The default retirement design in American financial planning is a cliff: you work at full intensity until a chosen date, and the next Monday you never work again. That design was built for careers that physicians do not have. It ignores what eleven to fifteen years of training does to professional identity, it ignores the strange economics of maintaining a medical license you are not using, and it ignores the most physician-specific fact of all — that clinical skill decays on a one-way ratchet, so the decision to stop is nearly irreversible while the decision to slow down is not. There is a better design available, and physicians are unusually well positioned to use it: the glide path. Reduce clinical effort in planned steps — 1.0 FTE to 0.6 to 0.3 to zero — over five to ten years, and let part-time income do quiet, enormous work in the portfolio math along the way.
The cliff retirement fits physicians worse than almost anyone
Three asymmetries make the cliff a poor fit for medicine.
The first is identity. A physician who retires at sixty has typically spent more than half their life inside the profession — training, call, the accumulated weight of patients known by name. Survey after survey of retired physicians reports the same finding: the loss of professional identity, not money, is the dominant adjustment problem. A glide path lets identity taper at the same rate as the schedule.
The second is the licensure maintenance ledger. Keeping a license active costs real money and time — state registration, federal prescribing registration, board maintenance fees, and continuing education requirements typically total a few thousand dollars per year plus dozens of hours. Against a full-time attending income that overhead is a rounding error. Against zero income it is pure cost, which is why fully retired physicians almost always let credentials lapse within a year or two. But at 0.3 FTE, even one clinic day per week comfortably carries the entire maintenance ledger and keeps every option open.
The third asymmetry is the decisive one. Stepping down is reversible; stepping out is not. A physician who leaves practice for more than roughly two years faces re-entry as a formal problem — credentialing gaps to explain, hospitals that require proctoring or supervised practice, and in procedural specialties the honest question of whether the hands still have it. The glide path never triggers any of it, because you never leave. Working 0.3 FTE at sixty-two, you retain the ability to move back to 0.6 if the portfolio disappoints, the marriage needs the house to itself less, or the work turns out to be the part you liked. The retired physician at sixty-two holds no such option, at any price.
The glide path arithmetic: 1.0 to 0.6 to 0.3
Here is the shape of the thing in numbers, using a $420,000 full-time income as the illustration — adjust to your specialty.
| Stage | Approximate income | Typical benefits status | Typical schedule reality |
|---|---|---|---|
| 1.0 FTE | $420,000 | Full benefits, full retirement | Full call share |
| 0.6 FTE | ~$240,000–$252,000 | Usually retains employer coverage and match eligibility | Call often NOT prorated unless negotiated |
| 0.3 FTE | ~$115,000–$126,000 | Frequently BELOW the benefits eligibility threshold | Call usually excluded; schedule is the point |
| 0.0 FTE | $0 | None | — |
Two honest footnotes to the table. Income rarely scales perfectly with FTE — production-based contracts with fixed components, thresholds set for full-time volumes, and stipends that vanish below full time all tend to make 0.6 FTE pay slightly less than 60 percent. Model conservatively.
The second footnote is the one that catches physicians by surprise: the benefits cliff. Most employed positions condition health coverage and retirement plan eligibility on a minimum FTE, commonly somewhere between 0.5 and 0.75. The step from 0.6 to 0.3 is therefore not a smooth income reduction — it is the step where employer health coverage typically ends.
Important
Price the benefits cliff before you step off it. As of 2026, the enhanced marketplace premium subsidies expired on December 31, 2025, and the 400-percent-of-poverty subsidy cliff is back — a household with $126,000 of part-time clinical income buys individual coverage at full, unsubsidized price. For a physician couple in their late fifties, that can mean paying $25,000 to $35,000 per year for coverage that cost a payroll deduction at 0.6 FTE. The 0.6-to-0.3 step deserves more planning than the 1.0-to-0.6 step, even though it looks smaller.
Each $50,000 of clinical income deletes $1.25 million of required portfolio
Now the part that changes retirement dates. The standard sizing heuristic multiplies annual portfolio-funded spending by 25, corresponding to a 4 percent initial withdrawal rate — the full logic lives in the freedom number module. Part-time income attacks that multiplication directly, because every dollar of spending covered by clinical work is a dollar the portfolio never has to produce.
Example calculation
Assumptions, stated explicitly: household spending of $200,000 per year; the ×25 heuristic (4% initial withdrawal rate); part-time income figures treated as spending-equivalent for illustration — in practice, apply your after-tax rate; the subtraction holds only for the years you actually work.
Full cliff retirement: $200,000 × 25 = $5,000,000 required Working 0.3 FTE at $126,000: ($200,000 − $126,000) × 25 = $1,850,000 required while working Per increment: each $50,000 of clinical income × 25 = $1,250,000 less portfolio needed
A physician with $2.5M at fifty-eight cannot support $200,000 of spending on the ×25 heuristic — but can fully support it at 0.3 FTE, while the portfolio compounds untouched toward the eventual full-stop number.
Read the calculation honestly: part-time income is temporary, so the $1.85 million figure is not your permanent number — it is the number that makes the glide years self-funding. The real effect is sequencing. Five years at 0.3 FTE with zero withdrawals lets a $2.5 million portfolio grow toward $3.3–3.5 million at moderate returns, while you add five years of maximum retirement contributions on the way through. The glide path does not lower the destination; it moves you toward it while already living most of the retirement schedule.
Part-time income is the strongest sequence-risk shield you can buy
The greatest threat to any retirement portfolio is not average returns — it is bad returns in the first decade, when withdrawals during a drawdown sell assets at depressed prices and permanently shrink the base. Two retirees with identical average returns over thirty years can end with wildly different outcomes purely on the order in which those returns arrive.
