There is no verified global ranking of the richest interior designers. The clearest comparable figures available here are third-party net-worth estimates: Celebrity Net Worth lists Kelly Wearstler at $150 million and Nate Berkus at $18 million, both updated May 22, 2026. Neither figure is an audited disclosure, and the evidence is not enough to rank designers worldwide or across history.
Published net-worth estimates: Kelly Wearstler and Nate Berkus
These are estimates of individual wealth, not confirmed balances. Celebrity Net Worth does not provide an audited personal financial statement or a transparent methodology in the material cited, so the amounts should be read as claims by that publisher rather than verified fortunes.
| Designer | Published estimate | Publisher and update date | Business scope described by the source | Evidence limits |
|---|---|---|---|---|
| Kelly Wearstler | $150 million | Celebrity Net Worth, updated May 22, 2026 | Interior design and hospitality work | Third-party estimate; not an audited disclosure. The source does not establish a transparent valuation method. |
| Nate Berkus | $18 million | Celebrity Net Worth, updated May 22, 2026 | Design, television, production, and author work | Third-party estimate; not an audited disclosure. The source does not establish a transparent valuation method. |
On this one publisher’s estimates, Wearstler’s listed figure is higher. That comparison does not prove either person’s actual wealth, nor does it show that the publisher values their assets and liabilities using a consistent accounting method.
Why this is not a definitive “world ever” ranking
The available figures do not establish a complete list of wealthy designers, cover every country or period, or provide a consistent basis for ordering individuals. A published net-worth estimate can be useful as a rough indication of public perception, but it is not equivalent to a financial disclosure.

#1 Best Overall
- Estimates are not audited wealth: the cited pages do not offer verified personal balance sheets or a transparent valuation methodology.
- The sources may count different things: design businesses, media work, product ventures, and other assets may be treated differently, while liabilities are not made clear.
- Order depends on the source and method: the two figures above come from the same outlet, but that alone does not establish consistent accounting or global coverage.
Personal net worth is not the same as a design firm’s earnings
Interior Design magazine’s 2026 Top 100 Giants report says the firms in its ranking generated a combined $6.38 billion in design-fee income for 2025. The ranking is based on total design-fee earnings across the vertical; it measures firm income, not the personal net worth of any designer or owner. See the 2026 Top 100 Giants report.
Firm revenue is not personal wealth. A company’s fee income does not reveal its expenses, ownership shares, debts, or how much money an individual ultimately holds. It should not be added to a designer’s estimated net worth or used to rank individuals.

Designers may earn money from more than client projects. A career can extend into products, hospitality, publishing, television, production, or licensing. Those activities help explain why a public estimate might consider multiple income streams, but they do not establish the person’s assets, debts, ownership stakes, or actual net worth.
Kelly Wearstler: design and a broader lifestyle brand
Wearstler’s official catalog describes a global lifestyle brand spanning residential and commercial interiors as well as product collections. The catalog includes furniture, lighting, rugs, fabrics and trims, wall coverings, bedding, fine china, accessories, jewelry, and objets d’art. View the official catalog. It supports the description of a diversified brand, not the $150 million estimate; the catalog is dated and does not establish which items are currently available.

Celebrity Net Worth describes Berkus’s work across design, television, production, and authorship. His page identifies the books The Things That Matter and Home Rules; those titles illustrate publishing as one part of a public-facing career, but do not verify the estimate or disclose book income.
Quick Recap

What to check before trusting a designer net-worth number
- Identify what is being valued: an individual, a couple, a family, a company, or a collection of brands are not interchangeable subjects.
- Read the date and attribution: estimates can change and should be quoted with the publisher and its update date.
- Separate income from wealth: annual fees or sales are flows of business revenue, not a person’s net worth.
- Look for disclosed method and evidence: without audited statements, documented assets, and liabilities, treat a number as an estimate rather than a fact.
