Please try with below code in controller :

protected $_checkoutSession;

protected $quoteRepository;

public function __construct(
    \Magento\Checkout\Model\Session $checkoutSession,
    \Magento\Quote\Api\CartRepositoryInterface $quoteRepository
) {
    $this->_checkoutSession = $checkoutSession;
    $this->quoteRepository = $quoteRepository;

public function execute()
    $quote = $this->_checkoutSession->getQuote();

    $grandTotal = "200"; // Set your grand total

    echo $quote->getGrandTotal();
