You can use this calculator to answer such questions as:

  • How much mortgage can I afford?
  • What is the mortgage payment?
  • How much money do I need to buy a house?
  • What is the down payment on a house?

Related You may also like the Auto Loan Calculator. It also accepts six inputs, but it asks for an amount for the down payment rather than a percentage.

This Mortgage Calculator is not limited to solving mortgage loan problems of course. It can be a useful tool whenever money is borrowed to purchase an asset and the down payments is expressed as a percent.

  1. Your columns are mixed up.
    The interest and the principal columns are wrong which is causing numbers to be incorrect.

  2. You’re referencing the print preview? The numbers aren’t wrong there. Using the default example, click on calc and then print preview. I see the following number for interest and principal for the first payment.

    1,516.67 interest
    922.43 principal

    The loan amount is $280,000 @ 6.5% interest rate.

    (6.5 / 100 / 12) * 280,000 = 1516.667

    Also, check the last running total of the principal column, the total equals the loan amount i.e $280,000.

    Or were you talking about something else?

    • If you want to enter payments as they are made (to determine exact loan balance or to handle extra or missed payments) then you can use this Time Value of Money Calculator . (This is a more flexible calculator but it will take time to learn. Please scroll to the bottom of the page for 25 tutorials.)

      If you just want to specify the loan’s origination date and first payment date and have the other payments on a regular schedule then you can use this amortization table, which I see you have already found.
