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.

  • Hi Karl, I just want to confirm I’m using the calculator correctly to solve a problem.
    The goal- I want to calculate my yield on the purchase of a real estate note.
    The note: 180,000 @8% 360 months- pmt-$1,320.78, rate changes to 12% after 84 months, new pmt- $1,778.72.
    The purchase: 90,000 now and 90,000 after 60 months.
    I originally setup the $180K loan to solve for initial pmt at 8%, then put in a rate change after 84 months to 12% and solved for new pmt for the balance of the term (276 mo).
    Once the above was in the calculator, I changed line 1 loan from $180K to 90,000 and inserted a new row (line 3) as a loan with a date 60 months later for 90,000. I put “unknown” in the initial interest rate box at the top and hit calculate to solve for the cash flows below. It returned 13.6324%. That appears correct, but is there a more direct or different way to get there with the calculator? Also, if I knew my initial purchase was 90,000 but wasn’t sure of the 2nd pmt in 60 months, could I put 12% (desired yield) in the initial interest box, and solve for needed pmt in the 2nd installment (ie loan) box?

    You mention a premium subscription coming in 2020- is this going to replace the downloadable windows version or will it be a separate online version? Thanks. Zach

    • Hi Zach, yes, there is a more direct way to calculate yield.

      Click on "Settings" and select "Analytics" and check the include IRR on schedule option. The IRR (yield) will be in the footer of the schedule. 🙂

      And yes, you can solve for the required payment as you describe.

      The premium version will be online, and will be separate from the downloadable C-Value! program. The Windows version of C-Value! will eventually go away, but probably not right away.

  • I am trying to calculate the interest only loan repayments for a construction loan. However I notice that the first interest only payment automatically calculates the cumulative accrued interest of the all previous loan withdrawals. I would like it to accumulate all previous loan withdrawals and their respective interest into one loan and calculate interest only payments from this new combined loan amount without trying to automatically pay off all previous accrued interest. Is this possible and how would i set this up?

    • I’m not sure I understand. But for example, you are saying there are 3 loan advances, say on April 15, May 12 and Jun 8 and you want to show them as one loan? Then you would enter them as one loan. This wouldn’t be particularly accurate, but you can do it. I think I’m missing something. Can you provide a simple example?

      • Construction Loan is for 100M at 6% interest rate with 7 drawdowns & 20 semiannual payments as follows:
        1) The initial loan drawdown is for 10M on 01/08/2020
        2) then 6 semiannual (covering 3 years) drawdowns for 15M each from 01/02/2021 to 01/08/2023
        3) then 20 semiannual (covering 10 years) interest only payments from 01/02/2024 to 01/08/2033
        4) Total principle is paid as a lump sum along with the final 20th semiannual interest only payment.

        So I would like to calculate the value of each of the 20 semiannual payments. However, when making this calculation the payment scheduled automatically pays off all accumulated interest form the initial 7 drawdowns along with the 1st semiannual interest payment together. This means that the 1st of the 20 semiannual interest only payments is several times larger that all the others. I would like the 1st and subsequent 19 semiannual interest only payments to be base on the combined value of the initial 7 drawdown and their cumulative accrued interest.

        Also the 20 semiannual interest only payments are paid each year as one payment in the Interest only column when when then should be recorded and 2 separate payment every 6 months in the interest only column of the payment schedule…. If the above is not clear I would be happy to call you and clarify further.



        • Thank you for the details.

          I think the default setting should give you what you need, so I’m wondering what’s different.

          Under "Setting" select "Interest Options" and for the long period options in the first group, "Amortized" should be selected.

          Your cash flows should show 7 loan series (assuming you mean an initial loan followed by 6 loans). First for 100M followed by 6 for 10M. And actually the 6 can be combined into one row since they are occur on a regular frequency.

          In the 3rd row, you can create an interest-only payment series (did you see how to set an interest-only series by clicking on the cash flow options and selecting interest-only?)

          The final row is an unknown, normal payment row.

          I tested this, not with your exact numbers, but what I got was the expanded amortization schedule with these columns:

          #/Year  Date  Payment  Interest Due  Interest Paid  Principal Paid  Interest Balance  Principal Balance Balance

          The calculator keeps track of the interest accruing in the interest due column but no interest is paid until the first interest payment is due (per your date selection) and then after that, all payments (interest only) are for the same amount, except for the final payment which is principal and interest.

