Need help with Cart Shipping Calculator?

Most issues can be fixed in a couple of quick checks. Start with the setup steps below, and if things still don’t look right, email us and we’ll help.

Quick setup check

Open Online Store → Themes, then click Edit theme on your current theme.
Turn on the Cart Shipping Calculator under App embeds in the theme editor.
Open your storefront cart and confirm live rates appear (Geo-IP or after entering a postal/ZIP code).

Troubleshooting

Ensure at least one item is added to the cart before testing. The Cart Shipping Calculator only activates when a cart exists.
Ensure the embed is enabled in the Theme Editor, then refresh the cart page.
Test in a fresh incognito window to rule out caching.
Verify active shipping zones/rates in Settings → Shipping and Delivery.
Most setup issues can be resolved by following the steps above or reviewing Shopify’s help article linked here: Extend your theme with apps (Shopify Help).

If a shipping rate doesn’t appear for your region, it’s usually due to how your Shopify shipping zones are configured. The app uses Shopify’s own /cart/shipping_rates.json endpoint, so all rates come directly from your store’s settings. If your rates are set up correctly but still don’t appear, contact us and we’ll take a look.
