Magento 2: Get Product Stock Quantity and Other Stock Information

This article shows how to get stock quantity (qty) of a product in Magento 2. We can also fetch other stock information like minimum quantity (min_qty), minimum sale quantity (min_sale_qty), maximum sale quantity (max_sale_qty), see if a product is in stock (is_in_stock), etc.

We will be using Magento 2’s Service Layer for this task. Use of Service Layer is highly encouraged by Magento.

Below is a block class of my custom module (Chapagain_HelloWorld). I have injected object of \Magento\CatalogInventory\Model\Stock\StockItemRepository class in the constructor of my module’s block class.

app/code/Chapagain/HelloWorld/Block/HelloWorld.php

<?php
namespace Chapagain\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{	
	protected $_stockItemRepository;
		
	public function __construct(
		\Magento\Backend\Block\Template\Context $context,		
		\Magento\CatalogInventory\Model\Stock\StockItemRepository $stockItemRepository,
		array $data = []
	)
	{
		$this->_stockItemRepository = $stockItemRepository;
		parent::__construct($context, $data);
	}
	
	public function getStockItem($productId)
	{
		return $this->_stockItemRepository->get($productId);
	}
}
?>

Now, we load the product by id and sku in template file.

$id = YOUR_PRODUCT_ID;
$productStock = $block->getStockItem(1225);
//print_r($productStock->getData()); 
echo $productStock->getQty(); echo '<br />';
echo $productStock->getMinQty(); echo '<br />';
echo $productStock->getMinSaleQty(); echo '<br />';
echo $productStock->getMaxSaleQty(); echo '<br />';
echo $productStock->getIsInStock(); echo '<br />';

Using Object Manager

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();		

$appState = $objectManager->get('\Magento\Framework\App\State');
$appState->setAreaCode('frontend');

$stockItem = $objectManager->get('\Magento\CatalogInventory\Model\Stock\StockItemRepository');

$id = 1; // YOUR PRODUCT ID

$productStock = $stockItem->get($id);

var_dump($productStock->getData());

Hope this helps. Thanks.
