INVESTMENT NUMBERS

Enter your investment and return above to see the ROI.

What this tool does

An ROI (return on investment) calculator subtracts your cost from your return to get net profit, then expresses that profit as a percentage of what you put in — the standard way to judge whether a campaign or purchase paid off, and by how much.

How it works

  1. Enter the cost of your investment (ad spend, purchase price, etc.).
  2. Enter the revenue or return it generated.
  3. The ROI percentage and net profit update instantly as you type.
Example: A $1,000 investment that returns $1,400 in revenue works out to a net profit of $400 and an ROI of 40%.
