How the Calculation Works

The calculator compares final value with investment cost and shows the return as a percentage of the cost.
Formula Used
ROI = (Final Value - Investment Cost) / Investment Cost x 100.
Input Field Explanation
Investment Cost
Enter the original investment cost used to measure return.
Final Value / Return
