POAS & profit fundamentals

Start here if POAS and profit metrics are new — short definitions, formulas, and how they differ from ROAS.

• Glossary

  What is POAS?

  POAS — Profit on Ad Spend — tells you how much gross profit you earn for every dollar spent on ads. It is the metric profit-first merchants use when ROAS looks good but bank accounts do not.

  What is ROAS?

  ROAS — Return on Ad Spend — is the classic advertising efficiency metric: revenue generated per dollar of ad spend. Essential for reporting, but incomplete without profit context.
