Those on a fixed salary can determine how many times they get paid per month and multiply that number by their net paycheck amount to determine their total monthly income. For example, if you get a bi-weekly paycheck, then you receive two paychecks per month. If your net paycheck after taxes is $1,250, then your total monthly income would be $2,500 ($1,250 x 2 = $2,500). If you are paid bi-weekly, this means you receive 26 paychecks per year, or two extra, because two months of the year have will have three paydays. Be aware which months include this additional payday. If you are paid semi-monthly, you will receive two paychecks per month, regardless of the length of the month, resulting in 24 paychecks per year. If you get paid hourly or your income is irregular for any reason, then look at the last six to 12 months of paychecks. Figure out the average you earn per month. For example, suppose over the past six months you earned $2,500, $3,000, $2,000. $1,800, $3,200, and $2,700. Add these amounts together to get the total ($15,200). Divide the total by 6 to get the average monthly salary ($15,200 / 6 = $2,533 per month).

If you are not sure how much you spend each month on some of these items, then track your expenses for a few weeks.

You may not be able to make adjustments on some of your line items. Some expenses, such as your rent or mortgage, may be fixed and cannot change in the short-term. However, chances are that you will be able to find many other areas where you can reduce your spending. For example, many people begin by looking at how much they’re spending on food and plan to eat out fewer times per month. Plan to pay down debt. If you can reduce your expenses for groceries, cable, cell phones and clothing enough, you can divert some of those funds towards paying down your credit card debts. Plan to save as much as possible. Also, you should definitely plan to save up a rainy day fund of at least a few thousand dollars. Having this money put aside will allow you to pay for unexpected expenses as they come up without having to use your credit cards and incur more debt.

Using these assumptions, the average cost of take-out or restaurant meal for a family of four is $52 ($13 x 4 = $52), and the average cost of meal cooked at home for a family of four is $16 ($4 x 4 = $16). So, the weekly savings from cooking two meals at home would $72 ($52 - $16 = $36; $36 x 2 = $72). By cooking at home two times more per week, a family of four could save as much as $288 per month on food ($72 x 4 weeks = $288).
