• Magento 2 shipping cost as percentage of order

Unlike default Magento shipping options, which don’t allow percentage-based rules, this module introduces a simple yet powerful way to align shipping costs with your business model. For example, if you set a 5% shipping rule, an order of $100 will generate a $5 shipping fee, while a $500 order will automatically calculate $25. Key Features: Set shipping costs as a percentage of the order subtotal Flexible configuration — define minimum and maximum shipping charges Apply to specific customer groups or store views Combine with free shipping rules for large orders Works seamlessly with discounts and tax-inclusive orders Compatible with Magento 2.4.x and PHP 8.2+ Why Use Percentage-Based Shipping? Flat rate.

• Define percentage shipping rules per website with optional minimum and maximum fees.
• Layer multiple tiers so high-value carts pay the exact percentage you expect.
• Automatically reduce charges when shoppers hit your free-shipping thresholds.
• Works alongside Magento flat-rate and table-rate methods without conflicts.
• Fully compatible with Magento 2.4.x Open Source and Adobe Commerce.
