Step by step
- 1Create two columns: Initial Investment / Cost (A) and Final Value or Return (B).
- 2In the ROI column, enter =(B2-A2)/A2. This divides the net gain (B2 minus A2) by the initial investment.
- 3Format the result as Percentage. A positive value indicates a gain; negative indicates a loss.
Tips
- To annualize ROI over multiple years, use: =((B2/A2)^(1/years))-1, which gives the compound annual growth rate (CAGR) instead.
