Different way of looking at it. Budgets are more like setting enterprise or department-wide financial targets.

If you want something more comparable between a company's spending and a family's budget (where they account for every dollar), look at the Statement of Cash Flow. Money comes in from operations (work), some comes in through financing (loans), some goes out the door when you buy new assets to make more money later on (car) then whatever is left over can get put into retained earnings (savings).
