Model Google Shopping or Performance Max profitability from CPC, conversion rate, CPA, product margin and ad spend — then see break-even CPA, ROAS, CPC and monthly profit.
Choose the reporting style you want to model.
Use either real account data or a planning scenario.
Use only if you have a documented CSS commercial benefit. Google requires CSS participation for Shopping ads in listed CSS program countries, but partner pricing models vary.
The calculator starts with your monthly ad spend, average CPC and conversion rate to estimate clicks, orders and CPA. It then applies your product economics to those orders so ROAS is connected to actual profit rather than revenue alone.
ROAS compares revenue with ad spend. POAS compares modeled profit before advertising with ad spend. A campaign can show an attractive ROAS while still losing money if product, fulfillment, payment or return costs are too high.
Break-even CPA estimates the maximum acquisition cost an order can support. Break-even ROAS expresses the same threshold as revenue divided by allowable ad spend. Break-even CPC uses your conversion rate to estimate the maximum average click cost that preserves break-even economics.
Google Ads supports value-based bidding such as Target ROAS for Shopping, and Performance Max can optimize conversion value across Google channels. The economics on this page remain the same: use your actual media metrics and store costs to judge whether the campaign is profitable.
Yes. Use the blended spend, clicks and conversion performance from the Performance Max campaign together with your actual ecommerce costs.
There is no universal profitable ROAS. The correct threshold depends on your gross margin and other costs. The break-even ROAS shown above is derived from the economics you enter.
Only when you have a documented commercial benefit from your CSS setup. CSS partners use different service and charging models, so the field is optional and defaults to zero.
Google says Shopping campaigns can use value-based Smart Bidding including Target ROAS, and notes that advertisers can also use Performance Max. In CSS program countries, merchants must work with at least one Comparison Shopping Service for Shopping ads/free listings, and CSS service models can differ.
