Amortization Schedule

An amortization schedule shows how each loan payment splits between principal and interest, and how the balance shrinks over time. Early payments are mostly interest; later payments are mostly principal — even though the monthly amount stays the same.

Why generate a schedule?

• Plan prepayments. Knowing the exact interest portion of each payment helps you decide where extra money has the biggest impact.
• Refinance decisions. Compare remaining interest vs. closing costs of a refinance.
• Tax planning. In many countries, mortgage interest is deductible; the schedule tells you the deductible amount each year.

Extra payments

Set a fixed extra principal amount per month to see how dramatically the payoff date and total interest drop. Even a small extra payment in the first few years can shave years off the loan.
