Generate a full payment schedule showing every principal & interest split
Loan amortization is the process of spreading loan payments over time so that each payment covers both interest and a portion of the principal. Early payments are interest-heavy; later payments shift toward principal as the balance declines.

Formula
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1]P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Total number of monthly payments
Worked Example
$200,000 loan at 6.5% for 30 years
Did you know? On a 30-year mortgage at 6.5%, you pay more in total interest than the original loan amount. The Consumer Financial Protection Bureau estimates homeowners can save tens of thousands by refinancing when rates drop even 1% (source: CFPB Mortgage Resources).
