How to Calculate Google Ads ROAS
ROAS (Return on Ad Spend) for Google Ads is calculated as: ROAS = Revenue Generated ÷ Ad Spend. If your campaign spent $500 and generated $2,500 in revenue, your ROAS is 5×. But ROAS alone doesn't tell you if you're profitable — for that, you also need your margin.
Break-even ROAS = 1 ÷ Net Profit Margin. At a 25% margin, your campaigns must hit at least 4× ROAS to cover ad costs. The break-even CPC is equally important: Break-even CPC = AOV × CVR × Net Margin. If your break-even CPC is $0.36 and you're paying $0.80 per click, every click loses money regardless of ROAS.
ROI measures true profitability: ROI % = (Gross Profit − Ad Spend) ÷ Ad Spend × 100. A campaign with 5× ROAS and 30% margin earns $1.50 gross profit per $1 spent — a 50% ROI. This calculator computes all three metrics simultaneously so you can evaluate any campaign scenario in seconds.

FAQ
Common questions
What is a good ROAS for Google Ads?
For ecommerce, a ROAS of 4:1 is a common baseline; 6:1+ is considered strong. The right target, however, is your break-even ROAS — calculated as 1 ÷ your net profit margin. A product with a 25% margin needs a minimum 4× ROAS just to break even on ad spend. Anything above that is profit.
How do I calculate break-even CPC for Google Ads?
Break-even CPC = AOV × Conversion Rate × Net Margin. Example: a $60 AOV product with a 2% conversion rate and 30% net margin has a break-even CPC of $0.36 ($60 × 0.02 × 0.30). Any click costing more than this erodes profit on that order.
How do you calculate ROI for Google Ads?
Google Ads ROI = (Revenue − Ad Spend) ÷ Ad Spend × 100. A campaign spending $1,000 that generates $4,500 in revenue at a 30% margin earns $1,350 in gross profit. ROI = ($1,350 − $1,000) ÷ $1,000 × 100 = 35%. This calculator computes it automatically for any inputs you enter.
What is the average conversion rate for Google Ads ecommerce?
The average ecommerce conversion rate for Google Ads search campaigns is 1.5%–3%. Above 3% is considered strong. Display and YouTube campaigns typically run 0.5%–1%. Shopping campaigns average around 1.9%. Use your actual store CVR in the calculator for the most accurate projections.
