php - WooCommerce display saved amount on product page

one text

Solution:

You don't see the currency simply because you get it but you don't print it.

Also you can use the wc_price() function to print the formatted price (with currency) according to your shop settings.

You can optimize your code like this:

add_action( 'woocommerce_single_product_summary', 'usteda_popust', 11 );
function usteda_popust() {

    global $product;
    
    if ( $product->is_type('simple') || $product->is_type('external') || $product->is_type('grouped') ) {
        if ( $product->get_sale_price() ) {
            $amount_saved = $product->get_regular_price() - $product->get_sale_price();
            ?>
            <p style="font-size:18px;color:red;">Ušteda: <?php echo wc_price( $amount_saved ) ?></p>
            <?php
        }
    }
}

The code has been tested and works. Add it to your active theme's functions.php.

Here is the result:
