About This Tool

What it does

Calculates monthly car loan payments using the standard amortisation formula. Shows monthly payment, total amount paid and total interest charged over the loan term. Enter the loan amount (vehicle price minus any deposit) for a result consistent with this model.

Who it's for

Anyone comparing a conventional fixed-rate vehicle loan or hire-purchase style agreement with no balloon payment. PCP, leases and agreements with a final optional payment require a separate calculation.

Your privacy

All calculations happen in your browser. No financial data is transmitted or stored anywhere.

What the auto-loan result includes

The estimate uses equal end-of-month payments and a monthly rate equal to the entered annual rate divided by 12. A larger deposit reduces the amount financed, while a longer term normally lowers the payment but increases total interest.

Compare the full cost, not only the payment

Two offers can have a similar monthly payment but different deposits, fees, balloon payments or terms. Compare the lender’s disclosed total amount payable. This calculator excludes fees, taxes, insurance and any balloon or final optional payment.

Before committing

Check early-settlement and excess-mileage terms.

Frequently Asked Questions

How is the monthly vehicle-loan payment estimated?

Enter the amount financed, annual rate and number of monthly payments. The calculator assumes a fixed rate, equal end-of-month payments and no fees or balloon payment. It shows the regular payment, total repaid and total interest.

Can I use this for PCP or balloon finance?

Not directly. PCP and other balloon arrangements leave a large final payment, so their regular payments are not the same as a fully amortising loan. This calculator can approximate hire purchase only when the entered amount is fully repaid by the selected monthly payments.

What rate should I enter?

Use the fixed annual borrowing rate stated for the agreement. An advertised APR may include mandatory fees and can differ from the rate used to accrue interest, so compare this estimate with the lender’s disclosed monthly payment, finance charge and total amount payable.
