Car Finance Calculator UK — PCP & HP Payments

Last updated: April 2026

Car finance is the most common way to fund a vehicle purchase in the UK, with around 90 per cent of new cars bought on some form of finance agreement. Our car finance calculator helps you compare the monthly payments, total cost and interest charges across different finance types, deposit amounts and agreement lengths so you can find the best deal for your budget.

Whether you are considering a Personal Contract Purchase, Hire Purchase or personal loan, understanding the true cost of each option before you visit the dealership puts you in a stronger negotiating position. Enter your details below. For guidance on car finance and consumer credit, visit GOV.UK.

Understanding Car Finance Options

Personal Contract Purchase is the most popular car finance product in the UK. You pay a deposit, make fixed monthly payments over a set term, typically 24 to 48 months, and then choose whether to make a final balloon payment to own the car, hand it back or use any equity as a deposit on a new deal. Monthly payments are lower than Hire Purchase because you are not paying for the entire car, only the depreciation during the agreement period plus interest.

Hire Purchase is more straightforward. You pay a deposit and fixed monthly instalments, and once all payments are made you own the car outright. Monthly payments are higher than PCP but there is no large final payment. A personal bank loan is another option, giving you the advantage of owning the car from day one and being free to sell it at any time, though interest rates may be higher if your credit score is not strong.

What Affects Your Monthly Payments

The monthly cost of car finance depends on four main factors: the car price, your deposit, the interest rate (APR) and the length of the agreement. A larger deposit reduces both the monthly payment and the total interest you pay over the term. Longer agreements spread the cost but increase the total interest paid. Always compare deals using the APR rather than the flat rate, as APR gives a true representation of the annual borrowing cost including all fees and charges.

Your credit score significantly influences the interest rate you are offered. Borrowers with excellent credit can access rates as low as 3 to 5 per cent APR on dealer finance, while those with poor credit may pay 15 per cent or more. Checking your credit report before applying and correcting any errors can help you secure a better rate. Some manufacturers offer zero per cent finance on selected models, though these deals may come with a higher purchase price or restricted negotiation on the selling price.

Tips for Getting the Best Deal

Always negotiate the price of the car separately from the finance package. Get a pre-approved loan offer from your bank as a benchmark before visiting the dealer. Read the finance agreement carefully, including mileage limits on PCP deals and any charges for early termination. Remember that you have a 14-day cooling-off period after signing a finance agreement, during which you can cancel without penalty.
