Mortgage Calculator
Estimate your monthly mortgage payment, total interest, and how principal and interest split over the life of the loan.
How the payment is calculated
This uses the standard amortization formula for principal and interest: a fixed payment where the interest portion shrinks and the principal portion grows every month over the loan term, even though the total payment stays level.
What's missing from your real monthly payment
This estimates principal and interest only. A typical monthly housing payment (often abbreviated PITI) also includes property tax, homeowners insurance, and PMI if your down payment is under 20% — so your actual payment is usually higher than the number shown here.
