What Is a Good ROAS for Facebook Ads?
A 3.2x ROAS sounds great until your accountant tells you you're barely breaking even. That's because ROAS measures revenue per ad dollar, not profit. If your product margin is 40%, a 3.2x ROAS translates to just 28% ROI. Whether that's good depends on your alternatives and your growth stage, but it's a lot less impressive than "3.2x" makes it sound.
Here's what ROAS actually means, the benchmarks by industry, and the break-even ROAS for your margin.
ROAS vs. ROI
ROAS = Revenue ÷ Ad Spend
Tyler spent $8,000 on Facebook ads, generated $25,600. ROAS = 3.2x.
ROI = (Profit – Ad Spend) ÷ Ad Spend
Tyler's product margin is 40%. Gross profit: $10,240. ROI = ($10,240 – $8,000) ÷ $8,000 = 28%.
3.2x ROAS sounds great. 28% ROI is just okay.

The ROAS You Need to Be Profitable
| Gross Margin | Break-Even ROAS |
|---|---|
| 20% | 5.0x |
| 30% | 3.3x |
| 40% | 2.5x |
| 50% | 2.0x |
| 60% | 1.67x |
| 70% | 1.43x |
Tyler's margin is 40%, so break-even is 2.5x. At 3.2x he's profitable but thin.

Frequently Asked Questions
What does ROAS stand for?
Return On Ad Spend. It measures revenue per dollar spent on advertising. 3x ROAS = $3 revenue per $1 ad spend.
Is 2x ROAS good?
Depends on margins. At 50%+ gross margin, 2x ROAS is profitable. At 30% margin, 2x means you're losing money. Always calculate your break-even ROAS first.
Why is my ROAS declining over time?
Common causes: ad fatigue, increased competition driving up CPMs, audience saturation, seasonal shifts. Refresh creative every 2–4 weeks and test new audiences.
