Disclaimer

This calculator is for estimation only. It is not financial advice and does not represent a lending decision. Your actual affordability and car finance options in the UK depend on your circumstances and the lender's criteria.

Used car finance in the UK

Finance for used cars in the UK works like a standard loan: you borrow the price minus your deposit and pay it back over a set term with interest. Lenders may offer different rates and terms for used cars, so use the calculator to compare scenarios and then get quotes.

Rates and terms for used cars

APRs for used car finance in the UK are often higher than for new cars, and some lenders cap the term or loan-to-value on older vehicles. Use a range of APRs in the calculator (e.g. 8% to 15%) to see how monthly payments and total cost change. If you are not sure what rate you might get, use our car affordability calculator first to set a monthly budget, then check how APR affects repayments.

Part-exchanging a used car in negative equity

If you still owe more on your current used car than it is worth, a lender may let you add that shortfall to finance on your next vehicle. That raises your monthly payment and total interest. Model the combined loan with our negative equity car finance calculator UK before you commit to a new used car deal.

Frequently asked questions

Can I use a car finance calculator for a used car in the UK?
Yes. Our used car finance calculator UK works the same way for new or used cars. You enter the price you are paying (or the car's value), your deposit, term and APR. The monthly payment is based on the amount you finance; UK lenders may offer different rates for used cars.
Is used car finance more expensive than new in the UK?
Often yes. UK lenders may charge higher APRs or shorter terms for used cars because of depreciation and risk. Use the calculator with a range of APRs to see how it affects your monthly payment for a used car.
What term can I get on used car finance in the UK?
Terms depend on the lender and the car's age and value. Many UK used car loans are 36–60 months. Enter different terms in the calculator to compare monthly payments and total interest.
Is this used car finance calculator free?
Yes. Our used car finance calculator UK is free. You enter the figures in your browser; we do not store your data. The result is an estimate only; get a quote from a UK lender before committing.
