A lifetime earnings profile is the shape income takes over a working life, not a flat line. Typical Lebenseinkommensprofil (lifetime earnings profile) shapes show steep growth in the first 10-15 years of a career, a plateau in the middle years, and sometimes a late-career decline. The shape differs systematically by education path, not only by the starting salary.

Why it matters

Comparing two careers, or two education paths, by starting salary alone misreads the profile. A lower starting salary paired with a steeper slope can overtake a higher starting salary with a flatter one — the question is not "who earns more this year" but "who earns more cumulatively by which age."

The fork between a Studium (university degree) and an Ausbildung (vocational training combining paid on-the-job training with part-time vocational school) is decided at money-day-zero on exactly this logic. An Ausbildung path starts earning years earlier and often reaches a higher wage sooner, but a Studium path frequently starts later and lower, then climbs faster once qualified. Whether one path overtakes the other, and when, depends on the slope difference — not on which one "pays more" at age 20.

Worked example

The figures below are illustrative only — a simplified shape to reason with, not measured statistics for any real profession.

Age	Ausbildung path: cumulative gross earnings	University path: cumulative gross earnings
18	€28,000 (year 1 of paid training)	€0 (studying, no income)
22	€130,000	€0 (still studying)
25	€230,000	€60,000 (first 2 years post-degree)
30	€400,000	€380,000
35	€580,000	€650,000

In this illustration, the Ausbildung path has a four-year head start and a steady early climb, while the university path earns nothing during study but grows steeply once it begins — the two cumulative totals cross somewhere around age 30-32. Real crossover points vary by field, region, and individual career trajectory; the table shows the mechanism (a head start against a steeper slope), not a claim about any specific occupation.

The same mechanism explains why a career break costs more than the visible monthly gap. A break taken during the steep early-career segment removes not just the missing salary during the break, but also delays entry into the higher-earning plateau — the lost years shift the entire later curve outward.

Check yourself

Which statement best describes a typical lifetime earnings profile?

Income grows at roughly the same euro amount every year from career start to retirement.Income typically grows steeply in the first 10-15 years, then plateaus, and sometimes declines late in the career.Income declines steadily and predictably from the first paycheck onward.

Using the worked example: at age 25, the Ausbildung (vocational training) path shows illustrative cumulative gross earnings of `€230,000`, and the university path shows `€60,000`. What is the illustrative gap between the two paths at that age, in euros?

Why can a one-year career break taken early in a steep part of the earnings profile cost more than the visible 12 months of missing salary?

The break only removes the salary paid during that year — the visible 12-month gap is the full cost.The break shifts entry into the steep-growth and plateau segments later, so the whole subsequent curve is delayed, not just the missing months.Employers always add a fixed penalty period equal to twice the length of any break.
