Linking Products & Variants to Calculators

Written By Floris de Vries

Last updated 2 days ago

The Link calculator forms page is used to connect calculators to Shopify product variants. This determines which calculator is shown on the product page and allows you to manage calculator assignments at scale.

Calculators are always assigned at variant level.
If a product has only one variant, the calculator is automatically applied to that variant.

Each variant can be linked to one calculator at a time.

How linking works

  • Calculators are assigned per variant

  • If a calculator is linked, it will be displayed on the product page for that variant

  • If no calculator is linked, the product behaves normally without a calculator

  • Changes apply immediately after saving

This setup ensures precise control over pricing and logic per variant.

Product list overview

The table shows all products in your store, including their variants.

For each row, you can see:

  • Product name

  • Calculator form – the calculator currently linked to the variant

You can link, change, or remove calculators directly from this list.

Linking a calculator to a variant

To link a calculator:

  1. Locate the product or variant in the list

  2. Open the Calculator form dropdown

  3. Select the calculator you want to assign

Once selected, the calculator becomes active for that specific variant.

For products with only one variant, this effectively applies the calculator to the product.

Removing a calculator

To remove a calculator from a variant:

  1. Open the Calculator form dropdown

  2. Click the remove (×) icon

The variant will no longer display a calculator.

Variant-level behavior

When a product has multiple variants:

  • Each variant can have its own calculator

  • The active calculator updates automatically when the customer switches variants

  • This allows different pricing logic, fields, or formulas per variant

This makes variant-level calculator assignment ideal for products with size-, material-, or option-based pricing differences.

Refresh product data

Use Refresh product data to sync the latest products and variants from Shopify.

This is useful when:

  • New products or variants were added

  • Product or variant data was updated

  • Variants are missing from the list

💡 Tip:
Always refresh product data after large catalog changes to ensure all variants are available.
