How it works
ROI = (amount returned - amount invested) / amount invested x 100.
Annualized ROI = (returned / invested)^(1 / years) - 1, the steady yearly rate that gives the same result over the holding period.
Leave the holding period at 0 to skip the annualized figure. The amount invested must be greater than 0.
Fees and taxes count only if you include them in the amounts you enter.

Questions and answers
How do I calculate ROI?
Subtract what you invested from what you got back, divide by what you invested and multiply by 100. $1,000 that becomes $1,500 is a 50% ROI.
What is annualized ROI?
It spreads the total return evenly over each year held. A 50% gain over 2 years is about 22.47% per year.
Can ROI be negative?
Yes. If you get back less than you put in, ROI is negative and the tool shows the net loss.
