Establish a Budget
First, you need to assess your income. How much do you bring in every year, with any salary, bonuses, dividends, interest, support, or other means of income included?
You should expect to spend about 60% of your budget on the top three budget items for most families, which includes housing, transportation, and food. Avoid going too far over this number, because you'll also need money for emergency funds, your retirement plan, entertainment, credit card payments, insurance, and all of your other monthly expenses.
