What Is Add to Cart Rate? Session vs. Product Formula

How Add to Cart Rate Is Calculated

Take the sessions where someone added at least one item to the cart. Divide by all sessions in the same period, multiply by 100, and you've got it.

Add to cart rate = sessions with an add to cart ÷ total sessions × 100

A session is one visit. If a shopper adds three mugs and a teapot in one visit, that still counts as one session with an add to cart.

Example: a mug shop's October

Sessions: 12,500
Sessions with an add to cart: 950

950 ÷ 12,500 = 0.076. Times 100, that's a 7.6% add to cart rate. So roughly 1 visit in 13 put something in the cart.

Store Level vs. Product Level

People use the same name for two different numbers. The store-level rate uses sessions, like above. The product-level one asks something narrower: of the people who viewed this product, how many added it?

Product add to cart rate = adds to cart ÷ product page views × 100

Take the shop's speckled mug. It got 2,400 page views and 132 adds, so 132 ÷ 2,400 = 5.5%. You'd look at the store rate to see how the whole shop's doing, and at the product rate to spot single pages that get looks but few adds.

Just don't compare one kind with the other. In our data from 958 Shopify stores (January to June 2026), about 8 in 100 sessions reached the cart. But 6.72% of product views led to an add. The first divides by visits, the second by product views, and a single visit can include lots of product views. It's one group of stores over six months, so treat it as a rough guide, not a target. For the steps before and after this one, see how add-to-cart rate fits the Shopify sales funnel.

Finding Add to Cart Rate in Shopify

Open Analytics in your Shopify admin. Shopify splits your conversion rate into steps, and one of them is sessions that added to cart. That share is your store-level rate.

Our app, Growth Suite, also tracks the products each visitor views and their cart activity. Its Funnel Report breaks the path to purchase into five stages.

When More Carts Don't Mean More Sales

It's easy to treat an add like a sale, but it isn't one. Putting something in a cart costs the shopper nothing. Some people use it as a wishlist, or just to check the total.

Say the mug shop adds a quick-add button to its collection pages. Next month it gets 12,500 sessions again, and 1,150 of them add to cart. The rate climbs from 7.6% to 9.2%.

Orders stay at 190, though. Before, 190 of 950 carts became orders, which is 20%. Now it's 190 of 1,150, or about 16.5%. You got more carts and the same sales.

Carts leak a lot. Our Shopify cart abandonment statistics show that 58% of carts never started checkout, 43% of checkout starters didn't finish, and 76.04% of carts never became an order.

A falling rate isn't always bad news, either. A wide ad campaign can bring in casual browsers, so the rate dips while orders grow. That's why you should check this number next to your conversion rate and revenue. If plenty of people visit but few add anything, start with our guide to traffic but no sales.
