Checkout Funnel Drop-off Calculator

Most e-commerce stores know their conversion rate. Very few know exactly which step of their checkout is leaking the most revenue. Enter your funnel numbers — product page through to purchase — and this calculator shows you where the biggest drop-off is, how much revenue it's costing you monthly, and what a 10% fix at that step would recover.

How to Use This Calculator

  1. Get your funnel data from GA4 — go to Explore → Funnel Exploration. Use events: view_item, add_to_cart, begin_checkout, add_payment_info, purchase. Use 30+ days of data.
  2. Enter visitors at each step — product page visitors is your starting point. Work down through each step. You don't need all 5 — enter what you have.
  3. Enter your average order value — use your actual average from Shopify, WooCommerce, or GA4 e-commerce reports.
  4. Read the funnel visualisation — the red highlighted row is your biggest drop-off. The bar chart shows proportional traffic at each step. The summary cards show total lost revenue and what a 10% improvement at the worst step would recover.

Checkout Funnel Benchmarks

  • Product page → Add to Cart: Average 8–12%. Below 6% = product page problem (price, images, trust signals, description)
  • Add to Cart → Checkout Start: Average 35–50%. Below 30% = cart page friction (unexpected costs, forced account creation)
  • Checkout Start → Payment: Average 60–75%. Below 55% = checkout form friction (too many fields, confusing layout)
  • Payment → Purchase: Average 70–85%. Below 65% = trust or payment method problem (missing security signals, limited payment options)
  • End-to-end (Product → Purchase): Average 1.5–3%. Top quartile: 5%+

Frequently Asked Questions

What is a normal checkout drop-off rate?

Losing 60–80% of visitors between product page and purchase is typical. The key is understanding which step drops more than expected for your industry. Use the benchmarks above to identify outliers.

Where do most checkouts drop off?

The two biggest leak points: product page → add to cart (where 70–85% of visitors leave), and payment entry → purchase (where unexpected costs and trust concerns cause 25–40% to abandon). Your funnel data will show which applies to you.

How do I get this data from GA4?

GA4 Explore → Funnel Exploration. Steps: view_item → add_to_cart → begin_checkout → add_payment_info → purchase. Run for 30+ days, broken down by device type. Mobile drop-off is typically 15–20% higher at the payment step.

What fixes the biggest checkout drop-off?

Depends on the step. Product page: better images, clearer price/value, shipping cost visibility. Cart: guest checkout, show total cost. Checkout form: reduce fields, progress indicators. Payment: trust badges, more payment methods, BNPL options. See Cart Abandonment Rate for the full 12-fix breakdown.
