A repayment mortgage (also called an amortized or annuity loan) is paid back in equal monthly instalments. Each instalment covers the interest due that month plus a slice of the outstanding balance. Early on, most of the payment is interest; as the balance shrinks, more of each payment goes to principal. By the final month the loan is fully repaid.
The monthly payment is fixed by three numbers: the amount borrowed, the monthly interest rate (the annual rate divided by twelve) and the number of monthly payments (the term in years times twelve). This calculator uses the standard formula payment = P × r / (1 − (1 + r)−n), the same maths used by banks across the eurozone and the United States.
Stretching a loan from 20 to 30 years lowers the monthly payment but sharply increases the total interest, because you owe money for longer. A shorter term costs more each month but far less overall. Use the compare feature to see both side by side before you commit.
Adding even a small fixed amount to each payment goes straight to the principal, which shortens the loan and compounds into large interest savings. Enter a figure in the “extra monthly payment” field to see your new payoff date and the exact interest you would avoid.
It shows the pure loan repayment. It does not add property tax, buildings or mortgage insurance, notary or arrangement fees, or account for a variable rate changing over time. Treat the result as a clean baseline and add local costs separately.

Put a bank’s rate and term against another lender’s in the two-scenario view to find the genuinely cheaper deal.
Compare your current mortgage with a new rate to decide whether switching is worth the paperwork.
The same maths works for any fixed-rate instalment loan — set the amount, rate and term in months-as-years.
See how an extra €100 or $200 a month shortens the loan and how much interest it saves.

It uses the standard amortized loan formula (annuity / French system): payment = P × r / (1 − (1 + r)−n), where P is the loan amount, r is the monthly interest rate and n is the number of monthly payments.
Yes. The amortization maths is identical worldwide. You choose euros or dollars, set your own rate and term, and the calculator produces the payment and schedule. It does not add country-specific taxes or insurance.
No. Every calculation runs inside your browser. Nothing you type is uploaded, stored on a server or shared with anyone.
Yes. Enter an optional extra monthly amount and the calculator shows the new payoff date and the total interest saved compared with the original schedule.
Interest is charged on the outstanding balance, which is highest at the start. As you repay principal, the interest portion of each payment falls and the principal portion grows.
Yes. With a 0% rate the payment is simply the amount divided by the number of months.
No. The results are estimates for planning only and exclude fees, taxes, insurance and rate changes. Always confirm figures with your lender.
