How a fixed-rate amortization works
This calculator uses the standard fixed-payment formula:
PMT = P · (i·(1+i)n) / ((1+i)n − 1)
Each monthly payment is split into interest (which depends on the remaining balance) and principal (what actually pays down the debt). In the early years, most of your payment goes to interest. Over time, the share of principal grows.
Tips before signing a loan
- Compare APR, not just the rate. APR includes fees and gives a better picture of cost.
- Shorter term ≠ always better. Higher payments may strain your monthly budget.
- Extra principal payments early save much more interest than late ones.
