Amortization: balance, principal and interest by year

How is a mortgage payment calculated?

Principal and interest use the standard amortization formula: M = P × r(1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r the monthly rate and n the number of payments. Taxes, insurance, PMI and HOA are then added.

What is PITI?

  • Principal — repays the loan balance.
  • Interest — the lender's charge for borrowing.
  • Taxes — property taxes, usually collected in escrow.
  • Insurance — homeowners insurance (and flood insurance if required).

Frequently asked questions

This calculator adds estimated PMI (adjustable) when your down payment is below 20%. FHA loans use MIP instead — see our FHA calculator.
