About this calculator

Shows principal & interest (P&I) only. Your actual payment will also include property taxes, homeowners insurance, and possibly PMI if your down payment is under 20%.

Try adding an extra monthly payment to see how much interest you can save and how many years you can shave off your loan.

Core Numbers
Total purchase price of the home.
The upfront cash amount you pay.
Your annual mortgage interest rate.
Mortgage length: typically 15 or 30 years.
Additional principal paid each month.
Rows to show in the schedule.

How to read the table

  • Annual Payment is the total P&I paid in that calendar year.
  • Principal is how much the loan balance shrank — this is real equity building.
  • Interest is the cost of borrowing that year. It falls over time as the balance drops.
  • Cum. Interest is the running total of interest paid since month one.
  • Balance is what you still owe. Sell above this to walk away with equity.
  • Equity % shows what fraction of the original loan amount you've paid down.
Note: P&I only. Does not include taxes, insurance, PMI, or HOA. Contact your lender for a full PITI estimate.
