Which leaves base pay, I assume the 200k in Berlin were choosen to make the comparison easier. On the surface, lower base pay in Berlin is offset by lower living costs, especially housing (I am aware Berlin is getting more expensive, it is still far from SV so).
Just shows that money isn't everything.
The calculator I used also included payments for social security and medicare contributions, which you would use if you eventually fell below security security income bracket (knock on wood) or if you need medical as a senior (I believe age 65+)
For other health coverage, that is paid for by the employer so also wouldn't come out of your compensation.
Which is fine if you're comparing equivalent "headline" numbers. But for other purposes the ratio of take-home pay to what the employer has to pay out (so including all the employer-side taxes) might be more relevant in terms of determining your likelihood of receiving a certain level of take-home pay.
And yet incomes are much higher in the US than in Germany.
I think headline numbers are the only useful thing to compare here.
