Overview
Flat Rate Shipping is a shipping method where you charge a single fixed price for any order, regardless of weight, size, or distance. It's set up under Settings > Shipping and Delivery in Shopify as a shipping rate for a zone.
Flat rate is the simplest shipping model for customers to understand — they know the cost upfront, which removes the surprise-shipping friction that causes abandoned carts. It's ideal when your products have similar shipping costs or you want to simplify the checkout experience.
The trade-off is margin. If your actual shipping costs vary widely, a flat rate means you overcharge some customers and undercharge others. Many brands pair flat rate with a free-shipping threshold to lift AOV, or use calculated shipping when costs vary too much.
Why Flat Rate Shipping Matters for Shopify Merchants
- 1
Simple for Shoppers
A known shipping cost upfront removes surprise-shipping abandonment.

Easy to Set Up
One rate per zone is the simplest shipping model to configure.

Predictable Costs
Customers and you both know the shipping cost before checkout.
- 4
Pairs With Free Shipping
Add a free-shipping threshold above the flat rate to lift AOV.
- 5
Good for Similar Products
Works well when your items have similar weights and shipping costs.
Using Flat Rate Shipping Without Losing Margin
- 1
Know your average cost
Calculate your average shipping cost per order before setting the flat rate.
- 2
Set it to cover cost
Price the flat rate at or slightly above your average so it doesn't erode margin.
- 3
Add a free-shipping threshold
Offer free shipping above a cart value to lift AOV and offset the flat rate.
- 4
Use zones if costs vary
Set different flat rates per shipping zone if distant orders cost more.
- 5
Switch to calculated if variance is high
If shipping costs vary widely, calculated shipping protects margin better.
