If you are a careful money manager who fell into debt because of unusual circumstances (medical or veterinary bill, loss of employment or some other emergency) and NOT because you spent more on your credit cards than you could afford to pay off each month, then leave the accounts open. Doing so will help your credit score, because the amount of revolving debt you have is a significant factor in your credit score. Just be sure to put the cards away. Don’t use them while you pay down your debt consolidation loan.
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.
