What is ROAS?
Return On Ad Spend. Revenue generated divided by ad spend. A 3x ROAS means every $1 spent on ads generates $3 in revenue. Blended ROAS across all channels is more meaningful than platform-specific ROAS.
How ROAS is calculated
ROAS = Revenue from ads / Cost of ads. A 3x ROAS means $1 of ad spend generates $3 of revenue. This does NOT mean $2 profit. ROAS does not account for COGS, shipping, returns, or tool costs. A 3x ROAS on a 50% margin product yields $0.50 net profit per $1 spent. On a 30% margin product, 3x ROAS yields $0.10 net profit per $1 spent.
Blended vs platform ROAS
Platform-reported ROAS (what Meta or TikTok tells you) overcounts by 20-50% due to attribution overlap. Blended ROAS (total revenue / total ad spend across all platforms) is more accurate. Tools like Triple Whale reconcile platform data with actual Shopify orders. Always make budget decisions based on blended ROAS, not platform-specific numbers.
ROAS benchmarks by vertical
Beauty/skincare: 2.5-4x is healthy. Fashion/apparel: 2-3.5x. Food/CPG: 3-5x (higher margin). SaaS (B2B): 5-10x (high LTV). Health/supplements: 2-4x. Home goods: 2-3x. These are blended ROAS benchmarks for brands spending $5K-50K/month on ads. Below the low end, you are likely losing money. Above the high end, you may be under-spending (could scale profitably).
Improving ROAS through creative
Creative quality is the highest-leverage ROAS improvement lever. A 20% improvement in CTR (achievable through better hooks and brand-matched creative) reduces CPA by ~20%, which directly improves ROAS. AI tools improve ROAS by enabling volume testing: more variants tested = faster convergence to winning creative = higher average creative quality = better ROAS.
