Amazon.com Inc. vs Costco Wholesale
AMZN and COST, both consumer, compared on the same figures computed the same way.
On our discounted cash flow model, Amazon.com Inc. looks the cheaper of the two, trading 12 percentage points further below its estimated fair value than Costco Wholesale. That is a statement about price against one model, not a forecast, and most of a DCF's output sits in a terminal value nobody can actually forecast.
Costco Wholesale scores higher on our moat model (80 against 80). A moat is a structural reason competitors cannot take the profits away, and over a long holding period it matters more than any single quarter's numbers.
AMZN trades at 43.7 times earnings against COST's 50.0. A lower multiple is not automatically the better deal: on a cyclical business the low P/E arrives at the top of the cycle, right before earnings fall.
The honest answer to "which is better" is that it depends on what you are buying them for, and neither this page nor any screen can make that judgement for you. What it can do is show you the same figures for both, computed the same way, so the comparison is fair.
| Metric | AMZN | COST |
|---|---|---|
| Share price | $186.40 | $900.00 |
| Market cap | $1.94T | $400.00B |
| P/E ratio | 43.7 | 50.0 |
| DCF fair value | $198.00 | $850.00 |
| Upside to fair value | +6.2% | -5.6% |
| Moat score | 80/100 | 80/100 |
| Dividend yield | — | 0.50% |
| Return on equity | 21.0% | 30.0% |
| Overall rating | 68/100, Buy | 70/100, Strong Buy |
Gold marks the more favourable figure on rows where “better” has an agreed direction. It is a signpost, not a verdict. A lower P/E can be a value trap; a higher yield can be a dividend about to be cut.
