Should I Work One More Year? How to Price the Decision

"One more year" is the default answer to retirement anxiety. It's so common the early-retirement crowd gave it a name — one-more-year syndrome. And here's our honest opinion: it's usually bought blind. People often pay a year of their most active retirement time for a safety margin they rarely measure.

TL;DR: One more working year changes a plan in four concrete ways — more saved, one less year of withdrawals, one less year to fund, and sometimes a bigger CPP payment. All four can be calculated. For some plans a year is transformative; for others it barely moves the needle. The practical way to find out which kind is yours is to run both dates and compare.

What one more year actually buys

Four things happen when you push retirement out a year, and each one is arithmetic, not mystery:

1. One more year of contributions. Salary in, RRSP and TFSA room used, employer match collected if you have one.
2. One less year of withdrawals. The portfolio isn't just bigger — it's untouched for a year, often the biggest of the four effects.
3. A shorter retirement to fund. The age you're planning to doesn't change; the number of retirement years your savings must cover shrinks by one.
4. Sometimes, better CPP. An extra earning year can displace a low-earning year in the calculation, and if you also delay the start past 65, the 0.7%-per-month deferral bonus stacks on top. The size of this effect varies a lot by earnings history.

Stacked together, these can move a marginal plan into comfortable territory. That's why the instinct exists — it's not irrational.

What it costs

A year. Specifically, a year of what our spending-phase model calls the active years — the stretch where travel, sport, and energy-hungry plans are most realistic. Retirement spending research tends to show spending declining with age; for many people, the years given up at the front are worth more, in lived terms, than the ones protected at the back.

There's also a subtler cost: "one more year" has a habit of becoming two, then three, partly because it's rarely measured. Without a number attached, the anxiety that motivated the first delay tends to still be there after it.

How to price it

It helps to treat this as a comparison rather than a feeling: run the same plan twice — retirement this year versus next year — and look at three outputs:

• Plan survival. Does the extra year change whether the money lasts as long as you're planning for, or just add padding to a plan that already works?
• The dollar difference. Total lifetime spending and what's left for your estate — sometimes the gap is large, sometimes it's a rounding error.
• The stress-test gap. When markets turn bad early, does the extra year meaningfully cut down the scenarios where the plan runs short? This is where a year of buffer earns its keep, when it earns it at all.

If the two runs are nearly identical, you've learned the year is optional — which is a different decision than "necessary." If they're far apart, you've learned the anxiety was pointing at something real. Either way, you've priced it — and a priced decision usually beats a blind one.
