There are PhD positions which I am interested in being advertised at Aalto University, offering 2400 euro per month salary. Can anyone advise on:
1. is this reasonable salary to live on my own walking distance to university?
2. would I be able to save any of this money? (maybe even potentially mortgage a house?)
3. rough tax calculation? (any discounts for students)
4. do salaries increase normally after the first year for doing PhDs in Finland?...(I have heard they may add bonus depending on personal performance)
5. any other general standard of living / life as foreigner tips / loneliness of PhD (

So I looked around a lot of forums, there are numbers thrown around, but I am totally confused, different opinions, different locations! The tax calculator tool (Vero Skatt) seems super confusing for me as well. I did look up properties around the area, and it doesn't seem too expensive (like Helsinki).
Any advise / opinions would be highly appreciated, especially if you live around this area.
P.S. I live in London (so comparisons are welcome!)
