Why UX friction is expensive in E-commerce.
Cart abandonment is almost entirely a UX problem
Research shows 69% of online shoppers abandon carts. The top reasons — surprise shipping costs, forced account creation, too many steps — are all UX problems that can be fixed without changing your product or pricing.
Mobile conversion gap is leaving half your revenue on the table
Mobile drives 70%+ of e-commerce traffic but converts at 3× lower rates than desktop — almost entirely due to UX. Closing the mobile gap alone often represents 15–30% more revenue from existing traffic.
A 1% conversion improvement is multiplicative
For a store doing $50k/month at 2.5% conversion, improving to 3.5% adds $20k/month. That's the same revenue as a 40% increase in ad spend — with zero additional acquisition cost.
Common questions
What numbers should I use in the calculator?
Use your monthly unique visitors, your overall store conversion rate (orders / visitors), and your average order value. If you want to isolate checkout abandonment, use sessions that reached checkout as your visitor count.
Our conversion rate is 2.1%. Is that normal?
Industry median is 2–3%. Well-optimised stores in most categories reach 5–8%. The calculator shows what each percentage point improvement is worth monthly and annually so you can prioritise UX investment correctly.
Does this include mobile vs desktop split?
The base calculator uses your blended conversion rate. For a mobile-specific analysis, run it twice — once with your mobile traffic and mobile conversion rate, once with desktop — to see where the bigger revenue leak is.
