How it works
- ROI is the return-on-investment ratio given by "(profit − investment) ÷ investment × 100". A value of 0% means you exactly recovered your investment, while a positive value means you earned more than you put in.
- If you do not know the profit, choose the "from revenue and cost" mode to derive profit automatically by subtracting cost from revenue. Enter expenses other than the investment itself as the cost.
- The return multiple is "profit ÷ investment", showing how much profit each unit of currency invested produced. It is a handy benchmark when comparing several initiatives.
- Even with a high ROI, a small investment limits the absolute profit. It is best to look at both the ratio (ROI) and the amount (net profit) when judging results.
- Swapping in different numbers for each type of investment, such as advertising, promotion, or inventory, makes it easier to see which initiative is the most efficient.
- The results of this tool are estimates. For real investment decisions, consider taxes, time horizon, risk, and other factors together.
