Law / Tax calculator (netto/brutto earnings) in Poland? [10]

[Moved from]: Calculating Taxes in Poland, any website?

Hallo, very simple question: is there a website calculating out of your monthly salary how much goes away in taxes (social security included)?
How progressive is the current system, what's the different % someone making 4000, 8000, or 16000 per month has to pay, for instance?

Work / Average monthly salary in Poland is around 1000 PLN (few hundred bucks). [387]

I just moved to Warsaw, walking around the center and just watching people have fun they actually don't look like people making 3k net, more like 7-8k at least.

Otherwhise I wouldn't see so many people wearing LaCoste or Ralph Lauren polos or Armani Jeans. Not everyone, but the proportion is not too different from the one I find in other cities in Europe.

Weird...

Real Estate / PLN 2,500 the going rate for an apartment in Poland [210]

I'm currently looking for an apartent in Warsaw, I've been offered a few flats in the area between the Palace of Colture and the Arkadia Shopping Center, 50-55m2, furnished, new buildings, bills paid, security and underground garage more or less around the 2500pln per month.

Just for reference, a similar apartment in Milan would easily cost at least twice that money, all included.
The avg salary in Italy is 21k$ while in poland 13k$.

I don't think an average polish worker can afford a 2500pln apartment, at the same time an average italian can't affort a 1300€ one.

Aren't there alternatives in the suburbs?
