ROI formula and meaning
Return on investment is commonly calculated as (gain from investment − cost of investment) ÷ cost of investment × 100%. It expresses profit or loss relative to the original cost.
Example ROI calculation
If an investment costs 5,000 and returns 6,250, the profit is 1,250. Dividing 1,250 by 5,000 gives 0.25, or a 25% ROI.
ROI does not include time by itself
A 20% return earned in three months is different from 20% earned in five years. For multi-year comparisons, consider an annualized measure such as CAGR and include fees, taxes and cash flows where relevant.
