Details
Annuity (equal-payment) repayment keeps the monthly amount constant for the whole term. Each payment first covers the interest accrued on the remaining balance, with the rest reducing the principal — so early payments are interest-heavy and the principal share grows over time. The monthly payment follows the standard annuity formula: amount × monthly rate × (1 + monthly rate)^n ÷ ((1 + monthly rate)^n − 1).
This tool computes the monthly rate as the annual rate divided by 12 and rounds displayed amounts to whole currency units. Lenders handle rounding, daily accrual, fees and bonus-payment schedules differently, so real payments can differ from this estimate by a small amount. Compare numbers under the same rounding rules when evaluating offers.
Typical uses: estimating the monthly burden of a car or student loan, grasping the total interest and annual outlay of a long home loan, and weighing the interest savings of a shorter term or a refinance. The yearly balance column also shows when extra repayments bite the hardest. Results are estimates only — not a loan offer — and the definitive figures come from your lender's own simulation.
FAQ
What is annuity (equal-payment) repayment?
A repayment style where the monthly amount stays constant for the whole term. Early payments are mostly interest, and the principal share grows as the balance shrinks. It is the most common style for home and car loans.
Why does the result differ slightly from my lender's quote?
Lenders apply their own rounding, daily accrual, fees and bonus-payment schedules, so real payments can differ from this estimate by a small amount. Confirm exact figures with your lender's own simulation.
Can I calculate a 0% interest loan?
Yes. At 0%, the monthly payment is simply the amount divided by the number of payments, and total interest is zero.
Are the amounts I enter sent anywhere?
No. All computation happens locally in your browser and nothing you enter is transmitted.
