Accomodation can be a lot more expensive in Utrecht if you 're not lucky. I'm paying 415 per month. Anyway, 18.000 are plenty, don't worry. And if its a scholarship, then you won't have to pay any taxes. I am thinking of starting a PhD myself here. Can someone tell me what would be the taxes in 30.000 euros per year? Or a rough percentage maybe? I really have no idea. Thanks
