Who Is Bob Clyatt

Bob Clyatt combines experience and insight in his leading book on early retirement advice. Bob’s extensive education in finance and economics, including degrees from Berkeley and MIT where he studied under leading Nobel-prize winning economists, combine with his artist’s idealism to forge a unique blend of pragmatism and vision for the long-term retiree.

After 20 years in the business world, including founding two start-ups sold to public companies, Bob left full-time career work at age 42 to re-connect to his family, “his sanity”, and pursue a cherished dream to write and create art.

To convince himself that he was not irresponsibly risking his family’s well-being, he immersed himself in the early retirement literature and finance, interviewing hundreds of others on the path, and contributing innovative research to safe withdrawal rates (from retirement accounts) studies and long-term investing strategies tailored to the needs of early retirees.

He clarified and advocated the 4%-of-principal withdrawal (as opposed to an initial 4% rising by inflation in subsequent years) coupled with his 95% Rule which are becoming mainstream thinking for long term retiree finance.
