Costco currently trades at a trailing P/E of 50x while sales and EPS growth are expected to decelerate below 10% by 2027. PEG ratios of 4–6x and fair value estimates of $450–$565 imply a substantial overvaluation given potential headwinds from weaker U.S. consumer spending.
Costco’s trailing P/E ratio stands at 50x, significantly above historical averages and peer valuations. This high multiple suggests investors are pricing in robust growth that may not materialize as the company’s expansion slows.
Analysts forecast Costco’s sales and EPS growth to decelerate below 10% by 2027, down from current rates near double digits. This slowdown reflects market saturation in key regions and potential margin pressures from rising operating costs.
A PEG ratio of 4–6x underpins a fair value range of $450–$565, nearly half the current market level. This valuation considers both growth forecasts and Costco’s strong cash position of over $20 billion.
Weaker U.S. consumer spending, potential recessionary trends, and intensified competitive discounting could further pressure Costco’s top line. Investors should weigh these macroeconomic headwinds against the retailer’s membership-based model and bulk-pricing advantages.
