Your monthly payment is only half the story — the total is what you actually hand over. Figures are estimates; your real quote depends on the lender and your credit.
Your figures never leave your browser — we don't see or store them.
How we work this out
Monthly = (amount financed − balloon × discount factor) × monthly rate ÷ (1 − discount factor), where the discount factor is (1 + monthly rate)^−term. Total to own = deposit + payments + balloon. Total interest = total to own − car price.
The balloon is the Guaranteed Minimum Future Value (GMFV) — you only pay it if you keep the car. Lenders set it from predicted depreciation, mileage and term.
Full method: how we calculate.
PCP (Personal Contract Purchase) is car finance where your monthly payments cover the car's expected drop in value, with an optional final 'balloon' payment if you want to keep it. This calculator shows the monthly payment, the balloon and the total amount payable — so the low monthly doesn't hide the true cost of owning the car at the end.
PCP is the most common way to finance a new car in the UK precisely because the monthly looks small. That's because you're only paying off the depreciation, not the full price — the balloon, the car's predicted value at the end, is deferred. Pay it and the car is yours; walk away and it isn't.
What is PCP car finance?
PCP is a type of car finance where you pay for the car's depreciation, not its full price, and ownership is optional at the end. You put down a deposit, pay fixed monthly payments for 24–48 months, then choose to pay the balloon and keep the car, hand it back, or part-exchange.
Because you're only financing the drop in value rather than the whole price, the monthly payment is lower than HP for the same car. The trade-off is straightforward: you don't own the car unless you pay the balloon at the end, and you pay interest on that balloon for the whole term.
PCP is a regulated agreement under the Consumer Credit Act 1974, which gives you the right to settle early with an interest rebate and to hand the car back through voluntary termination once you've paid 50% of the total amount payable.
How does PCP work?
PCP runs in three stages: a deposit, fixed monthly payments over 24–48 months, then a choice at the end. The deposit and the balloon are set at the start; everything in between is the depreciation plus interest.
The balloon is fixed at the start by the lender, based on the car's predicted future value — driven by the model, the agreed annual mileage, and the term. Go over the mileage or hand back a damaged car and you'll pay excess charges.
- Deposit: usually around 10% — a £2,000 deposit on a £20,000 car. Some deals offer a zero-deposit entry, but that raises the monthly and the total interest.
- Monthly payments: fixed for the term, typically 24 to 48 months, covering the depreciation plus interest. A longer term lowers the monthly but raises the total interest.
- The choice at the end: pay the balloon (GMFV) to own the car, hand it back and walk away, or part-exchange any equity above the balloon into a new deal.
What is a balloon payment (GMFV)?
The balloon, or Guaranteed Minimum Future Value, is the lump sum you pay at the end of a PCP only if you choose to keep the car. The lender sets it at the start based on the car's predicted value, your mileage and the term.
It's called 'guaranteed' because whatever the car is actually worth at the end, that's the figure the lender will accept to let you own it. If the car is worth more than the balloon, you have positive equity to put towards a new deal. If it's worth less, you can simply hand it back and the lender takes the loss — that's the guarantee working in your favour.
Worked example
What happens at the end of a PCP?
You have three choices at the end of a PCP: keep the car by paying the balloon, hand it back and walk away, or part-exchange any equity. Each choice has different maths.
The 'walk away' option is the one most people undervalue. It's a form of insurance: if the used-car market tanks and the car is worth less than the balloon, you simply hand back the keys and the lender absorbs the shortfall. That protection is part of what the extra interest on PCP is paying for.
- Keep it: pay the balloon (often via a new loan or cash) and the car is yours — total cost = deposit + all monthly payments + balloon.
- Hand it back: return the car and walk away, owing nothing more — as long as it's within the mileage and condition terms. Excess mileage and damage are charged separately.
- Part-exchange: if the car is worth more than the balloon, the difference is equity you can put towards your next car — see selling on finance.
PCP vs HP: which is cheaper?
HP is usually cheaper overall; PCP keeps the monthly lower. The balloon is the single thing that makes the difference — you pay interest on it for the whole term.
That £1,400 gap is the price of the lower monthly and the flexibility to walk away. If you know you want to own the car at the end, HP usually wins; if you like changing cars every few years and value the walk-away option, PCP can be worth the premium. See the full breakdown in PCP vs HP vs leasing, or compare with HP directly.
| PCP (£8,000 balloon) | HP | |
|---|---|---|
| Monthly | ≈ £314 | ≈ £452 |
| Total to own | ≈ £25,086 | ≈ £23,695 |
| Total interest | ≈ £5,086 | ≈ £3,695 |
| Own it at the end? | Only if you pay the balloon | Yes, automatically |
| Mileage limit? | Yes | No |
Mileage limits and excess charges
Every PCP sets an agreed annual mileage, and going over it triggers an excess charge per mile at the end. That charge applies whether you keep the car or hand it back.
Typical limits are 8,000 to 12,000 miles a year, with excess charges from a few pence to over 20p per mile. Set the mileage realistically at the start — overestimating lowers the balloon and raises the monthly, but underestimating hands you a bill at the end. 5,000 miles over a 3-year deal at 15p a mile is £750.

Deposits, terms and the PCP maths
Three levers move the PCP monthly: the deposit, the term, and the balloon. Bigger deposit and longer term both lower the monthly; a bigger balloon lowers it more but raises the total interest.
Notice the pattern: every change that lowers the monthly raises the total to own. The balloon is the most powerful lever on the monthly but also the most expensive in total interest, because you're carrying that £8,000–£10,000 for the whole term.
| Change | Monthly | Total to own |
|---|---|---|
| Base (£2,000 deposit, £8,000 balloon) | ≈ £314 | ≈ £25,086 |
| Bigger deposit (£4,000) | ≈ £275 | ≈ £24,210 |
| Longer term (60 months) | ≈ £244 | ≈ £26,640 |
| Bigger balloon (£10,000) | ≈ £205 | ≈ £25,840 |
Thinking of ending a PCP early?
You can end a PCP early by settling it, or once you've paid 50% of the total amount payable, by voluntary termination. Both are rights under the Consumer Credit Act 1974.
Settling means paying the outstanding balance now, with a statutory rebate of the interest you haven't yet been charged — work it out with the settlement calculator. Voluntary termination lets you hand the car back once you've paid half the total amount payable (deposit + all monthly payments + balloon), owing nothing more, subject to mileage and condition. See voluntary termination for the detail.
Early in the deal you're often in negative equity — the car is worth less than the settlement figure — because PCP payments chip away at the balance slowly. That matters if you want to sell or part-exchange rather than settle or VT.
Were you mis-sold a PCP?
Some PCP deals taken out between 2007–2024 carried hidden commission that pushed up your interest rate. If yours did, you may be owed redress.
The FCA finalised a motor finance redress scheme (PS26/3) on 30 March 2026, following the Supreme Court ruling on commission disclosure of 1 August 2025. The scheme expects to return around £7.5 billion across roughly 12.1 million agreements, an average of about £829. You can estimate your position with the compensation estimator — every figure is an estimate, not a promise, and you can claim free yourself with no claims firm.
Is PCP right for you?
PCP suits drivers who want the lowest monthly, a new car every few years, and the option to walk away. HP suits those who want to own the car outright for the lowest total cost.
- Choose PCP if you value a low monthly, change cars every 3–4 years, and are comfortable with a mileage limit.
- Choose HP if you want to own the car outright, don't want a mileage limit, and want the lowest total cost.
- Choose a personal loan if you want to own from day one and sell whenever you like.
- Choose leasing if you never want to own and just want a fixed monthly budget.
