Show Discount Savings Message in WooCommerce Cart & Checkout — WordPress Code Snippet - WPFolks — A community for the people who build on WordPress

Displays a “You are saving” row in the WooCommerce cart and checkout totals table, combining coupon discounts and sale price savings into a single amount. Encourages customers to complete their purchase by showing the total value they’re getting.

add_action( 'woocommerce_cart_totals_after_order_total', function() {

    if ( ! WC()->cart ) {
        return;
    }

    $discount     = (float) WC()->cart->get_discount_total();
    $sale_savings = 0;

    foreach ( WC()->cart->get_cart() as $cart_item ) {

        $product  = $cart_item['data'];
        $quantity = (int) $cart_item['quantity'];

        if ( $product->is_on_sale() ) {

            $regular_price = (float) $product->get_regular_price();
            $sale_price    = (float) $product->get_sale_price();

            $sale_savings += ( $regular_price - $sale_price ) * $quantity;
        }
    }

    $total_savings = $discount + $sale_savings;

    if ( $total_savings > 0 ) {

        echo '<tr class="order-total savings-total">';
        echo '<th>' . esc_html__( 'You are saving', 'woocommerce' ) . '</th>';
        echo '<td><strong>' . wp_kses_post( wc_price( $total_savings ) ) . '</strong></td>';
