Thanks for the insight Omar. I moved to Hungary, so not really a third world country. I've only been living here for ~3 months so my estimate might be of by a bit.

1) I don't really need a car since public transport here is ok. However I do own one. I cut my car costs to a minimum by changing from a sports car to a 10 year old Ford Focus.

2) I have an accountant that costs about 300 euros per month right now, is one of the bigger costs that I have right now. Am gonna try do take on most marketing tasks myself.

3) I never accounted for inflation so far. This might be something that I have to look into a bit more.
