Conversion Rate Calculator

Conversion rate is the share of visitors who did what you wanted, such as buying, calling or filling in a form: conversions divided by visitors, times 100. Add your ad spend to get the cost per conversion as well. The median for Google Ads Search in the accounts I can see is 7.13%.

Conversion rate formula

Conversion rate = conversions / visitors x 100

500 clicks and 36 conversions is 36 / 500 x 100 = 7.2%. The cost per conversion uses the same conversions: $2,000 of spend / 36 = $55.56. If you know the conversion rate and the cost per click, the cost per conversion is the CPC divided by the conversion rate. A $4 click at 7.2% is $4 / 0.072 = $55.56.

Conversion rates in the Google Ads accounts I can see

Each account counts its own conversions. Some count calls and forms, some count sales, so treat these as a rough guide and compare yourself with your own last quarter first.

Campaign typeMedian conversion rateMiddle half
Search 53 accounts 7.13% 4.45% to 12.22%
Performance Max 31 accounts 5.38% 3.24% to 10.40%
Shopping 16 accounts 5.36% 3.40% to 6.92%
Demand Gen 11 accounts 1.20% 0.32% to 2.60%

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.

Where a low conversion rate usually comes from

  1. The search terms. Broad match and Performance Max can spend on searches that were never going to buy. Check the search terms report before you touch the page.
  2. The landing page. The page doesn't repeat what the ad promised, loads slowly on a phone, or hides the form below a wall of text.
  3. The tracking. A tag that fires twice or not at all changes the rate overnight. My conversion tracking guide has the checks.

Questions I get about conversion rate

What is the conversion rate formula?

Conversion rate = conversions / visitors x 100. In Google Ads, visitors are clicks, so 36 conversions from 500 clicks is 36 / 500 x 100 = 7.2%.

What is a good conversion rate for Google Ads?

For Search, the median in the 53 US accounts I can see was 7.13%, and the middle half ran from 4.45% to 12.22%. What counts as a conversion changes the number a lot. An account that counts form starts converts higher than one that counts paid orders.

Should I divide by clicks or by sessions?

Use clicks for ad platform numbers and sessions for Google Analytics numbers. Do not mix them. Clicks and sessions rarely match, because one person can click twice in one session, or leave before the analytics tag loads.

How do I calculate cost per conversion?

Divide the ad spend by the number of conversions. $2,000 for 36 conversions is $55.56 per conversion.

Why did my conversion rate drop?

Check three things in order. First, did the conversion tracking change or break? Second, did the search terms change, for example after a match type or bid strategy change? Third, did the landing page change, slow down or stop working on a phone?
