Ultimate Financial Calculator

Calculate any unknown for regular & irregular cash flows. Create printable reports with dates for loans or investments. Solve for:

  • Present Value (PV)
  • Future Value (FV)
  • Payment amount, rate or term
  • Annualized rate-of-return
  • Penny perfect payoff amounts

The Ultimate Financial Calculator (UFC) is the most sophisticated, most flexible calculator on AccurateCalculators.com and I think on the entire internet.

What is a flexible payment calculator?

A flexible payment calculator supports flexible payment loans, or "flex" loans. It is a calculator, like the Ultimate Financial Calculator, that allows the user to enter payments for any date and amount.

See the tutorials for step-by-step guides.

If you are someone who needs date accurate results with either regular or irregular cash flows (loans, payments, deposits, withdrawals, investments), this is the calculator you should study and use.

Recent changes and enhancements

  • Jan. 10, 2024: Changed the default long and short-period interest options under "Settings." This means you will not get the same results you previously had unless you reselect your preferred setting.
  • 2023: Save any schedule's data to Word/docx or Excel/xlsx files. Click on "Schedule" then "Continue" past the title page.
  • The calculator automatically sorts the cash flow prior to file save and calculation. This fixes the issue where the "Unknown" did not calculate due to overlapping dates in different cash flow series unless the user had clicked the "Expand" button.

*What are 360, 364, 365 and 366 day years?

The days-per-year option impacts interest rate calculations. The calculation divides the nominal annual rate by 360 for equal length periods, 365 for actual length periods, and 366 if a leap year. Advanced calculators, such as the Ultimate Financial Calculator, give the user the ability to select the days-in-year. You will see the impact to interest when there are odd days (that is, irregular periods), or when compounding is set to daily or exact. Many other calculators on this site support this option.

200 Comments on “Ultimate Financial Calculator”

Join the conversation. Tell me what you think.
  • Problems with ultimate financial calculator.
    1. Borrower made an extra payment about a week after that month’s payment, making for 13 payments that year. I added that & it seems to have worked fine with default rounding (zero balance at end).
    2. Having difficulty arriving at total loan payoff at a certain date.
    If I follow tutorial I get the extra payment repeated over remaining loan term.
    I got an error message “unable to add periods”.
    If I change rounding to none, the extra payment “repeats” over the remaining term.
    I’m not understanding the tutorial very well.
    Also wish you had a Mac version. Thanks

    • Thanks for trying my calculator, Ken.

      A few pointers and questions.

      The extra payment won’t repeat (or shouldn’t) if in the "# Periods" column, in the extra payment row, you’ve entered a "1."

      The concept is you can enter in each row the number of payments that repeat and for which the payment was paid precisely on the date due. So, if the payments are due on the first, and you received 18 payments paid on the first, enter 18 in the "# Periods" column. Then if you received 1 extra payment, the next row should have that extra payment (for any amount on any date).

      Not sure which tutorial you are referring to, but since you are tracking loan payments, I suggest that you take a look at this tutorial. After looking at it, if something is not clear, please ask again and please refer to the step that’s giving you a problem.

      Also, I would start again entering the loan payments with the rounding set to "Open Balance."

      • Tutorial you mention/link is what I’m reading/using. Scenario:
        Make/calculate loan w/amortization schedule.
        Borrower makes an extra payment some days after the regular payment for that period. <- How do I update the existing schedule for that?
        Later on… Borrower wants to pay it off on some date, how to enter that?
        Also, if I load the schedule with the extra payment in that year (13 payments that year), then expand & collapse it, it replicates that extra payment, in this case 21 times. I wonder if it thinks that payment will be added every remaining year.

        • You say, “Make/calculate loan with an amortization schedule.” This sounds to me as if you have a schedule of the projected payments – payments that are due over the entire term of the loan. Is that the case? And if so that one good?

          If so, great.

          Now it seems you want to track actual payments. Forget the first schedule. Start again. But enter the payments as they are made for an ACTUAL schedule, NOT a projected schedule.

          Enter the payments up to the extra payment you mentioned. Then enter the extra payment. Then continue in the next row with the regular payments until the borrower wants to pay the loan off.

          In the final row, enter the date the borrower wants to pay the loan off and enter “Unknown” for the amount. Enter “1” for the “# Periods.” Then calculate. The calculated amount will be the balance due as of the date entered.

          I asked you to tell me what step in the tutorial gave you a problem. Also, did you have “1” for “# Periods” in the extra payment row?

        • Let’s assume for simplicity that all regular payments are paid on the date they are due. Also, assume there is one extra payment. And you want to know the pay-off amount the borrower has to pay to pay off the loan early.

