Tips & Common Mistakes

Tips

  • Enter the loan amount as the total amount you plan to borrow, not the home price.
  • Use the current market interest rate for a more accurate estimate.
  • Remember that this payment does not include property taxes, homeowners insurance, or PMI.
  • Try different terms to see how they affect your monthly payment.

Common Mistakes to Avoid

  • Forgetting to convert the annual interest rate to a monthly rate – the calculator does this automatically, but ensure you enter the annual rate.
  • Including property taxes or insurance in the loan amount – this calculator only considers principal and interest.
  • Using the home price instead of the loan amount – if you make a down payment, use the amount financed.
