Free Loan Amortization Calculator

Ever wonder why your loan balance barely moves in the first year? That’s amortization: early payments are mostly interest, later ones mostly principal. This free calculator shows your monthly payment and a month-by-month schedule so you can see exactly where your money goes.

Fixed-rate, simplified

This schedule assumes a fixed interest rate, equal monthly payments, and no fees or early-payment penalties. Variable-rate or interest-only loans follow different patterns — but the core idea holds: more principal, sooner, always wins.
