Understanding ROAS

What is ROAS?

Return on Ad Spend measures how much revenue you earn for every dollar spent on advertising. The formula is simple: ROAS = Revenue from Ads / Ad Spend. A 4x ROAS means you earn $4 for every $1 spent on ads. For break-even ROAS, POAS and worked examples, read our guide to calculating ROAS.

Break-even ROAS

Your target comes from your margin, not a platform average. Break-even ROAS = 1 / gross margin. At a 40% margin you break even at 2.5x; anything below that loses money on every sale the ads drive.

Common Questions

What's a good ROAS?

It depends on your profit margins. A business with 80% margins can profit at 2x ROAS, while a business with 20% margins needs 5x+ ROAS to break even. Use the break-even ROAS calculation above to find your minimum.

ROAS vs ROI, what's the difference?

ROAS measures return specific to ad spend (Revenue / Ad Spend). ROI measures overall return on total investment including all costs ((Profit - Investment) / Investment x 100). ROAS is more granular for ad campaign optimization.

How do I improve my ROAS?

Optimize targeting to reach higher-intent audiences. Improve landing page conversion rates. Increase average order value with upsells. Cut underperforming ad sets. Use retargeting to convert warm audiences at lower cost.
