If You'd Invested $1,000 in Costco Stock 20 Years Ago, Here's How Much You'd Have Today |

Costco Wholesale (COST +0.76%) stock didn’t have a great year in 2025, losing 6% of its value. But over many decades, Costco has outperformed the market and rewarded shareholders. It’s reliable for sales growth and high profits, and its model continues to stand out and attract new members. If you’d invested $1,000 20 years ago and just held on, you’d have a lot more today.

The winning Costco model

Costco’s rock-bottom prices appeal to any shopper at any time, but the company’s bare-bones warehouses, bulk packaging, and low prices are even more attractive when customers are pinching pennies. That’s why the company typically grows in any kind of market, but reports some of its best performance under pressure.

In the current environment, it has consistently reported high-single-digit sales growth, including 8.2% in the 2026 fiscal first quarter (ended Nov. 23, 2025). It continues to add millions of new members and upgrade many of them to executive status, which implies greater loyalty.

The core model hasn’t changed in decades, and if you’d recognized the potential and invested 20 years ago, you’d have a lot more money today. If you’d invested $1,000 in Costco stock, you’d have $27,600 today, including dividends. Contrast that with $7,900 invested in the S&P 500.
