Cost-Per-Click Breakeven Calculator

Cost-Per-Click Breakeven Calculator

Before launching a Google Ads or Meta Ads campaign, it's worth knowing exactly the highest CPC you can afford while still breaking even - anything above that ceiling means you're losing money on the ad spend itself.

Profit Per Order = AOV x Profit Margin%
Max Breakeven CPC = Profit Per Order x Conversion Rate%

Example

$80 average order value, 30% profit margin, 3% conversion rate:

Profit Per Order = $80 x 30% = $24 → Max Breakeven CPC = $24 x 3% = $0.72

Why This Is a Ceiling, Not a Target

This figure represents the absolute maximum CPC before an ad campaign becomes a net loss on ad spend alone - it doesn't account for other overhead costs like fulfillment, customer service, payment processing fees, or returns. Profitable campaigns should target a CPC meaningfully below this ceiling, leaving margin for those additional costs and an actual profit rather than just breaking even on the advertising line item alone.
