The one-more-year syndrome

One last obstacle stands between a FIRE candidate and the exit. It is not the market, and it is not the tax code. It is the candidate, who hits the target and stays. "One more year", to round the number up, to be safe, because the market is high, because the market is low, because the bonus lands in March. Then another year after that. The one-more-year syndrome (OMY) is the movement's terminal trap. It is common enough to have its own acronym on every forum, and costly enough that veterans call it their number one regret (What real FIRE retirees say: accounts and advice: "I should have left sooner", unanimously).

This chapter treats it as a planning problem, not a character flaw. The psychology comes first: why no number ever feels like enough, and why one of the two risks is visible and the other is not. Then the honest tally. What an extra year buys in safety is measurable, and it shrinks fast. What it costs is the one asset in the plan that never comes back. Rational OMY does exist, in exactly three cases, and the line between those and the syndrome is worth drawing carefully. The cure is a set of departure criteria written years ahead, while you are calm, plus a priced comparison that makes the extra year compete with every other lever. Nothing beats a moving fear except a commitment made before it showed up.

The mechanism: why no number is ever enough§

Anyone approaching the exit is boxed in on three sides.

The target moves. The moment you hit it, your mind renegotiates it ("25x, but with inflation... call it 27x, and the world is uncertain, so 30x?"). These are the moving goalposts, and they show up in every account. They have a documented root, loss aversion: a loss weighs about twice its mirror-image gain (Kahneman and Tversky, 1979, the factor measured near 2 by the same authors in 1992), so the possible ruin crushes the certain years on the mental scale. The target was never the real trigger. The real trigger is a feeling of safety, and numbers do not manufacture it (The psychology of spending: why spending it is the hard part describes the same unbounded fear, one phase earlier).

The known is comfortable. Leaving is a cliff in your identity (Meaning, identity, structure: life after work); staying is the gentle slope, and status quo bias (Samuelson and Zeckhauser, 1988) does the rest: the default option wins as long as you do not confront it. And one more year is the perfect compromise for anyone avoiding the drop. You do not give the project up. You push it back, indefinitely.

Everything around you pushes the same way. Your employer holds you with a bonus and a late promotion. The people around you doubt ("at your age?"). And the market always supplies a reason: high ("a bubble, let's wait for the correction"), low ("let's wait for the recovery"), calm ("let's bank a good year while it lasts"). Anyone who has read Valuations, the CAPE, and what they say about your withdrawal rate will recognize perpetual market timing, applied this time to a life.

The numbers: both columns, honestly§

What a year buys. That column is real, so measure it. One more year is one more year of saving (5 to 15% of capital, depending on your savings rate), one more year of expected return, one fewer year of withdrawals, one fewer year of horizon, and another year of credits toward your pension. It also slides the fragile window (Sequence of returns risk: the retiree's real enemy). ERN did the systematic calculation (Part 42, "The Effect of One More Year"). Near the target, an extra year of work improves safety by the equivalent of 0.2 to 0.4 points of withdrawal rate. For the first year that is real money: it turns a stretched plan at 4.2% into a sound one at 3.9%. After that the effect fades fast. The fifth extra year buys almost nothing, because the plan was already safe. You are squeezing a 2% failure probability toward 1.5%, decimals, in the zone where precision is an illusion anyway (Failure probability: reading it, choosing it, and not letting it run you). The safety-against-years curve flattens exactly like every other prudence curve in this book. The syndrome is standing on that flat plateau and paying full price. And the surplus safety never reaches the retiree's life. It lands in the estate, because prudent plans die rich. In kind vintages the fixed rule leaves up to nine times the starting stake (The fixed inflation-adjusted withdrawal (Bengen): the benchmark rule), a bequest nobody asked for.

What it costs. A year of your life. And not any year: one out of the best slice you have left. Here is the statistic that belongs on the wall of every open-plan office in the movement. Healthy life expectancy, the years lived without activity limits, runs to roughly 64 or 65 in rich countries, far below total life expectancy. The go-go years of someone who retires at 45, the demanding trips, the sport, the physical projects (Real spending in retirement (the retirement smile, Die With Zero)), come to a stock of about twenty years, and that stock does not stretch. It burns from both ends, by aging and by every year you postpone. The full accounting of one OMY at 45 fits on a line: plus 0.25 points of withdrawal rate on a plan already sound at 4% failure, against one twentieth of your stock of full-health years. Put that way, the trade is rarely a good one.

🔬 Rational OMY exists: the three cases

Honesty demands the opposite list, three setups where the extra year is a good buy.

