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).
