A credit card could very well be the source of your credit-score sorrow. But it’s also your score’s best chance at recovery. You can’t remove negative records that are accurate from your credit reports. So the best you can hope for is to devalue them with a steady flow of positive information. And credit cards are perfect for the job because anyone can get them, they can be free to use, and they don’t force you to go into debt. Plus, they report information to the major credit bureaus on a monthly basis.
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.
