Deferring your Finnish pension
See how much your pension grows if you keep working past your earliest retirement age, and when the deferral has paid back the months you skipped.
Checked by Radif Partners · Editorial policy · Calculation method
Each month you postpone your earnings-related pension beyond your earliest retirement age raises it by 0.4%, so a year’s deferral means a permanent 4.8% increase (lykkäyskorotus). The increase applies to the pension accrued up to the end of the month before it starts, and while you keep working your salary accrues new pension at 1.5% on top. With a pension of €1,900 a month at your earliest age and a year more on €3,000 a month, you would retire on about €2,036. The catch is the €22,800 of pension you did not draw that year; the larger pension needs about 14.0 years to earn it back, ignoring tax and indexation. The target retirement age is set so that deferral exactly cancels the life expectancy coefficient: 15 months for people born in 1964. Kela raises the national pension by 0.4% per month of deferral for anyone born in 1962 or later. Deferral can run until the upper retirement age.

What the increase is based on
The Employees Pensions Act raises an old-age pension by 0.4% for each month its start is postponed beyond the calendar month after you reach your earliest retirement age. The increase is calculated on what you had accrued by the end of the month before the pension starts; new accrual from salary during the deferral, 1.5% of annual earnings, is added separately.
It is a permanent percentage, not a one-off bonus. It stays with the pension and is indexed every year like the rest of it, so its real value depends on how many years you end up drawing the pension.
Deferral in numbers
The example assumes a pension of €1,900 a month at your earliest age and a salary of €3,000 while you defer. The last column shows how long the higher pension takes to make up for the pension you did not draw.
| Deferral | Increase | New accrual | Pension after | Pension not drawn | Break-even |
|---|---|---|---|---|---|
| 6 mo | 2.4% | €23 | €1,968 | €11,400 | 14.0 y |
| 12 mo | 4.8% | €45 | €2,036 | €22,800 | 14.0 y |
| 24 mo | 9.6% | €90 | €2,172 | €45,600 | 14.0 y |
| 36 mo | 14.4% | €135 | €2,309 | €68,400 | 14.0 y |
| 60 mo | 24.0% | €225 | €2,581 | €114,000 | 14.0 y |
Break-even is the same on every row, because both the pension you skip and the increase you earn grow in direct proportion to the months deferred; real pay rises and indexation shift it only slightly. The real question is how long you expect to draw the pension, not on deferring one year rather than three.
After tax
In Helsinki without church tax, €1,900 gross leaves €1,632 net. After a year’s deferral, €2,036 gross leaves €1,731: the gross gain of €136 becomes €99 net, because the increase lands in your top slice of income where the pension income deduction is being phased out. The pension you skipped would have been taxed too, but at your average rate, while the increase is taxed at the margin. On net figures you forgo €19,582 and gain €99 a month, a break-even of about 16.5 years.
Target age: deferral against the coefficient
For the 1964 cohort the life expectancy coefficient of 0.94643 trims about 5.4%. The target age of 66 years 3 months is 15 months after the earliest age, worth 6.0%. Because the coefficient is applied first and the increase on top, the pension at the target age ends up slightly above the uncut amount. Ages by cohort are on retirement age; coefficients on life expectancy coefficient.
One person, four start ages
Our pension engine works through a single case: someone born in 1964 with €2,000 a month accrued at the start of 2026 and a salary of €3,500. The table applies the 0.94643 coefficient, the deferral increase and new accrual.
| Pension starts at | Accrued before coefficient | Deferral increase | Monthly pension |
|---|---|---|---|
| 65 | €2,164 | €0 | €2,048 |
| 66 y 3 m | €2,232 | €123 | €2,236 |
| 67 | €2,273 | €197 | €2,348 |
| 70 | €2,438 | €492 | €2,798 |
At the target age the pension is €188 a month higher than at the earliest age; working to the upper age adds €750. Most of that comes from the deferral increase (€492), not from five extra years of accrual (€273 before the coefficient).
Deferral is a bet on a long retirement. If your health is poor or the job is wearing you down, retiring at the earliest age or taking a partial early pension may serve you better. It pays best when you enjoy the work, earn well and have an above-average pension already accrued.
Kela and small pensions
The Kela national pension can be deferred too, at 0.4% a month for those born in 1962 or later. But it shrinks by half of any earnings-related pension above €66.54 a month. A single person with €600 of earnings-related pension gets €520.32 from Kela; after a year’s deferral of the earnings-related part only, Kela pays €505.92 and the total rises by just €14.40.
The mirror image is the partial early pension, where the same 0.4% per month is deducted instead of added. The pension calculator lets you set your own start age and see the effect.
