Description

Price by Formula Calculator for WooCommerce is a pricing calculator plugin that adds custom product options and works out prices using formulas you define. You can sell products by units such as kg, meter, or square meter, and apply the same rule to multiple products or categories.

Key Features

  • Custom pricing formulas – You build a price calculator by writing your own formulas with basic math operators such as +, -, *, and /.
  • Sixteen option fields – You can create up to sixteen fields for product options, including text areas, select boxes, radio buttons, checkboxes, and multi-select boxes.
  • Sell by measurement – Products can be sold by units of measurement such as kg, meter, square meter, or cubic yard.
  • Conditional formula groups – You can change the formula based on what the customer enters or on the result of another formula.
  • Rules for many products – A single rule can be applied to multiple products or categories instead of building a separate calculator for each one.
  • Show calculations on page – You can display the measurement calculations and resulting prices on the product page for shoppers to see.
  • Details on cart and orders – The chosen option details appear on the cart, checkout, and order detail pages.
  • Import and export rules – Pricing rules you create can be exported and imported, which helps when moving setups between stores.

Who Is It For

This plugin is for WooCommerce store owners who sell products or services priced by measurements or custom inputs, such as items sold by area, length, volume, or weight, or offerings like installment plans and service quotes. It suits shops that need several product options feeding into a price calculation without building a separate calculator for every item.
