Money
The cost of living in Finland is high, even by European standards (although prices may differ a lot between cities).
On average, about one-fifth of Finns’ net income goes to housing. Since Finland is a cold country, heating is usually the largest single expense item in detached houses. It can account for almost one-half of the housing costs. Other costs in a detached house include property tax, electricity, water, waste collection and any repairs.
The prices of food and non-alcoholic drinks in Finland are 20% higher than the European average. The prices of alcoholic drinks are 80% higher than average.
Anyway, if you have a family with children and you are permanently residing in Finland, you can apply to the "Kela" card from the Social Insurance Institution of Finland for many benefits.
Also as a student in Finland, you are most often entitled to discounts in public transports, recreational facilities, meals etc.
