The Conversion Rate Calculator finds the percentage of visitors or eligible opportunities that completed a defined action, such as a purchase, signup, lead form, or trial activation.
Conversion rate formula
Enter conversions and visitors from the same date range and audience. This model assumes no more than one converted visitor per denominator unit.
Worked example
If 125 of 5,000 visitors purchase, the conversion rate is (125 / 5,000) x 100 = 2.5%.
How to compare rates
Landing-page conversion and checkout conversion have different denominators. Segment results by channel, device, geography, and new versus returning users before drawing conclusions.
Limitations
This simple rate does not establish causation or statistical significance. Analytics identity rules, consent, repeated purchases, and attribution windows can change both inputs.
