This calculator uses the reducing-balance method that FCA-regulated lenders apply to PCP agreements. Interest builds on the full balance, including the balloon, across the whole term, while your monthly payments only reduce the non-balloon portion. Your real quote depends on the lender, any manufacturer subsidy and your credit profile.

Figures are illustrative only and not financial advice. Your actual APR and balloon depend on the lender and your circumstances. For your rights and how car finance is regulated, see the FCA guide to car finance.

How PCP car finance works

PCP stands for Personal Contract Purchase. It's the most popular way to finance a new car in the UK. Around 80% of new cars are now sold on some form of finance, and PCP makes up the majority of those deals. The reason it's so popular is simple: it keeps monthly payments low by deferring a large chunk of the cost to the end of the agreement.

Here's the basic structure. You pay a deposit, typically 10% of the car's price. Then you make fixed monthly payments for a set term, usually 36 or 48 months. At the end of the term there's a large balloon payment, also called the GMFV or Guaranteed Minimum Future Value. This balloon is the predicted value of the car when the agreement ends.

You're only paying interest on the difference between the car's price and the balloon, minus your deposit. That's why payments are lower than HP (hire purchase), where you pay off the entire cost.

The numbers: average PCP deal in 2026

The average new car in the UK now costs around £38,000. A typical PCP deal on a £25,000 car might look like this:

ElementAmount
Car price£25,000
Deposit (10%)£2,500
Amount financed£22,500
Balloon / GMFV (50%)£12,500
APR7.9%
Term48 months
Monthly payment≈ £326

Over 48 months you'll pay roughly £15,650 in monthly payments. Add your £2,500 deposit and you've spent about £18,150 before the balloon. If you want to keep the car, you'll pay the £12,500 balloon too, bringing the total to around £30,650 for a £25,000 car. That £5,650 difference is your interest cost. Change any input above and the figures update straight away.

Your three options at the end

When a PCP agreement ends, you have three choices:

  • Pay the balloon and own the car outright. Makes sense if the car is worth more than the balloon amount.
  • Hand the car back. Walk away with nothing to pay, as long as the car meets condition standards and you haven't gone over the mileage limit.
  • Part-exchange into a new PCP deal. If the car's market value beats the balloon, that equity becomes your deposit on the next car.

About 45% of PCP customers trade in for a new deal. Around 30% hand the car back. Only 25% pay the balloon and keep the car. Dealers like PCP because it brings customers back every 3 to 4 years.

APR: what you'll actually pay

Manufacturer-subsidised PCP deals can offer rates as low as 0% to 3.9% APR. These are loss-leaders to shift specific models. Non-subsidised rates from dealer finance typically run between 7% and 9% APR in 2026. If your credit score is below average, expect 12% to 18%. Rates move with the Bank of England base rate, so shop around when the base rate shifts.

For context, a personal loan from a bank for £20,000 over 4 years typically charges 5% to 7% APR. So if you can get approved for a personal loan, it's often cheaper than non-subsidised PCP. But you lose the flexibility of handing the car back.

Mileage limits and excess charges

Every PCP deal specifies an annual mileage allowance, typically 8,000, 10,000 or 12,000 miles per year. If you exceed it you'll pay an excess mileage charge at the end. This is usually between 5p and 10p per mile over the limit.

On a 4-year deal with a 10,000-mile annual limit, you're allowed 40,000 miles total. If you hand the car back at 52,000 miles, that's 12,000 miles over. At 8p per excess mile you'd owe £960. Some people get caught out badly here. The FCA has flagged excess mileage and end-of-contract charges as a common source of complaints.

What is GMFV and how is it set?

The Guaranteed Minimum Future Value (GMFV) is what the finance company guarantees your car will be worth at the end of the agreement. They set it conservatively based on projected depreciation, mileage and model. It's typically 40% to 55% of the original price for a 3-year deal, or 30% to 45% for a 4-year deal.

If the car's actual market value at the end is higher than the GMFV, you have positive equity. That equity becomes your deposit for the next car. If the market value is lower, which is rare because GMFVs are set conservatively, you can just hand the car back and the finance company absorbs the loss.

Negative equity: the hidden risk

During the PCP term, not at the end, you can end up in negative equity. This happens when you owe more on the finance than the car is currently worth. It's most common in the first 12 to 18 months of a deal, because new cars depreciate fastest in year one, typically 15% to 20%.

Negative equity becomes a problem if you want to change cars early or if the car is written off in an accident. Standard car insurance pays the market value of the car, not the finance balance. Gap insurance covers the difference and costs around £150 to £300 for the full term. For guidance on the cost of running a car, MoneyHelper is a good neutral source.

Common questions

PCP stands for Personal Contract Purchase. You pay a deposit, then fixed monthly payments across a set term, usually 36 or 48 months. A large balloon payment, the GMFV, sits at the end. You only pay down the gap between the car's price and that balloon, so monthly payments stay lower than hire purchase. At the end you can pay the balloon and keep the car, hand it back, or part-exchange into a new deal.
The balloon is the lump sum due at the end of a PCP deal if you want to own the car. It equals the Guaranteed Minimum Future Value, the amount the lender guarantees the car will be worth at the end. It's typically 40% to 55% of the price on a 3-year deal, or 30% to 45% on a 4-year deal. Interest is charged on the balloon across the whole term even though you don't pay it down monthly.
HP is usually cheaper in total if you keep the car, because you pay the whole balance down and stop carrying interest on the balloon. PCP has lower monthly payments but you pay interest on the balloon for the full term. On a £25,000 car at 7.9% APR over 48 months, PCP costs a few hundred pounds more in interest than HP once you settle the balloon. PCP wins on flexibility, HP wins on total cost.
You get three choices. Pay the balloon and own the car outright, which suits you if the car is worth more than the balloon. Hand the car back and owe nothing, as long as it's within the mileage limit and meets fair wear and tear. Or part-exchange, where any value above the balloon becomes the deposit on your next car. About 45% of drivers trade in, 30% hand back, and 25% pay the balloon.
Every PCP deal sets an annual mileage allowance, commonly 8,000, 10,000 or 12,000 miles a year. Go over it and you pay an excess charge when you hand the car back, usually 5p to 10p per mile. On a 4-year deal with a 10,000-mile limit you're allowed 40,000 miles total. Hand it back at 52,000 miles and, at 8p per excess mile, you'd owe £960. Check your real annual mileage before you pick a limit.
