How it's calculated
ROI = (Amount returned − Amount invested) ÷ Amount invested × 100
Annualized ROI = (Amount returned ÷ Amount invested)^(1 ÷ years) − 1
- Use annualized ROI to compare a 6-month campaign with a 3-year investment.
- Marketing ROI is only as accurate as attribution. Count only revenue the campaign actually caused.
- For ads specifically, ROAS (revenue ÷ ad spend) ignores margins. ROI on profit is the stricter test.
