Max CPC Calculator

CPC (cost per click) is what you pay each time someone clicks your ad. Your break-even CPC depends on how much profit you keep per conversion (max CPA for ecommerce, max cost per lead for lead gen) and how often clicks convert. Bid above break-even CPC and you will lose money even with good traffic.
