The Bucket Strategy: Three-Account Retirement Income Planning

The classic three-bucket strategy holds cash (bucket 1) for 1-2 years of expenses, high-quality bonds (bucket 2) for years 3-7, and diversified equities (bucket 3) for the long term. Retiree spends from bucket 1, refills it from bucket 2 during normal market conditions, and from bucket 3 during strong years. During bear markets, the retiree lives entirely off bucket 1 without touching equities, avoiding selling at depressed prices. Once equities recover, bucket 3 refills the bond bucket, which in turn refills the cash bucket. The psychological benefit is significant: knowing you have 5-7 years of guaranteed income covered lets you sleep through a market crash. The mathematical benefit is debated.

Harold Evensky, a veteran financial planner, is typically credited with popularizing the bucket strategy in the 1980s. Christine Benz of Morningstar has been a prominent modern advocate. The strategy became widely adopted in the 2000s after retirees who held cash reserves through the 2000-2002 dot-com crash and 2008-2009 financial crisis fared psychologically much better than those on pure total-return strategies — even when outcomes were mathematically similar.

Here's the contested part: multiple academic studies have shown that the bucket strategy often does not mathematically outperform a simpler total-return approach with the same overall asset allocation. If bucket 1 holds $40K cash and bucket 3 holds $800K stocks, that's the same asset allocation as a total-return portfolio at 95/5 stocks/cash — and the total-return approach avoids the friction of manually refilling buckets. The bucket approach's benefits are primarily behavioral: retirees perceive it as safer and stick with their equity exposure through downturns, which matters. Second: the 'refill' decisions are effectively market-timing decisions, and retirees make them poorly. Rules like 'refill bucket 1 from bucket 2 monthly' are more robust than 'refill when it feels right'. Third: bucket 1 (cash) often underperforms inflation, acting as a drag on long-term returns — this is the cost of the psychological comfort. Fourth: implementing buckets across multiple tax-treatment accounts (Roth, traditional, taxable) can be operationally complex.
