What is a marketing ROI calculator?

A marketing ROI calculator is a ready-built spreadsheet that turns your campaign numbers into a clear return on investment, comparing up to three marketing initiatives side by side. Plug in cost, audience size, conversion rate, and average sales revenue, and it calculates ROI and ROI% automatically.

What's inside the template?

The calculator covers four inputs and two calculated outputs, across three initiative columns plus a total:

  • Total marketing cost
  • Total circulation/audience
  • Conversion rate (% of leads that will purchase)
  • Average sales revenue
  • ROI (calculated)
  • ROI% (calculated)

How to use the template

Enter your figures into the boxes for each initiative, everything else is calculated for you, including the totals column. If you want your ROI shown as a percentage, copy the ROI figure into the ROI% row and it converts automatically.

Run the same initiatives through side by side rather than one at a time, since the real value of this calculator is comparing them against each other, not just checking whether one cleared zero.
