Warren Buffett Daughter Net Worth: Who’s Who and How to Verify

When people search for 'Warren Buffett daughter net worth,' they almost always mean Susan Alice Buffett, known as Susie, born in 1953 and the only daughter among Warren Buffett's three children. She is not a billionaire in her own right by any documented public estimate, but she is meaningfully wealthy through a combination of Berkshire Hathaway share gifts from her father, her seat on Berkshire's board of directors (added in November 2021), and her leadership of the Sherwood Foundation, an Omaha-based private foundation to which Warren Buffett has donated hundreds of millions of dollars in Berkshire Class B shares over the years. Most credible estimates place her personal net worth somewhere in the range of $100 million to $500 million, though that figure is genuinely difficult to pin down precisely because a significant portion of the assets flowing to her name pass through charitable trust and foundation structures rather than direct personal holdings.

Which Buffett daughter are you actually looking for?

Warren Buffett has exactly one daughter: Susan Alice Buffett, universally called Susie. His other two children are sons, Howard Graham Buffett and Peter Andrew Buffett. This matters because searches sometimes confuse the family members, and because Howard and Peter each lead their own foundations (the Howard G. Buffett Foundation and the NoVo Foundation, respectively), which generates separate financial documentation that occasionally surfaces in searches about 'Buffett family wealth.' If you landed here looking for one of the sons, the financial structure is similar but the figures and roles differ. This article focuses specifically on Susie Buffett, since she is the only daughter and the most common intended subject of this search.

There is also occasional confusion with Susan Thompson Buffett, Susie's mother and Warren's first wife, who passed away in 2004. The Susan Thompson Buffett Foundation is a major philanthropic entity in reproductive health funding, but it is a separate organization from the Sherwood Foundation that Susie chairs. Keeping those two foundations distinct is essential when you are trying to evaluate Susie's personal financial profile.

Why 'net worth' gets complicated when trusts and charity are involved

For most public figures, net worth is a relatively straightforward aggregation of documented assets minus liabilities. For someone like Susie Buffett, who sits at the intersection of one of the world's largest private fortunes, a multi-decade philanthropic giving program, and a private foundation she chairs, the picture is genuinely murkier. A large share of the Berkshire stock her father has transferred is directed to the Sherwood Foundation rather than to her personally. Those assets belong to the foundation, a separate legal entity, not to Susie individually. When a website lists the Sherwood Foundation's total assets (which have at times exceeded several hundred million dollars based on IRS Form 990-PF filings) and calls that 'Susie Buffett's net worth,' it is conflating two different things.

Personal net worth would include her direct Berkshire Hathaway share holdings, any real estate or other personal assets, board compensation from Berkshire, and income from the Sherwood Foundation in the form of officer compensation (which is disclosed on Form 990-PF). Foundation assets, by contrast, are restricted for charitable purposes and cannot be treated as personal wealth. This is a common analytical error on low-credibility aggregator sites, and it can make estimates swing dramatically depending on whether the author bothered to make that distinction.

What public records actually document

There are three categories of primary source documentation that give us the clearest window into Susie Buffett's financial ties to the Berkshire Hathaway ecosystem.

SEC filings and Berkshire proxy statements

Berkshire Hathaway's annual proxy statement, filed with the SEC, discloses director compensation and beneficial ownership for board members. Since Susie joined the Berkshire board in November 2021, she has appeared in these filings. The proxy discloses share ownership above specified thresholds, director fees, and equity awards. These are verifiable, date-stamped primary documents you can pull directly from SEC EDGAR by searching for Berkshire Hathaway (ticker BRK) proxy filings (form DEF 14A). Separately, Warren Buffett's Schedule 13D and 13D/A filings on EDGAR document each time he donates Berkshire Class B shares to foundations including the Sherwood Foundation, with share counts and dates recorded. These filings let you trace the mechanics of each transfer even if they don't tell you Susie's personal balance sheet directly.

