CPC (Cost Per Click) is the average amount you pay for each click on your ad. It's the primary pricing model for search advertising (Google Ads, Bing Ads) and a key efficiency metric for paid social.

Formula
CPC (Cost Per Click) = Total Ad Spend ÷ Total Clicks
Clicks per Dollar = Total Clicks ÷ Total Ad Spend
How it works
This calculator divides total ad spend by the number of clicks generated to produce the average cost per click, then inverts this to show clicks earned per dollar spent, which helps compare campaign efficiency across budgets of different sizes.
CPC is an average across all placements, keywords, and audiences in the campaign; individual keywords or ad sets may have significantly higher or lower CPCs. A low CPC is not inherently good — traffic quality and subsequent conversion rate determine whether the spend is profitable.
Worked example
- Total spend = $200; total clicks = 100.
- CPC = $200 ÷ 100 = $2.00 per click.
- Clicks per dollar = 100 ÷ $200 = 0.5 clicks per dollar.
CPC = $2.00; clicks per dollar = 0.5.
Common mistakes to avoid
- Conflating average CPC with max bid — the actual CPC in auctions is typically lower than the maximum bid set.
- Optimizing for the lowest CPC without accounting for conversion rate: cheap clicks from irrelevant audiences cost more per conversion than expensive clicks from high-intent ones.
- Not separating CPC by campaign or keyword, so a few high-cost keywords raise the average and mask where spend is actually going.
Key terms
- CPC (Cost Per Click)
- The average amount paid for each click on an ad; total spend divided by total clicks.
- PPC (Pay Per Click)
- An advertising model where the advertiser pays each time a user clicks their ad, as opposed to paying per impression.
- Clicks per Dollar
- The inverse of CPC; indicates how much traffic volume a given budget produces and is useful for cross-campaign efficiency comparisons.
- Quality Score
- A metric used by platforms like Google Ads to rate ad relevance; a higher quality score typically lowers the CPC for equivalent ad positions.
- Max CPC Bid
- The maximum amount an advertiser is willing to pay per click; the auction determines whether the actual CPC is lower.
Frequently asked questions
- What is a good CPC?
- CPC benchmarks vary by industry and keyword competitiveness. Google Ads averages around $1–$2 per click for consumer categories, but competitive B2B or legal keywords can cost $50–$100+ per click. Compare CPC to your revenue per click to determine profitability.
- How does CPC relate to CPM?
- CPC = CPM / (CTR × 10). If your CPM is $5 and CTR is 1%, then CPC = $5 / (0.01 × 10) = $50. Understanding both helps you compare the true cost across different ad inventory types.
