What is the checkout conversion rate?

Checkout conversion rate measures the percentage of users who complete a purchase after starting the checkout process. It’s a key ecommerce metric that tells you how well your checkout experience turns interested shoppers into paying customers.

It reflects how many people successfully complete checkout compared to those who begin it. A higher rate means your checkout flow is smooth, trusted, and user-friendly. A low rate may indicate friction, confusion, or unexpected costs during the final step.

Here’s how you can calculate checkout conversion rate:

(Number of Completed Purchases ÷ Number of Checkout Starts) × 100

For example, if 500 people start checkout and 350 complete their purchase, your checkout conversion rate is 70%.

Why is checkout conversion rate important in ecommerce?

It’s the final step in your funnel, where all your marketing, product pages, and cart optimization efforts come together. A poor checkout experience can undo all your hard work. By improving this rate, you increase revenue without increasing traffic.

Example of checkout conversion rate in action

An ecommerce store sees that 1,000 customers started checkout last month, but only 600 completed it. Their checkout conversion rate is 60%. By simplifying the form and adding one-click payment options, they increase that rate to 75% resulting in a significant revenue boost.

Driftcharge Tip

Many shoppers abandon their cart when forced to create an account. Let them complete their purchase without signing up, and give them the option to create an account after the order is placed. This keeps the process quick and user-friendly.
