What it is
Marketing ROI separates winning channels from money pits. Use gross profit (not revenue) to avoid overstating returns.
The formula
ROI = (Gross profit − Spend) ÷ Spend × 100 ROAS = Revenue ÷ Spend
Why it matters
A 5× ROAS sounds great until you factor in 70% COGS — at that point, you're break-even.
