Use this car finance calculator to estimate your monthly repayments, total interest, and total amount payable when financing a vehicle in the UK. Enter the car price, deposit, annual percentage rate (APR), and repayment term. You can also enter an optional final balloon payment to explore how a larger payment at the end affects your regular monthly instalments.
How to Use the Car Finance Calculator
Enter the vehicle’s purchase price and the deposit you plan to pay upfront. Add the annual interest rate and select your intended finance term in years. If your agreement includes a final balloon payment, enter that amount in the optional field.
The calculator estimates your monthly payment and total cost using these figures. Change the inputs to compare different deposits, rates, and repayment periods.
Understand Monthly Repayments and Total Interest
Your monthly repayment depends on the amount financed, the interest rate, and the term. A larger deposit generally reduces the amount borrowed, while a longer term can reduce monthly payments but increase the total interest paid.
Review both your monthly instalment and total payable when comparing finance offers, rather than choosing a deal based on the monthly figure alone.
How a Balloon Payment Affects Car Finance
A balloon payment is a larger amount due at the end of certain finance agreements. Including one in the calculation reduces the balance covered by regular instalments, which can lower the estimated monthly payment.
However, you still need to account for the final payment when assessing the overall cost. PCP agreements can also have mileage conditions, vehicle-condition requirements, and other contractual terms that this calculator does not model.
Check Your Car Finance Budget Before Committing
Compare the estimated repayment with your monthly income and other financial commitments before deciding what you can afford. Remember to budget for insurance, fuel, vehicle tax, servicing, repairs, and other running costs.
The calculator provides an estimate based on the information entered; a lender’s actual quote may differ because of fees, payment timing, credit assessment, and the specific finance agreement.