The plan really is stretched (central failure above 8 to 10%, a high floor, thin margins, Choosing your strategy: criteria, comparison, worked case). The first extra year then buys its full value, on the steep part of the curve.
The market is extremely expensive on the planned exit date (Valuations, the CAPE, and what they say about your withdrawal rate). A target reached on euphoria is a fragile target, when the CAPE runs above 32 to 35 and the CAPE-anchored failure probability confirms it. Sliding 12 to 24 months, bounded, with a backstop date written down, is the defensible version of timing your own life (Accumulation, transition, withdrawal: the three lives of a FIRE plan, the trap at the top).
The life after is not ready (nothing prototyped, a spouse who is not on board, Meaning, identity, structure: life after work, FIRE as a couple, and as a family). The extra year that builds something, the four-day week, the trial sabbatical, the practices already started, is not a delay. It is preparation, as long as it has a deliverable and an end date.

One question separates the rational case from the syndrome: "What will be true in a year that is not true today, and how will I know?" The rational case has a precise answer. The syndrome answers "we'll see, I'll feel better." The research on affective forecasting says exactly the opposite: we are poor prophets of our future states, and that better feeling does not arrive on its own (Wilson and Gilbert, 2003).

The cure: a commitment made while calm§

The syndrome gets treated like every other bias in this book, with structure, decided before the emotion arrives (The psychology of spending: why spending it is the hard part). Here are the pieces, all field-tested.

Departure criteria, written years ahead. One page that freezes everything, while you are calm. The number (capital, the failure probability you accept under the models you agreed on, a floor you tested, Building your plan step by step), the life conditions (prototyping done, spouse on board), and the anti-goalposts clause. That clause says: these criteria do not get any harder. Any upward revision needs a new reason, written down, approved at the next annual review. You may always relax a criterion while calm. You may never tighten one in the heat.

The date-or-condition commitment. The most robust form of commitment there is. "I leave when the criteria are green, and at the latest on [date], criteria or no criteria, in Barista FIRE form if that is what it takes." A backstop date turns an open-ended delay into a bounded one. And the accounts show it is rarely exercised: knowing it exists is usually enough to unblock the departure on criteria.

The menu of equivalent moves. This is the instrumental anti-OMY, and it thinks like a solver. Fix the failure probability you find acceptable. Then ask, lever by lever, for the exact dose that brings the plan back under it. One more year of work. Or 5% less spending for life. Or $800 a month of side income for two years (Pensions and other income in the plan). Or simply counting the pension you already have (US health coverage and Social Security: the two ends of the gap). What comes out is a list of moves of equal value, and any honest simulator will build it, by hand if you have to, by rerunning the plan once per lever. The better tools do it for you: the FIRE simulator gives this menu a section of its own (Using the FIRE simulator). Nine times out of ten, it shows the extra year to be the most expensive lever on the list. Priced against the alternatives, "I'll just work more" loses its mental monopoly.

The sloped exit, or partial OMY. The compromise that takes the best of both columns: part-time, a move to contract work, a sabbatical you can convert (Barista, Coast, side income: work you choose, Accumulation, transition, withdrawal: the three lives of a FIRE plan). Half the safety of a full year for half the life postponed, with a prototype of the life after thrown in. For a lot of people the real answer to the syndrome is not "leave now" but "stop counting in whole years".

🧮 Three OMYs, three verdicts

Yasmine, 45, target reached, central failure 3.8%, floor tested, workshop project prototyped. Her "one more year, just to be sure" is the syndrome in its pure form. The menu of equivalences prices that year at 0.2 points of withdrawal rate, against a stock of about 20 full-health years. She rereads the criteria she wrote three years earlier: all green. She leaves, and two years later, exactly as the accounts predicted, she wishes she had left at 43. Karim, 48, central failure 9%, floor at 88% of comfort. His extra year is rational, on the steep part of the curve. But the menu shows better. Two years of part-time work at $900 a month, the partial OMY, buy as much while postponing less. He negotiates a three-day week. Léa, 44, hits her target in the middle of a euphoria (CAPE 36, CAPE anchor, failure 8%). She writes a bounded delay: "18 months maximum, savings parked in money market, early exit if the market falls 20%." That is case two of the rational list, with its backstop date. The syndrome gets no purchase on a delay that has a written end.

The essentials§

The syndrome comes from an accounting asymmetry. The unlikely failure is visible and priced; the certain years lost are invisible and never billed. No number ever "suffices", because the real trigger is a feeling, not a threshold.
The numbers. An extra year buys 0.2 to 0.4 points of withdrawal rate: a lot for the first one on a stretched plan, almost nothing once the plan is sound (the curve flattens). Against that, one twentieth of your stock of full-health years (healthy life expectancy runs to about 64 or 65, the statistic to keep in sight).
Rational OMY exists in three cases: a plan that really is stretched, an exit at the top of a euphoria (a bounded delay with a backstop date), and a life after that is not ready (the year that builds something, with a deliverable). The test is one question, "What will I know in a year that I do not know today?".
The cure is structural: criteria written in advance while calm, with an anti-goalposts clause; the date-or-condition commitment; a menu of equivalent moves priced in a simulator (the extra year is almost always the most expensive lever on it); and the partial OMY as a sloped exit.
The verdict from the field is unanimous (What real FIRE retirees say: accounts and advice): with a plan built to this book's standards, the movement's dominant error is not leaving too early. It is leaving too late.
