Conversion Rate Calculator
Get your conversion rate from sessions and conversions. Then set a target rate to see the extra leads, sales and revenue it adds each month, and the lift you need to pay back the work.

How the calculator works
Conversion rate is conversions divided by sessions. 200 leads from 10,000 sessions is a 2% rate. At a 2.5% target, the same traffic brings 250 leads, or 50 more a month.
For lead forms, the tool applies your close rate. If 10% of leads buy, 50 extra leads become 5 extra sales. At $2,000 a sale, that adds $10,000 a month. The last line shows how much the rate must rise before the profit from the extra sales covers the CRO work.
Before you trust the rate
Check that each lead or order counts once. Duplicate form events, thank-you page reloads and test submissions push the rate up. Compare the GA4 count with the leads in your inbox or CRM for the same month.
Use one page or one funnel at a time. A site-wide rate mixes blog readers with buyers, and the average hides where the drop-off sits.
Common questions
How do you calculate conversion rate?
Divide conversions by sessions and multiply by 100. 200 conversions from 10,000 sessions gives 2%.
What is a good conversion rate?
It depends on the offer, the traffic source and what counts as a conversion. Compare a page with its own past months and with pages that sell the same thing. Skip cross-industry averages.
Should I use sessions or users?
Use sessions for a page or campaign view, since people can convert on a later visit. Keep the same choice every month so the trend stays honest.
Why does the break-even line use profit, not revenue?
You pay for CRO work out of what each sale earns after costs. Using revenue would make almost any project look worth it.
Can I use this for an online store?
Yes. Leave the share of leads that buy empty, so each conversion counts as a sale, and enter your average order value as revenue per sale.
Do you store my numbers?
No. The math runs in your browser. Nothing goes to us unless you send the form.
