What Is Included in Your Monthly Mortgage Payment?
Understand principal, interest, taxes, insurance and other housing costs so you can compare mortgage payments with realistic expectations.

A mortgage payment is easier to understand when you separate its parts. Whether you are buying again or entering homeownership for the first time, the principal-and-interest figure is only one part of the housing budget.
Separate the loan payment from the housing payment
Principal reduces the amount owed. Interest is the charge for borrowing. A basic mortgage calculator uses the loan amount, interest rate and term to estimate these two parts. Property taxes, homeowners insurance, mortgage insurance and association fees can make the total monthly housing cost higher. Check what a quoted figure includes before comparing it with another offer.
Work through a complete example
Imagine a fictional principal-and-interest payment of $1,800. Add $350 for property taxes, $150 for homeowners insurance and $100 for association dues. Those supplied figures total $2,400 a month. That is $600 more than the loan payment alone, before maintenance or utilities. The example is arithmetic, not a price estimate for a particular property or loan.
Build a budget you can revisit
Create separate lines for the loan, property bills and everyday ownership costs. Mark each number as confirmed or estimated and note who provided it. Replace assumptions with written figures as information becomes available. If you already own a home, build the new budget from the property you are considering instead of carrying over every cost from your current home.
