Add-to-cart to purchase ratio: what's a good benchmark?
The add-to-cart to purchase ratio measures how many cart-adds turn into completed orders, and a typical store lands around 30–40%. In other words, most items added to carts never get bought — which is normal, but also where a lot of recoverable revenue hides.
Does “add to cart” mean someone bought?
No. Adding to cart is intent, not a purchase. Shoppers use the cart as a shortlist, a price-checker, or a “save for later” — plenty add items with no plan to buy today. A sale only counts when checkout is completed and payment goes through. That’s exactly why the add-to-cart to purchase ratio matters: it measures the gap between interest and action.
How to calculate it
Add-to-cart to purchase ratio = (purchases ÷ add-to-cart events) × 100.
Example: 400 orders ÷ 1,200 add-to-cart events = 0.333 → 33%.
Two related metrics people mix up:
- Add-to-cart rate = add-to-cart events ÷ sessions (how many visitors add anything).
- Cart abandonment rate = the inverse view — the share of carts that don’t convert.
What a low ratio tells you
If your ratio is well below ~30%, the drop-off between cart and checkout usually comes from:
- Surprise costs — shipping or fees appearing late.
- A clunky or long checkout — too many steps or forced account creation.
- Weak or unclear CTAs — buyers lose momentum between “add to cart” and “buy.” See buy now vs add to cart and add-to-cart button best practices.

How to lift the ratio
- Show total cost early — no surprises at checkout.
- Shorten checkout — guest checkout and express pay.
- Sharpen the CTA — a clear verb and benefit beat “submit” (see high-converting CTA words).
- Add trust signals near the buy button — reviews, guarantees, secure-checkout badges.
The bigger picture
The cart-to-purchase gap is one of several leaks between a visit and a sale. Revyfix adds up every leak — CTAs, speed, checkout, conversion gaps — into one score and ranks the fixes by payback.
