The most common formula to calculate the amount of the redundancy package is the 'kantonrechtersformule'.

Amount of the redundancy package = A x B x C

Part A (= number of the weighed years of service)

The first part is the number of the weighed years of service. For the calculation of A the years of service are rounded off at whole years. This means that a period of 6 months and 1 day is treated as a whole year. After that the years of service are weighed. This means that the older the employee is the more important a year of service will be.

For every year of service	Weighing factor
Till age 39	1
From age 40 till 49	1.5
From age 50	2.0

Part B (= gross payment per month)

The second part of the formula is the gross payment per month which consists out of several parts. Some of them or relevant for the calculation of the redundancy package and some are not.

Relevant	Not relevant
Gross monthly salary	Employers part pensionpremium
Holiday allowance	Company car
Thirteenth month	Tantieme
Structural profit share	Non structural profit share
Structural overtime	Employers part healthinsurance
Structural nightshift allowance	Expenses allowance

Part C (= correction factor)

The third part of the formula is the correction factor which is the variable part of the formula. The amount of the redundancy package can be adjusted because of special circumstances. Normally part C is fixed at 1. But when the employer is to blame that the employee has been made redundant then part C can be fixed at 1.5 or even 2. When the employee is to blame then part C can be fixed at 0.5 or 0 when the employee decides to quit himself.
