How to Add a Shipping Calculator to Shopify Shopping Cart?

I will show you how to add a shipping calculator to your Shopify Shopping cart. This is a detailed guide with images so that non-tech store owners can execute on their own.

Still, HTML, CSS, JavaScript, and Liquid are all necessary. If you’re having trouble following the steps in the tutorial or want to set advanced shipping rules in Shopify, consider hiring a Shopify Expert.

What is Shipping rate calculator?

The shipping rates calculator is an advanced solution that lets customers estimate their shipping costs before they proceed to the checkout page.

Feature of Shipping rate calculator

On the cart page of your store, the shipping rates calculator displays your shipping rates. If a client is logged in, the calculator estimates shipping charges using the customer’s default shipping address. The shipping rates calculator accepts carrier-calculated, custom rates, or a combination of both rates.

• The shipping rate calculator only appears at on the cart page at www.your-shop-url.com/cart
• You can update your cart settings in the theme editor if you aren’t presently using a cart page.

• The rates are approximations in some cases because only the nation, province/state, and postal/zip code are provided for calculation rather than the whole address. At the time of checkout, you will be informed the actual pricing.
• It is possible to translate the displayed text.
• The currency description, such as CAD or USD, is included in the rates, which are formatted in your shop’s currency.
• If you know the basics of HTML, you can easily alter the calculator’s HTML.
• The calculator is built with an Underscore.js template and a JSON API. To get rates from Shopify, it uses Ajax.
• On the cart page, there is no similar API for calculating appropriate taxes. Taxes are calculated at the time of purchase.
• Currently, shipping calculators do not work in multiple currencies.

How to add a shipping rate calculator to your Shopify cart?

• In Shopify admin, go to Online Store > Themes.
• Choose your theme, and then click Actions > Edit code.

• In the Assets directory, click vendor.js. If your theme doesn’t have a vendor.js file, then click theme.js instead.
• Paste the code below to:
  • The bottom if you are using vendor.js
  • The top if you are using theme.js
