How it's calculated
Payment = P × i ÷ (1 − (1 + i)^−n) Each month: interest = balance × i; principal = payment − interest; balance −= principal
An amortization schedule shows how a fixed payment pays interest first and principal second; the share going to principal grows every month. Extra payments come straight off the principal, which shortens the loan and cuts the total interest.
