What is a mortgage calculator?
A mortgage calculator estimates the monthly cost of a home loan. It subtracts your down payment from the home price to get the loan amount, calculates the principal-and-interest payment, then adds property tax and home insurance to show your full monthly housing cost.
How it's calculated
Loan amount = home price − down payment. Principal & interest = loan × i × (1 + i)^n ÷ ((1 + i)^n − 1), where i is the monthly rate (annual rate ÷ 12 ÷ 100) and n is the number of months (years × 12). Total monthly = principal & interest + property tax ÷ 12 + insurance ÷ 12.
Example
A 400 000 home with 80 000 down (20%) at 6% over 30 years gives a loan of 320 000 and a principal-and-interest payment of about 1 918.56. Adding 4 000 a year in property tax and 1 200 a year in insurance brings the total monthly payment to about 2 351.90.
