Disclaimer

Quick answer: how this UK car finance calculator works
This calculator shows you a fixed monthly payment for your car finance in the UK. You enter the car price, your deposit, the term in months and the APR; we treat the price minus deposit as the finance amount and apply the standard loan repayment formula used for HP and many PCP agreements.
The result includes your monthly payment, the total interest you would pay over the term and the total repayable. Actual offers from UK lenders may include extra fees or different APRs, so always compare this estimate with real quotes before deciding.

How the calculator works
You enter the car price and your deposit; we use the difference as the finance amount. With the term (months) and APR you choose, we apply the standard loan repayment formula to get a fixed monthly payment. Total repayable is that payment times the term; total interest is total repayable minus the finance amount.
How loan term affects your payment
A longer term (e.g. 60 months) spreads the loan over more months, so the monthly payment is lower—but you pay interest for longer, so total interest is higher. A shorter term (e.g. 36 months) means higher monthly payments but less interest overall. Use the calculator to compare 36, 48 and 60 months for the same car price and APR so you can see the trade-off between monthly cost and total cost.
How APR affects the total cost
The APR (annual percentage rate) includes the interest rate and some fees, and it has a big impact on what you pay. A few percentage points difference can add hundreds or thousands to the total repayable over the term. Try different APRs in the calculator to see how they change the monthly payment and total interest. Your actual APR will depend on the lender and your credit profile; compare offers from multiple UK lenders or brokers.
Using this with the affordability calculator
If you know how much you can afford per month, use our car affordability calculator first to get a suggested monthly budget and maximum car price. Then use this finance calculator to see what monthly payment a specific car would cost at different deposits, terms and APRs. That way you can check whether the car you want fits within your budget before you apply.
