ROI Calculator – Net Investment Return
Measure net gain or loss relative to initial invested capital, including income and entered costs.
Formula
ROI = (final value + income − initial capital − costs) / initial capital × 100%.
Net gain or loss ≈ (1,100)+(50)-(1,000)-(10) · Return on initial capital ≈ (140)÷(1,000)×100
How to use
- Enter initial capital and final value.
- Add income and costs not already included.
- Read net gain and return percentage.
Examples
- 1000 invested, final value 1100, income 50 and costs 10 give ROI 14%.
