I actually don't, those are the only two expenses my family has. Come to think of it those are the only two expenses I've ever had. I guess if we lived in the countryside we'd need a car, so, three expense categories total.
But alright, gather all of these other miscellaneous expenses up and take out another $10k per year to cover them. You still have $30,000 left if you're paying $2k a month on rent.
You don't pay for utilities, or public transport? Your family has never had to pay for clothes, or school books, or healthcare expenses (I know those aren't completely socialized in Finland)?
I agree an 18-year-old earning $100k is doing great even in the most expensive parts of California, but you don't sound like you've ever actually had to think through a household budget.
I would think that there would still be other expenses in some form:
- Utilities on shared apartment with roommates (unless you are lumping this into rent)
- Doctors co-pays (or the money to spend out of pocket until you meet your deductible, depending on your health insurance)
If you have a car,
- car insurance
- gas
- car maintenance costs such as 6 month services
