Owner EarningsCopy Anchor Link

Owner earnings are warren-buffett's term for the cash a business actually produces for its owners in a year — as distinct from the GAAP earnings number, which can be pushed up or down by accounting choices. It is the input that sits upstream of dcf-valuation: before you can discount a stream of cash flows, you have to know what the cash flows really are.

The 1986 appendixCopy Anchor Link

Buffett lays out the concept most fully in the 1986 letter, in the context of the Scott Fetzer purchase, where a new owner's accounting charges made an identical business suddenly report less:

If we think through these questions, we can gain some insights about what may be called "owner earnings." These represent (a) reported earnings plus (b) depreciation, depletion, amortization, and certain other non-cash charges … less (c) the average annual amount of capitalized expenditures for plant and equipment, etc. that the business requires to fully maintain its long-term competitive position and its unit volume.

The equation is (a) + (b) − (c): reported earnings plus non-cash charges, minus the real capex needed to keep the business competitive. The crucial admission follows immediately — the term (c) is a judgment call, not a data point:

Our owner-earnings equation does not yield the deceptively precise figures provided by GAAP, since (c) must be a guess - and one sometimes very difficult to make. Despite this problem, we consider the owner earnings figure, not the GAAP figure, to be the relevant item for valuation purposes.

Buffett closes the section by invoking Keynes: "We agree with Keynes's observation: 'I would rather be vaguely right than precisely wrong.'"

The tell: when (c) exceeds (b)Copy Anchor Link

The whole point of the metric is that (b) (depreciation) is not always enough to cover (c) (real maintenance capex). When a business must spend more than it depreciates just to hold its ground, GAAP overstates the cash available to owners — and Buffett notes the oil industry of the 1980s was a conspicuous example, where spending only depreciation would have "guaranteed their shrinkage in real terms." The distinction is the same one that later became famous as maintenance vs. growth capex.

Owner earnings as intrinsic value's raw materialCopy Anchor Link

The 1993 letter ties the concept to value itself, defining intrinsic value as "a present-value estimate of the cash that can be taken out of a business during its remaining life." Owner earnings are that cash. And the 2000 letter closes the loop on what the other, more popular metrics are worth:

Common yardsticks such as dividend yield, the ratio of price to earnings or to book value, and even growth rates have nothing to do with valuation except to the extent they provide clues to the amount and timing of cash flows into and from the business. Indeed, growth can destroy value if it requires cash inputs in the early years.

The 2014 letter states the operational corollary — that the object is to build owner earnings, not merely book them: "our main focus is to build operating earnings", and the best of Berkshire's manufacturing businesses are "measured by earnings on unleveraged net tangible assets."

Where it fitsCopy Anchor Link

Owner earnings is the correction term between accounting-quality and valuation. It is the reason dcf-valuation and terminal-value are built on free cash flow rather than net income, and it is the practical bridge from reported numbers to intrinsic-value.
