Your Early Retirement Checklist in Four Go/No-Go Gates

In 2026, Physician on FIRE published a fresh edition of The Nightmare Before Retirement, his guide to the mistakes that unravel doctors on their way out the door. He retired from anesthesiology in his early forties in 2019 with a plan he had documented in public for years, and even he framed the exit as a horror story. That should recalibrate where your fear goes. A high savings rate fixes almost any mistake during accumulation. In the exit window, roughly the last two years before your FIRE date, the same mistakes stop being cheap, and the typical early retirement checklist will not warn you, because it was written for a 65-year-old filling out Medicare forms.

So set aside, for a moment, the question of whether you have enough. Replace it with a better one: in what order do the final 24 months need to happen, and what does each known exit hazard cost if you get it wrong? That is what this audit answers. Four gates, at months 24, 12, 6, and 0 before your quit date. Each gate has a pass/fail test, and each failure has a computable price in months of your life. By the end you will hold a written go/no-go rule that names exactly which failures delay the date and by how long, so any delay becomes a decision instead of drift.

Where FIRE plans break, and why standard checklists miss it

Run down a mainline pre-retirement checklist and notice its age bias: Medicare eligibility at 65, Social Security claiming between 62 and 70, required minimum distributions starting in your seventies. Useful, eventually. If you are retiring early at 45, a checklist built around those milestones misses the three constraints that actually bind you: penalty-free access to money you already own, health insurance that does not hit an income cliff, and sequence of returns risk across a 40-to-60-year retirement.

FIRE content does cover these hazards, individually and often well. Physician on FIRE's own site has long-running material on marketplace premiums, conversion ladders, and bond tents. What the ecosystem lacks is sequencing, and sequencing matters because the hazards are coupled in time. The Roth conversion ladder you start at month 12 changes the MAGI you test at month 6. Leaving your job in December instead of January can flip both your rule-of-55 eligibility and your first-year subsidy in the same month. A gate calendar is the missing layer: a pre-retirement checklist for FIRE ordered by deadline instead of by topic.

The pricing rule that turns every failure into FI months

Every exit hazard, from a blown bridge to a crossed subsidy cliff, converts into one currency. Before the FIRE date, a failure costs extra work-months. After it, the same failure costs lost runway.

Extra work-months = damage ÷ monthly savings (failures caught before the date)

Lost FI-months = damage ÷ monthly spending (failures that land after it)

The two denominators are far apart for someone in the final stretch of FIRE. Take a household spending $5,000 a month and saving $7,500, a 60 percent savings rate. A $10,000 mistake caught before the date costs $10,000 ÷ $7,500, about 1.3 extra work-months. The same $10,000 after the date costs $10,000 ÷ $5,000, or 2.0 lost FI-months. The ratio equals your savings rate divided by one minus it: roughly 1.5x at a 60 percent savings rate, about 2.3x at 70 percent. Damage discovered after you quit is structurally more expensive, and it tends to arrive during drawdowns, when you are selling assets to pay for it.

That asymmetry is the entire rationale for front-loading the audit. Every gate below exists to catch a failure while it still prices at the cheap rate. Run both formulas on your own income and spending now, because every price tag in the next four sections assumes you can.

Gate 1 at month 24, stress test the plan and set the glidepath

The test. Rerun your financial independence withdrawal plan at the portfolio value you project for month 0, and force the opening decade to match the worst historical starts, sequences like 1929, 1973, 2000, and 2008. Sequence of returns risk is the trap where your average return looks acceptable over 40 years while a bad first decade permanently impairs the plan, because withdrawals compound the drawdown. Bengen's 1994 study gave us the classic 4 percent rule, but that covered 30-year retirements. For 40-to-50-year horizons, long backtests such as Early Retirement Now's series commonly land closer to 3.25 to 3.5 percent as a sustainable starting rate. Your test: the plan survives a historically bad early sequence, and the projected portfolio supports your spending at 3.25 to 3.5 percent.

The pass condition. Both checks hold with no assumed spending cuts.

The price of failure. Say spending is $60,000 a year and your sustainable rate is 3.4 percent, so the target is about $1.77 million. At month 24 you project $1.68 million, an $85,000 shortfall. At $7,500 a month of savings that is about 11 extra work-months, call it a 12-month delay. Catching it here means the delay gets scheduled rather than discovered.

The action most people miss. Month 24 is also when you set the bond tent allocation or rising-equity glidepath, the pattern Michael Kitces' research popularized, shifting the portfolio defensive for the exit window. Do it now, inside tax-advantaged accounts, because rebalancing into bonds at month 3 from a taxable account that just dropped 20 percent converts a timing problem into a realized loss.

Gate 2 at month 12, audit the bridge to penalty-free money

The test. Build a year-by-year access map from your FIRE date to age 59 and a half in which every dollar of spending has a named account and, where needed, a named exception. The default is ugly: withdrawals from tax-deferred accounts before 59 and a half generally owe a 10 percent penalty on top of ordinary income unless an exception applies, and the exceptions are narrower than forum threads suggest. The IRS rule of 55 works only from the plan of the employer you separate from, and only if you leave in or after the year you turn 55. Substantially equal periodic payments under Revenue Ruling 2002-62 lock you into rigid distributions for five years or until 59 and a half, whichever is later, with retroactive penalties if you break the schedule. Seasoned Roth contributions can come out anytime, but each conversion has its own five-tax-year clock before the converted dollars are penalty-free.

