Owner Earnings (Buffett)

Warren Buffett introduced the concept of owner earnings as the earnings that genuinely belong to shareholders after the company has made all necessary investments to maintain and grow the business. It is calculated as reported earnings plus depreciation and amortization minus capex minus changes in working capital—essentially free cash flow to equity, but Buffett’s term emphasizes the owner-centric perspective. Owner earnings are what shareholders could theoretically withdraw while keeping the business on its current growth trajectory.

The formula

Owner earnings = Net income + Depreciation and amortization minus Capex minus Change in working capital

Alternatively: Net income + Depreciation minus Capex minus Increase in NWC

This is nearly identical to free cash flow to equity, but the framing is different: instead of “cash flow to equity holders,” Buffett calls it “earnings that belong to owners.”

The intuition

Reported earnings (net income) overstate what shareholders can actually claim because:

1. Depreciation is deducted but is not cash. Add it back.
2. Capex is cash spent but not deducted from earnings. Subtract it—it is a cash claim.
3. Working capital ties up cash. If receivables, inventory, or payables grow, that cash is tied up. Subtract the change.

The result is what the owner could actually extract from the business without harming it.

Why owner earnings is better than reported earnings

Earnings can be inflated by deferring capex. A company can cut maintenance capex to boost short-term earnings, but the business deteriorates. Owner earnings forces you to account for capex; cutting it is visible.

Works for all capital structures. Unlike net income (which is after interest), owner earnings work for both levered and unlevered companies. (If you want to compare to a levered peer, you’d need to subtract the tax-deductible interest separately.)

Emphasizes the owner perspective. It is conceptually clear: this is what you (the owner) can pull out of the business.

Example

A company reports:

• Net income: 100 million
• Depreciation and amortization: 30 million
• Capex: 35 million
• Increase in working capital: 5 million
• Owner earnings: 100 + 30 minus 35 minus 5 = 90 million

If the company has 100 million shares, owner earnings per share is 0.90. If a comparable earns 0.85 per share in owner earnings and trades at 20 dollars, this company at a 20 dollar price is trading at 22.2x owner earnings versus the comp at 23.5x—slightly cheaper.

Owner earnings vs. earnings per share

Reported EPS might be 1.00 (net income 100 million divided by 100 million shares), but owner earnings per share is 0.90. This is important: the company is generating less cash to owners than reported earnings suggest.

Conversely, a company with high depreciation (mature, capital-depreciated assets) might have low reported earnings but high owner earnings.

Owner earnings in valuation

Buffett’s approach. Buffett often values companies using owner earnings capitalization: take normalized owner earnings and divide by a reasonable capitalization rate (cost of equity). This is simpler than full DCF.

Owner value = Normalized owner earnings / Cost of equity

Or with growth:

Owner value = Owner earnings × (1 + growth) / (Cost of equity minus growth)

This is equivalent to a Gordon growth model applied to owner earnings.

Multiples approach. Apply an owner earnings multiple. If Berkshire owns a business earning 10 million in owner earnings and values it at 15x, the implied value is 150 million. This owner-earnings multiple is often similar to EV/EBITDA but more transparent about capital needs.

Normalizing owner earnings

Like normalized earnings, owner earnings should be normalized for cyclical effects and one-time items.

A company might have one year with very high capex (facility expansion) and low owner earnings. You wouldn’t use that year’s owner earnings to value the company; you’d normalize to a run-rate that includes normal capex.

Similarly, if the company suddenly reduced working capital one year (sold inventory, collected receivables), you’d normalize for more sustainable working capital needs.

Limitations

Capex can vary unpredictably. A company might have no major capex for five years, then suddenly need 50 million. Using average historical capex can be misleading.

Not the same as free cash flow. Owner earnings don’t account for debt service or tax effects. For a levered company, free cash flow to equity is more precise.

Working capital assumptions matter. If working capital is expected to grow significantly (rapid expansion), owner earnings overstates sustainable cash flow.

Buffett’s philosophy

Buffett’s emphasis on owner earnings reflects his long-term, intrinsic-value perspective. Rather than getting caught up in quarterly earnings surprises or accounting nuances, he asks: “What cash can I extract from this business indefinitely?” Owner earnings is his answer.

For mature, stable businesses with predictable capex and working capital needs, owner earnings is an excellent metric. For growth businesses or those with volatile capex, it requires more careful normalization.
