How the monthly payment is estimated
This calculator shows 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 personal loan agreements. For APR context see car finance APR explained.
