As a side benefit of this calculator's date accuracy, you can also use it to do date math calculations. That is, it will find the date that is "X" days from the start date or given two dates, it will calculate the number of days between them.

Calendar Tip: When using the calendar, click on the month at the top to list the months, then, if needed, click on the year at the top to list years. Click to pick a year, pick a month, and pick a day. Naturally, you can scroll through the months and days too. Or you can click on "Today" to quickly select the current date.

If you prefer not using a calendar, single click on a date or use the [Tab] key (or [Shift][Tab]) to select a date. Then, as mentioned, type 8 digits only - no need to type the date part separators. Also, because the date is selected, you do not need to clear the prior date before typing. If your selected date format equals mm/dd/yyyy, then for March 15, 2016, type 03152016.

Updated 09/15/2019: Your desired ROR

At some point, a user might need to know what they should pay for an investment to achieve a desired return-on-investment. Or what they need to sell it for if they have already entered into the invesetment.

With the most recent update, this calculator can now perform either calculation. All the user need do is provide the goal ROI (and click "Calc" to update). The calculator calculates the adjustment amount required for both the initial investment and the final value. It also calculates the absolute amount for both.

To double-check the accuracy of the results, copy and paste the value into the appropriate location and recalculate. The ROI should now equal your goal ROI (plus or minus a minimal rounding amount).

And now for an essential word about ROI/ROR financial calculators.

  • If i invest $100,000 for 36 months and I get $140,000.00 at the end of my investment, what is my Rate on Return on an annual basis?

  • If I invest $520,000 and I have annual overhead of $458,000/year and a profit of $600,000/year what would my ROI be over 5 years and 10 years?

    • Since you are dealing with cash flows, you shouldn’t (can’t) use this calculator. Please use the IRR Calculator. IRR is an annualized return-on-investment calculation.

      If you try the calculator, I think you’ll probably want to set the cash flows to annual.

      You’ll enter $-520,000 as the initial investment (investments and expenses are entered as negative values), while returns are entered as positive values.

      Do you take the profits out each year? Or are they retained. If retained, you’ll enter your expenses each year, and the sum or the profits as an ending value (+) at 5 years and 10 years.

      Hope this gets you started.

  • If my investor wants 10% interest on his 18 month $600,000 investment. How am I to calculate this?
    Amount Invested (PV)?: $600,000.00
    Amount Returned (FV)?: $692,304.00 OR $660,000 *
    Days (-9,999 < # 1969)?: 10/15/2019
    End Date (year < 2100)?: 04/15/2021
    Gain or Loss: $92,304.00 OR $60,000 *
    Percentage Gain or Loss: 15.3840% OR 10% *
    Annualized Return (ROI): 10.0000% OR 6.5540% *
    Total Years: 1.5

    • The answer to your question depends on what your investor means when he says he "want 10% interest on his 18 month investment?"

      Does he want 10% on an annualized basis? Then the answer is $692,304.

      Or does he want a 10% gross return on his investment. Then the answer is $660,000. If your investor means this, then he is very generous, because if the payment slips to say June 15, 2021, the amount returned would not change.

      Usually investors think in annualized terms when they are thinking about interest earned. Specifying an annual interest rate allows them to compare two investments with different terms.

    • I’ll point one other thing out too. A 10% ROI is not exactly the same thing as a 10% interest rate. An interest rate gets into details about compounding and day count methods. An ROI or IRR (internal rate of return) eliminate these details from the calculation.

      I’m mentioning this in case you consider this to be a loan. You can use this calculator to create a loan and have the calculator calculate the single payment amount with a 10% annual interest rate, and you’ll get a different answer than $692,304 – for the reasons mentioned. Neither answer is wrong. What it comes down to, is you both agreeing on what is meant.

  • I have used your ROI calculator every day for years, but the last few days it does not compute. I enter the dates, amount invested and current amount, but it will not tell me my end-of-year ROI. What’s happened?

    • Oh, that’s not good. I can confirm that the calculator works. What most likely happened is this. I made an update this week and it’s possible that your browser has cached (retained) some of the old programming code which is not compatible with the change. If that’s what has happen, it is easy to fix. Do a "hard refresh." If you are using Chrome on Windows, you can do that with Ctrl-F5. Here’s some more info about hard refresh which might be useful.

      If a hard refresh does not fix the problem for you, please give me an example of a calculation that does not work, and I’ll test on my end.

      Also, if above does not work, do you have another browser installed that you can try?

  • I’m not sure if what I’m looking for will really work – but we are looking to bring on a new service line. Total cost of capital required (69,308.09) + service agreement (83,777) for 2 year agreement should yield a low estimate of 60 procedures performed. Each procedure averages $4,021.
    PV 153,085.09
    FV 241,260

    Is this an appropriate use of the calculator? Thank you.

    • It seems as if your investment has a cash flow component. Therefore, if I understand you correctly, this calculator would not be the right one. You should use the IRR Calculator. The IRR calculator is used to calculate an annualized return when there is a cash flow.

  • I have an investment of 170,000 in ETFs that provides periodic dividends ( total of $1800 for the year) – that are fully reinvested. At the end of the year, my investment has grown to 178,000 in market value. How would I use the above calculator?

    In my simple mind, my ROR is 178000/170000, or 4.70%.

    And if this is not the right calculator, what is the right way?

    • Your math is correct, but it’s a gross percentage return. If the investment ($170,000) was made on Oct. 2, 2017 and the value today is $178,00, the annualized return would not be 4.7%. It would be something less.

      This calculator is fine to use. It will calculate an annualized ROI which allows you to compare the performance of say different ETFs with differing periods of ownership.

    • I’ll add, it the investment of $170,000 was not made on the same date, but rather it represents a series of investments, then you’ll need to use this IRR calculator so that you can capture the different investment dates.

      • Just to clarify,
        There was one time – one shot investment of $170,000 on April 1, 2018. The 1,800 in dividends came in 3 tranches – July 1 2018, October 1 2018 and January 1 2019. All were reinvested back. Then on March 31, 2019, the market value of original 170,000 PLUS 3 dividend reinvestments totalling 1,800, was 178,000.

        • Understood. This ROI calculator will do what you want, but your math will work as well, since the term is one year.

          Note, one year for this calculator, is April 1, 2018 to April 1, 2019. The dates are start of day.If the end date is set to March 31, then that will be 24 hours short of a year.

  • How do i calculate ROI on my super to see if my super has made good investments or not?
    Opening balance : 58832.40

    Closing balance : 67925.54

    For financial year
    Employer contributions was : 7448.87
    Fees : 2291.56
    Return : 3935.83

    Sir how would i know if my super has done good job in this financial year?.please advise

    • Since your requirement involves additional contributions and fees, you can’t use the ROI calculator.

      Rather, please use this calculator. The IRR calculator is designed to calculate an annualized rate-of-return and the user can make adjustments during the year (or over multiple years).

      If you try it, and have questions, please ask. Or I would also appreciate hearing how you make out or what you think.

  • Mohamed Salah says:

    please help
    if i have a land with 19M
    and an improvements on assets with 6M

    so here would i calculate the total invested amount on 25M or only 6M

    with the knowledge that total returns for 15 years will be 20,092,368

    • First of all, I don’t think you should be using this ROI calculator. It’s not meant for a calculation that has a cash flow.

      Please look at this IRR calculator. It’s designed to calculate a rate of return with a cash flow, which I assume the property is throwing off. Yes, you should include both the property cost and improvements in the cash flow. Then for final value, include the value of the land as well (as it might appreciate).

      Check out the suggested calculator, and if you have questions, just ask.
