How to calculate
Compare investment gain with the initial cost.
ROI = (final proceeds − initial cost) ÷ initial cost × 100
Worked example
Initial cost: 10000; Final proceeds (net of fees): 12500.
Return on investment: 25 %; Net gain: 2,500 .
Assumptions and limits
Total return for the whole period, not an annualized return. Include all relevant costs yourself.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
ROI expresses net gain or loss relative to initial cost. A 25% result means a gain equal to one quarter of that cost over the whole period.
When this tool is useful
Compare the total outcome of a completed investment or project after including relevant costs.

Frequently asked questions
Is ROI an annual return?
No. It does not use a holding period. Use annual growth rate for an annualized comparison when there are no intermediate cash flows.
Can ROI be negative?
Yes. Final proceeds below initial cost produce a negative return.
