What this tool does

This calculator turns campaign cost and return into a simple ROI percentage so you can compare ads, tools, or freelance spend on equal footing.

Enter the same currency and time range on both sides. It does not pull data from ad accounts — you type the numbers you already have.

How to use it

  1. 1

    Enter your numbers in the fields above.

  2. 2

    Review the calculated outputs for ROI Calculator.

  3. 3

    Copy the figures you need into your brief, sheet, or ad platform.

  4. 4

    Recalculate anytime inputs change — nothing is stored after you leave.

How to read the result

ROI of 100% means you earned back the spend plus the same amount again. Negative ROI means the campaign cost more than it returned in the window you chose.

Attribute revenue honestly. If a customer found you on Instagram but converted a week later from email, do not credit the whole sale to one Reel unless that is how you actually measure.

Tips

  • Run a conservative and an optimistic revenue number instead of one best-case figure.
  • Pair with the CPC calculator when you are comparing paid traffic, not only blended ROI.

Frequently asked questions

Is a higher ROI always better?▼

Not by itself. A 400% ROI on $20 of spend is a different decision than 40% on $20,000. Use ROI to compare similar campaigns, then look at cash returned and risk.

What should I count as return?▼

Use revenue you can actually attribute to the spend in the same period — sales, booked calls, or another number you already track. Do not mix projected lifetime value with last week’s ad bill unless that is how you report internally.
