COST vs PG: How Costco Wholesale and Procter & Gamble Compare (2026)
Last updated July 2026
Short answer
COST is the larger of the two ($430.88B market cap): the incumbent the market prices for continued execution (42.90x forward earnings, beta 0.87). PG is the smaller challenger ($337.32B), cheaper on forward earnings (19.50x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
COST vs PG: the tie-breaker metrics
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.
| Metric | COST | PG | What it tells you |
|---|---|---|---|
| Market cap | $430.88B | $337.32B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 42.90 | 19.50 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 48.80 | 21.21 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.87 | 0.38 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 51% of range | 24% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 26.06 | 6.28 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: PG 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.
Before you buy: how COST and PG affect your concentration
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 PG 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 PG 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.

What does Costco Wholesale (COST) do?
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.
What does Procter & Gamble (PG) do?
Procter & Gamble is one of the world's largest consumer-products companies, selling everyday household and personal-care brands used by billions of people. Its portfolio is organized into segments spanning fabric and home care (Tide, Ariel, Downy, Dawn, Febreze), baby, feminine, and family care (Pampers, Always, Bounty, Charmin), beauty (Olay, Pantene, Head & Shoulders, SK-II), grooming (Gillette, Venus), and health care (Crest, Oral-B, Vicks, Metamucil). P&G makes money selling these branded products through retailers, e-commerce, and other channels worldwide, relying on scale, marketing, and continual product innovation to command premium pricing and shelf space. The company deliberately pruned its portfolio over the past decade to focus on a smaller set of large, profitable, daily-use categories. Founded in 1837 and headquartered in Cincinnati, Ohio, P&G is a classic defensive blue chip and a Dividend King, prized for steady cash flow, pricing power, and an exceptionally long record of dividend increases.
COST vs PG: how do they differ?
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.
- PG drivers: Brand strength and pricing power; Defensive, recurring demand.
Which fits which kind of investor
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 PG, p&G's mature categories grow slowly, so organic growth depends on modest pricing and volume gains; in a low-inflation environment, raising prices further is harder and volumes can soften if shoppers trade down to private-label alternatives.
COST or PG: which should you pick?
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; PG 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 PG guides.
COST vs PG: the full fundamentals
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.
PG. P&G is a high-margin, cash-rich consumer-staples leader that commands a premium valuation for its brand strength, defensiveness, and unmatched dividend record. The financial profile is steady rather than fast-growing: modest organic growth, reliable margins, and consistent capital return funded by very strong free cash flow.
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; PG shows revenue (ttm) ~$84 billion, operating margin ~24%, net margin ~18%, free cash flow ~$15+ billion annually.
The bottom line: COST vs PG
COST and PG 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 PG exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between COST and PG?
+
Costco Wholesale operates a membership-based warehouse club chain. Procter & Gamble is one of the world's largest consumer-products companies, selling everyday household and personal-care brands used by billions of people. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is COST or PG the better stock?
+
Neither is universally better. COST is the larger incumbent; PG is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, COST or PG?
+
On forward P/E (as of July 2026), COST trades at 42.90x and PG at 19.50x, so PG is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both COST and PG?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of COST vs PG?
+
COST: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. Any consumer slowdown or competitive pressure from BJ's, Sam's Club, or Amazon would compress the multiple. PG: P&G's mature categories grow slowly, so organic growth depends on modest pricing and volume gains; in a low-inflation environment, raising prices further is harder and volumes can soften if shoppers trade down to private-label alternatives. A large share of sales comes from outside the US, exposing earnings to a strong dollar and emerging-market currency swings. Input-cost inflation (commodities, energy, transportation) can pressure margins. Private-label competition and shifting retailer dynamics, including the bargaining power of large retailers, are persistent threats. The defensive profile also means the stock can lag sharply in strong bull markets, and its premium valuation leaves little room for execution missteps.
