Hello,

Remove the previous code and add the following PHP code in the function.php of the child theme. This code is for both simple products and variable products.

// For product variations
 add_filter( 'woocommerce_available_variation', 'custom_variation_price_saving_percentage', 10, 3 ); function custom_variation_price_saving_percentage( $data, $product, $variation ) { $active_price = $data['display_price']; $regular_price = $data['display_regular_price']; if( $active_price !== $regular_price ) { $saving_percentage = round( 100 - ( $active_price / $regular_price * 100 ), 1 ) . '%'; $data['price_html'] .= sprintf( __('<p class="saved-sale">Save: %s</p>', 'woocommerce' ), $saving_percentage ); } return $data; }

// For simple products 
add_filter( 'woocommerce_get_price_html', 'change_displayed_sale_price_html', 10, 2 ); function change_displayed_sale_price_html( $price, $product ) { // Only on sale products on frontend and excluding min/max price on variable products if( $product->is_on_sale() && ! is_admin() && $product->is_type('simple') ){ // Get product prices $regular_price = (float) $product->get_regular_price(); // Regular price $sale_price = (float) $product->get_price(); // Active price (the "Sale price" when on-sale) // "Saving Percentage" calculation and formatting $precision = 1; // Max number of decimals $saving_percentage = round( 100 - ( $sale_price / $regular_price * 100 ), $precision ) . '%'; // Append to the formated html price $price .= sprintf( __('<p class="saved-sale">Save: %s</p>', 'woocommerce' ), $saving_percentage ); } return $price; }

Best Regards.
