Amortization Schedule
  • Create printable amortization schedules with due dates
  • Calculate loan payment amount or other unknowns
  • Supports 9 types of amortization.
  • User can set loan date and first payment date independently.
  1. Leave all inputs and setting set to their defaults, and:
    • Enter the "Loan Amount."
    • Enter the expected "Number of Payments."
    • Enter the anticipated "Annual Interest Rate."
  2. Set "Payment Amount" to "0."
    (the unknown)
  3. Click either "Calc" or "Print Preview".

That's it! That's all you need to do to create your schedule quickly.

But what if the terms of your loan do not conform to this calculator's default settings?

Then keep reading. I'll explain all the options below. More

Always enter (and reenter) a 0 for the unknown value.

Cheat Sheet

Note - You must enter a zero if you want a value calculated.


Because we want this calculator to create a payment schedule using the loan terms you need. The payment amount can be whatever you want it to be. A payment is "correct" as long as both the lender and debtor agree on the amount! (If the calculator always recalculated the last unknown, then this feature would not be possible.)

TIP - Use an amortization schedule to confirm the periodic interest charges. Interest amounts are the calculations that borrowers should be validating.

Four values you will always need to set:

  • Loan Amount - the amount borrowed, i.e., the principal amount. It does not include interest.
  • Number of Payments (term) - the length of the loan. The "Payment Frequency" setting also impacts the loan's term. For a term of fifteen years, if the payment frequency is biweekly, you need to enter 390 for the number of payments. (390 biweekly payments = 15 years)
  • Annual Interest Rate - the nominal interest rate. This the quoted interest rate for the loan.
  • Payment Amount - the amount that is due on each payment due date. For "normal amortization," this includes principal and interest.

Set one of the above to 0 if unknown.

  • How do I calculate how much I can borrow?
    1. set the loan amount to zero
    2. enter the number of payments
    3. enter the annual interest rate, and
    4. enter the expected or desired payment
    5. click "Calc" or "Print Preview"
  • How do I calculate how long it will take to pay off a loan?
    1. enter the loan amount
    2. set the number of payments to zero
    3. enter the annual interest rate, and
    4. enter the expected or desired payment
    5. click "Calc" or "Print Preview"
  • What interest rate allows me to pay $500 a month?
    1. enter the loan amount
    2. enter the number of payments
    3. set the annual interest rate to zero, and
    4. enter $500 for the payment amount
    5. click "Calc" or "Print Preview"

About Dates - they may be (or may not be) important (to you):

If you want an estimated schedule, you may skip over this section.

If you want an accurate, to the penny amortization schedule, you should spend a minute or two understanding these options.

  • Loan Date - the date the money is available. If the loan is for a vehicle or home, it is also known as the loan's closing date, start date, or origination date.
  • First Payment Due - for leases, it may be the same as the loan date; otherwise, payments will usually start sometime after the borrower has had access to the loan proceeds.

Important - Selecting dates will result in interest charges as well as payment calculations that do not match other calculators.

And that's the point!

However, if you want to match other calculators, then set the "Loan Date" and "First Payment Due" so that the time between them equals one full period as set by "Payment Frequency."

Example: If April 10th is the "Loan Date" and the "Payment Frequency" is "Monthly," then set the "First Payment Due" to May 10th, that is if you want an estimated interest calculation.

More details about the settings available for odd day and irregular period interest.

Four loan options you most likely don't need to touch.

  • Payment Period or Frequency - how often do you want to schedule payments? The calculator supports 11 options, including biweekly, monthly, and semiannual (useful for bond coupon interest schedules). The schedule calculates the payment dates from the first payment due date (not the loan date).
  • Compounding Period or Frequency - usually, the compounding frequency should be set to the same setting as the payment frequency. Doing so results in simple, periodic interest. Setting this option to "Exact/Simple" results in simple, exact day interest.
  • Points - one point is one percent of the loan amount. Points are generally applicable to U.S. mortgages. More about loan schedules with points, fees, and APR support.
  • Amortization Method - leave this setting set to "normal" unless you have a specific reason for setting it otherwise. For a complete explanation of these options, see Nine Loan Amortization Methods.

Five loan options you may want to tweak.

These options are available by clicking on "Settings."

  • 360 / 365 / 366 - days-per-year option. This setting impacts interest calculations when you set compounding frequency to a day based frequency (daily, exact/simple or continuous) or when there are odd days caused by an initial irregular length period. The 366 days in year option applies to leap years, otherwise the interest calculation uses 365 days.
  • Long/Short Period Options - settings for how interest is shown on the schedule when the initial payment period (the time between the loan date and first payment date) is longer or shorter than the selected payment frequency. Click for more details and examples.
  • Last Period Rounding Options - due to payment and interest rounding each pay period (for example, payment or interest might calculate to 345.0457, but a schedule will round the value to 345.05), almost all loan schedules need a final rounding adjustment to bring the balance to "0". A footnote on the payment schedule informs you of the rounding amount.
  • Points, Charges, & APR Options - see loan schedules with points, fees, and APR support.
  • Year-End Month - this setting establishes after what month the calculator shows year-end and running totals. This option is to accommodate businesses with fiscal year ends that do not coincide with the calendar year-end.

Printing the Payment Schedule

Printing will work from any type of device. It's pretty cool to print a well-formatted schedule from a smartphone that is connected wirelessly to a modern printer. (I've personally tested this using various iPhones printing to an HP LaserJet Pro printer.)

Make sure you are printing from the "Print Preview..." window where there are two print buttons available.

If you are using a modern browser, you can print to a PDF as well. For example, if you are using Chrome, click on the menu (the three verticle dots) and select "Print..." Click on the "Change..." button and select "Save as PDF." Other browsers will work similarly.

If you have any problems, please let me know what browser and version you are using. I can test various browsers, but unfortunately, I can't check too many printers (unless you plan to donate one to the cause!).

Beyond Basic Amortization Schedules

Hopefully, you'll find this to be a full-featured amortization schedule calculator. If there's something you need, and it's not clear how to accomplish it, you may leave your question in the comments below

  • Hello, is there a calculator for deferred interest?

    • I’m not clear on your needs.

      But, if you want to calculate an interest amount that would be due between any two date, then please see this interest calculator.

      If you want to create an amortization schedule with a missed payment and you want to show the accrued interest that is due, then use the Ultimate Financial Calculator. See the links to the tutorials.

      If you need something else, please ask again and provide the details.

  • Juan Cantu says:

    How do I remove the running totals? I did not have this before since I have used this calculator for years.

    • The running total goes back to the original design from the 1980s. You should have always seen them unless the payment frequency had been set to "Annually."

  • I was unable to use my amortization schedule today until I purchased a subscription. I did this and now I cannot find the Accurate Amortization Schedule that I use to use. I get a new on that I cannot get to work properly.
    Please help.

    • Thank you for subscribing to the Ultimate Financial Calculator.

      I think you are probably looking for this amortization schedule.

      If so, the subscription you should have is for SolveIT! and not the UFC.

      The UFC is more flexible and should allow you to do everything that the other amortization schedule allows you to do.

      We have two choices.

      1. You can subscribe to SolveIT! and I’ll refund in full the subscription to UFC.

      2. Or you can tell me your particulars and I can help you to figure out why the UFC is not giving you the results you need.

  • The number of months is not calculating on the financial calculator. It states “undefined” in the box. What does this mean? Thank you

    • I’m sorry you are having a problem with the calculator.

      First, are you able to make other calculations (is solving for the payment amount working)?

      If so, please send me your inputs and settings so I can see why you can’t solve for term.

      (I suggest that you reload the calculator by refreshing the page. Then, without changing anything, see if you can solve for the payment. If that works, then set the number of periods to 0, and then trying solving for number of periods. Just as a test.)

  • Robert Cranston says:

    I want to see what the difference would be if all of the monthly payment was applied to principal and interest was just added on to the end of the loan, e.g., $100,000 loan, 5% interest, $1,000 monthly payment. Each month the principal goes down by $1,000 and the interest is added on to the end of the loan. Would this save any money over normal amortization? I know the interest will be less every month, but will it be less overall? Is there any way to calculate that here?

    • You won’t be able to do that calculation with this amortization schedule.

      But you will be able to do it with the Ultimate Financial Calculator (UFC).

      If you try UFC, checkout the tutorials. There’s not one specifically for your calculation, but the tutorials should get you started. If you have any questions, just ask.

      I think what you are going to want to do is to set a series for principal first, and then enter a payment amount equal to the principal divided by the number of payments you want to make. Then do that calculation, which should leave (I think) the interest balance. Finally, you can add one final “Unknown” payment (or any number actually) and that will take care of the remaining interest. But this is just off the top of my head without actually trying what you want to do.

      Let me know please how you make out. I’m curious too. 🙂

  • says:

    How do I input exact dates I’m making payments since it’s not always on the due date?

  • Our Administrator subscribed & paid to allow me to use your product. I am unable to print, however, because your system is picking up him as the subscriber, not him. He doesn’t need or want it for himself, it’s just for my use. We need this fixed asap please.

    • Not sure what you mean by “fixed.”

      Can you login using the credentials he supplied?

      If not, let him create a new subscription with the credentials you want to use, and if the first subscription is not needed, I’ll refund the first subscription cost after it is canceled.

  • I have been able to use the amortization calculator free for awhile and now it won’t let me print them – do I have to have a subscription now to use the calculator?

  • Sorry, I missed your comment.

    As per the email you received when you subscribed, please reply to it with any questions, so that I can see all your order details.

    Also, before replying, please review what the email says? Are you sure you are accessing the subscriber’s area? If you see 3rd party advertisements, you are not on the right web page. You can’t use your old (pre subscribing) link.

  • I was wondering if the Accurate Amortization Schedule was available by itself. I only use the amortization schedule about once a month and to subscribe for so many other services seems excessive. I have used the same program for years but now I can’t print the work out. Hopefully there is a less expensive option.

    • The only subscription options are those listed on the subscription page.

      How are you using the calculator? For personal or business use?

      If for personal use and for the same loan, do you really need to print the schedule out each month? The calculator is fully functional from a calculation perspective. The only limitations are the ability to print and save data to a file. Perhaps you can buy the monthly subscription to print an updated schedule just once a year, and you can review other months online? That way it costs you less than $1 a month (since you can cancel the subscription any time).

      If for business use, give your clients the schedule with a cover page and no reference to this website and it will look as if you’ve prepared a custom schedule for them. Then a $50 a year subscription cost is an advertising expense.
