ROAS: definition, formula and benchmarks

ROAS (Return On Ad Spend) measures the revenue generated for every dollar spent on advertising. It's the fundamental metric for evaluating campaign profitability.

ROASReturn On Ad Spend — the ratio of revenue to ad spend

Formula

ROAS calculation
ROAS = Revenue from ads / Ad spend

Example:
  Revenue: 5,000 EUR
  Spend: 1,200 EUR
  ROAS = 5,000 / 1,200 = 4.17x

Platform ROAS is misleading

ROAS reported by Meta or Google is overestimated by 20-40%. Always cross-reference with real orders for reliable ROAS.
