With the following code, I have got the correct displayed shipping method cost based on a subsidy (see this thread): add_filter( 'woocommerce_cart_shipping_method_full_label', 'custom_shipping_method_full_label', 10, 2 ); function custom_shipping_method_full_label( $label, $method ) { if ( !in_array( $method->get_method_id(), array( 'free_shipping', 'local_pickup' ), true ) && 0 < $method->cost ) { $label = $method->get_label(); // Get shipping label without cost $new_cost = $method->cost - get_total_subsidies( WC()->cart->get_cart() ); if ( $new_cost > 0 ) { $method->cost = $new_cost; $label .= ': ' . wc_price( $new_cost ); } else { $method->cost = 0; $label .= ': ' .' <span class="free-cost">' . __('Free!', 'woocommerce').'</span>'; } } return $label; } But it doesn't get extended to the totals calculations, taking into account the original shipping method cost. I need the new cost to be the current cost for totals calculations from cart and checkout pages.

To handle the shipping costs and totals recalculations (+ handle those shipping methods display), you need to replace your current code with the following: // Utility function: Reset shipping taxes function zero_taxes( $tax ) { return 0; } // Set new shipping rate costs add_action('woocommerce_package_rates', 'custom_shipping_rates_cost', 10, 2); function custom_shipping_rates_cost( $rates, $package ) { $total_subsidies = get_total_subsidies( $package['contents'] ); if ( ! $total_subsidies ) { return $rates; } // Loop through shipping rates foreach ($rates as $rate_key => $rate) { if( ! in_array( $rate->method_id, array( 'free_shipping', 'local_pickup' ), true ) && $rate->cost > 0 ) { $new_cost = $rate->cost - $total_subsidies; if ( $new_cost > 0 ) { $rates[$rate_key]->cost = $new_cost; // Set the new cost } else { $rates[$rate_key]->cost = 0; // Null the cost $rates[$rate_key]->taxes = array_map('zero_taxes', $rate->taxes); // Null shipping costs taxes $rates[$rate_key]->label .= ': <span class="free-cost">' . __('Free!', 'woocommerce') . '</span>'; // Custom displayed label } } } return $rates; } Code goes in functions.php file of your child theme (or in a plugin). It should work. Important: Empty your cart to refresh the shipping methods cached data. Related: Display total subsidy amount based on WooCommerce cart items shipping class and quantity
