The method
How it is worked out
ROI = F − II × 100
- F
- Final value
- I
- Initial investment
ROI Calculator
Measure return on investment from cost and gain, including percentage and absolute profit or loss. The result updates as you type so you can compare scenarios quickly.
Keep in mind
What it leaves out
- TimeTotal ROI ignores how long it took. Check the yearly figure too.
- Hidden costsYour own time, fees and tax aren't counted unless you include them.
- RiskTwo investments with the same ROI can carry very different risk.
Use the calculator to compare scenarios rather than as a guaranteed forecast.
About the ROI Calculator
Measure the overall return on a project, campaign or investment from its initial cost, final proceeds and holding period. This is useful when comparing a business initiative's profit against the amount committed to it.
How it works and an example to tryShow less
How to use the result
Return on investment divides final value minus initial investment by the initial investment; the tool also calculates an annualised rate from the entered holding period. The result depends on including all meaningful costs in the initial figure and all proceeds in the final figure. It does not adjust for risk or account for fees and tax unless you include them.
Example to try
Use a marketing campaign as an example: enter the full spend and revenue or final value attributable to the campaign, then choose the period. Compare total ROI with yearly ROI. A campaign with impressive revenue is not necessarily profitable if fulfilment costs were left outside the inputs.

Who uses it, and when
Marketing teams justifying a campaign, business owners weighing a new machine or software licence, and investors comparing projects that ran for different lengths of time.
Mistakes worth avoiding
- Leaving costs out of the investment figure so the return looks better than it was.
- Comparing total ROI across projects of different lengths instead of annualising.
- Ignoring the risk taken to earn the return.
