Cost per click
—
The CPC Calculator turns ad spend and clicks into cost per click instantly, with clicks per $100 shown for comparing budgets of different sizes.
Cost per click is the number that decides how far an ad budget stretches on a platform priced by clicks rather than impressions — search ads, most shopping ads, and a good share of social spend.
Enter total ad spend and the clicks it generated, and get the CPC straight away, along with how many clicks $100 would buy at that rate — a quick way to compare two campaigns or platforms on equal footing.
CPC updates live as spend or clicks change.
Accurate for low-cost clicks common in some niches.

Use the clicks-per-$100 figure to compare campaigns of different sizes.
CPC = Ad spend ÷ Clicks. $450 spent for 600 clicks is a CPC of $0.75.
It depends heavily on industry and keyword competition — legal and finance keywords can run several dollars a click, while niche or long-tail terms can be a few cents. Compare against your own account history rather than a universal number.
No. Most ad auctions charge less than your maximum bid, so actual CPC is usually lower than what was bid — this calculator shows the real, blended figure from actual spend and clicks.
CPC is the cost of a click; CAC is the cost of a customer. Divide CPC by your conversion rate to estimate CAC from a click-based channel.
