How to use the conversion rate calculator

  1. Choose whether you want to calculate conversion rate, conversions, or visitors.
  2. Enter the two values you already know. The calculator works out the missing value.
  3. When calculating conversion rate, optionally enter a target conversion rate to compare actual performance with your goal.

You can use visitors as website users, sessions, leads, clicks, or another consistent denominator, as long as conversions are measured against the same group.

Conversion rate formulas

Conversion rate (%) = Conversions ÷ Visitors × 100
Conversions = Visitors × Conversion rate ÷ 100
Visitors = Conversions ÷ Conversion rate × 100

Conversion rate measures the percentage of people in a measured group who complete the action you define as a conversion.

Worked conversion rate examples

If your current rate is 2.50% and your target is 3.00%, you are 50 conversions below target at 10,000 visitors.

What conversion rate can help you understand

Funnel efficiency

Conversion rate shows how effectively traffic, leads, or clicks move to the next action in your funnel.

Forecasting

A known conversion rate can help estimate how many conversions a given traffic level may produce.

Traffic requirements

A target conversion count and expected rate can be used to estimate the visitors or leads required to reach the goal.

Conversion rate vs. CTR and ROAS

CTR measures how often impressions turn into clicks. Conversion rate measures how often visitors, leads, or clicks complete a desired action. ROAS compares advertising revenue with ad spend. Looking at all three can help separate attention, action, and financial performance.

Frequently asked questions

What does a 2.5% conversion rate mean?

It means 2.5 out of every 100 measured visitors, users, leads, or clicks completed the conversion action.

What counts as a conversion?

A conversion is the action you choose to measure, such as a purchase, signup, form submission, booking, download, or qualified lead.

Should I use users, sessions, or clicks as visitors?

Use the denominator that matches your reporting method and keep it consistent when comparing periods or campaigns. Different denominators can produce different rates.

How do I calculate conversions from conversion rate?

Multiply visitors by the conversion rate and divide by 100. For example, 10,000 visitors at 2.5% produces about 250 conversions.

How do I estimate visitors needed for a goal?

Divide the desired conversions by the conversion rate, then multiply by 100. For example, 250 conversions at 2.5% requires about 10,000 visitors.

What is a good conversion rate?

There is no universal good rate. Useful benchmarks depend on channel, industry, offer, device, funnel stage, audience, traffic quality, and the action being measured.
