What Is a Good ROAS for Small Business Ads?
ROAS (Return on Ad Spend) tells you how much revenue you're generating per dollar of ad spend. Here's what's good, what's acceptable, and what's a problem.

Short answer
A good ROAS depends on your margins, but 3:1 ($3 revenue per $1 spent) is often used as the baseline target. eCommerce businesses with 30–50% margins typically need 3–4x ROAS to be profitable. High-margin businesses can profit at 2x.
How ROAS is calculated
ROAS = Revenue from ads ÷ Ad spend
If you spent $1,000 on ads and generated $4,000 in revenue: ROAS = 4x
What ROAS means in practice
| ROAS | What it means | |------|--------------| | 1x | Breaking even (revenue = ad spend) | | 2x | Likely losing money after COGS and overhead | | 3x | Profitable for many businesses | | 4–6x | Strong performance | | 7x+ | Excellent, rare for most industries |
Why ROAS isn't the whole picture
ROAS only measures revenue vs ad spend. It doesn't account for:
- Cost of goods (COGS)
- Fulfillment and shipping
- Overhead and salaries
A business selling products at 25% gross margin needs a 4x ROAS just to break even on ad spend.
MER (Marketing Efficiency Ratio): a better metric
Total revenue ÷ total marketing spend = MER. This gives a holistic view of your overall marketing performance, not just one channel.
Target ROAS by business type
| Business type | Minimum profitable ROAS | |--------------|------------------------| | Physical products (30% margin) | 4x | | Digital products (80%+ margin) | 1.5–2x | | Services (50%+ margin) | 2–3x | | SaaS (high LTV) | 1–2x (short-term) |
