How your mortgage payment is calculated

The standard fixed-rate mortgage payment (principal & interest) is:

M = P × [ r(1+r)ⁿ ] / [ (1+r)ⁿ − 1 ]

where P is the loan amount (home price minus down payment), r is the monthly interest rate (APR ÷ 12), and n is the total number of payments (years × 12).

Your total monthly payment adds the escrow items that lenders collect alongside P&I:

Property tax — home price × tax rate ÷ 12
Home insurance — annual premium ÷ 12
PMI — typically 0.3–1.5% of the loan amount per year, required when your down payment is below 20%
HOA fees — paid separately to your homeowners association

Note: Results are estimates for planning purposes. Actual lender quotes vary with credit score, points, and escrow analysis. Not financial advice.
