The loan calculator is one of our most popular financial calculators. It can solve for one of four unknown values, or you can enter values for loan amount, term, interest rate and payment and it will create a schedule using your values. More below...»

Will making small, extra payments save me money?
Our Extra Payment Calculator will create an amortization table and show you the interest saved.
Will paying half the monthly payment every other week save interest charges?
Check out our Biweekly Loan Calculator to find out.
Enter a "0" (zero) for one unknown value above.

About dates - if you want to create a schedule that accurately reflects a loan's origination date (the day the money is borrowed) and the first payment date followed by regularly scheduled payments, then use our amortization schedule.

Don't over pay, don't under collect. If you need to track payments on the exact date they are paid (or missed) for whatever amount, then use our Ultimate Financial Calculator.

Since the calculator will solve for multiple unknowns, it can easily be used to answer the following questions:

  • How much can I borrow?
  • What would my payment be?
  • What is the lending rate?
  • How long will it take to pay off my loan?
  • What date is my loan paid off?

On a more general note, we have been discussing details about loans, some structured with unusual details, over several decades. At this point, we believe our software calculators can create a schedule for any custom loan that exists. If you have a loan with unusual terms, please ask.

Hopefully you'll find this loan calculator as well as all the financial calculators on this site to be useful tools. Why not take another sip of your favorite beverage and explore for a few minutes?

    • It’s not likely, at least not for a good while. First, I don’t know how to program for iOS. But secondly, what would an iOS version offer that the web calculator doesn’t? I use this calculator on my iPhone 5 regularly. I can even print to a wireless inkjet without a problem from the iPhone.
