See how much time and interest you save by adding a fixed extra amount to your monthly loan payment.
This simulates your loan balance month by month: interest accrues, then your payment (plus any extra) is applied to principal, until the balance reaches zero.
This is a pure amortization simulation from the numbers you enter — no country-specific loan rules or currency assumptions are built in, so it works for any mortgage, auto loan, or personal loan. Not financial advice.
