Adding Custom Fees Using WooCommerce Hooks

WooCommerce provides the woocommerce_cart_calculate_fees hook, allowing developers to apply extra fees dynamically.

Steps to Add a Fixed Fee in WooCommerce

Open your WordPress theme’s functions.php file.
Insert the following PHP snippet:

function tutorialswebsite_apply_custom_fee() {
    if (is_admin() && !defined('DOING_AJAX')) return;
    
    $fee_amount = 5; // Set additional charge amount
    WC()->cart->add_fee(__('Service Fee', 'woocommerce'), $fee_amount);
}
add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_custom_fee');

function tutorialswebsite_apply_custom_fee() {

if (is_admin() && !defined('DOING_AJAX')) return;

$fee_amount = 5; // Set additional charge amount

WC()->cart->add_fee(__('Service Fee', 'woocommerce'), $fee_amount);

}

add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_custom_fee');

Save the file and check the checkout page for the additional fee.

Adding Extra Charges for Cash on Delivery (COD)

If you want to apply an additional fee when customers select Cash on Delivery (COD), use this modified function:

function tutorialswebsite_apply_cod_fee( $cart ) {
    if (is_admin() && !defined('DOING_AJAX')) return;

    if (isset(WC()->session)) {
        $chosen_payment = WC()->session->get('chosen_payment_method');

        if ($chosen_payment === 'cod') {
            $fee_amount = 10;
            $cart->add_fee(__('COD Handling Fee', 'woocommerce'), $fee_amount);
        }
    }
}
add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_cod_fee');


function refresh_checkout_on_payment_change() {
    ?>
    <script type="text/javascript">
        jQuery(function($){
            $(document.body).on('change', 'input[name="payment_method"]', function() {
                $('body').trigger('update_checkout');
            });
        });
    </script>
    <?php
}
add_action('wp_footer', 'refresh_checkout_on_payment_change');

function tutorialswebsite_apply_cod_fee( $cart ) {

if (is_admin() && !defined('DOING_AJAX')) return;

if (isset(WC()->session)) {

$chosen_payment = WC()->session->get('chosen_payment_method');

if ($chosen_payment === 'cod') {

$fee_amount = 10;

$cart->add_fee(__('COD Handling Fee', 'woocommerce'), $fee_amount);

}

add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_cod_fee');

function refresh_checkout_on_payment_change() {

jQuery(function($){

$(document.body).on('change', 'input[name="payment_method"]', function() {

$('body').trigger('update_checkout');

});

</script>

<?php

}

add_action('wp_footer', 'refresh_checkout_on_payment_change');

How It Works:

Checks the selected payment method.
If COD is selected, a ₹10 handling fee is applied.
The fee only appears when COD is chosen, keeping checkout fees dynamic.

Adding Additional Fees Based on Payment Method and Cart Total

You may need to charge fees differently based on the selected payment method and the cart total. The following snippet handles that:

function tutorialswebsite_apply_payment_method_fees( $cart ) {
    if (is_admin() && !defined('DOING_AJAX')) return;
    
    $selected_payment = WC()->session->get('chosen_payment_method');
    $cart_total = WC()->cart->cart_contents_total;
    
    if ($selected_payment === 'cod' && $cart_total < 250) {
        WC()->cart->add_fee(__('COD Fee (Orders Below 250)', 'woocommerce'), 10);
    } elseif ($selected_payment === 'paypal' && $cart_total > 300) {
        WC()->cart->add_fee(__('PayPal Processing Fee (Orders Above 300)', 'woocommerce'), 5);
    }
}
add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_payment_method_fees');

function refresh_checkout_on_payment_change() {
    ?>
    <script type="text/javascript">
        jQuery(function($){
            $(document.body).on('change', 'input[name="payment_method"]', function() {
                $('body').trigger('update_checkout');
            });
        });
    </script>
    <?php
}
add_action('wp_footer', 'refresh_checkout_on_payment_change');

function tutorialswebsite_apply_payment_method_fees( $cart ) {

if (is_admin() && !defined('DOING_AJAX')) return;

$selected_payment = WC()->session->get('chosen_payment_method');

$cart_total = WC()->cart->cart_contents_total;

if ($selected_payment === 'cod' && $cart_total < 250) {

WC()->cart->add_fee(__('COD Fee (Orders Below 250)', 'woocommerce'), 10);

} elseif ($selected_payment === 'paypal' && $cart_total > 300) {

WC()->cart->add_fee(__('PayPal Processing Fee (Orders Above 300)', 'woocommerce'), 5);

}

add_action('woocommerce_cart_calculate_fees', 'tutorialswebsite_apply_payment_method_fees');

function refresh_checkout_on_payment_change() {

jQuery(function($){

$(document.body).on('change', 'input[name="payment_method"]', function() {

$('body').trigger('update_checkout');

});

</script>

<?php

}

add_action('wp_footer', 'refresh_checkout_on_payment_change');

How It Works:

If COD is selected and the cart total is less than ₹250, a ₹10 fee is applied.
If PayPal is selected and the cart total exceeds ₹300, a ₹5 fee is added.
Ensures that fees are added dynamically based on cart conditions
