How to Display Total Discount Savings in the WooCommerce Cart and Checkout

You can display total discount savings in the WooCommerce cart and checkout by looping through cart items to calculate the difference between regular and sale prices, adding any coupon discount, and echoing the combined total as a new row in the totals table.

Why Show Total Savings to Customers

• Seeing a concrete “You Saved $24.50” figure reinforces the value of a purchase decision
• It combines both sale-price discounts and coupon discounts into one clear, motivating number
• Highlighting savings at the point of checkout can help reduce cart abandonment

Step 1: Calculate and Display the Savings Row

/**
 * Show total savings from sale prices and coupons in cart/checkout totals
 * Add to your child theme's functions.php
 */
add_action( 'woocommerce_cart_totals_after_order_total', 'display_total_savings_row' );
add_action( 'woocommerce_review_order_after_order_total', 'display_total_savings_row' );

function display_total_savings_row() {
    $sale_savings = 0;

    foreach ( WC()->cart->get_cart() as $cart_item ) {
        $product = $cart_item['data'];
        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 ) * (int) $cart_item['quantity'];
        }
    }

    $coupon_savings = WC()->cart->get_discount_total();
    $total_savings  = $sale_savings + $coupon_savings;

    if ( $total_savings > 0 ) {
        echo '<tr><th>You Saved</th><td>' . wc_price( $total_savings ) . '</td></tr>';
    }
}

Troubleshooting

The Savings Row Doesn’t Appear

Confirm at least one item in the cart is actually on sale or a coupon is applied — the function intentionally hides the row entirely when there’s nothing to show, to avoid an empty “$0.00 saved” message.

The Total Doesn’t Match What You Expect

This calculation combines sale-price savings with coupon discounts into a single number. If you want them shown separately, split the calculation into two variables and echo two distinct rows instead of combining them.

Conclusion

A loop through cart items combined with the cart’s coupon discount total is enough to display total discount savings in the WooCommerce cart and checkout, giving shoppers a clear, motivating summary of what they’ve saved. Test with both sale-priced items and coupons applied together to confirm the combined total calculates correctly.
