The shift from building wealth to living on it is the most consequential financial transition most people make, and the one with the fewest second chances. Which account funds which year, when to claim Social Security, and what changes the year the paychecks stop.
For thirty years your financial life had a shock absorber: earned income. It covered surprises, it made a bad market year survivable, and it meant your portfolio was never the only thing standing between you and a problem. That absorber disappears, and everything about how the portfolio should be built changes with it. We wrote about what that shift actually asks of a plan.
The conventional advice is taxable first, then tax-deferred, then Roth. It's simple, and for large portfolios it frequently costs more than it saves, because it wastes the low income years between retiring and required distributions when your marginal rate is at its lowest for the rest of your life. Which account you draw from first affects both your own tax bill and what your heirs eventually receive.
Those same low income years are usually when a Roth conversion makes the most sense, if it makes sense at all. The comparison that settles it is simpler than most conversion calculators suggest.
Most claiming analysis asks at what age the cumulative dollars cross over. For a household that doesn't need the income, that's the wrong question. What matters more is the survivor benefit, and the tax room that delaying creates for other decisions. There are also cases where claiming early is right, and they're not the ones people expect.
The original research studied a specific portfolio, a specific time period, and a household with no meaningful tax complexity and no flexibility to adjust. Almost none of that describes a large portfolio. What the rule leaves out matters more than the number itself.
If you're approaching this transition, or already in it, we're happy to talk it through. It costs nothing to have the conversation.
