LE Additive Variation Pricing

A WooCommerce plugin that lets you price each attribute value independently. The final price is calculated as:

Final Price = (Optional Base Price) + Sum of all selected attribute value prices

Enable it per product — existing WooCommerce variation pricing is completely untouched for all other products.

Features

• Per-product opt-in — enable additive pricing on individual variable products without affecting the rest of your store.
• Optional base price — set a fixed regular and/or sale base price added to every combination.
• Per-attribute-value pricing — assign a regular price and an optional sale price to every value of every variation attribute (e.g. Color: Red = $10, Blue = $15; Size: S = $0, XL = $5).
• Dynamic price display — the product page updates the displayed price in real time as the customer selects attributes, using the same currency format configured in WooCommerce.
• Price range on shop listings — shows a calculated min–max range (with sale markup when applicable) on archive/shop pages.
• Cart & order accuracy — the computed price is passed into the cart and saved to the order line item, so it survives product price changes after purchase.
• Sale price support — sale prices are optional at both the base level and the per-value level; strikethrough markup is applied automatically.

Data storage

All configuration is stored in a single post meta entry (_le_additive_pricing) on the product. The structure is:

{
  "enabled": true,
  "base_price": "20.00",
  "base_sale": "15.00",
  "prices": {
    "pa_color": {
      "blue":  { "regular": "10.00", "sale": "" },
      "red":   { "regular": "8.00",  "sale": "6.00" }
    },
    "pa_size": {
      "s":  { "regular": "0.00", "sale": "" },
      "xl": { "regular": "5.00", "sale": "4.00" }
    }
