🚗 UK monthly payment planner

Car Finance Calculator (UK)

Estimate monthly repayments, total interest and full ownership cost before you agree to a car finance deal. Switch between HP and PCP, add a deposit or trade-in and include a final balloon payment if the quote uses one.

Most UK quotes use a representative APR, but your exact rate can change with credit profile, age of vehicle, mileage and lender criteria. PCP deals usually show a Guaranteed Minimum Future Value or balloon amount due if you want to keep the car at the end.

This calculator works out the financed amount after deposit, trade-in and fees, then applies a monthly APR formula across the selected term. PCP adds an optional final balloon payment to reduce monthly instalments.

How the car finance calculation works

The calculator starts with the vehicle price, subtracts your cash deposit and any trade-in equity, then adds fees to get the amount being financed. Monthly interest uses the quoted APR divided by 12. For PCP deals, the final balloon payment is discounted back across the term, which lowers the regular monthly repayment compared with HP.

  • HP is usually simpler: higher monthly payments, no large final purchase fee beyond any lender option charge.
  • PCP usually gives lower monthly payments but a larger final sum if you want to keep the car.
  • Total interest matters more than the monthly payment alone when comparing offers.

Before you sign a UK finance deal

Check whether the quote includes a document fee, option-to-purchase fee or mileage restrictions. A lower monthly payment can still cost more overall if the APR is high or the final balloon amount is large.

This is a planning tool, not regulated financial advice. Always compare the lender's pre-contract information and full repayment schedule before agreeing to finance.
