The Evidence-Based Retirement: The 7 Risks That Actually Decide It

Two people can retire with the exact same balance and end up in completely different places — one comfortable for life, one anxious and short at eighty-five. The difference isn’t the size of the pile. It’s whether the plan accounts for the seven risks that quietly decide how a retirement actually goes.

We call our approach evidence-based for a simple reason: we don’t start from an opinion or a product. We read your situation against these seven risks, on your real numbers, and we follow what the research says — not what sells. Here’s the whole framework in one place.

1. Sequence-of-returns risk

While you’re saving, the average return over the years is what matters. In retirement, the order of returns matters far more. A bad market in your first years — while you’re withdrawing — can permanently damage a plan even if the long-run average is fine. Two retirees with identical average returns can end up worlds apart because one got a bad first act. It’s one of the most under-appreciated risks in all of retirement research (see the work of Wade Pfau).

2. Longevity

If you knew exactly how long you’d live, this would be a napkin math problem. You don’t. For a healthy 65-year-old couple, there’s roughly a 50% chance at least one of you lives past 90 (SSA data). The danger isn’t dying too soon — it’s living a long time and watching the plan run thin when there’s nothing left to do about it.

3. Inflation

Fixed income feels safe at 65 and can feel very different at 85. Even modest inflation quietly halves your purchasing power over a couple of decades. A real plan has income built to grow, not just income that exists today.

4. Taxes (RMDs and Medicare surcharges)

Most retirement money sits in pre-tax accounts you have a silent partner in — the IRS decides its share later. At your required-withdrawal age, money is forced out whether you need it or not, stacking on Social Security and often lifting Medicare premiums (IRMAA). Many people land in a higher bracket in their seventies than they were in while working.

5. Long-term care

A multi-year care event is the single fastest way to undo a lifetime of saving. For most plans, the honest answer to “where would that money come from?” is “straight from savings.” It’s either hedged in advance or it isn’t.

6. Legacy — the inherited-IRA tax

Under the SECURE Act, most non-spouse heirs must empty an inherited pre-tax IRA within ten years — usually during their own peak-earning years, at their own higher rates. Naming a beneficiary is not the same as planning the tax. Heirs can inherit a tax bill instead of a legacy.

7. Survivor — the “widow’s penalty”

When one spouse passes, one of two Social Security checks stops — but the income doesn’t fall nearly as much as the tax brackets do. The survivor files single, on brackets cut roughly in half, often on similar income. For many couples it’s the most expensive thing in the whole plan, and it’s either planned for in advance or it can’t be fixed.

What the evidence says to do about them

Here’s the part that surprises people: the research doesn’t hand you a product or a magic percentage. It points to a structure. Cover your essential expenses with income that’s reliable and doesn’t depend on the market — a floor — and invest the rest for growth. Studies on the retirement-income “efficient frontier” (Pfau) find that a blend of guaranteed income and investments can beat either approach alone. How big that floor should be, or whether you even need one, depends entirely on your numbers. That’s why it can’t be a rule of thumb, and it can’t be a single product. It has to be a reading, then a plan fitted to you.

How to read your own retirement

We built a simple way to see where you stand across all seven: the Retirement MRI, a plain-English self-check that scores each risk as hedged, partly hedged, or exposed. From there, we show you two plans — your current one and an optimal one — side by side, on the only number you actually spend: after-tax income. Sometimes the honest answer is “you’re in great shape, keep what you have.” When that’s true, we say so.

If you take one idea from this page, let it be this: your retirement isn’t decided by how much you saved. It’s decided by how well these seven risks are managed. Get them read — before, not after.
