Price by Formula Calculator for WooCommerce 4.0.5

Price by Formula Calculator for WooCommerce is a specialized extension that allows store owners to calculate product prices dynamically based on custom mathematical formulas.1 While standard WooCommerce treats a product as a single unit with a fixed price, this plugin lets you create products where the final cost depends on user-provided data (like dimensions, weight, or custom choices).

🚀 Key Capabilities (2026 Standards)

In 2026, this plugin has evolved to handle almost any "Build-to-Order" or "Made-to-Measure" scenario.

1. Complex Mathematical Logic2

Basic Operators: Use $+$, $-$, $*$, and $/$ to build your logic.

Advanced Functions: Supports $min()$, $max()$, $round()$, $ceil()$, and $floor()$. For example, you can set a minimum "base charge" of $50 regardless of how small the measurements are using a max(50, formula) logic.3

Conditional Formulas (IF/ELSE): You can change the entire formula based on a user's selection.4 Example: Use Formula A for "Premium Wood" and Formula B for "Standard Pine."

2. Extensive Field Options

The plugin typically offers 16+ field types to collect user data, including:

Number inputs (for Length, Width, Height)5

Dropdown select boxes6

Radio buttons and Checkboxes7

Text areas for custom instructions8

3. Dynamic Real-Time Updates

As the customer types in their dimensions or selects options, the price on the product page updates instantly.9 This "live quote" experience is proven to increase conversion rates for custom services.

🛠 Common Use Cases

Industry

How it's Used

Home Decor

Selling blinds, carpets, or glass by the square foot/meter.

⚙️ How to Set It Up

Create a Rule: Go to WooCommerce > Price Formula and add a new rule.10

Add Fields: Create the input fields you need (e.g., a "Length" field and a "Width" field).11 Assign them shortnames like [L] and [W].

Write the Formula: In the formula box, enter your calculation.12

Example: ([L] * [W] * 0.15) + 20 (Where 0.15 is the price per unit and 20 is a flat shipping fee).

Assign to Products: Apply the rule to specific products or entire categories.13

⚖️ Pricing & Availability (2026)

Official Version: Usually available on the WooCommerce Marketplace for approx. $79/year.14
