Learn the metric behind the calculator
If you want more context, these guides explain how the metric works, how to interpret it, and how to compare it with related performance measures.
How to calculate ROAS
↗Learn the ROAS formula, how to interpret the result, and when ROAS is useful versus when you need margin, profit, or break-even context too.
ROAS vs ROI
↗Understand the difference between ROAS and ROI, when each one is useful, and why revenue efficiency is not the same thing as profitability.
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
- 1Enter the total gain, return, or value generated from the investment.
- 2Enter the total cost of the investment, campaign, or project.
- 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.
