How it works
ROI = (R − I) / I × 100%
ROI = (total proceeds − investment) / investment × 100%. Include all costs in the investment. This is the return for the full period, not an annualized rate.
How ROI is calculated
ROI = (amount returned − amount invested) ÷ amount invested × 100%. Profit is the amount returned minus the investment. The investment must be greater than zero.
Worked example
If you invest 1,000 and receive 1,200 in total, profit = 1,200 − 1,000 = 200 and ROI = 200 ÷ 1,000 × 100% = 20%. If only 800 is returned, ROI is −20%.
Interpreting ROI
ROI compares two amounts; it does not annualize returns or account for the time required to achieve them. Enter consistent amounts including any costs you want reflected in the calculation. The output is not an estimate of future performance.
