POAS (Profit on Ad Spend) is the gross profit attributed to ads divided by ad spend. Unlike ROAS, it counts margin — a POAS of 2 means $2 of profit per $1 spent.
What is POAS?
POAS fixes the central flaw in ROAS: it accounts for margin. ROAS treats $100 of revenue the same whether the product cost you $20 or $90 to deliver. POAS replaces revenue with gross profit, so it tells you whether ads are actually adding money to the business, not just turnover. It matters most for businesses with varied margins across a catalog. Two campaigns with identical ROAS can have wildly different POAS if one pushes high-margin products and the other moves loss-leaders. Optimizing to ROAS can quietly scale your least profitable SKUs. Use POAS to bid and allocate budget toward profit, not revenue. The hard part is data: it requires accurate cost-of-goods at the product level, which lives in your systems — never in an ad platform.
POAS formula
POAS = Gross Profit from Ads ÷ Ad Spend
Gross Profit from Ads is the ad-attributed revenue minus the cost of goods sold (and often other variable costs) on those orders — the actual margin the sales produced. Ad Spend is what you paid for the ads. Divide profit by spend to see profit returned per dollar invested.
Worked example
A product line with known margins.
Gross Profit from Ads
$20,000
Ad Spend
$10,000
POAS
2.0x
$20,000 ÷ $10,000 = 2.0x
Platforms only see revenue, never your margin — so no ad platform can report POAS.
How POAS differs across ad platforms
Google Ads
Google can ingest profit-based conversion values if you feed it margin via conversion-value rules or a profit feed, letting it approximate POAS-style bidding. But it only knows the margin you supply — Google never sees your true cost of goods on its own.
Meta
Meta optimizes to purchase value, not profit. You can pass a margin-adjusted value through the Conversions API to nudge it toward profit, but it has no native concept of cost or margin and won't report POAS.
Your data (margin source of truth)
POAS can only be calculated correctly with product-level cost data from your own systems — ERP, ecommerce backend, or finance. No platform reports POAS because no platform knows your COGS; the moat is joining ad-attributed revenue to real margin.
Common POAS misconceptions
POAS and ROAS just differ by a fixed multiplier.
Only if every product had the same margin. With a mixed catalog, the ROAS-to-POAS gap varies campaign by campaign — which is the whole point of tracking POAS separately.
Ad platforms can report POAS if you turn on the right setting.
No platform sees your cost of goods, so none can compute true profit. The best they do is optimize to a profit value you feed them — the reporting still has to happen on your side.
