Example Input: [header] How to create a transition budget [title] Record your income.

For example, if you earn $70 a week for a month, you should record an income of $57. (B) Find out the specific amount that you make in a month or year, then translate that into how much money you have at your disposal each time the bulk of your expenses are made (typically every month).

(C) This means that you should begin documenting expenses that are money you've already made and converting them into cash.