The pass condition. The bridge shows zero penalty dollars in every year, funded by some mix of taxable accounts, Roth basis, a conversion ladder, and rule-of-55 or 72(t) distributions where they genuinely fit. The rule of 55 vs 72(t) debate resolves into arithmetic here: pick the exception your employer plan and timeline actually support, confirmed in writing by the plan administrator.

Roth conversion ladder timing

The ladder is the long-lead item, and the question of when to start a Roth conversion ladder before FIRE answers itself once you see the seasoning clock. Each rung becomes usable five tax years after the conversion, so a ladder started in your first FIRE year covers roughly year six onward. That leaves years one through five to taxable money, seasoned Roth basis, or a genuine exception, and no amount of ladder enthusiasm fixes it retroactively in month 11.

The price of failure. Suppose the map shows a $40,000 hole in year three that only a 401(k) withdrawal can fill at age 45. The 10 percent penalty on withdrawals before 59 and a half costs $4,000, certain and computable: $4,000 ÷ $5,000 of monthly spending is 0.8 lost FI-months. Annoying, not fatal. The expensive part of a red Gate 2 is the fix's lead time.

Gate 3 at month 6, run MAGI against the ACA subsidy cliff

For 2026, the enhanced premium tax credits that suspended the income cap have expired, so the premium tax credit cliff is back: eligibility ends at a hard income line, roughly 400 percent of the federal poverty line under the pre-2021 rules, and one dollar of MAGI over it can wipe out the entire credit, a loss worth thousands of dollars a year for a household. KFF's premium payment analysis maps how unevenly the resulting increases landed, and the exact line for your household size comes from the HHS poverty guidelines. Verify both before you lock a date.

The test. Project MAGI for your first three FIRE years, line by line. This is where the 2026 MAGI rules for early retirement trip people up. Long-term capital gains harvested at a 0 percent tax rate still count fully toward MAGI. A nonqualified deferred comp payout that lands the year you leave can drop a lump into year one. Every Roth conversion rung is taxable income competing directly with your subsidy. The MAGI picture is something you build, not something you inherit.

The pass condition. Every projected year sits safely under the line with a stated buffer, and you know which levers move MAGI down: cash spending, deferred conversions, timed gains.

COBRA or Marketplace in month one

Coverage timing is part of the gate. Losing employer coverage opens a 60-day marketplace special enrollment window, and electing COBRA first generally locks you out of a subsidized marketplace plan until the next open enrollment. COBRA keeps your doctors, typically for up to 18 months, at full price. The marketplace plan is the one your MAGI math actually applies to.

The price of failure. Illustrative numbers: a couple just under the line with an $18,000 benchmark premium paying $6,000 net crosses it by a single dollar and owes the full $18,000. The $12,000 credit loss ÷ $5,000 of monthly spending is 2.4 lost FI-months, and the cliff is retested every single year.

Gate 4 at month 0, the go/no-go decision rule

The go/no-go decision to retire early is a document, not a feeling, and the document gets written weeks before the date, while you are still calm.

The written rule

• All four gates green: go, on the date.
• Gate 3 amber, meaning your MAGI projection lands within a few thousand of the line: delay six months, restructure income, retest.
• Gate 1 red, meaning the stress test fails: delay twelve months and recompute.
• One amber anywhere else: delay six months maximum, with no rolling re-ups without re-running the entire audit.

Month 0 is precisely when you are least able to improvise, which is the whole reason the rule exists before you need it.

The cash buffer

How much cash buffer before retiring early? This audit's answer is 12 to 24 months of spending, funded by month 0. Its job is specific: if the market drops 25 percent in your first year, the buffer converts forced selling from a permanent sequence-of-returns loss into a temporary timing problem. You spend cash and let the portfolio recover.

The logistics sweep

Beneficiary designations on every account and policy, because a will does not override them. Your final employer match, since some plans match per paycheck and a mid-year exit forfeits the rest. ESPP shares, where selling immediately triggers ordinary income on the discount while holding adds company stock risk in your first year without a paycheck. Deferred comp payout elections, often fixed in advance and taxable the year they pay. HSA receipts, which you can hold and reimburse anytime. None of these are large. All of them have deadlines.

Pricing the one more year option without the syndrome

One more year syndrome is drift: work as anxiety relief, with no exit condition. Treat the extra year as a priced option instead. At the illustrative numbers, one additional working year adds $90,000 of annual savings, about $80,000 of portfolio growth on $1.6 million at 5 percent, and $60,000 the portfolio keeps because you skip a year of withdrawals. Call it $230,000 of total runway, more than the price of several typical gate failures combined. That is exactly why the leave-now math has to be written before month 0: the marginal year will always look financially positive, so it can never be the deciding argument.

Leave anyway when all four gates are green, the buffer is funded, and the failure the extra year would insure against is one your stress test already survived. Past that point you are paying twelve months of your remaining life to buy insurance you have already bought, and no savings rate fixes that trade.

The full early retirement checklist on one page

This week, on your own numbers: compute your monthly savings and monthly spending, write the two conversion formulas at the top of a page, and fill in the price column with your own damage estimates. Then write the delay rule and sign it. A FIRE readiness audit ends with a date you can defend and a plan for the day something turns red. Even the doctor who wrote the cautionary tale kept his exit date. The difference between a nightmare and an audit is that the audit has a calendar.
