Google Ads Tool
Break-even CPC Calculator
Estimate the highest cost per click you can pay before your campaign stops being profitable.
How to use it
Enter conversion rate, order value, and margin, then leave yourself a safety buffer so you are not bidding right at theoretical break-even.
Best use cases
- Launching a new search campaign
- Auditing an underperforming account
- Setting bid caps for lead-gen or ecommerce offers
Common questions
Should I bid exactly at break-even?
Usually no. Most advertisers want room for tracking noise, assisted conversions, and landing page volatility.
What if conversion rate varies by keyword?
Run the calculator multiple times by campaign or offer. Segmentation makes the output more useful.
