Custom price formula doesn’t affect subscriptions price

At single product page the customers can choose from a counter box the number of terabytes they want for the product they want to purchase. I take that number and with a custom function I add it at the products price. The price is saved correct at the tables of wordpress but at the subscription panel at /my-account/my-subscription/ the price still remains the same.
For example a customer buys a Product A with basic price 54 and choose 2 terabytes for that product, the price with the functions I added becomes 56 but at Subscriptions panel still remains 54.
Below is my code. Any suggestions would be appreciated. Thank you.

add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 10, 3 );
function add_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
     // get product id & price
    $product = wc_get_product( $product_id );
    $price = $product->get_price();
    // extra pack checkbox

    $tera = $_POST['number-1620393141673'];
    $cart_item_data['new_price'] = $price + $tera;
    
return $cart_item_data;
}

add_action( 'woocommerce_before_calculate_totals', 'before_calculate_totals', 10, 1 );
function before_calculate_totals( $cart_obj ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
return;
}
// Iterate through each cart item

foreach( $cart_obj->get_cart() as $key=>$value ) {
	if( isset( $value['new_price'] ) ) {
		$price = $value['new_price'];
		$value['data']->set_price( ( $price ) );
					}
			}
}
