FAQ
What is the difference between ROI and ROAS here?
ROI is profit divided by spend as a percentage, while ROAS is revenue divided by spend as a multiple. This marketing ROI calculator shows both for the same campaign.
Does the Marketing ROI Calculator send my data to a server?
No. The Marketing ROI Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
What ROAS is good?
It depends on margins; a ROAS that is profitable for one business may be a loss for another. Compare against your own break-even ROAS.
Should I include all campaign costs?
For accuracy, include media spend plus any creative or agency costs in the spend figure so the ROI reflects the true investment.
