Important Note About Dates: This calculator allows irregular length first periods. That is, the calculator calculates the exact amount of interest due even when the initial period is shorter or longer than the other scheduled periods. This will produce interest charges that do not match other calculators. If you want to match other calculators then set the "Loan Date" and "1st Payment Date" so that they equal one full period as set in "Payment Frequency". Example: If the "Loan Date" is May 15th and the "Payment Frequency" is "Monthly", then the "1st Payment Date" should be set to June 15th, that is IF you want a conventional interest calculation. See the end of the "Help" text for some more details.

Don't want to be bothered setting dates? No problem. Use this loan calculator. It also creates an amortization schedule.

  1. Hi Kari,

    I am trying to run a quarterly payment loan that will end up with a balloon. The schedule keeps including a huge payment on the first payment date in order to fully amortize the loan. Not what I want. How do I get the program to apply the payments equally to all installments?

    Here are the details:
    Loan Amount: $1,200,000
    Interest Rate: 5.50%
    Loan Date: 1/28/2010
    First Pmt : 4/1/2010
    Payments: 27
    Payment Amount: $22,140.00
    Compounding: Monthly
    Amortization Method: Normal


    • Hi Rick, this is not the calculator that you want to use. Instead, please see the Time Value of Money Calcultor. It will give you full control over all details. If you scroll down the page, there are 25 tutorials – 2 of them dealing specifically with balloon loan options:

      7. Balloon Payment Calculation
      Calculate the balloon amount

      8. Balloon Loan Calculation
      Calculate the periodic payment required to result in a specified balloon

      Also, under the Setting button, there are options for how you want the initial period’s interest handled.

      Once you check it out, if you have any questions, you can ask them in the comments area under that calculator.
