To qualify for Chapter 7 bankruptcy, you must have little disposable income. A means test is applied that compares your income to the median income in your state. If your average monthly income for the six-month period leading up to your bankruptcy filing is less than the median income for the same household size in your state, you automatically qualify.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
