Am I missing any costs here?

Question

I'm trying to figure out if I have all the major (micro economics)-type costs in existence (whether it be running a business or owning a car)

Fixed costs include: Rent, Insurance, Interest, Advertising, Age depreciation

Variable costs include: Maintenance, Resources (including labor and materials), Use depreciation

Please let me know If I'm missing anything.

Answer 1

you forgot inventory (as opposed to simple raw materials)
There are taxes, of course...a big chunk of money
LOL, when it comes to costs, you are always missing something! No free lunch and all, you know

Answer 2

It is only my opinion here remember but it seems like advertising should be under variable as it optional while labor and material being your overhead fixed (not optional) age depreciation shouldn't be on the chart (repair & replacement maybe) Unless your reading this from a book then therefore you need to get the rest of your answer from the book.

Answer 3

Not sure advertising applies to owning a car for fixed costs.
Also as a business owner, my advertising is partly fixed and can be variable for special opportunities. It can vary year to year.
