The Magento 2 price format at checkout can sometimes be confusing in case of any additional charges such as VAT, surcharge, payment fee, etc.
Earlier, I had offered a php-based solution to get formatted price with currency in Magento 2.
Today, I am here with a JS-based solution for the same!
The default Magento 2 will not bother about displaying the currency symbol or decimal values but simply display the numbers. It will look something like this:
So if you would want to display $20.99, instead it will show 2099. The meaning will entirely change in such cases.

However, after applying the solution to set price format using Javascript in Magento 2, it will display the additional charges as below:

Check the solution for the same:
Method to Set Price Format Using Javascript in Magento 2:
define( [ 'ko', 'jquery', 'Magento_Checkout/js/view/summary/abstract-total', 'Magento_Checkout/js/model/quote', 'Magento_Catalog/js/price-utils' ], function (ko,$,Component,quote,priceUtils) { "use strict"; return Component.extend({ getPrice : function () { var price = 20; // You can giv date return priceUtils.formatPrice(price, quote.getBasePriceFormat()); } }); } );
That’s it.
