Working one extra year can improve retirement readiness in several ways at once. You may add a contribution, leave the portfolio invested, fund that year’s living costs from salary, delay the first withdrawal, and shorten the funding horizon. Compare the complete paths so you count each effect once.
Count the complete change
Use one of two lenses:
Balance sheet
Compare assets one year from now if you retire today or work one more year. Include returns, contributions, withdrawals, and taxes in both paths. The difference is the extra wealth held by the work path.
Retirement capacity
Compare the spending each balance can support over its remaining horizon under the same assumptions. The later retirement has one fewer year to fund. Keep this result separate from the balance-sheet result because both describe the same decision.
Suppose you have €800,000 invested, can save €30,000, and would spend €40,000 during the first retirement year. Assume a 5% return in both paths and a year-end withdrawal:
The work path ends the year €70,000 ahead: €30,000 of new savings plus €40,000 of avoided withdrawals. The return on the original balance does not create the difference because both paths received the same return.
If both paths keep the starting portfolio invested, count its return in both. Compare the contribution and avoided withdrawal when measuring the end-of-year wealth difference.
See how age changes the result
A second lens values one fewer year of withdrawals. Under a constant real-return model, the capital required for a fixed spending stream is:
This formula isolates the effect of reducing the funding horizon by one year. It does not predict a safe withdrawal rate because real markets produce uncertain returns.
Consider two simplified cases with a 3% real return and a €30,000 contribution:
At 40, the model moves from a €600,000 portfolio and a 50-year horizon to €648,000 and 49 years. At 55, it moves from €1.2 million and 35 years to €1.266 million and 34 years. The later example gains more euros because the starting portfolio is larger. Your result will depend on contributions, spending, pension dates, taxes, and market returns.
Add pensions and sequence risk
A further year can increase a future pension or move you closer to eligibility. Enter that change as future income in the years when you expect to receive it. For example, an extra year of service might add €1,500 a year from age 67. Its value depends on the start date, tax treatment, and payment period.
A later retirement can also lower the first withdrawal rate. With €950,000 and €40,000 of planned spending, the initial withdrawal is about 4.21%. If another year takes the portfolio above €1 million, the same spending uses a smaller share of the balance. You also avoid one year of portfolio withdrawals before retirement.
The extra capital helps with sequence risk, but it does not remove it. Test the retirement date against an early market decline, spending cuts, large one-off costs, pension gaps, and cash needs.
Find your stopping point
Compare three scenarios:
- Retire now.
- Work one more year.
- Move through a part-time transition.
Hold the lifestyle assumptions constant. Check sustainable spending, the result after an early decline, cash after planned large expenses, future income gaps, and the flexibility each path requires. You may find that one extra year sharply reduces the cuts needed in a weak scenario, while a second extra year mainly increases ending wealth.
Fignis can make that comparison concrete.
The model can put euros beside another year of work. It cannot price the year itself. Use the numbers to understand the trade, then decide how much financial margin your time is worth.
