Amortization

Calculation

Definition

The process of paying off a loan through regular payments over time. Each payment covers both principal and interest, with early payments weighted heavily toward interest.

Formula

Monthly Payment = P[r(1+r)^n]/[(1+r)^n-1] where P=principal, r=monthly rate, n=number of payments

Example

On a $500,000 30-year mortgage at 6.5%, your first payment might be $2,800 interest and $360 principal, while year 20 payments are more balanced.
