An amortisation schedule shows you the full breakdown of every loan payment — how much goes towards interest and how much reduces the principal balance. In the early years of a loan, most of each payment is interest; as the balance reduces, more of each payment goes towards the principal. Our amortisation calculator generates a complete month-by-month schedule for any loan amount, interest rate, and term. This is particularly useful for mortgages, where understanding the amortisation schedule helps you see the impact of overpayments and plan your finances over the full loan term.
