This extension allows setting the maximum discount amount (upper limit) for a percentage-based cart rule.

Community: 2.3, 2.4Enterprise: 2.3, 2.4
Set a maximum discount amount (upper limit) for percentage-based cart price rules in Magento 2. Run promotions like "Get 10% OFF, up to $50" — a must-have for controlled promotional campaigns.
The Problem
Magento 2 does not provide a built-in way to cap the discount amount on percentage-based cart rules. Without a ceiling, large orders can generate unexpectedly high discounts — eating into margins and making budget-friendly promotions impossible to run safely.
The Solution
Discount Limiter adds a Maximum Discount Amount field to every percentage-based cart price rule. Set an upper limit once, and Magento automatically caps the discount — no custom code, no margin surprises.
Key Features
Feature Highlights
Limit Discount Amount on Percentage Rules
Define the maximum discount a percentage-based cart rule can apply. The extension adds a dedicated Maximum Discount Amount field to the cart rule edit page in the Magento admin. Once configured, the discount is automatically capped at checkout — regardless of cart total.
Common Promotion Scenarios
- Flat 10% OFF on the entire cart, capped at $50 maximum discount
- 10% OFF for first-time orders, up to $25 maximum discount
- 15% OFF during seasonal sales, limited to $100 maximum discount
- 20% welcome discount for new customers, capped at $30
Easy Admin Configuration
Configure global settings from Admin > Marketing > Discount Limiter > Manage Settings. Enable or disable the extension per store view and set the maximum discount amount directly within each cart price rule — no additional pages or complex setup required.
