How to calculate conversion rate
Learn the conversion-rate formula, how denominator choice affects the result, and how to interpret conversion rate in context.
Conversion rate tells you what share of your traffic completed a desired action. It is one of the simplest ways to judge funnel efficiency.
The most important detail is denominator choice. Whether you use visitors, sessions, or clicks changes the number, so comparisons only work when the definition stays consistent.
Conversion-rate formula
Conversion Rate = (Conversions / Visitors) × 100
The same structure also works with sessions or clicks if that is how your team defines the denominator.
The formula is simple, but interpretation depends heavily on what counts as a conversion and what counts as traffic.
How to calculate conversion rate correctly
- 1Define the conversion event clearly before doing any comparison.
- 2Choose the denominator that matches your reporting model and keep it consistent.
- 3Divide conversions by the denominator and multiply by 100.
- 4Review the result together with total conversion volume, CPA, and revenue metrics so the rate stays tied to real outcomes.
Worked example: conversion rate from conversions and visitors
- Conversions: 90
- Visitors: 3,000
- Conversion Rate = 90 / 3,000 × 100 = 3.0%
The result is 3.0% conversion rate. That means three out of every 100 visitors completed the tracked action.
How to interpret conversion rate in practice
- Conversion rate is often the clearest read on post-click funnel quality.
- A better rate matters most when it also supports stronger economics, not only a nicer percentage.
- Always compare rates using the same denominator and conversion definition.

FAQ
Should I use visitors or sessions for conversion rate?+
Use the denominator that matches your reporting model, but stay consistent. The absolute percentage will change depending on the definition.
Can conversion rate rise while total conversions fall?+
Yes. That can happen when traffic volume falls but the remaining traffic is more qualified.
Why is conversion rate not enough on its own?+
Because it does not tell you about order value, lead quality, or whether the conversions create healthy revenue and profit outcomes.
