Make a budget. If you have old electric, phone, rent, car bills for the last three months, get them out and write down how much you spent. Utilities are the hardest because the cost of heating or cooling swings drastically with the seasons. Most utilities will allow you to pay the same amount and calculate that amount for you if you have lived in the same place for 12 months or longer.. . If you do not have these bills, save them for the next three months. Also write down other expenditures like the mornings you stop for Starbucks, eating out, drinks with friends, savings, gas, and other regular expenses.. . Don't think of a budget as limiting your spending, but as a tool to help prioritize your spending.