IRS Form 990-PF filings for the Sherwood Foundation

The Sherwood Foundation files IRS Form 990-PF annually as a private foundation. These filings are publicly available through ProPublica's Nonprofit Explorer and directly via Guidestar (now Candid). Each 990-PF shows the foundation's total assets, investment income, charitable distributions, and officer compensation. Susie Buffett is listed as Chairman. The officer compensation line is the one figure that directly reflects money flowing to her personally from the foundation. The foundation's total assets and grant distributions are entity-level figures, not personal income. ProPublica's Nonprofit Explorer has digitized filings processed from 2012 onward, making it a practical starting point for anyone trying to trace multi-year trends in foundation size and Susie's role.

Berkshire share donation announcements

Warren Buffett has made annual donation announcements since 2006, committing Berkshire shares to multiple foundations. In a 2025 report, a single round of donations totaled $6 billion in Berkshire shares split across several charitable recipients, including the Sherwood Foundation alongside the Howard G. Buffett Foundation and the NoVo Foundation (Peter's). Berkshire press releases and SEC filings both document these transfers. Each donation to the Sherwood Foundation increases the foundation's asset base, which indirectly reflects the scale of resources Susie oversees, though again, not her personal net worth.

Estimated net worth ranges and how they're built

Because Susie Buffett does not run a public company, has not disclosed personal financial statements, and is not tracked by Bloomberg's Billionaires Index or Forbes's real-time wealth tracker (both of which focus on holdings-based valuations for individuals with disclosed stakes above certain thresholds), any net worth figure for her is an estimate assembled from partial data. Here is how a reasonable estimate is typically constructed:

1. Direct Berkshire share holdings: Check the Berkshire proxy (DEF 14A) for any disclosed beneficial ownership. Even small percentages of Berkshire's market cap translate to significant dollar figures given the company's scale.
2. Board compensation: Berkshire director fees and any equity-linked compensation are disclosed in the proxy. This is modest relative to the family's broader wealth but is a documented, personal income line.
3. Officer compensation from Sherwood Foundation: Pulled from the 990-PF, this is the clearest personal income figure tied to her foundation leadership role.
4. Inferred transfers: If SEC filings show X number of Class B shares donated to Sherwood over time, and separately Susie received personal gifts of shares (documented in proxy beneficial ownership), you can apply the current Berkshire Class B share price to estimate a holdings value.
5. Adjustments for philanthropy: Shares donated to Sherwood are subtracted from personal holdings, since those assets belong to the foundation.

Using this framework, credible estimates for Susie Buffett's personal net worth tend to cluster in the $100 million to $500 million range as of mid-2026. Some aggregator sites claim figures outside this range, but those estimates typically either fold in Sherwood Foundation assets incorrectly or rely on speculation about undisclosed personal transfers. Until a primary document surfaces that changes the picture, the honest answer is that her personal wealth is substantial but not billionaire-scale, and the precise figure carries real uncertainty. If you came here specifically looking for the Walmart heiress net worth, the same idea applies: credible numbers depend on clearly separating personal assets from foundations and trusts personal net worth.

Her career, business roles, and known assets

Susie Buffett's professional life is centered on philanthropy rather than business operations. The Sherwood Foundation, which she chairs, focuses on education, early childhood development, and poverty reduction primarily in Nebraska. Separately, she is associated with the Buffett Early Childhood Fund. Neither entity generates personal revenue for her beyond officer compensation. Her most significant new business role is her seat on the Berkshire Hathaway board of directors, which she joined in November 2021. Board membership at Berkshire is not a ceremonial role at a small company: Berkshire's market capitalization regularly exceeds $800 billion, making it one of the largest companies in the world. Even modest director compensation at that scale, combined with any Berkshire share holdings tied to her directorship, represents meaningful wealth by most standards.

Her known asset base is anchored in Berkshire Hathaway Class A or Class B shares, consistent with how Warren Buffett has structured wealth transfers to all three of his children. Real estate and other personal assets are not publicly documented. There is no record of her holding significant equity stakes in private companies outside the Berkshire ecosystem. Her wealth profile is simpler in structure than, say, a tech heir with diversified private holdings, which actually makes it easier to verify from primary documents.

