Of course, you can also calculate your approximate severance payment yourself. In principle, two basic requirements should be met when calculating the severance payment, for example after a dismissal:
1.) Length of service longer than 6 months (probationary period ended) → You can find more details on why this is the case here (Dismissal Protection Act)
2.) Number of employees in the company more than 10 → more information on protection against dismissal in small companies
3.) If notice of dismissal has already been given, the notice of dismissal must not have been received more than 3 weeks ago → more information on missing the deadline for filing a complaint after a dismissal
If these points are met, you can use the following formula to calculate the standard severance payment
Standard severance payment = factor 0.5 * monthly gross salary * years of service with the company
In addition, some more information on the monthly gross salary. The following forms of remuneration are also included here:
