Typical freebies in Germany include:
- 13th salary as a Christmas gift (so +8.3% salary)
- only half of your health insurance costs are included in the nominal salary
- tax refunds if you buy a PC, do courses, or drive to work with your car
- company pays for children's daycare
- government-backed retirement fund with generous payouts. If you pay in 83€ per month now you can expect to receive at least €450 per month later.
Also, with a bit of searching, you can rent a house with garden for €2000 per month even in large cities like Hamburg or Berlin. As a result, an 100k€ annual salary will be enough for you alone to comfortably bankroll a family of 5 - something that's almost impossible in the bay area due to high rents and insane costs of living.