          Please let me know if this is not what you see so we can figure this out. Or even if it works for you. I like to know that too. 🙂

        • Jason, I see that I had a data entry error, and there seems that the calculator does no amortize interest-only payments. Let me look at this a little bit more. I don’t want you to waste your time.

  • I note your observation regarding the amortisation of the interest. I look forward to the outcome of your investigation on this. Thanks!

    Separately, regarding the following:

    The calculator keeps track of the interest accruing in the interest due column but no interest is paid until the first interest payment is due (per your date selection) and then after that, all payments (interest only) are for the same amount, except for the final payment which is principal and interest…… For my 20 semiannual interest only payments there should be 2 payments in each year in the column titled “interest paid”. however my payment schedule only shows 1 payment (the 1st of the 2 semiannual interest only payments) in each year in the column titled “interest paid”. I also observed that the total value of this 1 payment is equivalent to that of the 2 payments that should be displayed for each year. So in summary: For my 20 semiannual interest only payments, in the scheduled payments table section, under the column titled “Interest paid”, for each year there is only 1 figure which represents the value of both semiannual interest only paid; this is not correct as there should be 2 separate figures representing each of the 2 semiannual interest only paid for each respective year.

  • Hi Karl,

    One other observation that I would like clarification on is the following:

    For construction loan where you have multiple loan drawdowns I have observed that on the Loan Schedule page (the summary above the table at the top of the page) “Total All Payments” should be equal to the “Loan Amount” + “Total Interest Paid” but this is not the case for me. Actually the “Loan Amount” only shows the initial loan drawdowns (not the total of all loan drawdowns) but despite this the actual total loan amount (total drawdowns) + total interest paid should be equal to the total all payments but this is not what I observe. Kindly investigate this also.

    Thanks again,


    • Hi Jason,

      To the 3 open items.

      • I agree, the "Loan Amount" needs to include all loan advances rather than just the first loan advance.
      • I understand your point about seeing one payment per year, however, I can’t duplicate this. Furthermore, this version of the calculator has been posted for four years, and I would have expected a bug report on this problem long before now. Are you sure you had the "Frequency" column set to "Semiannually" for the interest-only cash flow?
      • I’ve given the periodic interest amounts a lot of thought. What you need is a calculator that will calculate a pre-computed interest amount and divide the total among all expected payments. I thought about this a few years ago and decided not to offer such an option. The problem is, when total interest is paid this way, the lender is not getting his due. The unpaid interest that is due with the first payment is, in essence, an interest-free loan. For example, if the first interest-only payment is supposed to be 50,000 (using balance and actual time) and the other 19 are 30,000, but the borrower pays 31,000 for all payments, the 20,000 difference that had been due, amounts to an interest-free loan which means the interest rate is not really 6%. (This is fine, of course, if the lender agrees.)
      • Hi Karl,

        Firstly, thank you for taking the time to investigate and provide instructive responses to my questions.

        Now to your 3 responses:

        1) I agree, the “Loan Amount” needs to include all loan advances rather than just the first loan advance….. So can you change this so that the schedule page adequately reflects the total loan amount?

        2) The problem seems to have been resolved now… Perhaps yes my initial setting had an error.

        3) For example, if the first interest-only payment is supposed to be 50,000 (using balance and actual time) and the other 19 are 30,000, but the borrower pays 31,000 for all payments, the 20,000 difference that had been due, amounts to an interest-free loan which means the interest rate is not really 6%. (This is fine, of course, if the lender agrees.)…… The first interest only payment should treat the previous loan and accumulated interest as 1 single loan amount. In your example above the 20,000 difference should be compounded (interest on interest).

        • No problem, Jason.

