Car finance APR explained

APR is one of the key numbers to understand when you compare car finance deals. This page explains what APR is, how it affects your monthly payment and total cost, and how to use it alongside our calculators to make more informed decisions. It is general information, not financial advice.

What APR tells you

APR rolls together the interest rate on the finance and most compulsory charges into a single yearly percentage figure. This makes it easier to compare the cost of borrowing between different lenders and products. For a given amount and term, a lower APR usually means a lower total cost, although the shape of the payments (for example PCP vs HP) also matters.

Using APR with the calculators

When you use the car finance and affordability calculators on this site, you can plug in the APR you have seen in an advert or quote. By adjusting the APR up or down a few percentage points, you can see how sensitive your monthly payment and total repayable are to changes in rate. This will not match any specific lender's quote exactly but it can help you spot when a deal looks expensive for your circumstances.

Representative vs personal APR

Advertised car finance rates in the UK are often "representative"—the lender must offer that rate to at least 51% of successful applicants. The rest may get a higher rate or be declined. Your actual APR depends on your credit history, income and the lender's assessment. Use a range of APRs in our calculators (e.g. the advertised rate and a few points higher) to see how your payment and total cost could vary, and always get a personalised quote before committing.
