How to use this tool
Replace the example values with your own inputs. Results update as you type. Keep your measurement period and definitions consistent, then use the result to inform the next question in your advertising review.
The formula
Conversion rate = converted visits ÷ visits × 100.
Worked example
250 converted visits out of 10,000 visits gives a conversion rate of 2.50%.
What the result can tell you
Count converted visits once. If your platform counts multiple conversion events per visit, its reported rate may differ.
Is it free, and where do my inputs go?
The tool runs in your browser without an account or an ad-platform connection. Calculation inputs are not sent to WhatWins. If you save a scenario, it stays in this browser on this device.
