The earlier you find out about a credit report or identity theft issue, the easier it is to solve. To ensure that you find out about issues in the future, consider signing up for a credit monitoring service. Some companies, like CreditKarma, offer free credit monitoring. Other companies offer daily three-bureau monitoring and resolution services. You can learn more about these options here.
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.
