How to Display Custom Price fee in Sales Order View Page

You can learn how to add a custom amount in order total from here:

http://webkul.com/blog/add-custom-pricefee-order-total-magento2/

Now, if you want to display the custom price fee on the sales order view page, then you can follow the following process:

firstly, you need to create a sales_order_view.xml file in the folder:

app/code/Webkul/Test/view/frontend/layout

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

    <body>        
        <referenceContainer name="order_totals">
            <block class="Webkul\Test\Block\Sales\Order\Test" name="customfee"/>
        </referenceContainer>
    </body>
</page>

Now, you need to define a block file in which you need to define the init_totals() function, which adds a custom fee amount to your order view.

<?php
namespace Webkul\Test\Block\Sales\Order;

use Magento\Sales\Model\Order;

class Test extends \Magento\Framework\View\Element\Template
{
    /**
     * @var Order
     */
    protected $_order;
    /**
     * @var \Magento\Framework\DataObject
     */
    protected $_source;
    /**
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param array $data
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        array $data = []
    ) {
        parent::__construct($context, $data);
    }
    public function getSource()
    {
        return $this->_source;
    }

    public function displayFullSummary()
    {
        return true;
    }
    public function initTotals()
    {
        $parent = $this->getParentBlock();
        $this->_order = $parent->getOrder();
        $this->_source = $parent->getSource();
        $title = 'Custom Fee';
        $store = $this->getStore();
        if($this->_order->getCustomfee()!=0){
            $customAmount = new \Magento\Framework\DataObject(
                    [
                        'code' => 'customfee',
                        'strong' => false,
                        'value' => $this->_order->getCustomfee(),
                        'label' => __($title),
                    ]
                );
            $parent->addTotal($customAmount, 'customfee');
        }
        return $this;
    }
    /**
     * Get order store object
     *
     * @return \Magento\Store\Model\Store
     */
    public function getStore()
    {
        return $this->_order->getStore();
    }
    /**
     * @return Order
     */
    public function getOrder()
    {
        return $this->_order;
    }
    /**
     * @return array
     */
    public function getLabelProperties()
    {
        return $this->getParentBlock()->getLabelProperties();
    }
    /**
     * @return array
     */
    public function getValueProperties()
    {
        return $this->getParentBlock()->getValueProperties();
    }
}

Here, the init_totals() function adds the custom fee to your order by using the addTotal() method.

$customAmount is an object of dataObject that stores the label, code, and value for a custom fee.

‘customfee’ is the custom amount field name.

After this, your custom fee amount is visible on the customer’s order view page.
