Minijob & Midijob
Pay up to the marginal-employment threshold (Minijob) and within the transition band above it (Midijob) follows its own contribution rules. The calculator deliberately does not price this range – it explains it, rather than showing a wrong number.
What this calculator computes – and what it does not
The gross-to-net calculator on this site is built for regular employment subject to social insurance – jobs with a monthly gross wage above the transition band (§ 20 para. 2 SGB IV), whose upper edge currently sits at €2.000 a month. In that range the employee pays their standard statutory share of social insurance on the full gross wage, and that is exactly the case the calculator models.
When the regular monthly wage falls below it, a different set of legal rules takes over: the Minijob (marginal employment under § 8 SGB IV) and the Midijob in the transition band (§ 20 SGB IV). Neither follows the plain percentage deduction a standard calculator applies – which is why the calculator deliberately does not price the range but explains it. A rough percentage here would simply be wrong.
The Minijob (marginal employment)
A Minijob is low-paid marginal employment: the regular monthly earnings do not exceed the marginal-employment threshold, which currently stands at €603. This threshold is not a fixed euro figure but is tied by statutory formula to the minimum wage (currently €13,90 per hour) – it moves up automatically as the minimum wage rises.
In a Minijob the employer pays flat-rate levies (Pauschalabgaben) to the Minijob-Zentrale – for health and pension insurance and a flat tax. The employee, by contrast, normally pays no contributions of their own to health, long-term-care or unemployment insurance. The exception is pension insurance: it applies in a Minijob by default, so an employee contribution is due – but you can be exempted from it on written request (Befreiung von der Rentenversicherungspflicht).
For a standard calculator this means there is no fixed employee percentage to apply here. Whether any contribution is due at all depends on whether that exemption was requested – a detail this calculator does not know.
The Midijob (transition band)
Above the marginal-employment threshold the transition band begins – colloquially the Midijob. It runs from the Minijob threshold (€603) up to the upper edge of the transition band, which is written into the statute as a fixed amount and currently sits at €2.000 a month. Unlike the Minijob threshold, this ceiling is not a formula but a fixed figure the legislature sets directly, which is why its current level has to be re-checked at each update.
The transition band is meant to cushion the jump from largely contribution-free work into full contribution liability. To do so, the employee does not pay the full contribution straight away: their contribution is worked out not on the actual gross wage but on a reduced, sliding assessment base set by a statutory formula. That base starts near zero at the lower edge and climbs steadily to the full wage at the ceiling – hence the name Gleitzone (sliding zone). The employer pays their normal share on the actual gross wage.
This is exactly why net pay in the transition band cannot be estimated with a simple percentage: the assessment base is itself the output of a formula linked to the year's average total social-insurance contribution rate. An ordinary standard deduction would overstate the employee's contribution substantially in the lower part of the band.
Your wage falls in the Minijob or Midijob range
A monthly gross up to the upper edge of the transition band (€2.000, § 20 para. 2 SGB IV) is calculated under a different, non-linear mechanism from regular employment. This calculator is scoped to regular employment above that edge, so it deliberately does not guess a number here rather than show a wrong result. For a reliable figure in this range, the Minijob-Zentrale and the official Midijob calculator are the right places to turn.
