Calculating costs in addition to principal and interest

The calculator lets you fine-tune your payment by entering your annual property tax premium, annual home insurance premium, monthly homeowner association (HOA) fee, and monthly private mortgage insurance (PMI) premium.
To enter this information, click “Show Advanced Info” underneath the main loan details. Note that you'll enter the annual cost for property taxes and home insurance and the monthly cost for HOA fees and PMI premiums. The PMI field will only display if your down payment is less than 20%.
In the “Loan Estimate” window, select "Amortization Schedule" to uncover a table that shows how much you'll pay in principal and interest each month, as well as the remaining amount you owe ("Principal balance") after making the payment.

Explanation of terminology

  • Total monthly payment: An estimate of all your monthly housing costs, covering your loan principal, interest, taxes, insurance, and PMI.
  • Total principal: This is the amount you borrow. Each mortgage payment reduces the principal you owe.
  • Total interest payments: How much interest you would pay over the life of the loan.
  • Total loan payments: The entire amount of principal and interest paid, excluding taxes, insurance, and PMI.
  • Down payment: The portion of the home’s price you pay in cash upfront. 
  • Interest rate: How much the lender charges you to lend you the money. Interest rates are expressed as an annual percentage. A lower interest rate gives you a smaller monthly payment.
  • Loan term (years): The number of years you have to repay the mortgage. A longer term gives you a lower monthly payment, but you’ll pay more interest.
  • Start date: The month that your first mortgage payment is due.
  • Payoff date: The month your home will be fully paid off based on the loan term.
  • Property taxes: The annual tax assessed by a government authority on your home and land. You pay about one-twelfth of your annual property tax bill with each mortgage payment, and the servicer saves them in an escrow account. When the taxes are due, the loan servicer pays them.
  • Homeowners insurance: Your policy covers damage and financial losses from fire, storms, theft, a tree falling on your house and other bad things. As with property taxes, you pay roughly one-twelfth of your annual homeowners insurance premium each month, and the servicer pays the bill when it's due.
  • Monthly HOA fees: The amount you may pay each month if you belong to a homeowners association. Typically, these dues are billed directly, not added to the monthly mortgage payment. Because HOA dues can be easy to forget when considering the cost of homeownership, NerdWallet's mortgage calculator allows you to enter them here.
  • Private mortgage insurance: If you get a conventional mortgage and put down less than 20%, you’ll have to pay a monthly PMI premium. It covers the lender if you default on the loan and can be canceled once you reach 20% equity. FHA loans require a similar fee called a mortgage insurance premium.
