Enter the investment cost and final value or gain. The calculator shows the net gain or loss and return on investment percentage.
Formula used
ROI = (Final Value − Investment Cost) ÷ Investment Cost × 100.
Example calculation
If an investment costs $5,000 and returns $6,500, the net gain is $1,500 and ROI is 30%.
What the result means
A positive ROI means the investment gained value. A negative ROI means the investment lost value.
