ROAS Break

ROAS Break is an independent collection of free calculators and original decision guides for ecommerce operators and paid media teams. Its tools cover break-even and target ROAS, allowable acquisition cost (CPA), profit levers, promotion thresholds, CAC payback and scenario-level contribution profit. The guides explain how to source inputs (e.g. Shopify net sales, variable costs, returns and fees), interpret platform metrics from Google Ads, Meta, Amazon and TikTok Shop, and where the model stops. Formulas are shown on each page, the methodology is published, and calculations run in your browser. ROAS Break is published by floatboat.ai and is not affiliated with the ad platforms it references.
