Gunnar Alsted retired at sixty-four holding a number he trusted: $2,450 a month, calculated to last thirty years. He treated it as a rule, which is the responsible thing to do with any number of that sort.
So when his daughter proposed a fortnight in Portugal during his second year, he declined. He declined a great many things across those two years, and took quiet pride in the discipline until somebody spelled out what the plan had been assuming all along.
That he would spend precisely as much at sixty-six as at ninety-two. Not roughly. Identically, month after month, across twenty-eight years, through the decade he could still manage stairs and the decade he might not.
A flat plan averages a life that is anything but
Spending across a long retirement rarely holds level. The opening stretch is usually the costly one, being the stretch in which travel, hobbies and visits remain physically possible. The middle tends to quieten without anyone deciding it should. The final stretch can climb again, occasionally steeply, and for reasons nobody would choose.
Gunnar had done nothing whatever wrong. He did precisely what a careful person does with a thirty-year figure, namely treat it as a limit. The difficulty is that averaging something uneven yields a number too tight across the years you can actually use and not obviously right for the years you cannot predict. Splitting the horizon into stretches took him about fifteen minutes.
The fifteen minutes that rearranged the same money
Nothing fresh went in at all. The same savings, the same pension, the same expected span, arranged into stretches instead of divided by one figure.
What came back · in roughly fifteen minutes
an active stretch, a quieter middle and a later one, each carrying its own figure rather than a single average pretending to cover all three.
$530 a month beyond what he had been allowing himself, with the total entirely unchanged. That is a fortnight in Portugal, twice over.
care and health costs swing enormously, and folding them into a monthly figure buries them. Kept separate, they stop bending every other year out of shape.
one date each year for comparing the plan against what genuinely happened, since a thirty-year plan drawn up once is a guess standing up straight.
Portugal happened the following spring. The plan grew no looser; it acquired a shape, and the total beneath it is the one he retired with. He now also holds a date each January for checking it against what genuinely occurred, which he had never had before.
The shaping ladder, rung by rung
Rung 1 · Split the horizon before dividing the money – three stretches rather than one. Dividing first and living afterwards is what produces a figure no actual life resembles.
Rung 2 · Let the active stretch carry more – the years in which travel and visiting stay physically possible are finite in a way the money is not. Underspending them is a decision, and it has a price.
Rung 3 · Keep the later reserve to one side – care and health costs are the least forecastable element here. Spreading them across thirty years buries them inside every other year.
Rung 4 · Fix a review date, once a year – measured against what genuinely happened rather than the original assumptions. A plan reviewed each year behaves nothing like one made once and shelved.
The rung that counted for Gunnar was the second. He had treated the money as the scarce resource, which is reasonable enough, and had missed that the years in which he could spend it were scarcer still.
Why the cautious version costs the most
Because caution carries no visible price tag. Overspending appears in a balance and gets corrected. Underspending appears as two years of declined invitations, and no statement anywhere records it. Gunnar’s plan had never flagged a single problem, because on its own terms none existed.
A second reason deserves naming. One figure held across decades feels like control, and control is worth a great deal to anyone who has only just stopped earning. Here is what earned a place in his plan, and what did not.
- Splitting a long retirement into stretches
- Letting the active years carry a larger figure
- Holding the later reserve apart from the monthly plan
- Reviewing against what happened, once a year
- Treating the years as the scarce resource too
- One monthly figure held flat for decades
- Averaging unpredictable later costs into every year
- Judging a plan only by whether the money lasts
- Making the plan once and never revisiting it
- Reading declined invitations as successful discipline
Sequence is the entire discipline: split the horizon, let the usable stretch carry more, hold the later reserve apart, and review it every year. The total stays put. What shifts is which years it actually reaches.
What it costs beside the alternatives
Gunnar might have reached this alone, and possibly would have eventually, though likely not before the stretch that mattered had gone. Here is how the usual approaches compare with shaping the same total across stretches.
| Approach | Cost | What it does about the shape |
|---|---|---|
| One flat figure for thirty years | Free | Too tight in the usable years, vague about the late ones |
| Spend and hope it works out | Free | No horizon at all, and the reserve never exists |
| A financial adviser | $150–300/hr | The right call for withdrawal decisions, and worth the fee |
| Retirement Income 30-Year Plan | $10 | The same total, shaped into stretches, with a review date |
“Does spending more early not sound reckless?” It would be, were the total rising, and it is not. What is being described is the same money arranged differently, with a reserve held back and a date every year to check it against reality. That said, this is the part of the article where a caveat is genuinely needed rather than decorative. How long savings last depends on markets, on how long you live, on health, on tax and on rules that differ by country and by scheme, and none of that is predictable from an article. Actual withdrawal decisions are exactly what a licensed adviser is for, and the fee is usually worth paying at this stage of life. This is general educational guidance about the shape of a plan, not financial, tax or retirement advice, and no figure here is a recommendation.
Two more who stopped living on an average
“I turned down my grandson’s wedding trip because it was not in the monthly figure, and the figure was the same one I will be on at eighty-eight. Written as three stretches instead of one, it was affordable and always had been.”

“My worry was the opposite one, that I would spend the good years and leave nothing for the difficult ones. Setting the later reserve aside first was what let me stop rationing every ordinary month.”

If the question underneath is still whether the date itself was right, the Retirement Readiness Planner is built for that instead. Results vary; this is general guidance and not financial or retirement advice.
Five short answers, and the same total lands arranged rather than flattened: three stretches in place of one figure, what the active years could carry without the plan shifting, and a reserve held apart for whatever nobody can forecast. It recommends no product and replaces no adviser. What it hands you is the shape, which tends to be the part nobody has examined.
