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.

What is amortization? According to vocabulary.com, "amortization means a debt is being paid off by a series of payments".

  1. I am an accountant using it personally to aid others in their loan decisions. Great schedule. I like the year-end summaries. One thing I would update: when changing the parameters and then clicking on “calc”, it does not update. The original data needs to be cleared first then start over and all is well – amount recalculated correctly.

    When doing “what ifs” it would be nice to just change the % – for example and not have to re-enter the amount and time period for the loan.

    Thanks, well done

    • Thank you for your comment. I always appreciate hearing how people use a calculator as well as getting suggestions.

      At one time, some of the calculators did work the way you suggest but having them recalculate the prior unknown automatically limits their usefulness. The present design now supports negative amortization, for example. Also, a borrower can pay what they want (as long as the lender agrees of course) and the calculator will create a schedule with the correct periodic interest amount.

      One thing has me confused though. You should be able to do what-ifs by changing the rate and then resetting another value to 0 for it to be calculated. You should not have to reenter any other value. If it does not behave that way for you, please give me the details.

    • Mary, if you don’t blank 1 parameter, you aren’t asking it to calculate anything. You can choose whichever parameter you wish for the calculator to tell you. Karl, that is a wonderful feature. Change one, blank one, and it can tell me anything.

  2. After searching for an amortization schedule that is clean and structured well enough to include in presentations, this is it! Nice work and saved this site for future needs. Thanks!

  3. This is the best amortization calculator that I have found. We have a note with no term specified, a fixed monthly payment and interest rate. All other calculators need a fixed term to produce an amortization table. Thank you.

  4. As a tax preparer, I often have to come up with an amortization schedule for auto loans, rental property loans, shareholder loans, etc. Your calculator is JUST PERFECT! Thanks for all of your hard work in developing this calculator.

  5. I had a client choose to pay a rounded number, monthly, instead of the amortized payment rate. Your program quickly and painlessly computed the new adjusted principal balance. Thanks!

  6. My first use of your website amort schedule calculator. Looks very good. I always want yearly totals and not all schedules include this. Thank you. I will be back when needed. I am a sole-practitioner attorney needing schedules infrequently.

  7. hello. i’m a new user here. just used the amortization calculator for the first time. i’m not sure how i got to this website but i was trying other calculators and i wasn’t getting what i needed. i needed to see what my balance should be on a 30 year fixed second mortgage. i was convinced my payments were not being handled properly. the other calculators i tried would give me a schedule but they wouldn’t let me go back and enter the date when my loan began which was in 2007. so, finding this one was great and being able to enter a first payment date in 2007 really helped me. it showed me that my mortgage company is doing a better job than i thought they were of applying my payments because the balance they gave me today over the phone was within a few dollars of what this calculator told me it should be. so thanks to the creator of this site. you reduced my stress level by a lot making this calculator available. i think people’s lives would be a lot better if they understood the concepts that can be learned by using tools like this website.

    • Thank you for letting me know this. Glad to hear this calculator relieved some stress. Hope to "see" you back again.

  8. Love the Amortization Schedule Calculator! I looked all over the web for something useful and struggled with Excel a bit without much luck, so thanks for creating an easy to use tool.

    I used it for personal use, as we’re planning to sell our house and buy a new one and I was able to easily calculate our current loan balance and the monthly payments on a new house. Thanks again!

  9. I am glade to have this web site only one improvement , if some body can make, there should be option for year end to calculate total interest for the year, presently it calculate for Dec 31 year ends, some time corporation has year end different than Dec 31 in this case we have to calculate interest manually

    • Perhaps I will add that feature to the online calculators one day. In the meantime, if you are running Windows, you may want to consider purchasing either C-Value! or SolveIT!. They both can create amortization schedules that allow the user to select a different month other than December for year end.
