How This Calculator Works
An amortization schedule shows how each payment splits between principal and interest, and how the balance declines over time. Early payments are mostly interest; later payments are mostly principal.
Formula
M = P × [r(1+r)^n] / [(1+r)^n − 1]
Example
A $250,000 loan at 6.5% for 30 years costs $1,580/mo with about $318,000 in total interest.
Practical Use Cases
