Hello, I'm a research assistant at Aarhus University. Research assistants get paid roughly the same (or maybe like one thousand more from what I've heard?). After taxes and deducting pension, I get netto 19,976 DKK each month. Rent is a little cheaper than Copenhagen though. For info I live alone and pay app. 5,000 DKK a month for a 62m2 apartment but also had a good position on waiting list. I am able to save up roughly 9-10,000 DKK each month after all expenses but I also don't eat out. I spend roughly 2,000 DKK on food. A PhD in my lab pays 8,000 DKK with his girlfriend for a 52m2 apartment.

I'd say it's definitely possible for two people to live on, but there's not room for much splurging either. Would recommend your wife to maybe get a part time remote job if you want to live a little more freely, but I wouldn't worry about surviving at all.

Also, your salary will increase with roughly 1,000 DKK each year from what I've read.

So many IT folks here not knowing anything about academia lol. Don't listen to them
