Your mortgage payment includes principal, interest, mortgage insurance, real estate taxes, and homeowner’s insurance. The principal is the amount you borrow. The interest is the fee the bank charges. You can figure out the monthly amount by taking the annual interest rate (rate quoted) and dividing it by 12. Multiply that number (your monthly interest rate) by the outstanding principal balance to get your interest charges.

The mortgage payment is the principal (the portion you’ll pay) plus the monthly interest, 1/12th of the real estate taxes, 1/12th of the home insurance, and the required mortgage insurance (if applicable).
