Car loan vs car finance: which is cheaper, and what you give up
The short answer: a personal loan is often the cheaper way to buy a car if your credit record is good. You own the car from day one and can sell it whenever you like. Dealer finance (Hire Purchase or PCP) is usually a little dearer, but it comes with protections a loan doesn’t: you can hand the car back once you’ve paid half, and on PCP the car’s future value is guaranteed. On a £20,000 car with £2,000 down over four years, a loan at 6.9% APR costs £22,566 in total, against £23,697 on Hire Purchase at 9.9%. That’s a saving of about £1,131. At an average loan rate, though, the gap all but disappears.
How each one works
- Personal loan. A bank or lender pays you the money, you buy the car outright, and you repay the loan in fixed monthly payments. The loan isn’t tied to the car.
- Hire Purchase (HP). You pay a deposit and fixed monthly payments arranged through the dealer. The finance company owns the car until the last payment, then it’s yours.
- PCP. Like HP, but a large balloon payment is left until the end, so monthly payments are lower. You can pay the balloon, hand the car back or part-exchange it. See our balloon payment guide.
The same car, four ways
| £20,000 car, £2,000 deposit, 48 months | APR | Monthly | Total interest | Total cost |
|---|---|---|---|---|
| Personal loan, good credit | 6.9% | £428.46 | £2,566 | £22,566 |
| Personal loan, average rate | 9.66% | £450.13 | £3,606 | £23,606 |
| Hire Purchase | 9.9% | £452.02 | £3,697 | £23,697 |
| PCP, keep the car (£8,000 balloon) | 9.9% | £314.30 | £5,087 | £25,087 |
| Personal loan, fair credit | 14.9% | £491.60 | £5,597 | £25,597 |
The 9.66% line is the Bank of England’s average effective rate on new personal loans in May 2026. Advertised rates are often much lower, but the rules only require a lender to expect at least 51% of successful applicants to get the representative APR. Many people are offered more, especially on smaller loans.
The lesson is that the type of borrowing matters less than the rate you’re offered. A loan only wins if you can get a rate clearly below the dealer’s.
What you gain and give up
| Personal loan | Hire Purchase | PCP | |
|---|---|---|---|
| Who owns the car | You, from day one | Finance company until the last payment | Finance company until you pay the balloon |
| Secured on the car | No | Yes | Yes |
| Hand it back once you’ve paid half | No | Yes, voluntary termination | Yes, but the balloon counts, so it’s later |
| Guaranteed future value | No | No | Yes |
| Mileage limits | None | None | Yes, with excess charges |
| Sell whenever you like | Yes | Only after settling | Only after settling |
| Faulty car claim against | The seller | The finance company (legally the supplier) and dealer | The finance company and dealer |
| Carmaker deals (0% APR, deposit contributions) | No | Sometimes | Often |
| Bargaining power | Cash buyer | Finance deal | Finance deal |
Three things people miss
1. Dealer finance gives you a stronger claim if the car is faulty
On Hire Purchase and PCP the finance company buys the car and supplies it to you, so it’s legally the supplier under the Consumer Rights Act 2015. If the car turns out to be faulty, you can claim against the finance company, which is usually a large, regulated lender, as well as the dealer. With a personal loan your only claim is against whoever sold you the car. That can matter a lot with a small used car dealer.
2. Carmaker offers only come through finance
Manufacturers sometimes subsidise their own finance with 0% or low APR deals, or put a “deposit contribution” of £1,000 to £3,000 towards PCP. A cash or loan buyer can’t get these, although they can sometimes negotiate a discount instead. Compare the whole deal: price, contribution, APR and total amount payable.
3. A loan leaves you free to sell
With a loan you can sell the car at any time and keep any money left after clearing the loan. On HP and PCP you must settle the finance first. That’s easy through a dealer part-exchange, more fiddly in a private sale.
Commission and how dealers are paid
Dealers are usually paid commission by the lender when you take their finance. Since 28 January 2021 the Financial Conduct Authority has banned commission that rises with the interest rate the dealer sets, which removed the incentive to put customers on higher rates. Dealers still have to tell you whether they’re paid commission and how it works. Ask, and get a loan quote before you visit so you know what a fair rate looks like.
Which suits you
| Choose a personal loan if | Choose Hire Purchase if | Choose PCP if |
|---|---|---|
| Your credit is good and you can get a rate clearly below the dealer’s. You want no mileage limits and the freedom to sell. You’re buying privately or from a small dealer | You want to own the car at the end, like the protection of voluntary termination, or there’s a good dealer rate. Your credit record is patchy and the dealer’s lender accepts you | You like to change cars every three or four years, want the lowest monthly payment, or want the guaranteed future value as insurance against the car losing value |
Before you sign either
- Get a personal loan quote with a soft-search eligibility checker, so your credit file isn’t marked.
- Ask the dealer for the APR, the total amount payable and any fees, in writing.
- Put both into the car finance calculator and compare the totals, not just the monthly figure.
- If you’re buying with a loan, negotiate the price as a cash buyer.
- Check you can afford it. Our guide to how much car you can afford works it out by salary.
Common mistakes
- Comparing an advertised loan rate with the dealer’s actual offer. Get your real loan rate first.
- Taking a loan over a longer term than the dealer finance just to get a lower payment, and paying more overall.
- Forgetting the deposit contribution on a PCP offer when comparing with a loan.
- Using a loan for a car from a small dealer and losing the stronger claim against a finance company if it goes wrong.
- Taking on a car payment just before applying for a mortgage.

Common questions
Is a personal loan cheaper than car finance?
Often, if you have a good credit record. Personal loans of £7,500 to £25,000 are where lenders compete hardest. But dealer finance can be cheaper when a carmaker is offering 0% or low APR deals or a deposit contribution, so compare the APR and total amount payable for the same car.
What is the main difference between a car loan and car finance?
With a personal loan you borrow the money, buy the car and own it from day one; the loan is not secured on the car. With Hire Purchase or PCP the finance company owns the car until the last payment, and you get extra rights such as voluntary termination.
Can I hand the car back on a personal loan?
No. Voluntary termination only applies to Hire Purchase and conditional sale agreements, including most PCP. With a loan you would have to sell the car and use the money to pay off the loan, and make up any shortfall yourself.
What if the car is faulty?
On Hire Purchase or PCP, the finance company is legally the supplier, so your Consumer Rights Act claim is against them as well as the dealer. With a personal loan your claim is against the seller only. Paying part of the price on a credit card can add protection under section 75.
Does a car loan affect getting a mortgage?
Any monthly credit payment reduces how much a mortgage lender will offer, whether it is a personal loan or car finance. If you are planning to buy a home soon, keep the payment low or wait until after the mortgage completes.
