Pricing power is a company's ability to raise prices without losing customers to competitors. It is the practical consequence of a durable advantage, and because it shows up directly in margins, it is the easiest moat evidence to verify from published numbers.
Why it is the test that matters
Warren Buffett's formulation is that the single most important decision in evaluating a business is pricing power, and that if you have to hold a prayer session before raising prices by a tenth of a cent, you have a terrible business. The appeal of the test is that it collapses a lot of qualitative moat discussion into something observable.
A company with a genuine moat can pass on cost increases. One without a moat absorbs them, and you see the result in the margin line.
How to see it in the numbers
Track gross margin across an inflationary stretch. Input costs rose for everyone during 2021 and 2022, which makes that period an unusually clean natural experiment. A company whose gross margin held or expanded was passing costs through. One whose margin compressed was eating them.
Then separate price from volume. Companies often disclose revenue growth split into pricing and volume in the management discussion, or on earnings calls. Growth that is mostly price, with volume flat or rising, is the signature of pricing power. Growth that is all volume at falling prices is the opposite.
Where it comes from
Pricing power is a symptom rather than a cause, and the underlying causes are the familiar moat sources. Switching costs make leaving expensive enough that a price rise is tolerated. A network effect means the alternative is worse regardless of price. A brand that carries identity rather than function lets a company charge more for the same physical thing.
The most durable form is when the product is a small share of the customer's total cost but critical to the outcome. Nobody changes supplier over a rounding error on something that must not fail.
Where the test misleads
A company can raise prices for a while without having pricing power, by drawing down goodwill it spent years accumulating. Price rises that outrun the value delivered show up later as customer losses, so check volumes and retention alongside the margin. In a subscription business, net revenue retention above 100% while prices are rising is the confirmation you want.
The other failure is confusing a temporary shortage for a durable advantage. Anyone can raise prices when supply is short. The question is what happens when it is not.
