Loan amortization schedule and prepayment impact calculator. Simulates extra monthly and annual principal prepayments, measuring tenure reduction and thousands saved in compound interest.
Runs entirely in your browser
An amortization schedule lays out every payment over a loan’s life, splitting each into interest and principal and tracking the falling balance. This tool generates that schedule and, crucially, models the effect of extra prepayments — additional monthly or annual amounts paid toward the principal — showing how much they shorten the term and how much interest they save.
Prepayments are one of the most powerful levers a borrower has, and their effect is larger than intuition suggests: because early payments are mostly interest, paying down principal early removes years of future interest. Seeing the tenure reduction and interest saved side by side makes a compelling, concrete case for even small extra payments.
It runs in your browser, so your loan details stay private. Use it to plan a payoff strategy, compare the impact of different extra-payment amounts, or decide whether prepaying beats investing the same money elsewhere.
