Calculateur de Prêt Gratuit en Ligne

Both use the same amortization formula, but personal and auto loans typically have shorter terms (1–7 years) and higher interest rates than mortgages. The mortgage calculator here defaults to home-purchase scenarios; the loan calculator is sized for personal, auto, and short-term borrowing.

Enter the car's purchase price minus your down payment as the Loan Amount. Enter the dealer's APR as the Annual Interest Rate, and set the term to 48, 60, or 72 months (4, 5, or 6 years). The monthly payment shown reflects principal and interest only — add insurance and tax separately.

Even a 1% difference in rate on a $20,000 loan over 5 years adds roughly $500–$600 in total interest paid. Over longer terms, the compounding effect is larger. Use the calculator to compare two rate scenarios side-by-side by running each calculation and noting the total interest figures.

Yes. Enter the outstanding balance as Loan Amount, your loan's interest rate, and the standard repayment term (typically 10 years for federal loans). For income-driven repayment plans, your actual payment is based on income, not a fixed amortization — this calculator shows the standard schedule.

Making even one extra payment per year significantly reduces total interest and shortens the loan term. This calculator shows the standard fixed-payment schedule. To model prepayments, reduce the Loan Term by the number of months you expect to pay early, or reduce the principal by the lump sum.