          1. Yes, I will fix the loan total. (I think originally, the label had said "Initial Loan Amount.") I had meant to say so. I’ve not reviewed the programming code to see what is involved, but I should be able to have an update with the fix completed by the end of June.
          2. Good. I was worried there for a moment.
          3. See the below simple example. I thought I had understood. Forgetting about a specific interest rate, the first example is the traditional interest calculation. Interest calculated on amount and term. The first interest payment is twice the amount as the other interest payments because the term is twice as long. The 2nd calculation uses precomputed interest (much like the Rule-of-78s). The total interest, for both, as you can see, is the same. To have a level interest-only payment there can not be any compounding because the days on which interest payments are actually paid are not known in advance.
                   pmt    int   prin    balance
          total int:              5,000
                   pmt    int   prin    balance
          total int:              5,000
  • Hi Karl,

    The calculator is great! It saves me with Hire purchase reconciliation. Thanks for that.

    Just wondering is there any way I could export an excel version of the schedule?



    • Thank you. I’m happy to hear that you find it useful.

      There’s no way to export the schedule. However, from the print preview, you should be able to select the text and copy and paste into Excel.

  • Hi,
    I have not read all of the post – sorry. The product looks good. I am comparing it to T-Value – trying to save some money. I used the website version. The website version does not seem to provide yearly totals. Does the final product provide this?
    Thank you,

    • Hi, I assume you are referring to the schedule? All versions of the schedule will show two total rows. An annual total and a running total, unless the cash flow is an annual cash flow.

  • Hi,

    I’m trying to calculate a fixed rate note with a fixed semiannual payment plus interest with an unknown end date.

    $122,724.99 starting on 7/1/2020
    $20,000 payment PLUS INTEREST starting on 12/1/2020 and continuing semiannually until all principal is paid
    Loan is at 6% interest

    • Hello, this calculator can easily do that.

      Enter your interest rate in the top.

      The first row will be for the loan amount

      The 2nd row will be for the payments. Click on "Cash Flow Options," and pick "Fixed Principal + Interest." Make sure you check the box to activate and enter the $20,000 principal amount. Click "Save Changes." to close the window. Under "# Periods" in the payment row, type "U" for unknown. Look at your beautiful schedule. 🙂

      Let me know if you have any other questions.

  • Roland Wentzel says:

    Hello Karl,
    When an extra payment is inserted before the first scheduled payment the Loan Summary erroneously states the payment frequency to be monthly (it was entered as semiannually) and erroneously states the periodic payment amount to be the amount of the extra payment. The amortization schedule, however, correctly shows the semiannual scheduled payments at the correct periodic payment. Why is the Loan Summary incorrectly describing payment frequency and periodic payment amount?
    Thanks in advance,

    • Hi Roland, you’re right. To answer your question, why? I guess because out of the approximately 1,500 test cases I run through this calculator, I don’t have a case that tests for an extra payment occurring before the regular payment with the payment frequency other than monthly. I expect to release an update to the site within the next 4 weeks or so. I’ll try to have this fixed by then.

      Thanks for pointing this out.

  • hi….full disclosure – I have NOT read thru all the strings (I will, I will….) but trying to do first 2 steps of entering date and $$, it will not stay in the box…keeps reverting to today….can you dope-slap me with what I am doing wrong, or…….

    I am trying to enter data from borrow date of 4Apr 18, $25,000….first payment of 800.00 was made Aug 18 2018…..

    thanks for any help, or just tell me to read the instructions AGAIN….

    • Hello, no knowing how you are trying to set the date, makes it difficult to say what is going wrong.

      First, are you using the button/calendar, or the keyboard? If you are using the calendar, then try the keyboard. Just type the numbers in the date, not the separator characters.

      If you are typing, try the calendar.

      If it still does not work, then tell me what date format you are using. MM/DD/YYYY?

  • Am trying to use the Interest Only feature, but back-date it, and there’s nothing in that particular method you are providing that allows for anything earlier than the 10/01/20 date staring down at us.. Am I missing anything in trying to find a “1st Pmt. Date”?

    • Nick, sorry, I don’t understand. The user can set the date or adjust the dates to anything they want them to be.

      What do you have set for the loan date? (assuming this is a loan) By any chance, are you trying to set the first payment date to a date before the loan date. The calculator may not allow that.

      • Yes, I was trying to set the loan date back to a 1st pmt. on 3/01/20, and the system wouldn’t let me; 36 interest-only payments.
        I found this “Interest Only” loan calculator long after I had made the loan, and wished to provide my accountant with a copy of the accumulating interest pmts., ending on 2/01/23.
        But the system won’t allow me to do that– sadly.
