Pension gap: what is missing between your needs and the statutory pension

The pension gap is the difference between what you need in retirement and what the statutory pension pays out. It is the reason the Altersvorsorgedepot exists at all. The decisive figure is not in your pension statement, because inflation is missing there.

What is the pension gap?

Two figures face each other. On one side your needs in retirement, on the other the statutory pension. What is missing in between is the gap. It has to be covered from private or occupational capital.

Needs do fall in old age. But less sharply than many expect. Work-related expenses disappear – commuting, work clothes, lunch out – and anyone past the family phase also saves everything the children used to cost in the household. On the other hand other items rise, above all health and housing. Around 80 percent of the last net income has become established as a starting point.

Why does it hit younger people harder today?
The pension level has been falling for decades while life expectancy is rising. Anyone who is forty today has to live longer on less than the generation before.

How to estimate it

For a first assessment three steps are enough, and you need neither an advisor nor software.

  1. Take your current net income and calculate 80 percent of it. That is your estimated need.
  2. Look at your pension statement. The amount stated there is gross; deduct roughly 15 percent for taxes and social security contributions.
  3. The difference is your monthly gap in today’s purchasing power.
Current net income Need (80%) Net pension (rough) Gap
€2,200 €1,760 around €1,050 around €710
€2,800 €2,240 around €1,340 around €900
€3,500 €2,800 around €1,680 around €1,120
€4,500 €3,600 around €2,050 around €1,550

Rough calculation, assuming a net pension level of around 48 percent of the last gross income. Individual employment histories deviate considerably.

Anyone who wants to know more precisely uses the pension gap calculatorwhich takes account of age, income and the planned start of retirement, and factors in inflation.

Why the pension statement is misleading

Your pension statement shows an amount that looks reassuring at first glance. Three things are missing from it.

First, the figure is gross. Statutory pensions are subject to tax, plus contributions to health and long-term care insurance, so that between ten and twenty percent comes off the stated amount depending on your situation before anything even reaches your account. Second, it is given in today’s euros even though you will receive it in thirty years. At two percent inflation a euro will then have about 55 cents of purchasing power. And third, the projection assumes that you will carry on earning as you did most recently, without interruption, until you retire.

The uncomfortable calculation: A pension of €1,800 in thirty years corresponds, at two percent inflation, to today’s purchasing power of around €990and at three percent it is only around €740.

What it costs to close it

To get €700 a month in supplementary pension over around 20 years, you need roughly €170,000 in capital at the start of retirement. What that means for your contribution depends almost entirely on when you start.

Starting at Years to 67 Required contribution at 6%
25 42 around €75
35 32 around €145
45 22 around €310
55 12 around €810

Model calculation, 6% nominal, excluding costs, allowances and taxes. Target capital €170,000.

Ten years of delay roughly doubles the contribution. Every time. That is the real reason everyone always urges haste on this subject, and for once the warning is justified. The government subsidy in the Altersvorsorgedepot lowers the amount you have to put up yourself even further, because Allowances grow along with it from the very first year.

Three examples

Lena, 27, preschool teacher, €2,200 net. Her estimated gap is around €710 a month. With 40 years remaining, a contribution of about €80 is enough, with the basic allowance covering a considerable part of it.

Markus, 46, sales, €3,500 net, nothing put aside so far. Gap around €1,120. With 21 years remaining he would have to put up about €540 a month. More realistic for him is to lower the target and work longer.

The Hoffmanns, both 38, €5,200 net between them, two children. They reckon with a combined gap of around €1,700. Across two securities accounts and the full child allowance they cover a large part of it with government money.

Frequently asked questions about the pension gap

Are 80 percent of net income really necessary?

It is a rule of thumb, not a law. Anyone living rent-free gets by on less. Anyone wanting to travel a lot in old age needs more.

Does the occupational pension count towards it?

Yes. Everything that comes in regularly in retirement reduces the gap. Occupational pension, existing Riester contract, rental income.

What is the net pension level?

The share of the standard pension in average earnings, after social security contributions and before tax. It serves as a political control variable, not as a personal forecast.

Do I have to factor in inflation?

Absolutely. Without an inflation assumption, every retirement plan looks better than it is.

What if I am too late?

Then other levers apply: work longer, lower the target, use one-off payments. Giving up is the worst of these options.

How often should I recalculate?

Every three to five years and after every major change, such as a jump in salary, part-time work or a new addition to the family.

What should you take away?
The pension statement gives a gross figure in today’s purchasing power. What actually arrives is considerably less, and the only effective lever against that is time.
