How this mortgage calculator works
This free mortgage calculator estimates your monthly payment using the standard amortization formula. Enter the home price, your down payment, the loan term and the interest rate, and it instantly shows your principal and interest — plus property tax and insurance for a true “PITI” monthly payment.
Your loan amount is the home price minus your down payment. A bigger down payment lowers both your monthly payment and the total interest you pay over the life of the loan.
What is included in a monthly mortgage payment?
Most payments have four parts, often called PITI: principal (paying down the loan), interest (the cost of borrowing), taxes (property tax) and insurance (homeowner’s, and PMI if your down payment is under 20%). This calculator covers principal, interest, tax and insurance.
How much does the interest rate matter?
A lot. On a 30-year loan, even a 1% higher rate can add tens of thousands of dollars in total interest. Try a few rates above to see the impact on your total cost.
Running the numbers on a rental or flip?
A mortgage payment is only half the story for investors. The Real Estate Investor Toolkit adds cash flow, cap rate, BRRRR and fix-and-flip analysis, and the Closing Cost Calculator covers your upfront costs.
