If you make 1M SEK/year (~100k USD) you are in the very very very top of IC’s in Sweden, and your salary post-tax is roughly 68k USD.

Of course you can save a good chunk. Save roughly half, and still have the median post-tax salary.

(And you can save in a less taxed private retirement scheme which can be drawn from at age 55, but at the same time there are implications of not working at the end of your career for the government sponsored pension)
