ROAS calculator showing return on ad spend and break-even ratio

Marketing notice: This ROAS calculator (return on ad spend) uses revenue and spend from your attribution window—it does not pull live ad-platform data. ROAS and ACOS change when cookies, view-through rules, or incrementality differ from last-click reports.

Summary: Enter ad spend ($), revenue from ads ($), and gross margin %. You get ROAS (ratio and percent), ACOS %, net profit $, ROI %, break-even ROAS, a profitability note, and a scenario table at different spend levels holding the same revenue efficiency.

ROAS Calculator

Use this ROAS calculator to translate return on ad spend into profit-aware metrics: when margin is below 100%, a 4× ROAS can still lose money. Pair ROAS with ACOS and your break-even ROAS before you scale spend.

Campaign inputs (USD)

100% = no COGS modeled (common for lead-gen or high-level planning). Use your product margin for e-commerce.
