#### Info...

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.

### Recent: 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.**

### What is ROI?

ROI or return-on-investment is the annualized percentage gained or lost on an investment (ROR, or rate-of-return is the same calculation).

Enter the "Amount Invested" and the date the investment was made ("Start Date"). Enter the total "Amount Returned" and the end date.

You can change the dates by changing the number of days. Enter a negative number of days to adjust the "Start Date". Or as you change a date the "Number of Days" will update.

The results include the percentage gained or loss on the investment as well as the annualized gain or loss also expressed as a percent. The annualized return can be used to compare one investment with another investment.

Example: If you bought $25,000 worth of your favorite stock on January 2nd 2014 and sold it for $33,000 on June 7th 2015, you would have a gain of $8,000 which is 32%. The annualized gain is 21.5%.

Now, lets say you made a second investment on January 2nd, 2015. This time for $10,000 and you sold it for $11,000 on March 1st, 2015. The gain is only $1,000 or 10%. However, annualized the gain is 82.1%. Ignoring risk (which can be very dangerous), one would generally consider the latter investment to be better than the former.

Hi

Let’s say if I started my portfolio with $100000 in 1st jan 2019

And I added another 50000 k on 1st March 2019. ( aa capital )

Then again I added another 20k on oct 1st 2019

And end of 2019 my total portfolio value is say $ 200000

So what is my ROI for year 2019

Please reply

## Karl says:

That’s an easy calculation. You just need to use a different calculator.

Please use the IRR calculator (internal-rate-of-return). This calculator allows the user to have various investments (and withdrawals). The ROI calculator, as you have discovered, only is for when there is a single amount invested.

## David Fonseca says:

If I invest $500,000 (options for 400K, 300K, 200K and 100K, depending on the number of investors with a maximum of 5) in a real estate venture where I am paid quarterly payments of 8% that are interest only, and at the end of 5 years I am paid all of my $500,000 back (owner refinancing to pay off investors and I have to accept my investment back at that time), what is my total return? I will have a lien on the property as collateral.

In above question, I forgot to state that owner will pay the $500K back as well as 40% of the appraised increase in the property value.

## Karl says:

First, you’ll need to use the IRR Calculator. The internal-rate-of-return is an ROI calculation with a cash flow. Briefly, you’ll enter the $500,000 investment and then the interest received. The final entry should be the total case amount you expect to receive if you were to fully liquidate the investment.

Once you look at the recommended calculator, if you have any questions, just ask them.

If I invest 100k on 1/1 and withdraw 10k at the beginning of every quarter thereafter (let’s assume 30k total)and my balance on 12/31 is 125k, how do I calculate my annual rate of return?

## Karl says:

You’ll need to use the IRR Calculator. The internal-rate-of-return calculator calculates a rate-of-return when there’s a cash flow. Briefly, you’ll enter the $100,000 investment and then the $10,000 withdrawals. The final entry should be the total cash amount ($125,000) you expect to receive if you were to fully liquidate the investment.

Hello, i invested in land in Mexico – Bacalar,

$ 20,000.00 USD, 15/12/2019 i bought the land,

now in days 21/07/2020 the actual price is $ 70,000.00 USD, im going to sell it and is moving forward 🙂

how do I calculate my ROI.

Regards.

hi, please fill in the calculator this way:

## R. Edwards says:

Hello,

I’m trying to calculate the annual R.O.I. for the following:

Four different invested amounts at various intervals over a two year period, then the return of a portion about six months later and a total value two years after that.

Thank You

## Karl says:

You’ll need to use the internal rate-of-return calculator. That calculator allows the user to enter multiple cash flows.

## Sarper says:

I want to invest 6000000 USD for a lab. The estimated net income is 50000nUSD/month for the first year, 100000 USD/month for the second year, 200000 USD/month for the third year and will be around this amount/month for the next 5 years. Which formula is needed to see whether this is a profittable investment and how can I play around with time and amount of money invested to make sure the investment is profitable

## Karl says:

Please use the irr calculator here. It will allow you to enter multiple cash flows.

## ShortGuy says:

When using the calcualtor for the following data, I receive an answer of 144% yet, when I calculate using ((SalePrice/PurchasePrice)/PurchasePrice)/NumDays*365 I get 91.6643% which seems reasonable.

Purchase Price 123/25

Sale Price 129.75

Days in trade 21

Where did I go wrong, or is my understanding of the calculator’s purpose wrong?

Thanks

## Karl says:

The ROI is an annualized rate of return. This means the calculator assumes you will get the same results from your investment for an entire year

ANDthat the funds are left invested for the year.The equation you are using does not allow for the reinvestment of the gain.

Here’s what I mean (with some rounding for simplicity). Using your example, the gain is $6.50 or a gross return of 5.3% over the 21 days. There are about 17.4 investment periods of 21 days in the course of a year. 17.4 periods * 5.3% gain = 91.6%. Thus this result assumes that the $6.50 profit is withdrawn from the investment at the end of 21 days.

## Akinlolu Akinsanya says:

I am investing $325,537 (equipment) that will provide savings of $64,800 per year.

The equipment is expected to last for 20 years. This means for all 20 years my total savings will be $1,296,000.

Question

1. Do I have to enter $1,296,000 in the “amount returned” section?

2. Will the date be a range of 20 years?

3. Will the “amount invested” be $325,537?

Thanks

## Karl says:

Since you, in essence, have cash flows and since money changes value over time, I think you should use this internal rate of return calculator. IRR is an ROI calculation that allows for cash flows.

I would enter -325,537 as the initial investment (thus negative) and then you can use the copy feature to enter 64,800 (positive) for each year for 20 years. For the final value at the end of the 20 years, you might also want to enter the amount you think you’ll be able to sell the equipment for since that would also represent a return.

If you have questions, you can ask them at the bottom of the above-linked page.
