About This Calculator
This is a fast, no-frills version of a mortgage calculator that returns only your principal and interest (P&I) payment — useful when you already know your loan amount and don't need taxes or insurance factored in. For a full monthly payment including property tax, insurance, and HOA, use the full Mortgage Calculator instead.
How This Is Calculated
M = P [ i(1+i)^n ] / [ (1+i)^n − 1 ]
- M
- — Monthly principal & interest payment
- P
- — Loan amount
- i
- — Monthly interest rate (annual rate ÷ 12)
- n
- — Total number of payments (years × 12)
A $320,000 loan at 6.5% for 30 years has a monthly P&I payment of about $2,022.
Assumptions
- Fixed interest rate for the full term.
- Excludes taxes, insurance, HOA, and PMI.
