PCP, HP or a Loan: The True Cost of Car Finance

This article is general information, not financial advice. Consider your own circumstances or speak to a qualified adviser before acting on it.
Low monthly payments hide the real cost of car finance. Compare PCP, HP and loans on total cost, learn the hand-back rules and see when cheaper wins.
The true cost of car finance is everything you pay over the deal, minus what the car is worth to you at the end. Hire purchase and personal loans end with a car you own. A PCP keeps monthly payments low by deferring a large chunk of the price to a final balloon payment, so you can pay for years and still not own the car. Whichever you pick, compare deals on the total amount payable, keep the term short and choose the cheapest car you're happy to drive.
This guide is for anyone weighing a PCP against hire purchase, a personal loan or paying cash, or deciding whether a newer car is worth the extra.
PCP, HP and loans: what you're actually signing
The Financial Conduct Authority's review of motor finance describes PCP as a form of hire purchase with lower monthly repayments and a final balloon payment linked to the car's expected value at the end, known as the guaranteed minimum future value. At the end you can pay the balloon and keep the car, use any equity as part exchange on another car, or hand it back. Traditional HP, by contrast, spreads the car's value over equal payments with no significant balloon, so the car is yours once the final payment is made.
| PCP | Hire purchase | Personal loan | |
|---|---|---|---|
| Monthly payment | Lower, because part of the price is deferred | Higher, covers the full price | Depends on the rate you're offered |
| Who owns the car | The finance company, unless you pay the balloon | You, after the final payment | You, from the start |
| At the end | Pay the balloon, part exchange or hand back | Nothing more to pay | Nothing more to pay |
| Main risk | A balloon you can't afford, or a cycle of new deals | Higher payments | You must sell the car to get out early |
In the FCA's 2025 consumer research, some people hadn't fully considered downsides such as mileage limits or not owning the car at the end without an extra payment. Read the excess mileage rate and the fair wear and tear guide before you sign.
What the finance costs, in pounds
The site's car loan calculator models a standard fixed-rate loan with equal monthly payments. That fits a personal loan and is a close guide to HP, though any HP fees should be added. It does not model a PCP balloon, so use it to understand the finance cost, not to price a PCP quote.
Say you buy a £25,000 car with a £5,000 deposit, which is 20%, close to the average deposit in the FCA's research. You borrow £20,000 at 8.2%, the average rate current holders reported in that survey. The loan repayment calculator gives:
- 3 years: £628.57 a month, £2,629 interest
- 4 years: £490.14 a month, £3,527 interest
- 5 years: £407.44 a month, £4,447 interest
Stretching from three to five years lowers the payment by £221 a month and adds £1,818 in interest. On a PCP at the same rate and term, the interest bill is generally higher still, because the balloon part of the price stays borrowed until the very end and collects interest the whole time.
The FCA's research found that monthly payments being within budget was the most important factor for 68% of current motor finance holders, and many respondents couldn't recall the interest rate they were paying because they had focused on the payment. Average reported rates were 7.4% for new cars and 9.1% for used. Ask every dealer for the APR and the total amount payable, and compare those.
Getting out early costs more than people expect
Under section 99 of the Consumer Credit Act 1974 you can end a regulated hire purchase agreement, which includes PCP, before the final payment falls due. This is known as voluntary termination. Section 100 sets the price: unless your agreement asks for less, you must bring what you've paid up to half the total price, and pay extra if you haven't taken reasonable care of the car.
Here is the catch. On a PCP the balloon is part of the total price, so reaching the halfway point takes much longer than on HP. The voluntary termination right doesn't apply to a personal loan; to get out, you sell the car and repay the balance. After two years of a five-year £20,000 loan you still owe £12,964, which you can check month by month in the amortisation schedule calculator. If the car is worth less than that, you are paying to leave.
If you had car finance between 6 April 2007 and 1 November 2024, the FCA's car finance claims page explains when you may be owed compensation. The scheme has been legally challenged, with the case due to be heard in December 2026 or February 2027, so check the page for the current position and complain to your lender directly if you have concerns.
When the cheaper car wins, and when it doesn't
Compare the £20,000 borrowed above with a £10,000 loan for an older car at 9.1%, the average used-car rate in the FCA research. Over three years that costs £318.46 a month and £1,465 in interest. Against the £20,000 over four years, you pay about £172 a month less, around £2,060 less interest, and own the car a year sooner. That gap is money you could put into savings every month instead.
The honest downside is that an older car brings less predictable repair bills and may lack features you value. Keep a repair fund, and budget for insurance, servicing and MOTs on top of the finance.
The cheaper-car rule weakens in three cases:
- You genuinely want a new car every few years and drive predictable miles. A PCP can be a reasonable way to pay for use rather than ownership, as long as you accept you'll never own it without paying the balloon.
- A manufacturer is offering 0% or very low APR. The finance cost disappears, but compare the cash price with and without the finance offer.
- Paying cash would empty your emergency fund. A smaller loan with savings intact is safer than a paid-off car and nothing left for a repair.

Your next steps
- Next 10 minutes: run the amount you'd borrow through the car loan calculator at three, four and five years and note the total interest.
- Today: for any PCP quote, write down the balloon, the mileage limit, the excess mileage charge and the total amount payable.
- This week: get a personal loan quote from your bank to compare with the dealer's APR, and price a car two or three years older.
