Cost of Living in Zurich

If you can avoid Zurich, avoid. Try finding an apartment for rent. Good luck. Unless your apartment is being provided by your employer or you have insider knowledge and connections - forget about it. If you are obliged to work in the city of Zurich and do not want to commute extensively, make sure your monthly salary is at least 8-10k/month and if you come with your family make sure the houshold income is at least 15k/month. As mentioned here already - health insurance which is compulsory in Switzerland and which you must pay yourself sets you back at least 500/month/person. So for a family of 4 that's already 2k/month. If you actually use the health care system that's another 2.5k per year/person out of your own pocket. Zurich is ok for high earners or dinks, otherwise look elswhere. There is one exception though - education at all levels is very good and all schools run by the gvt are free or almost free at the higher education level. There are also great private schools (which cost of course).
In summary, if you come with your family, make sure you get benefits or support from you employer especially in housing and plan to stay for a longer period of time. Send your kids to state run schools as they are high quality and free of charge.
I lived in Zurich from 1977 until 1993 and obtained my higher education there. Even then I hated the place and got out as soon as I could. I never looked back and wouldn't consider living there again, even if I could afford it. Although Zurich is a very clean city with lots of parks and publiy areas and nice forests directly at the city limit, the weather generally sucks. Winter months especially are super dreary as the city is often covered for weeks by high inversion fog (a cloud layer that does not dissolve). Above that cloud layer sunshine often prevails. So you're forced to work in winter gloom knowing that a few hunderd feet higher up the sun is shining. Think carefully before you move to Zurich.

Omg, i did not know that the situation in Swiss land is so dire, super expensive health insurance, 7000 CHF per year and partial coverage only. Not so good quality health care and long waiting times, it is like hell.

In real life, prices in Switzerland are much higher than mentioned here.

I found out the hard way...

Zurich, Basel, Bern is only cheap when you make over $120.000 a year.

Prices in Switzerland are on average double that of countries like Spain, Germany, Netherlands, Luxembourg.

The expense are grossly inflated. It indicates what I would call a boomer attitude, buying premium groceries and going out for restaurants, exhibitions, multiple times a week, always using expensive convenience options (taxis, cleaning maids, fiduciary), magazines/clubs/entertainement subscriptions, etc. instead of the more normal, regular, humble life that 75% of swiss have that doesn't have all of this.
I kept my student lifestyle that was very quality aware, yet budget conscious. I looked to have all my needs filled and have comprehensive QoL features (unlimited data/calls, Public Transport Pass, optic fiber internet, lots of vegetables, fruits, seeds, nuts, cheese, meats, etc), a bike, going out with friends and having decent clothing, performant electric devices and appliances. It costs half of what it is.

Switzerland is not about spending your money, but about wasting your money. It's just not worth it, for what you get.

No foreigners are ever appreciated or needed in the USA.It was your choice not the USA who asked you to move there in the first place.You should've stayed in your motherland as you call it since you didn't report over $10,000 USD in your bank accounts in Switzerland.You're lucky the U S government didn't throw you in prison for 5 years and fine you $250,000 usd.
You paying taxes working in the USA is something everyone does.Consider it a payment just to live in the richest place in the world and the most powerful too.

Instead of appreciating foreigner who worked and contributed in US and holds merely either US permanent resident visa(green card) or US work visa before but they are not a US citizen and still hold the citizenship from their motherland.

Now the zombielike US thief government is brazenly punishing and scamming all of the aforementioned foreigner in their own motherland outrageously for not declaring/reporting their own bank accounts from their motherland with the least punishment of whopping 10,000 US dollar for each of their motherland bank account to the extent of confiscating half of their life savings outrageously and inhumanely.

Even worse, instead of standing with their people, their respective inhumane government from their own motherland supports the zombielike US thief government to not only freeze their own bank accounts but also rob ten of thousand of US dollar from their accounts outrageously in their own motherland.

The greatest tragedy for the humankind is happening now under the manipulation of the US thief government, thanks for all of the hypocrite countries who made it happen now by supporting the US thief government against their own blood brother and blood sister and bringing the worse future without justice for their respective future descendants.

The wealth of the people is as much as the same as the wealth of the country but allowing the zombielike US thief government to rob the wealth of your people is the greatest treason against the holy blood of your own that you share with your people.

The greatest injustice inflicted to the aforementioned foreigner by the zombielike US thief government is unforgivable until the day the US thief government is toppled.

It's time for all countries to be united to protect the interest of the citizen of their own respective country by destroying the zombielike US thief government by banning the most untrustworthy US dollar which is good for nothing but dragging the rest of the world for getting worse and worse with the most untrustworthy US dollar printer which overprints the most untrustworthy US dollar paper without any accountability to the extent of creating the most unsustainable debt of over 30 trillions US dollar for the most immoral US thief government until so far.

how much is the rent for an apartment in the centre? (minimum of 90 square meters). Is 16K CHF enough to live there with high quality life? how much I can save from this?
