The 4% withdrawal drain is eating the inheritance

Two corners of the retirement industry are now warning that the decumulation phase has a leak, and it sits squarely in an advisor's lap: RIABiz reports that a Boston firm calls client withdrawals of around 4% a giant drain on portfolios, while a Moss Adams consultant argues hungry Boomers are spending the money their children expect to inherit. Put the two claims side by side, and the Great Wealth Transfer starts to look less like a wave and more like a slow leak.

At 4% a year, a $100 million book loses $4 million annually, which over a decade is $40 million of spending before market returns enter the picture. That is a planning problem because the spending number is the one variable an advisor can influence. Review the actual withdrawal rate, test it against probability-based guardrails, and tighten it after down years so a bad sequence does not end the plan; the sequence risk is real, but the spending rule is where the advisor has leverage, and a guardrail that lets the client spend less after a down year can add years to the portfolio.

The last mile of retirement has become the advisory battleground because clients who built wealth through accumulation habits often lack a spending plan, and a 4% drain goes unnoticed until it becomes a balance problem. Advisors who catch it early are doing more than preserving assets; they are preserving the relationship through the phase when clients most need help and most often switch firms.

The familiar retirement levers — Social Security claiming, Roth conversion sequencing, and bucket design — remain the advisor's tools, but the new emphasis is behavioral: making the drain visible to the client before the statement does it. As this publication has argued, the plan becomes the product: the advisor who models the decumulation path owns the relationship, and the drain becomes the referral fee.

The Moss Adams claim extends that argument across generations. If Boomers are spending their children's inheritance, the estate-transfer conversation is premature; the first conversation should be about lifetime income. Whether the Great Wealth Transfer is a mirage will be answered by client behavior. The advisors who matter will already be inside every client plan finding the 4% drain — modeling it, fitting guardrails to it, and making it visible before the children start asking where the money went.
