How much difference does working a few years longer make?
Working longer is the most powerful single lever in a retirement plan, and it is the least popular. A year of extra work adds a year of contributions, removes a year of withdrawals, shortens the bridge to the State Pension, and gives the pot another year of growth — four effects that compound rather than add.
- Contributions: another year of them, including any employer match.
- Withdrawals: one fewer year the portfolio has to fund.
- The bridge: one year shorter, which is a year of full spending removed.
- Growth: another year of compounding on the whole pot.
01 Four effects at once
Contributions continue for another year, with whatever employer match comes with them. The portfolio is not drawn on for that year. The bridge to State Pension age is a year shorter, removing a full year of spending from what savings must cover. And the whole pot compounds for another year.
Those effects multiply rather than adding, which is why the total is so much larger than the salary earned. On a typical plan a single extra year moves the sustainable income by more than several years of increased contributions would.
It also works in reverse, which is why stopping early costs so much more than the salary forgone.
Shows: the difference one extra year of work makes to a pot, against a year of retirement instead. Ignores: tax, inflation, the State Pension, and any scheme pension.
On the defaults above, the worked example shows £38,480. One year of work leaves the pot £38,480 larger than one year of retirement — and the bridge to the State Pension is a year shorter as well.

02 The other things a year buys
A qualifying National Insurance year, if the record is short. At about £358 a year of State Pension for life, that is worth more than most people attribute to a single year of work.
Time for markets to recover, if the plan is being made after a fall. Retiring into a drawdown at the bottom of a market is the worst version of sequence risk, and a year of flexibility on the date is a genuine defence against it.
And information. A year closer to the date means better estimates of spending, health and family circumstances, all of which are guesses at five years out.
03 Part-time counts
The four effects do not require full-time work. Reduced hours keep contributions running, delay or reduce withdrawals, shorten the bridge and preserve the National Insurance record — at a fraction of the personal cost.
Three days a week for four years does most of what one more full-time year does, spread over a longer period, and it is a much easier thing to agree to. Phasing is the version of this that people actually accept.
The obstacle is usually the employer rather than the arithmetic, and the request costs nothing to make.
Nobody wants to hear this and it is the largest lever in the whole plan. One extra year adds a contribution, removes a withdrawal, shortens the bridge by a year and compounds the whole pot for another twelve months — four things at once, which is why it beats several years of saving harder. It also buys a National Insurance year if your record is short and time for markets to recover if you are deciding after a fall. And it does not have to be full time: three days a week for four years does most of the same work.
FAQ
Why does one year make such a difference?
Because four effects stack: another year of contributions, one fewer year of withdrawals, a bridge to the State Pension that is a year shorter, and another year of compounding on the whole pot.
Is it better than saving more?
Usually, and by a wide margin. Increasing contributions affects one of the four effects; working a year longer affects all of them, which is why a single year commonly beats several years of harder saving.
Does part-time work count?
Yes. Reduced hours keep contributions running, delay or reduce withdrawals, shorten the bridge and preserve the National Insurance record. Three days a week for four years does most of what one more full-time year does.
