Cart Price Rule — Percent of Product Price with Max Discount
============================================================

[](#cart-price-rule--percent-of-product-price-with-max-discount)

Overview
--------

[](#overview)

This extension introduces a new **Cart Price Rule action** in Magento:

**Percent of Product Price with Max Discount**

The rule allows store administrators to apply a percentage-based discount on product prices while limiting the total discount amount using a configurable **maximum discount value**.

This helps control promotional costs while still offering flexible percentage discounts.

---

How It Works
------------

[](#how-it-works)

When the rule is applied, the system calculates the discount amount based on:

> **The minimum value between:**
>
> - Percentage discount calculated from the quote total
> - Configured maximum discount amount

This ensures that the applied discount will **never exceed the defined maximum limit**.

---
