About This Calculator
A mortgage calculator is an essential tool for anyone considering buying a home or refinancing an existing loan. It helps you estimate your monthly mortgage payment based on the home price, down payment, interest rate, loan term, and additional costs like property taxes, homeowners insurance, and PMI.
How It Works
The mortgage payment formula calculates your principal and interest payment using the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is the principal loan amount, r is the monthly interest rate, and n is the number of payments. The total monthly payment also includes property tax, insurance, PMI (if your down payment is less than 20%), and HOA fees.
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where: M = Monthly payment, P = Principal, r = Monthly interest rate, n = Number of payments
Key Benefits
- 1Understand exactly what your monthly housing costs will be before buying
- 2Compare different loan terms (15-year vs 30-year) side by side
- 3See how a larger down payment reduces your monthly payment and eliminates PMI
- 4Plan your budget with confidence using real numbers
- 5Identify the true cost of homeownership over the life of the loan
