An auto loan calculator helps you find out the monthly payment, total interest and full cost of a car loan in advance. It works for financing a new or used car at any bank or dealership — the calculation is not tied to a particular lender.
Enter the car price and the down payment — in money or as a percentage of the price. Set the term in months and the interest rate (your bank or dealer quotes it at pre-approval). Choose the payment type — annuity or differentiated — and the calculator instantly shows the monthly payment, interest overpayment and a full month-by-month payment schedule.
With an annuity payment the monthly amount stays the same for the whole term: at first you mostly pay interest, towards the end — the principal. With a differentiated payment the principal is repaid in equal parts, so the payment decreases every month and the total interest is usually lower — but the first payments are noticeably higher.
The calculator supports several early repayments, each with a month and an amount. You can choose the recalculation method: reduce the payment (same term, lighter load) or reduce the term (same payment, the loan ends sooner). The latter is usually more beneficial: less interest accrues. The payment schedule shows how the payment changes after each early repayment.
Some dealers offer balloon-payment (buy-back) plans: the loan is split into two parts. The first part is repaid with regular payments over 2–3 years; the second part (usually 20–40% of the car price) is due as a single final payment — or the car is handed back to the dealer to settle the debt. The monthly payment is much lower, but the rate is higher and the car stays encumbered for the whole term. Before calculating, subtract the balloon amount from the loan amount.
Until the loan is repaid, the car is collateral for the bank, so the lender almost always requires full coverage insurance (comprehensive plus collision). The premium depends on the make and model, the driver’s age and record, the region and the deductible; it is usually 3–8% of the car price per year. Factor this into your budget — the calculator shows the loan payments themselves.
The monthly payment is calculated as A = P × r / (1 − (1 + r)−n), where P is the loan amount, r is the monthly rate (annual / 12) and n is the term in months. For example, a loan of 2,000,000 at 15% per annum for 5 years: payment ≈ 47,580, overpayment ≈ 854,792.
The calculation is preliminary. Check the exact terms with your bank.
