What is ROAS?

ROAS (return on ad spend) = Revenue from ads ÷ Ad spend. Example: $20,000 revenue ÷ $5,000 spend = 4x ROAS. It is the core metric behind any Google Ads ROAS calculator or ecommerce dashboard.

Benchmarks

Many DTC brands aim for 4x or higher on paid social; 2–3x can work with strong margins. Below 1x loses money on ad spend alone. For margin-aware decisions, use our ROI calculator and product profitability analyzer alongside the free ROAS calculator.

Ecommerce ROI calculator context

People searching for an ecommerce ROI calculator often need both efficiency (ROAS) and profit (ROI). Run ROAS first, then layer in COGS with ROI tools. For B2B ecommerce, the same math applies—use consistent attribution windows.
