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.
