cash buyer. Manufacturer-subsidised 0% deals on new cars can be genuinely cheaper than any loan and should not be dismissed. Standard dealer finance on used cars is typically more expensive than an independently arranged personal loan. PCP produces the lowest monthly payment but defers a large portion of the cost to the end, and most buyers never own the car.