          This will take 5 rows in the calculator.

          1. The loan amount row.
          2. The regular payments before the extra payment.
          3. The extra payment row with the date paid, the amount paid and 1 for “# periods”
          4. Then a row with the regular payments that will be paid before the proposed pay-off date
          5. Finally, the 5th row will contain the pay-off date, “Unknown” for the amount and 1 for “# Periods”

          Are you approaching the calculation this way?

      • Yes, a “1” in that extra payment, 13 payments in that year instead of 12. If I expand & then collapse that schedule, somehow it makes 21 of those extra payments, I’m guessing for the remainder of the loan term.
        What’s the difference between the ultimate financial calculator & the loan payoff calculator? They both look & work the same to me; wonder if they can save/use the same xml files they generate.
        Thanks for your help.

        • The two calculators are the same.

          Do you want to send me your XML file, and I’ll take a look? The email address is on the contact page. Link at the bottom of the page.

        • Thank you for sending the XML file. That helps. I see a few things that are “off,” but I am unsure if fixing just these items will give you the schedule you need. There may be other things I’m not aware of yet.

          1. There is no extra payment entered, as you said. If row 5 on 11/22 is supposed to be the extra payment, then under the “Series” dropdown, select “Xtra Pmt.” But also, why is the amount $0?
          2. Secondly, there are overlapping dates between the rows. Row 3 has an end date of 1/11/2020, while row 4 starts on 7/5/2018. This is not ideal. Rows should be in date sequence, and they should not overlap this way (overlap means an end date coming after the start date in the next row.)

          Is suggest starting simple. Briefly, forget about your loan details and step through some of the tutorials so that you grasp this calculator’s concepts. I also suggest trying the 5-row example, as I mentioned in the prior reply.

          • 1. The extra payment somehow got replicated 20 times; should be ONE extra payment, 6 days after the regular one. Until I figure out some reason for that “replication” I’m considering it a bug. It happens anytime I expand/collapse the schedule (also another version of the schedule that doesn’t attempt the payoff). Row 5 is effort to make a payoff on that date (11/24) & it doesn’t “look right” in the schedule.
            2. I don’t know why the dates overlap. I entered the ONE extra payment as above. That year had 13 payments & the extra one happened 6 days after the regular payment. As to whether it applies to both principal & interest or principal only, I’m inclined to apply it to interest too, since there’s a time difference, but I’m open to ideas.

          • Let’s address one thing at a time. For now, we won’t worry about calculating the early pay-off amount. Also, forget about Expand and Collapse for right now. You don’t need those features (at this point).

            You keep saying “extra payment,” but as I said, looking at what you sent me, you haven’t indicated that any of the payments are extra payments. Other than the first loan row, the only row that has a “1” in the “# periods” column is row 5. That row has a $0 amount. Why? And it’s not marked as “Xtra Pmt” (in the Series column).

            If you had intended for another row to be a single extra payment, the rows have values other than “1” in the “# Periods” column.

            The reason why the dates overlap is because of date math. For example, row 3 represents a series of 21 monthly payments starting on 5/11/2018. The last of the 21 payments ends on 1/11/2020. But row 4 starts a new series on 7/5/2018 of 53 payments before the series in row 3 has even been completed. What you are telling the calculator to do, is to create overlapping series. Is that what you want?

          • I understand now that you are saying row 5 is an attempt to calculate a pay-off amount and not an attempt to make an extra payment. What row is the single extra payment? That row needs to have “1” in the “# Periods” column, and it needs “Xtra Pmt” set under “Series”.

          • I think maybe this is what you want?

            Row 5 is the unknown payoff amount as of Nov 24, 2022.

            The payoff amount ALWAYS has to be the last row of the calculation. Makes sense, right?

    • Jerry J. Box says:

      The print out is very light?

      • Not sure why that would be. The text should be black or perhaps very dark gray. What browser are you using and what printer driver? Are you using Windows? What happens if you first create a PDF and then print the PDF (all modern browsers should let you select PDF as the destination when you print.)

      • I did make a change today that might help the printing problem with the text being too light. Please give it a try again.

        If you do not see an improvement right away, you may have to perform a hard refresh of the page:

        Depending on your operating system all you need to do is the following key combination:

        • Windows: ctrl + F5
        • Mac/Apple: Apple + R or command + R
        • Linux: F5

  • Lee H Johnson says:

    I entered the loan amount and interest rate. The contract calls for payments of 982.85 per month which was the first month payment but we made greater payments after that e.g. $1,067.59 the next month, then $1076.23 and varying payments after that. The program won’t let me enter payments after the 8th payment. What to do?

