Have you ever faced a challenge while trying to display custom prices for products in Magento 2? If so, you're not alone. Whether it's managing tier prices or integrating unique pricing logic, this can be a tricky area to navigate. Magento's robust, flexible platform is a double-edged sword—it offers extensive customization options, but also introduces complexity.
In this article, we'll delve into how you can effectively override product prices, including tier prices, in Magento 2. We'll cover the steps to ensure your custom price logic is implemented correctly across all relevant parts of your store. By the end, you'll have a comprehensive understanding of how to achieve custom pricing in Magento 2, ensuring a smooth shopping experience for your customers.
Magento 2 provides various pricing mechanisms, ranging from simple product prices to complex tier pricing rules. The final price of a product is not always straightforward; it can be influenced by discounts, special prices, tier prices, group prices, and more.
Tier pricing allows store owners to offer bulk discounts to customers purchasing large quantities of a product. While effective for promotions, it adds another layer of complexity when customizing product prices.
Magento uses several methods to calculate and display prices. Among the most important are getPrice and getFinalPrice. The getPrice method retrieves the base price of the product, whereas getFinalPrice calculates the price after considering various rules, including tier pricing. For a thorough price override, focusing on the getFinalPrice method is crucial.

To override the product price, including tier pricing, you need to target the correct methods in Magento. Below, we outline the critical steps to achieve this through an example setup.
The getFinalPrice method is pivotal as it aggregates all price rules, presenting the final price of the product. Overriding this method ensures that your custom price logic is applied comprehensively.
Create a Plugin for getFinalPrice Method
First, you need to define a plugin in your di.xml file:
di.xml
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager:etc/config.xsd"> <type name="Magento\Catalog\Model\Product"> <plugin name="custom_price_plugin" type="Vendor\Module\Plugin\Product" /> </type> </config>
Implement the afterGetFinalPrice Method
Next, create the Product.php file to implement the custom logic:
Product.php
namespace Vendor\Module\Plugin; use Magento\Catalog\Model\Product; class Product { public function afterGetFinalPrice($subject, $result) { // Custom price logic $customPrice = $result + 10; // Example adjustment return $customPrice; } }
This code ensures your custom price is applied after the final price calculation, considering any tier prices.
To reflect this custom pricing on the frontend, you might need to override certain Magento templates or classes responsible for showing the price.
Modify FinalPriceBox Rendering
Override the FinalPriceBox class to ensure the custom price is displayed correctly:
namespace Vendor\Module\Override\Catalog\Pricing\Render; use Magento\Catalog\Pricing\Render\FinalPriceBox as OriginalFinalPriceBox; class FinalPriceBox extends OriginalFinalPriceBox { protected function wrapResult($html) { // Override logic as needed return $html; } }
Update di.xml to Apply Custom Render Class
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager:etc/config.xsd"> <type name="Magento\Catalog\Pricing\Render\FinalPriceBox"> <plugin name="custom_finalpricebox_plugin" type="Vendor\Module\Override\Catalog\Pricing\Render\FinalPriceBox" /> </type> </config>
After implementing your changes, it's essential to flush the Magento cache. This step ensures that your modifications are applied and visible across your store.
php bin/magento cache:flush
If the custom price isn't reflecting as expected, or if issues persist, consider debugging the getFinalPrice method in more detail:
// Add debugging code inside your custom plugin public function afterGetFinalPrice($subject, $result) { // Example debugging: Log the original and modified prices $originalPrice = $result; $customPrice = $result + 10; // Example adjustment $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/custom_price.log'); $logger = new \Zend\Log\Logger(); $logger->addWriter($writer); $logger->info('Original Price: ' . $originalPrice); $logger->info('Custom Price: ' . $customPrice); return $customPrice; }
Monitor the log to gain insights into any issues or discrepancies.
Customizing product prices, including tier prices, in Magento 2 requires a deep understanding of the platform's pricing mechanisms. By strategically overriding the getFinalPrice method and ensuring the correct rendering is implemented, you can effectively manage custom pricing logic across your store. This approach not only provides flexibility but also ensures a cohesive shopping experience for your customers.
Lastly, always remember to test thoroughly and clear the cache to see your changes in action.
To override product prices in Magento 2, you should target the getFinalPrice method using a plugin. This method takes all pricing rules into account, ensuring that your custom price logic is applied correctly.
Ensure you're overriding the correct methods and flushing the cache after making changes. Debugging the getFinalPrice method can also help identify any issues.
Yes, within the afterGetFinalPrice method, you can add conditions to apply custom pricing logic to specific products based on attributes or other criteria.

Double-check your di.xml and ensure your custom plugin is properly configured. Verify that you flushed the cache and consider adding debugging logs to troubleshoot.
Tier pricing adds complexity as it involves bulk discount rules. By targeting the getFinalPrice method, which aggregates all pricing rules, you can ensure your custom pricing logic works alongside tier pricing.
With these insights and steps, you're well-equipped to implement and troubleshoot custom pricing in Magento 2 effectively.
