Your pension benefit increases as a percentage as you earn more?
We have a similar situation in Sweden. For white-collar pension setups the employer contribution is normally (or "often but not always") 4,5% of the salary up to a certain point, and 30% of the salary above that. The reason for this "knee" in the curve is that the public pension system built in to the tax system stops adding more pension benefits at that knee. So to "ensure" that people get a pension that is closer to a certain percentage of their working income, the employer contributions increase when the public pension stops increasing.
The reason why I said "most but not always" is that this is based on the collective bargaining agreement in place for white collar jobs here in Sweden and companies who are not a part of those agreement often follow that model anyway. Blue collar unions have negotiated a slightly different setup for them if I understand correctly.
So the total salary cost for an employer in Sweden is typically:
- Normal pre-tax salary (which is taxed between 30% and 58% before it reaches the person)
- "Social fees" or "Employer fees" or 31,42% of the pre-tax salary (this includes the tax based pension contributions)
- Pension contributions of at least 4,5% of the pre-tax salary to private solutions, typically in insurance companies where the employee can select his own funds to invest in.
This means that for a high earner, an increase in base salary of 1000 SEK will cost the employer 1000 + 314 + 300 = 1614 SEK, while only 420 SEK will end up in the bank account of the employee (and 300 in their pension account, less fees from the insurance companies)
Then there are other more hidden costs for the employer like vacation rights (minimum 5 weeks / year), illness (where the employer pays for the first two weeks, basically and then the government takes over) and a bunch of more or less mandatory insurances.
( For any swedes reading this, the model I refer to is the defined contribution model of ITP1. If you're old enough and work at a company that uses the defined benefit-model of ITP2, the employer contributions to the pension system can be significantly higher. )
