COST vs HD: How Costco Wholesale and The Home Depot Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: HD is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. COST and HD share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined COST and HD exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

Costco Wholesale operates a membership-based warehouse club chain. Members pay an annual fee (currently $65 for basic Gold Star, $130 for Executive) for access to Costco warehouses, where they can buy products at lower markups than traditional retailers. Costco operates approximately 900 warehouses globally, with the largest concentration in the United States plus meaningful presence in Canada, Mexico, the UK, Japan, South Korea, Taiwan, Australia, and other markets.

The Home Depot, Inc. is the world's largest home improvement retailer, operating approximately 2,300 stores across the United States, Canada, and other locations in North America. The company sells building materials, home improvement products, lawn and garden supplies, and provides installation and tool-rental services to two main customer groups: do-it-yourself homeowners (DIY) and professional contractors (Pros). Revenue is generated almost entirely through retail store sales and, increasingly, through digital channels (online sales reached 15.9% of total revenue in fiscal 2025) and through its specialty trade distribution arm, SRS Distribution, which serves Pros directly with roofing, landscaping, pool supplies, and now drywall and steel framing products following the September 2025 acquisition of GMS Inc. The company earns a gross margin of roughly 33% and an operating margin in the low-to-mid teens, with strong free cash flow that funds a steadily growing dividend (156 consecutive quarterly payments as of early 2026) and periodic share repurchases.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• COST drivers: Membership fee growth; International expansion.
• HD drivers: Pro contractor ecosystem buildout; Pent-up housing demand and a potential mortgage rate cycle turn.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. For HD, the most direct risk is a prolonged freeze in the US housing market: low inventory, elevated mortgage rates, and high home prices have kept transaction volumes near multi-decade lows, directly suppressing demand for the large remodeling projects that drive Home Depot's highest-ticket sales.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick COST if you believe its drivers more; HD if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the COST and HD guides.

COST. Costco trades at one of the highest P/E ratios in retail, reflecting the durable membership model, consistent same-store sales growth, and the long runway for international expansion. The premium is also driven by Costco being widely viewed as a quality compounder in retail. The valuation has compressed historically only during severe market drawdowns.

HD. Home Depot grew total revenue 3.2% in fiscal 2025, but most of that growth came from the SRS and GMS acquisitions rather than organic comparable-store performance, which was essentially flat at +0.3%. Profitability softened modestly as acquisition-related costs, higher debt service, and integration expenses weighed on margins and pushed ROIC down from 31.3% to approximately 25.7%. The stock's trailing P/E of roughly 23x sits near its 10-year historical average and above the peer group, reflecting investor confidence in the long-term Pro strategy but leaving limited cushion if the housing market remains depressed longer than expected.

Headline figures (approximate, early 2026): COST shows revenue (ttm) ~$260 billion, operating margin ~3.5% (low, by design; membership fees are the profit lever), net income (ttm) ~$7.5 billion, eps (ttm) ~$17.00; HD shows revenue (fiscal 2025, ended feb 1, 2026) ~$164.7 billion, net earnings (fiscal 2025) ~$14.2 billion, diluted eps (fiscal 2025) $14.23 (adjusted: $14.69), gross margin (fiscal 2026 guidance) ~33.1%.

COST and HD are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined COST and HD exposure against your real portfolio. It is not an investment adviser.
