Introduction

The Fee & Discount Adjuster (formerly Custom Math) element is for businesses looking to adjust their pricing dynamically. 

It allows users to apply basic math operations (+, -, *, %) to either a group of products/services (sub-section total) or the entire calculator total. Ideal for adding fees, offering discounts, or converting yearly costs to monthly prices, it can be used with or without conditional logic. 

Whether adding a shipping fee or providing a 10% discount on a sub-section total, Fee & Discount Adjuster offers flexibility and precision. It’s perfect for scenarios like imposing setup fees or adjusting pricing based on user selections.

Shipping Cost - If you charge a base fee for shipping, you can use this feature to show that.

Setup Fees - impose a fixed dollar amount or percentage fee that is applicable to the total cost of the entire calculator.

Trigger Fee(s) - Add conditional logic to your Fee & Discount Adjuster element to trigger a charge.

Additional Information

Fee & Discount Adjuster feature can be set up to automatically add, subtract, multiply or divide a given value (not percentage). It does not have a toggle switch for the frontend, meaning the user cannot click anything to trigger Fee & Discount Adjuster.

Fee & Discount Adjuster cannot do variable math, commonly found in other complex cost calculator plugins. Keep in mind, that the Stylish Cost Calculator plugin was designed for ease of use and not for complex situations.

Fee & Discount Adjuster works at the subsection level, unless you activate the 'Apply Math to Calculator Total' option so that it applies to the calculator total.
