Question 1

What is 'one more year syndrome' in retirement planning?

Accepted Answer

One More Year (OMY) syndrome describes the pattern of people who have already reached their financial independence number continuing to work for additional safety margin — then repeating this annually. It's driven by loss aversion (fear of running out of money) and identity (work = purpose). Each additional year provides diminishing risk reduction while consuming a disproportionate amount of remaining healthy life years.

Question 2

How much does one extra year of work actually change my retirement security?

Accepted Answer

At a typical safe withdrawal rate (3.5–4%), one additional year of work: adds approximately 20–30× your annual savings to the portfolio, reduces your withdrawal period by 1 year, and increases your SWR safety margin by roughly 0.1–0.2 percentage points. Whether this marginal safety is worth one year of your finite healthy life is a personal calculation — this tool shows you the numbers explicitly.

Question 3

At what point does working longer actually not improve retirement security?

Accepted Answer

Research by ERN (Early Retirement Now) on CAPE-based SWR suggests that once your portfolio covers 25–30× annual expenses (3.3–4% SWR), additional years of work provide very small incremental security. The sequence-of-returns risk that drives retirement failure is largely insensitive to starting 1–2 years earlier vs. later, but is very sensitive to withdrawal rate.

Question 4

Is it rational to want 'one more year' of safety?

Accepted Answer

To a point, yes — rational risk aversion is healthy. The syndrome becomes irrational when: you have clearly exceeded any reasonable safety threshold, the additional year produces less than 0.2% SWR improvement, or you are consistently trading healthy life years for financial margin you'll never need. This calculator helps you see where on that spectrum your specific situation falls.
