What is Magento 2 out of stock threshold?


Out-of-Stock Threshold is a default Magento 2 configuration that determines the stock level at which a product is regarded as out of stock and needs to be ordered again. It subtracts from the stock’s Salable Quantity and the backorders depend on it.

The formula for the Salable Quantity is (Quantity – (Out-of-Stock Threshold)).

There are 2 statuses of backorders impacted by of stock threshold:

  • Backorders disabled: Entering a positive value over 0, such as 5 or 25. Customers can place product quantity lesser than the quantity in the inventory.
  • Backorders enabled: Enter a negative threshold for the maximum quantity of allowed backorders, such as -5 or -25. A positive value is ignored and treated like 0. A value of 0 acts as infinite stock.

Step by step to configure Magento 2 out of stock threshold

To set the desired Magento 2 out of stock threshold, you can follow the below-detailed guide:

Step 1: Go to Out-of-Stock Threshold configuration

  • Set for general products: Go to Stores > Settings > Configuration. Then, expand Catalog in the left panel and select inventory.
  • Set for specific products: Go to Catalog > Products. Then, open the product you want to customize in edit mode, and click Advanced Inventory under the Quantity configuration.

Step 2: Set up the related configurations


Backorders: allow customers to continue ordering while the product is out of stock. The order’s processing status remains unchanged, the payments are promptly authorized and captured, and the shipment is on-hold until stock is available. Choose one of 3 options:

  • No Backorders: Does not accept backorders when the product is out of stock.
  • Allow Qty Below 0: Accepts backorders when the quantity falls below zero.
  • Allow Qty Below 0 and Notify Customer: Accepts backorders when the quantity falls below zero but notifies customers that orders can still be placed.

Out-of-Stock Threshold: 

  • With Backorders disabled, enter a positive amount.
  • With Backorders enabled, entering 0 allows for infinite backorders.
  • With Backorders enabled, we recommend entering a negative amount. The amount is added to the Salable Quantity. For example, enter -50 to allow orders up to this amount.
Example Salable Quantity after backorders enabled and Out-of-Stock Threshold value is -50