Part-time clinical income is a direct answer to sequence risk, and it is an answer most retirees cannot access. A physician covering $126,000 of a $200,000 budget at 0.3 FTE withdraws roughly 1.5 percent of a $5 million portfolio instead of 4 percent — and in a genuine bear market can move to zero withdrawals, or step back up to 0.6 FTE, options that convert the worst-case decade into a survivable one.
Key insight
Insurance framing makes the value concrete: eliminating sequence-of-returns risk through products or cash buffers costs real expected return. One clinic day per week accomplishes the same protection while paying you — the option to increase clinical effort is a put option on your own portfolio, and physicians hold it for free as long as the license and credentials stay warm.
Call, tail, and credentials do not scale down neatly
The glide path works, but three practicalities decide whether it works pleasantly.
Call is the first. Call burdens are frequently allocated per head, not per FTE — the 0.6 FTE internist asked to carry a full call share is working a 0.75 job for 0.6 pay. Weekend and night call are also, for most physicians past fifty-five, precisely the part the glide path exists to shed. Call expectations at each FTE step must be written, not assumed.
Malpractice is the second. If your reduction involves changing employers or moving from employed to independent or locums work, a claims-made policy triggers the tail question — tail coverage typically costs 1.5 to 2 times the expiring annual premium as a lump sum, per industry guides current in 2026. A within-employer FTE reduction usually avoids this entirely, which is a real argument for gliding down where you already work. Some carriers also offer free tail at full retirement after a minimum insured period — worth confirming before you structure the final step.
Credentialing is the third. Hospital privileges in procedural specialties often carry minimum case-volume requirements, and board maintenance continues at full cost regardless of FTE. At 0.3 FTE a proceduralist may need to concentrate effort — one full operative day per week beats two scattered half-days — specifically to keep volumes above renewal thresholds.
Part-time is a contract change — negotiate it like one
An FTE reduction is an amendment to your employment agreement, and it deserves the same scrutiny as the original contract — the contract red flags module applies in full. The terms that matter most at reduced FTE:
- The FTE definition itself — clinical hours, or clinical plus administrative? A 0.6 FTE defined on clinical hours with undiminished committee load is not 0.6.
- Production thresholds prorated in writing — wRVU targets and bonus floors built for full-time volumes must scale, or your compensation quietly falls below the FTE ratio.
- Call, in numbers — a stated ratio at each step, not "as assigned."
- The benefits eligibility threshold, in writing — know the exact FTE at which coverage and match end before choosing your steps around it.
- Tail responsibility on any future separation, negotiated now while you have leverage as a retained senior physician.
- A return path — language permitting an increase back to a higher FTE by mutual agreement costs the employer little and preserves your sequence-risk option.
Employers say yes to this more often than physicians expect. Replacing a senior physician costs a recruitment cycle, a signing package, and one to two years of ramp-up; keeping sixty percent of one is usually the better deal, and both sides know it.
Quick takeaway
The glide path is not semi-retirement as consolation prize — it is the superior design: identity tapers instead of snapping, the license pays its own maintenance, each $50,000 of income stands in for $1.25 million of portfolio, and the option to step back up is free sequence-risk insurance no product can match. The physicians who regret it are mostly the ones who negotiated it badly.

Common questions
At what portfolio size does the first step down make sense?
A workable screen: when the ×25 arithmetic works at your reduced income — spending minus expected part-time income, times 25, comfortably below the current portfolio — the step is self-funding and the portfolio keeps compounding. Many physicians find 0.8 or 0.6 FTE defensible years before the full-stop number is in sight, precisely because the step defers withdrawals rather than starting them.
Does part-time work delay when I can take retirement account withdrawals?
No — eligibility for penalty-free access is driven by age and account rules, not employment status. Part-time work usually improves the picture: income fills the years before 59½, reducing or eliminating the need for early-access strategies, and continued employment may preserve access to the employer plan and its loan or separation provisions.
What about board certification if my volumes drop?
Maintenance of certification is largely FTE-independent — fees, assessments, and improvement activities continue regardless. The FTE-sensitive item is hospital privileging with case-volume minimums. Check your renewal thresholds before designing the schedule, and concentrate clinical time rather than scattering it if volumes are close.
Is 0.3 FTE income really worth it after taxes and overhead?
Run your own ledger: at $126,000, after payroll taxes and a few thousand in maintenance costs, a six-figure net remains — while every year of it spares the portfolio roughly $75,000 to $125,000 of withdrawals plus the growth those dollars would have missed. The years where it stops being worth it announce themselves clearly; that is what the final step to zero is for.
What to do next
- Read your current contract's FTE, benefits eligibility, and call provisions — the thresholds that shape your steps are already written down, and reading them costs nothing.
- Compute your glide arithmetic: spending, minus realistic after-tax income at 0.6 and 0.3 FTE, times 25, against your current portfolio.
- Price post-employer health coverage for your household on the marketplace at full cost — before assuming the 0.3 step works.
- Confirm your malpractice structure: claims-made or occurrence, who owns the tail, and whether free retirement tail exists after a minimum period.
- Sketch the steps with dates — even a provisional 1.0/0.6/0.3 schedule converts retirement from a cliff you dread into a design you control.
- Open the FTE conversation with your employer eighteen to twenty-four months before step one; the negotiation is easiest while replacing you is their problem, not yours.
The glide path asks one design question — why should the last decade of a medical career look like a light switch — and every piece of the math above answers it the same way; the framework works with or without us. This is education, not individualized financial advice.
