Costco: the membership fee is the business, the merchandise is the proof

$914.80Current price
$1,010Price target
+10.4%Implied upside
92%Membership renewal rate

Costco earns most of its profit from membership fees and sells goods at close to cost to keep members renewing. That design makes earnings steadier than any ordinary retailer and lets the company reinvest savings in lower prices.

We rate the stock a Buy with a target of $1,010. The multiple is high, but the quality of the revenue and the room to open more warehouses abroad justify it.

Company overview

Costco operates membership warehouses that sell a limited range of goods in bulk under tight markup rules. A small number of items per category means huge volume per item, which gives it purchasing leverage few rivals can match.

Roughly half of operating profit comes from membership fees, paid up front and renewed annually.

Other considerations

ValuationThe shares trade at a multiple of earnings far above other retailers, so any slowdown in comparable sales is punished.High
Tariffs and sourcingA large share of non-food goods are imported; tariffs raise costs that the company has chosen not to pass on quickly.Medium
Labor costsAbove-market wages raise the cost base each contract cycle, though they lower turnover.Medium

Investment thesis and considerations

The thesis is that the market treats Costco as a grocer when it behaves like a subscription business with a store attached.

1. Fees drive predictable profit

Renewal rates above 90% and periodic fee increases turn most operating profit into a recurring stream.

The last fee increase took the standard membership to a new price, and renewal rates held up. Because fees are paid in advance and the cost of serving a member is mostly already covered by merchandise margin, each increase flows mostly to profit. We expect a further increase around 2029 on the historical cycle of five and a half years, and we model it at the low end of the past range.

2. International warehouses are early

Newer markets have a fraction of the warehouses per person of the U.S. and mature quickly.

Warehouses opened abroad reach sales volumes similar to U.S. ones within a few years, and executive commentary points to a faster opening pace in Asia and Europe. We estimate that international markets contribute under a fifth of profit today and could near a third by the end of the decade. The market appears to model slow, mature-market growth for the whole company.

3. Price discipline is the moat

A fixed markup cap keeps prices low, which builds trust that competitors cannot buy.

The company limits its markup on most goods and returns savings to members. The result is a loyalty effect that shows up in renewals and in the willingness of suppliers to give volume terms. The risk to this view is a competitor matching the model, which would require years of lower profit; we see no sign of it. A pullback toward $820 would strengthen the case for adding.

Bull case

A fee increase lands with unchanged renewal rates.
Warehouse openings in Asia and Europe accelerate.
E-commerce and retail media add margin without hurting prices.

Bear case

Comparable sales slow and the multiple compresses.
Tariff costs squeeze merchandise margin.
Renewal rates slip after a fee increase.

Key assumptions

  • Comparable sales grow 5.5% a year excluding fuel; about 25 net new warehouses a year.
  • Membership fee increase in FY29 at the low end of the historical range.
  • Merchandise gross margin steady within 20 basis points.

Discounted cash flow$910 to $1,160

The discounted cash flow carries half of the weight. Because the multiple is the contested point, the comps method uses the best-in-class retailers rather than the grocery sector. The unit economics method values the fee stream directly.
