What Is PITI?

PITI stands for principal, interest, taxes, and insurance — the four parts that commonly make up a monthly mortgage payment. Principal and interest repay the loan; property taxes and homeowners insurance are often collected monthly through an escrow account. Lenders use PITI when calculating housing-related debt ratios.

Formula

PITI = monthly principal and interest + (annual property tax ÷ 12) + (annual homeowners insurance ÷ 12). Mortgage insurance and HOA dues are sometimes added, as PITIA or PITI + HOA.
