Costco is home to the bulk deal and has built an ultra-loyal customer base through its membership-driven wholesale model. Over the years, it has managed to deliver strong revenue growth and consistent profitability. Costco’s scale allows for pricing power and wiggle room, making it resilient even in downturns.
Buying Costco shares remains a popular choice for investors due to its solid balance sheet and dividend growth. However, its high valuation means future performance depends on continued expansion and customer retention, so people need to keep stocking up on supplies for Costco shares to reach new heights.

Historical closes compared with the last close of $922.98
Forward annual dividend yield: 0.56% of stock value
Dividend payout ratio: 27.4% of net profits
Costco has recently paid out dividends equivalent to 0.53% of its share value annually.
Costco has paid out, on average, around 27.4% of recent net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 0.56% of the current stock value. This means that over a year, based on recent payouts (which are sadly no guarantee of future payouts), shareholders could enjoy a 0.56% return on their shares, in the form of dividend payments. In Costco's case, that would currently equate to about 4.92 per share.
While Costco's payout ratio might seem fairly standard, it's worth remembering that it may be investing much of the rest of its net profits in future growth.
Costco's most recent dividend payout was on 13 November 2025. To be eligible for the latest dividend you would need to have been a shareholder at 30 October 2025 (the "ex-dividend date").
Costco's dividend yield is perhaps best considered in relation to those of similar companies.
Costco's address is: 999 Lake Drive, Issaquah, WA, United States, 98027
Costco's shares were split on a 2:1 basis on 13 January 2000. So if you had owned 1 share the day before before the split, the next day you'd have owned 2 shares. This wouldn't directly have changed the overall worth of your Costco shares – just the quantity. However, indirectly, the new 50% lower share price could have impacted the market appetite for Costco shares which in turn could have impacted Costco's share price.

Yes. When you investing in a US stock, you need to complete a W8-BEN form to minimise your tax liability. Whether these are automatically handled for you depends on your broker, so it would be a good idea to check with them directly.
