How to read this chart

Every point shows what the estimate would have been on that day using only what had been published by then. Nothing here uses information that wasn't available at the time.

So the filing-based lines step when a report publishes, not when the quarter it describes ended — typically five to nine weeks later. That is why the two book lines run parallel rather than touching: they are equal only at a quarter end, and by the time that quarter's filing is public, prices have already moved.

Clicking a legend entry adds or removes a line, and the scale follows what's shown — hiding the book lines gives price and intrinsic value the full height of the chart.

$39.8B annualized pretax operating earnings ($19.8B YTD × 2.02) × 10, excluding insurance investment income

Why 10×?

Buffett has written in shareholder letters that he values businesses at 10–15× pretax earnings, with higher-quality businesses at the upper end. At Berkshire's ~21% effective tax rate, 10× pretax is equivalent to roughly 13× after-tax. Berkshire's mix of capital-intensive segments (BNSF, BHE) and higher-return franchises (insurance) has to be blended into a single figure; many analysts of comparable conglomerates use 16–18×.

This is a what-if. The published estimate uses 15×.

Value them at 10× 12× 15× 18×
Less: liabilities charged −$303.46B

The full liability side as filed. Income taxes and 100% of insurance float are deducted from intrinsic value — the rest is already accounted for elsewhere, as noted per line. Float is the one line where two conventions are both defensible, so it is the one line you can change; the others are not adjustable, for the reasons given on each.

Liabilities Amount Treatment
Insurance float (policyholder reserves) $213.29B 100% charged — the conservative treatment Changeable — see the note below.
Notes payable and other borrowings $43.30B Not deducted — earnings are already after interest
Other liabilities (payables, etc.) $53.41B Not deducted — working capital inside the businesses
Insurance and Other liabilities $310.00B

Total liabilities $512.89B Shown for reference, not subtracted in full
How insurance float is treated

Float — the policyholder reserves above — is the money Berkshire holds between collecting premiums and paying claims. As long as underwriting roughly breaks even and float is stable or growing, it behaves like low- or no-cost leverage. Underwriting has been profitable, so this float has cost less than nothing.

Float is being charged at 100% here — more conservative than the published estimate, which charges none of it. That treats the whole balance as a debt coming due, lowering intrinsic value by $213.29B.

The argument against doing so: float funds the investments — the equity portfolio, T-bills, bonds and cash — that are counted at market in the asset rows above, and the income those investments throw off has already been excluded from the operating-earnings multiple for exactly that reason. Subtracting the principal on top of that charges for the same dollars a second time.

Both conventions are defensible. Switching between them picks a reading; it does not correct an error.

Charge against value 0% (none) 25% 50% 75% 100%

0% treats float as permanent capital — the published model. 100% treats it as a debt coming due. The steps between are a sensitivity ladder, not an estimate: no published convention puts a figure on how much of float is really a liability.

Intrinsic Value (total)
$820.75B = $383 per B share
Operating earnings are the pretax earnings of the operating segments from the 2026-06-30 10-Q XBRL filing, annualized to a full-year run-rate, excluding the insurance investments segment — that income comes from the cash, T-bills and securities already counted at market above. Deferred income taxes and 100% of insurance float are deducted; operating-business debt is not (see below).

How intrinsic value is calculated Method, assumptions, and the GAAP equity bridge.

Two columns, following the approach Buffett has described in the shareholder letters. First, the investments: the 13F equities and Japan stakes at live market prices, plus cash, Treasury bills, bonds and any stake the 13F doesn't already carry. Second, the operating businesses — insurance underwriting, BNSF, Berkshire Hathaway Energy, manufacturing, service and retailing — valued at 10× their annualized pretax earnings. Deferred income taxes are then subtracted.

What this deliberately does not do:

  • It does not capitalize investment income. The insurance investments segment is excluded from the earnings that get the multiple, because the cash, bonds and securities producing that income are already counted at market in the first column. Counting both would pay twice for the same dollars.
  • It does not deduct operating-business debt. Segment pretax earnings are already after interest expense, so capitalizing them values the equity in those businesses net of borrowings.

You are viewing a what-if. The published model does not deduct insurance float, for the reason given above; this view charges 100% of it, which is the more conservative alternative rather than a correction. Change it back.

Operating earnings are the pretax earnings of the operating segments from the 2026-06-30 10-Q XBRL filing, annualized to a full-year run-rate, excluding the insurance investments segment — that income comes from the cash, T-bills and securities already counted at market above. Deferred income taxes and 100% of insurance float are deducted; operating-business debt is not (see below).
GAAP equity bridge (fallback method)

Book equity plus the market uplift on tracked public holdings. A GAAP anchor that understates the operating businesses, shown for comparison.

Berkshire carries listed equities at fair value, so the 2026-06-30 balance sheet already marks them to that date's prices. Only the move since then is added here — adding the positions themselves would count them twice. Operating businesses stay at book, which is why this sits well below the sum-of-parts estimate: it is a floor, not a valuation.

Not included in the figure above, and not part of the sum-of-parts estimate either — that model deliberately neither adds a float premium nor deducts float, on the grounds that the investments float funds are already counted at market and the income they produce is excluded from the earnings multiple. This line is an assumption about franchise value, shown for reference only.

Holdings Foreign-listed shares fall outside 13F reporting. Share counts come from Japan's large-shareholding reports (大量保有報告書), filed with the FSA by National Indemnity Company — a wholly-owned Berkshire subsidiary — and published through EDINET. Each row in the asset list links to its filing.
What That Misses A report is required on crossing 5% and on each change of about 1% thereafter. A stake below 5%, or a move smaller than the threshold, is never filed — so this is a floor on what is knowable, not a complete record of what Berkshire owns in Japan.
