Mortgage Calculator Online — Free Tool
Generate a complete mortgage amortization schedule, including monthly payments, total principal paid, and total interest accrued.
Mortgage Calculator
Estimates monthly payment for a fixed-rate mortgage (principal + interest only).
About this tool
A mortgage payment usually combines principal, interest, taxes, and insurance (PITI). This calculator estimates monthly payment from loan amount, annual interest rate, and term in years, using standard amortization math.
You can see how a lower rate or shorter term raises the monthly payment but reduces total interest paid over the life of the loan. Use it when comparing offers from lenders or deciding how much home fits your budget.
Common use cases
- Budgeting monthly housing costs before you apply
- Seeing total interest paid over 15- vs 30-year terms
