What it measures
Facebook ad ROI is the profit you earn relative to your ad spend, expressed as a percentage return.
Formula
ROI = (Revenue − Ad Spend) ÷ Ad Spend × 100 · ROAS = Revenue ÷ Ad Spend
Worked example
Earning $8,000 in revenue from $2,000 in ad spend yields $6,000 profit, a 300% ROI and a 4× ROAS.
Typical benchmarks
- Common ROAS target
- 3-4×
- Break-even (33% margin)
- ~3× ROAS
- Strong campaign ROI
- 200%+
How this calculator works
ROI = (revenue − ad spend) ÷ ad spend × 100. ROAS = revenue ÷ ad spend. A ROAS of 3–4× is a common profitability target for e-commerce, though break-even depends on your margins.
Frequently asked questions
What's the difference between ROI and ROAS? +
ROAS is gross revenue per ad dollar. ROI factors profit (revenue minus spend) against spend. ROI accounts for cost; ROAS is a simpler top-line ratio.
What ROAS do I need to be profitable? +
Break-even ROAS = 1 ÷ profit margin. At a 33% margin you need roughly 3× ROAS just to break even, so aim higher for actual profit.
Can I have a high ROAS but still lose money? +
Yes. ROAS ignores product and overhead costs, so a 3× ROAS can be unprofitable if your margins are thin. Calculate ROI on profit to confirm you are actually making money.
How do I improve Facebook ad ROI? +
Lower acquisition costs with better creative and targeting, raise conversion rates on the landing page, and increase average order value through upsells and bundles.
Should I include creative and agency costs in ROI? +
For true business ROI, yes. Add production, tools, and management fees to your spend figure; the ad-platform ROAS only reflects media cost.
