How to measure Meta ad profitability

Pull spend and revenue from Meta

Meta Ads Manager > Campaigns > last 30 days. Use 7-day-click attribution (not 1-day-view) for accurate revenue attribution. Include all campaigns you want to measure.

Calculate COGS for those orders

For each order attributed to Meta, sum up the supplier cost. If you can't get exact, multiply total Meta revenue by your blended COGS ratio (e.g. 30% of revenue).

Focus on POAS, not ROAS

ROAS tells you revenue per ad dollar. POAS tells you profit per ad dollar. ROAS of 3× can still be unprofitable if your COGS is 40% and processing is 3%. POAS is the number that matters.

Facebook Ads benchmarks and reality

Meta remains the biggest paid channel for most DTC brands. Knowing what's healthy keeps you focused on the right levers.

ROAS benchmarks by category

Apparel: 3-5× ROAS. Beauty: 2.5-4×. Consumer electronics: 3.5-6×. Subscription products: 1.5-2.5× on first purchase (scale through LTV). These are purchase-event ROAS, not view-content ROAS.

iOS 14.5+ broke attribution

After App Tracking Transparency, Meta over-reports Shopify-attributed revenue by 15-30% for new customer acquisition. Your Meta ROAS looks better than reality. Blend Meta's numbers with Shopify reports (UTM tracking) for truth.

New customer ROAS vs blended

Blended ROAS (all Meta purchases) is often 4-6×. New-customer-only ROAS (excludes retargeting of existing customers) is usually 1.5-2.5×. The blended number masks which campaigns actually acquire vs retarget.

Advantage+ campaigns lift performance

Meta's AI-driven Advantage+ Shopping Campaigns outperform manual campaigns for most DTC brands. Typical lift: 15-30% higher ROAS with lower CPMs. If you haven't tested Advantage+ yet, it's the biggest optimization lever available.

CPMs spike in Q4

Meta CPMs typically run $15-25 USD for ecommerce in Q1-Q3, then spike to $35-60 in Nov-Dec as every DTC brand floods the auction. Plan Q4 budget and ROAS expectations accordingly.

FAQs

Common questions about Facebook Ads ROAS.

Depends on category and margin. 3× is healthy for most DTC brands. Apparel and beauty often need 3-4× to be net-profitable. High-margin products (software, digital goods) can profit on 1.5-2×. Focus on POAS rather than ROAS alone.
POAS (profit on ad spend). ROAS measures revenue; POAS measures actual profit after COGS and processing. A 3× ROAS on a 40% COGS product after 3% processing gives you about 1.7× POAS - still healthy. A 3× ROAS on an 80% COGS product gives you 0.6× - you're losing money.
Attribution windows, attribution models, and iOS 14.5+ privacy changes. Meta uses a 7-day-click attribution window by default, while Shopify reports first-touch UTM. Meta typically over-reports by 15-30% for new customer acquisition in the post-iOS-14 era.
Campaign-level: weekly. Account-level: monthly and quarterly. Daily ROAS swings wildly and drives bad decisions. Give new campaigns at least 50-100 conversions before judging performance.
For acquisition campaigns, yes. First-purchase ROAS of 1.5× is acceptable if customers buy 4× more over 12 months (effective LTV ROAS of 4.5×+). For retargeting campaigns, purchase-event ROAS is enough.
