Advanced Quantity-based Shipping Rules

The Each Quantity Rule section allows you to set up shipping rates that apply per a defined number of items in the cart. Instead of a flat cost, you can configure WooCommerce to calculate shipping dynamically based on quantity.

For example:

• Rule: 1,5,0 → means $1 shipping for every 5 items, starting from quantity 0.
• If the customer orders 10 items, the shipping = $2.

This gives you a way to tie shipping costs directly to product quantities.

Why use the quantity rules?

• Fair cost allocation: Customers pay proportionally for larger orders.
• Protect margins: Cover packaging and handling costs for bulk quantities.
• Flexibility: Define different rules per quantity step, rather than a flat rate for all.
• Encourage bulk sales: You can keep per-quantity rates small to promote bigger purchases.

Example 1: Apply $1 charges for each 5 quantity from the 1st quantity

Example 2: If the cart quantity is over 20, then wants to apply $5 for each additional quantity.

Expected outcome

When configured, WooCommerce will automatically calculate shipping based on the quantity steps you define. For example, if you set $1 for every 5 items, then:

• Cart with 5 items = $1 shipping.
• Cart with 10 items = $2 shipping.
• Cart with 15 items = $3 shipping.

This ensures your shipping fees scale fairly with order size, giving customers transparent pricing while giving store owners better cost control.
