// Amortization

Amortization is the process of paying off a loan over time through regular payments. Each payment covers interest first, with the remainder reducing the principal balance.

// Extra Payments

Adding even a small extra monthly payment can dramatically reduce your total interest and shorten the loan. Try entering $100–$500 above to see the difference.

// Interest vs Principal

Early in a loan, most of each payment goes to interest. Over time the ratio flips — by the end, nearly all of each payment goes to principal.

// Interactive Charts

Switch between balance curve, payment breakdown bars, and cumulative views to visualise exactly how your loan is repaid over time.
