Calculate and display deposit in cart total en check-out total – Woocommerce

I changed my whole code to this and this is working. This wil show a deposit in the cart summary under the price and a total deposit if it are more items under the subtotal.

Also in the cart total summary it is displaying the depost total of all items and in checkout too.

add_filter( 'woocommerce_cart_item_price', 'add_deposit_value_to_cart_single' , 10, 3 );
add_filter( 'woocommerce_cart_item_subtotal', 'add_deposit_value_to_cart_total', 10, 3 );


/**
* Statiegeld toevoegen aan single product
*/
function add_deposit_value_to_cart_single( $product_price, $values, $cart_item_key ) {
    // Get your custom fields data
    $custom_field1 = get_post_meta( $values['product_id'], '_aantal_statiegeld', true );
    //$statiegeld = get_field( "statiegeld", $values['product_id']);
    $dep_total = $custom_field1;
    
    if( ! empty( $dep_total ) )
        return $product_price . '<br /><small class="deposit_label">' .  sprintf( __( 'statiegeld %s' ), wc_price( $dep_total ) ) . '</small>';
    
    return $product_price;
}

    $dep_total = $custom_field1 * $values['quantity'];
    
    if( ! empty( $dep_total ) )
        return $product_price . '<br /><small class="deposit_label">' .  sprintf( __( 'statiegeld totaal %s' ), wc_price( $dep_total ) ) . '</small>';
    
    return $product_price;
}
