How to calculate conversion rate
Conversion rate is the share of visitors who complete the action you measure, usually an order. 500 orders from 20,000 visitors is a 2.5% conversion rate.
Most analytics tools count sessions, not unique visitors. Pick one and stay consistent when you compare periods.

Ranges are broad industry figures. The most recent dated index (Dynamic Yield, June 2026, 400+ brands) put the global average at 2.66%, with beauty at 5.3% and home and furniture at 1.3%. Mobile converts at about half the desktop rate (2% against 3.7% in Contentsquare's retail data).
Paid social traffic converts below search traffic. Compare against your own last quarter before you compare against a benchmark.
Amazon, Etsy and Shopify do not measure the same thing
A 10% rate on Amazon and a 2.5% rate on a Shopify store can describe the same product. The denominators differ, so the numbers are not comparable.

What the metric counts |
Typical reported range |
| Own store (GA4, Shopify) |
orders ÷ sessions |
1.5% to 3% |
| Etsy |
orders ÷ visits (unique visitors, not views) |
1% to 5% per the Etsy Seller Handbook |
| Amazon (unit session percentage) |
units ordered ÷ sessions, so a 3-unit order counts three times |
often several times a store rate |
Amazon sessions come from shoppers who already searched for the product, and the metric counts units rather than orders. Etsy counts visits, so three views by one person are one visit. Benchmark each channel against its own history, not against the others.
How many orders before a change is real
Conversion rate is a proportion, and small samples swing. The standard error is the square root of rate × (1 − rate) ÷ visitors. A week with 50 orders cannot tell a real lift from noise.

A test that moves conversion from 2.5% to 3% on 2,000 visitors is inside the noise. Run it until each variant has about 17,000 visitors, or accept the risk. The same rule applies to net conversion: a 0.5% dispute rate on 500 orders is 2 or 3 orders, so judge dispute trends on quarters, not weeks.
Net conversion: the rate after orders come back
A refunded or charged-back order produced no revenue. Dashboards count it as a conversion anyway. Turn on net conversion in the advanced panel. The calculator then removes refunded and disputed orders at the rates you set.

The gap is small at average rates. It grows fast where returns are high (apparel at 20% to 30%) or disputes are common (digital goods, subscriptions). Net conversion is the number that should feed your ROAS and CAC math.
Where the visitors go: funnel conversion rates
One overall rate hides where the drop happens. Measure each step on its own. Baymard's average of 50 studies (updated September 2025) puts cart abandonment at 70.22%, so roughly 3 in 10 carts become orders.
Product page views12,000 (60%) Added to cart1,660 (8.3% of visitors) Reached checkout1,000 (60% of carts) The example is illustrative, built on the Baymard average. If cart-to-order is under 30%, the problem is checkout, not traffic. If add-to-cart is low, it is the product page or the price.
Baymard's survey of reasons for leaving (shoppers who were not just browsing) names extra costs such as shipping, tax and fees (40%), slow delivery (20%), not trusting the site with card details (19%) and forced account creation (18%).
What moves conversion rate
Page speedEach extra second of load time on mobile costs about 7% of conversions. Test on real phones over cellular.
Checkout frictionOffer guest checkout, wallet payments (Apple Pay, Shop Pay, PayPal) and fewer form fields. Forced account creation is one of the biggest drop-offs (18% of abandoners, Baymard).
Clear shipping and returns before the cartExtra costs at checkout are the top reason carts are abandoned (40%, Baymard). State shipping and the return policy on the product page.
Trust signals at paymentKnown payment logos, a visible refund policy and a matching statement descriptor cut abandonment. They cut later disputes too.
Segment by traffic sourceBranded search at 6% and paid social at 0.8% average out to 2.5%. Optimize each one on its own.
Count net, not grossA tactic that lifts orders but raises refunds or disputes can lower net conversion.
Frequently asked questions
How do you calculate conversion rate?
Divide conversions by visitors (or sessions) and multiply by 100. 500 orders ÷ 20,000 visitors = 2.5%.
What is a good ecommerce conversion rate?
2.5% to 3% is average for US ecommerce. Above 3.5% is strong. Above 5% is rare outside food, drink and repeat-purchase categories. Your own trend matters more than the benchmark.
Should I use visitors or sessions?
Either, as long as you are consistent. Sessions give a lower rate, because one visitor can have several sessions. Google Analytics 4 reports session conversion rate by default.
What is net conversion rate?
Conversion rate after you remove refunded and charged-back orders. It reflects revenue you kept. It is the right input for ROAS, CAC and LTV math.
What is revenue per visitor?
Average order value times conversion rate, or total revenue divided by visitors. It puts traffic quality and order size into one number for comparing channels.
How many more orders do I need to reach a target conversion rate?
Multiply visitors by the target rate and subtract current conversions. 20,000 visitors at 3% is 600 orders. From 500 you need 100 more. The calculator shows this line.
Is a 20% conversion rate good?
For a store it is far above any benchmark, so check the denominator first. Rates that high usually come from a marketplace metric (Amazon counts units per session), an email or returning-customer segment, or a sample too small to trust. On a full site, 20% from cold traffic almost never happens.
How do you calculate email marketing conversion rate?
Divide orders from the campaign by emails delivered, or by clicks if you want the landing page rate. 40 orders from 10,000 delivered emails is 0.4%; from 800 clicks it is 5%. Say which denominator you used, because the two numbers differ by more than ten times.
How do you convert a conversion rate into a ratio?
Divide 100 by the rate. 2.5% is 1 order per 40 visitors; 1% is 1 in 100. The ratio form helps when planning traffic: 200 orders at 1 in 40 needs 8,000 visitors.