How to verify estimates yourself

If you want to cross-check any figure you have seen for Susie Buffett's net worth, here is a practical methodology:

The key verification habit is to note the as-of date for any estimate you find. Forbes explicitly states as-of dates on net worth figures for a reason: Berkshire's share price moves significantly, and a figure from even six months ago may be materially off. Forbes and Bloomberg both use holdings-based calculations tied to real-time or near-real-time market prices. For a figure to be credible, it needs to specify the share price used, the share count it is based on, and whether foundation assets are excluded from the personal total.

Aggregator sites like CineNetWorth publish single-number estimates without disclosed methodology. Treat those figures as starting points for curiosity, not as reliable data. If you cannot trace a net worth claim back to a proxy filing, a 990-PF, or a documented share count, it is speculation.

What changes the reported number over time

Several forces can push Susie Buffett's estimated net worth up or down significantly from one year to the next, independent of anything she does personally.

• Berkshire Hathaway share price swings: Because her wealth is concentrated in Berkshire, a 15 to 20 percent move in BRK shares (which is not unusual over a 12-month period) translates directly into a proportional change in any holdings-based estimate.
• Annual charitable share donations from Warren Buffett: Each year Warren donates additional Berkshire shares to Sherwood Foundation, which increases the foundation's asset base and may increase her personal holdings if any shares are gifted to her directly rather than to the foundation.
• Estate planning and trust structures: Warren Buffett has been transparent about the fact that his children will not inherit his fortune directly; the bulk goes to philanthropy. However, prior gifts and foundation endowments are already legally separated from his estate, so the estate-planning picture affects future flows more than current foundation balances.
• Board compensation structure changes at Berkshire: If Berkshire adjusts how it compensates directors, that flows through to Susie's personal income.
• Shift in giving structure: In recent years, Buffett has periodically restructured or announced changes to his philanthropic commitments. Wikipedia notes transitions in how and to whom he directs major gifts, and any such shift can materially change how much flows to Sherwood versus other foundations.
• IRS scrutiny and payout requirements: Private foundations are required to distribute at least 5 percent of their assets annually for charitable purposes. Changes in Sherwood's asset base (driven by Berkshire share price) affect required payouts, which in turn affect how the foundation's balance sheet evolves.

A clear takeaway and what to look for right now

Susie Buffett is genuinely wealthy, sits on the board of one of the world's most valuable companies, and oversees a major private foundation. But her personal net worth is not the same as the Sherwood Foundation's assets, and it is not the same as her father's net worth. The figure most defensible from public documentation is somewhere in the $100 million to $500 million range as of mid-2026, driven primarily by direct Berkshire share holdings and personal compensation, with the Sherwood Foundation's several-hundred-million-dollar asset base sitting separately as a charitable entity.

If you are trying to document or verify this figure for research, journalism, or general reference, here is your practical checklist:

1. Pull the most recent Berkshire Hathaway DEF 14A proxy from SEC EDGAR and find Susan Alice Buffett's beneficial ownership and director compensation disclosures.
2. Search ProPublica Nonprofit Explorer for the Sherwood Foundation and open the most recent Form 990-PF to find officer compensation (Susie's personal income from the foundation) and total foundation assets (which are NOT her personal net worth).
3. Check SEC EDGAR for Warren Buffett's most recent Schedule 13D/A to identify how many Berkshire Class B shares were most recently donated to Sherwood Foundation and the transaction date.
4. Apply the current Berkshire Class B share price to any documented personal share holdings to estimate her direct holdings value.
5. Explicitly exclude the Sherwood Foundation's total assets from your personal net worth calculation unless you can document that those assets revert to her personally (they do not).
6. Note the as-of date for any estimate you publish or cite, and flag that Berkshire share price volatility makes the figure a moving target.
7. Treat any aggregator site estimate that lacks a methodology footnote or primary source reference as unverified.

For readers interested in how wealth documentation works more broadly across philanthropic families and public figures, the same verification framework applies to other notable figures in this space. The combination of SEC filings, IRS 990-PF documents, and proxy statements is the most reliable toolkit available for anyone trying to build a rigorous, source-backed picture of wealth in the Buffett family or similar situations where charity, trust structures, and private holdings intersect.