    • Can you say why the program is not allowing you to enter more payments after the 8th payment? Do you see any error messages?

      You should be able to enter many hundreds of payments.

      Do you see where you move to the next “page” of the table using the numbers below the table?

  • Robert Sweeney says:

    Is there a version of this calculator that we can use that does not have all the ads on the page?

    • If you can use a Windows program, then C-Value ($49.95) is the same as the UFC.

      If you can only use an online calculator, the answer is “no”, at this time. But I’ll release an ad-free, online version in the coming months on a new website.

      • Robert Sweeney says:

        I already have a subscription to C-Value, but I like the ability to use this calculator in my Chromebook. Will you be sending out a notice to subscribers when that new
        site is up and running or do those interested just need to keep checking this site?

        • The old site will automatically redirect to the new site. And when the ad-free version is ready, I’ll send out a notification email. But that won’t happen until the site is up and running for a while.

  • Hi thanks for this calculator! My issue is that it isn’t saving my currency and date specifications (Aus, DD/MM/YYYY) and therefore giving a completely wrong interest rate.
    Can you please assist?

    • You’re welcome!

      Do you have cookies enabled? I was able to set the calculator to AUD and MM/DD/YYYY.

      However, neither of these settings should impact the interest rate. And I don’t understand what you mean by “giving a completely wrong” rate.

      Can you provide a specific example? If you click on the calendar button next to the date(s) is the calendar showing you the dates you expect?

  • Hi! I have used your calculator in the past with excellent results. Now there is a new link and it looks a little different. I got everything entered, but when I click on Calculate, nothing happens. What am I doing wrong?

    Thank you

    • I doubt that you are doing anything wrong. I have heard of this problem before when users access the calculator by using a favorite or bookmark that had pointed to the old website (financial-calculators.com).

      The way to fix this is to use this link Ultimate Financial Calculator. Then when the page opens, just to be sure, refresh the page by holding down "Ctrl" and typing "R" in most browsers (this is what is called a hard refresh).

      Please let me know if this works for you. And sorry for the problem.

  • Hi Karl,
    I’m trying to amortize a 10 yr loan with a fixed monthly payment and increasing rate changes every 2 years with a balloon at the end of the term. When I input the loan, pmt and each date/rate change the amortization schedule only shows the interest calc for the first month after the rate change and then -0-. I’m sure I’m just inputting it wrong. I have an example xml file but don’t see how to upload it. Thx

    • Hi Zach, You may send the file to the email address on this contact page. I’ll be happy to take a look.

    • Zach, thank you for sending the example file.

      I see what you mean. You didn’t make an error when you entered the data. However, we need to keep the inputs in date order to create a schedule.

      To achieve this, click "Expand" and then "Collapse". Once you’ve done that, you will see the schedule shows the correct interest amounts.

      (I’m assuming that you understand why the initial payments show $0 for interest – because the "Initial Interest Rate" is set to 0.0%.)

      Hope this helps.

  • djmorris52 says:

    I tried posting earlier, but don’t see my comment on here -sorry if this repeats. I have entered my numbers in the ultimate financial calculator for a fixed principal + interest schedule. I don’t find a print option. Per the tutorial, there should be one on the schedule dropdown but I don’t see it. Using answers above, I have also tried using accuratecalculators.com instead of the stored website and done the refresh using CTRL + R. Still no print option. What am I not seeing?

    • I’ve replied to your first post which is visible as the last comment on this page.

      What number tutorial are you reading? There should not be anything that says there’s a "print option on the schedule dropdown."

      For printing. Click on the "Schedule" button in the top row of the calculator. Either fill in the items in the "Include an Optional Title Page," or don’t. That’s up to you. Then at the bottom of that window (the "Include an Optional Title Page") click on the Skip button (if you don’t want the title page, or the Continue button if you do want the title page. That will take you to the schedule where you’ll see the print button.

      Let me know if this does not work for you. (The tutorial you are looking at might need to be updated to mention the new title page option.)

      • Donna Morris says:

        I read your second e-mail first. In response to the first e-mail, when I click on schedule, nothing happens. No print option, no optional title page option. I will find the tutorial I looked at and let you know.

  • Donna Morris says:

    It worked that time. Did you fix something? If not, I don’t know what was different in that time and the dozen or so other times I tried. Maybe not giving enough time for the schedule to be calculated?

  • Hey, are all the plugins available as WordPress plugins? It will be great if you can share a list of free WordPress plugins of yours.
