Magento using regular price instead of the special price when calculation tier price type discount

[mohammedTBB]

Preconditions and environment

• Magento version 2.4.6-p4
• Php: 8.1

Steps to reproduce

1- Create a simple producto 2- add a special price lower than the regular price 3- add a tier price Discount 4- check the product in the frontend

Example: product: 24-MB01 regular price: 255.36 special price: 202.84 Customer group price (tier price) Quantity: 2 , Price: Discount 25%

Expected result

Special price should be used to calculate the tier price and the final price.

Example: Sepcial price - tier price discount = final price 202.84 - 25% = 152,13$

Actual result

Regular price is ued to calculate the tier price and the final price.

Example: Regular price - tier price discount = final price 255.36 - 25% = 191,52$

Additional information

I think the tier price should be calculated based on the minimum price which in this case the special price.

Hi @mohammedTBB,

Thanks for your reporting and collaboration.

As Per the Magento devdocs it looks like and expected behaviour of magento

Final Price will calculated as below.Regular price = Base price which we have created for a product.

Kindly let us know if we are missing anything.

Thanks.

Hi @engcom-Bravo Based on the NOTE mentioned in the devdocs The final product price is calculated as the minimum relevant price

Should not the tier price be calculated based on the special price and not the original price because it is the minimum price in this case?

Thanks.

Hi @mohammedTBB,

Thanks for your update.

As per the mentioned document final price will calculate based on the regular price(which we have created for the product) not on the special price and it is an expected behaviour of magento.

Please have a look on Magento devdocs https://experienceleague.adobe.com/en/docs/commerce-admin/catalog/products/pricing/product-price-special#testing

Thanks.
