Conversion Rate Calculator
CheckedThis conversion rate calculator divides orders by sessions, then gives revenue per session, the figure that shows which store or campaign really earns more. Free, no sign-up, and the result updates as you type.

Conversion rate ranks stores in the wrong order more often than it ranks them in the right one, because it ignores what an order is worth. A site converting 4% of sessions at a $28 basket earns $1.12 a visit; one converting 2% at a $75 basket earns $1.50, and the slower-converting site is the better business. Revenue per session settles the argument, so it is returned alongside the rate rather than buried in a separate report.
How it's calculated
Conversion rate = conversions ÷ sessions × 100 Revenue per session = revenue ÷ sessions AOV = revenue ÷ conversions

A considered-purchase store
2.00% conversion rate, $1.50 per session
250 orders from 12,500 sessions is a 2.00% conversion rate — one order every 50 visits. At $18,750 of revenue the average order is $75 and each session is worth $1.50. That per-session figure is the ceiling on what traffic can cost: pay more than $1.50 a visit and the store loses money before goods are even counted.

A fast-converting, low-basket store
4.00% conversion rate, $1.12 per session
1,600 orders from 40,000 sessions is a 4.00% conversion rate, double the first store, and it converts every 25 visits. But the $28 average order drops revenue per session to $1.12. The higher-converting store can afford 25% less per click, which is why conversion-rate comparisons between businesses are close to meaningless without the basket size beside them.

Questions sellers ask
How do you calculate the conversion rate?
Divide conversions by sessions and multiply by 100. 250 orders from 12,500 sessions is 2.00%. Decide first whether the denominator is sessions or unique users, because the same data yields a noticeably higher rate on users — one person browsing across three visits before buying counts once as a user and three times as a session.
What is the conversion rate right now?
Across ecommerce, most stores sit between 1% and 3%, with the median around 2%. Desktop typically converts roughly twice as well as mobile, and paid search traffic converts better than paid social because the intent arrived with the click. Your own trailing 12 weeks is a far better benchmark than any of these, since product category moves the number more than any optimisation will.
Is 20% a good conversion rate?
For ecommerce it is extraordinary and usually a measurement artefact — a checkout-only tag, a returning-customer segment, or bot traffic filtered from one number and not the other. For a branded search campaign, an email list or a lead form behind qualified traffic, 20% is realistic. Check what counts as a session before celebrating a rate an order of magnitude above the category norm.
What is the formula for conversion rate?
Conversion rate = conversions ÷ sessions × 100. Two derived figures matter more for decisions: revenue per session, which is revenue ÷ sessions and caps what you can pay for traffic, and sessions per conversion, which is the reciprocal of the rate and tells you how much traffic a test needs. At 2%, spotting a change worth half a point takes tens of thousands of sessions per variant.
