ROI basics
ROI compares net gain with initial cost.
- ROI = net gain ÷ investment cost × 100.
- Ending value mode derives net gain as ending value − investment cost.
- Annualized return uses CAGR across selected years.
- Payback is shown only when net gain is positive.
Flow
- Enter net gain and total investment cost.
- Read ROI percent and total value returned.
- Use multiple scenarios to compare investment options side by side.
Example
Worked example: campaign ROI
- 1 Net gain = 4,500
- 2 Investment cost = 12,000
- 3 ROI = (4,500 / 12,000) × 100 = 37.5%
The campaign ROI is 37.5%.
How
- Enter net gain and total investment cost.
- Read ROI percent and total value returned.
- Use multiple scenarios to compare investment options side by side.
Avoid
- Using gross revenue instead of net gain.
- Ignoring full investment cost such as setup and labor.
- Comparing ROI values across different time horizons without context.
