ROI = Net Profit / Cost of Investment * 100

How it works

Use this tool with clear assumptions

ROI helps compare options with different costs by converting profit into a percentage of the original investment.

When time period is entered, the annualized ROI gives a clearer view of longer or shorter investments.

Formula / logic

ROI = (final value - investment cost) / investment cost * 100.

Example

A $1,000 campaign that returns $1,450 has $450 net profit and 45% ROI.
