Number Calculation Conditions

This article explains how to use number calculation conditions to create powerful, flexible discounts. Calculations let you define a number dynamically and store it in a variable for future comparisons.

Example Use Cases

• “Apply a discount if quantity of Product A is 3× the quantity of Product B”
• “Calculate total quantity of products in Collection X and store it for later”
• “Create tiered discounts based on the sum of specific quantities”

What Are Calculations?

Calculations are a type of condition that compute a number and assign it to a variable. You can then:

• Reference that variable later in your logic
• Use arithmetic (+, −, ×, ÷)
• Work with dynamic values like product quantities, cart totals, or other calculations

How to Use It

1. Add a Calculation

• In the Logic Builder, click Add Criteria
• Select Calculate a Number

2. Configure the Expression

• Use math operators to combine terms
• Example:

→ Quantity of Product A × 3 = quantity_times_three

• This assigns a variable called quantity_times_three

3. Use the Result

• Add a Compare Numbers condition
• Left side: Quantity of Product B
• Right side: the variable quantity_times_three
• Now the logic says: “Only apply the discount if quantity of B equals 3× A”

Notes

• You can combine constants, quantities, and even other calculated values
• Calculations don’t do anything on their own—they must be used later in a condition
• Use clear variable names so the logic is easy to follow
