Quick read

The main number to watch here is roi. A positive ROI means the investment generated more value than it cost.

Formula

ROI = ((Gain - Cost) / Cost) × 100

Return on investment measures how much profit or loss you generated relative to the amount invested. Unlike ROAS, ROI usually looks at net gain after cost rather than gross revenue compared to ad spend.

How to use this calculator

  1. 1Enter the total gain, return, or value generated from the investment.
  2. 2Enter the total cost of the investment, campaign, or project.
  3. 3The calculator subtracts cost from gain, divides the result by cost, and converts it into a percentage.

What this metric tells you

A positive ROI means the investment generated more value than it cost.

A negative ROI means the result did not cover the investment cost.

ROI is useful when you want a broader profitability view instead of only a revenue-efficiency metric.

Common use cases

  • Checking whether a campaign, tool, or project produced profit relative to cost.
  • Comparing broader investment returns across channels or initiatives.
  • Reviewing profitability when ROAS alone is too narrow.
