A retail conversion rate is the share of visitors who buy. You get it by dividing sales by visitors and showing the result as a percentage. Type your visitors and conversions above and the calculator gives the rate to two decimal places. Add your average order value and it also shows the estimated revenue.
What to count in a shop and online
- In a physical shop, visitors are the people who came through the door and conversions are the transactions at the till. Take the footfall from your door counter and the transactions from your till for the same day or week.
- In an online store, visitors are visits or unique visitors, and conversions are the visits that ended in an order.
Shopify counts visits, which it calls sessions. It takes the sessions that completed checkout and divides them by all sessions. One visitor might have several sessions. If you type unique visitors instead of sessions you'll get a higher rate than the one Shopify reports. Pick one and use it every time you compare.
Shopify also reports a checkout conversion rate. That one only counts visits that reached checkout, so it measures your checkout and leaves out your product pages.

What the calculator doesn't do
It doesn't connect to your till, your door counter, Shopify or Google Analytics. Copy the visitor and sale counts from them into the two boxes.
It doesn't give you a benchmark or tell you whether your rate is good. Rates depend on what you sell, the price and where your visitors come from. Compare your rate this month with last month, using the same counts for both.
