Estimate the percentage return on an investment by comparing its ending value with its initial cost. Enter your figures in the fields above and select Calculate. The result updates when you change an input.
Formula
ROI = (Value received − Initial investment) ÷ Initial investment × 100
Example and interpretation
If a $1,000 investment produces a value of $1,500, the gain is $500 and simple ROI is 50%. This basic formula does not annualize the return.
