The Retire REGAL® framework rests on a single premise: that the decisions of retirement — income, taxes, Social Security, investments, and legacy — should be coordinated as one system, not handled in isolation. That premise is not just intuition. Independent research from Morningstar, Vanguard, and the financial-planning literature has measured what coordination is worth. Here is what they found.
The research summarized below is provided for educational purposes only. The figures cited are drawn from independent studies and are generally modeled, illustrative, or averaged results — not predictions or guarantees of any outcome for any individual. Your results depend on your own circumstances.
The Retire REGAL® framework is built from well-established planning disciplines; the value of those disciplines — and of coordinating them — has been studied extensively. The research validates the principles the framework puts into practice. Each piece below ties a body of research to one part of the framework.
This is the study that most directly mirrors the framework. Morningstar researchers David Blanchett and Paul Kaplan set out to measure the value a retiree can add not through picking better investments, but through better planning decisions. They identified five: a total-wealth approach to asset allocation, a dynamic withdrawal strategy, sensible use of guaranteed income, tax-efficient withdrawal sequencing, and liability-relative optimization. Combined and coordinated, those decisions produced an estimated 22.6% more certainty-equivalent income — and, crucially, the authors note this "Gamma" is available to anyone who follows an efficient process, unlike chasing market returns. That five-part, coordinated structure is precisely what the Five Realms are built to deliver.
How to read it honestly: 22.6% is a risk-adjusted "certainty-equivalent" measure (roughly equivalent to 1.59% of additional return per year), produced by a Monte Carlo simulation. It is a modeled result that illustrates the value of the approach — not a guaranteed return.
Vanguard's long-running research estimates that a well-run advice process can add "up to, or even exceeding, 3%" in net value per year. What matters most for the framework is where that value comes from: spending strategy (the order of withdrawals), asset location and tax efficiency, rebalancing, and behavioral coaching. Vanguard is explicit that it does not simply add these components together, "because there can be interactions between the strategies" — the same reason the framework treats the realms as one connected system rather than separate decisions.
How to read it honestly: the value is not a smooth 3% every year. It is lumpy and varies significantly by client and circumstance — concentrated in moments like a market downturn, a tax decision, or a withdrawal-sequencing choice.
A 2019 study by United Income — co-authored by a former Chief Economist of the Social Security Administration — estimated that retirees collectively forgo about $3.4 trillion in lifetime income, an average of roughly $111,000 per household, by claiming Social Security at a financially sub-optimal time. The average household could receive about 9% more lifetime income from the optimal claiming decision, yet fewer than 5% of people wait until age 70. Claiming is not an isolated choice — it interacts with taxes, withdrawals, and Roth conversions, which is exactly why the framework treats it as part of the system rather than a standalone form to fill out.
How to read it honestly: these are collective and average figures from a model. The optimal claiming age is highly individual — it depends on health, longevity expectations, marital status, and the rest of the plan.
Which accounts a retiree draws from first — taxable, tax-deferred, or Roth — measurably changes how long the money lasts. Research by Reichenstein and Meyer found that a tax-efficient withdrawal sequence — drawing from accounts in a deliberate order and using the low-tax early years — can add more than three years of portfolio longevity compared with the conventional "spend the taxable account first" rule of thumb still used by many large firms. For a household with most of its savings in tax-deferred accounts, this sequencing question is one of the highest-value decisions in the plan.
How to read it honestly: this is a modeled result, and the size of the benefit rises with wealth and rate of return. The right sequence is specific to each household's account mix and tax situation.
The years between leaving work and the start of Required Minimum Distributions are often a household's lowest-income — and lowest-tax — window. Research by Reichenstein and Meyer shows how valuable that window can be. By converting tax-deferred dollars to a Roth in those years — filling the lower brackets before RMDs and the tax-rate increase scheduled for 2026 — a retiree can avoid having those same dollars taxed later at marginal rates as high as 40 to 46 percent, a "tax torpedo" created when Social Security benefits become taxable. In one of the study's modeled cases — a household with $1.5 million in a tax-deferred account — this approach added three years of portfolio longevity and roughly $441,000 in lifetime value.
How to read it honestly: a Roth conversion may not be suitable for your situation. The benefit depends on current versus future tax rates, available cash to pay the tax, time horizon, and legacy goals — which is why it belongs inside a coordinated plan, reviewed with your tax advisor.
Honesty cuts both ways here. These studies do not prove that any one advisor, or any single branded process, will deliver a specific result. They are largely modeled, illustrative, or averaged findings, and none of them tested your plan or anyone else's by name.
What they do establish is the principle the Retire REGAL® framework is built on: that coordinating retirement decisions — income, taxes, Social Security, investments, and legacy — as one connected system tends to add real, measurable value compared with making them in isolation. The framework is simply a disciplined way to put what the research points to into practice.
Your own results will depend on your circumstances, the choices you make, and conditions no one controls. The point of the evidence is not a promise. It is a reason to take coordination seriously.
The studies describe the value in the aggregate. A Retire REGAL® Review is where it becomes specific to your plan.
