This article explains how to view total order costs on admin orders in Magento 1.
When placing an order in your Magento admin panel, you may want to review the order total, including the shipping costs, before placing the order.
Once you’ve selected the shipping method for the order, click the ‘Save Shipping Details’ button, this will add the selected method to the Order Totals section.
You can change shipping options without any impact on the final order. Simply select another option and click ‘Save Shipping Details’ again. The option selected when the “Submit Order” button is clicked, is the option used on the final order.
