Cost per click is your ad spend divided by your clicks. The more useful number is the most you can pay per click, which is the most you can pay for a conversion times your conversion rate. Pick one and compare it with the $4.34 median Search CPC across the US Google Ads accounts I can see.

CPC = ad spend / clicks
Most you can pay per click = max cost per conversion x conversion rate
The second formula is the one to set bids with. A lead worth $60 at a 7% conversion rate supports a $4.20 click. If your average CPC is above that line, each lead costs more than it is worth, and a higher conversion rate is usually a cheaper fix than a lower bid. My CPC formula guide works through both with real numbers.
Search clicks cost the most because the person typed what they want. The spread is wide: in the Search accounts, the cheapest quarter paid under $2.19 and the dearest quarter paid over $5.84.
| Campaign type | Median CPC | Middle half |
|---|---|---|
| Search 53 accounts | $4.34 | $2.19 to $5.84 |
| Performance Max 31 accounts | $2.27 | $1.41 to $2.98 |
| Shopping 16 accounts | $2.48 | $1.42 to $3.69 |
| Demand Gen 11 accounts | $2.21 | $1.27 to $3.41 |
US accounts I can see through the Google Ads API that spent $1,000 or more on the campaign type and recorded a conversion, 30 May 2026 to 28 Aug 2026. The middle half is the 25th to the 75th percentile.
Industry matters more than campaign type. My list of the most expensive keywords on Google has the categories where clicks pass $50, and the conversion rate calculator shows the other half of the formula.
Divide the ad spend by the number of clicks. $1,300 for 300 clicks is $1,300 / 300 = $4.33 per click.
Multiply the most you can pay for a conversion by your conversion rate. If a lead is worth $60 to you and 7% of clicks become leads, a click is worth $60 x 0.07 = $4.20. Above that, every lead costs more than it is worth.
In the 53 US accounts I can see that spent $1,000 or more on Search, the median was $4.34 and the middle half paid between $2.19 and $5.84. Legal, insurance and home services pay far more. Some keywords cost over $100 a click.
No. In the Google Ads auction you usually pay less than your maximum: enough to beat the ad rank of the advertiser below you. With Smart Bidding, Google sets the bid for each auction, so the average CPC is the number to watch.
Raise Quality Score by matching the ad and the landing page to the keyword, cut the searches that never convert with negative keywords, and check whether your bids are higher at times or places that convert worse.
