Frequently Asked Questions

What is ROAS?

Return on Ad Spend = Revenue Generated / Ad Spend. Example: $10K spend → $40K revenue = 4:1 ROAS (or 400%). Different from ROI (ROI = Profit/Cost, ROAS = Revenue/Cost).

What's a good ROAS?

Break-even ROAS depends on margins: 50% gross margin needs 2:1 ROAS to break even. Healthy targets: e-commerce 3-4:1, SaaS 3-5:1 (longer payback). High-margin businesses can profit at 1.5:1; low-margin retail needs 5:1+.

Why is my Facebook/Google ROAS dropping?

Ad fatigue (audience saturated), iOS 14.5+ tracking changes (~30% revenue underreported), increased competition raising CPMs, exhausted high-intent audiences. Solutions: refresh creative weekly, server-side tracking, expand to new channels, focus on incremental ROAS.

What's the difference between ROAS and advertising ROI?

ROAS measures the revenue generated for every dollar spent on ads (revenue / spend). ROI measures net profit as a percentage of spend ((revenue - spend) / spend × 100). ROAS is useful for comparing the gross efficiency of campaigns; ROI shows the real net return after the ad cost itself.

How do I calculate the minimum ROAS to avoid losing money?

Break-even ROAS = 1 / gross margin. If your gross margin is 35%, your break-even ROAS is 1 / 0.35 = 2.86. Any ROAS below that level means the campaign is producing a net loss even though revenue exceeds the ad spend.

Does ROAS include all costs or just the ad spend?

Standard ROAS only divides revenue by direct ad spend. It does not include product costs, shipping, returns, or fixed overhead. For a complete picture of profitability, calculate POAS (profit on ad spend): (revenue - product costs - ad spend) / ad spend.

How do I improve a campaign's ROAS?

You can improve ROAS by optimizing targeting (aim at higher-converting audiences), improving creative and messaging, lowering cost per click through a better Quality Score, raising website conversion rates, and focusing budget on your highest-margin products or services.
