Beyond that is creditor information, which makes up most of your reports. This includes different accounts you have (loans, credit cards, etc.), their status (open/closed, in collections), balances, credit limits and payment details. This may also include dates of missed payments or late payments, or when the accounts were sent to collections. From these details, your credit scores will be formed.
That takes care of your existing credit accounts. To help establish positive credit history, you might contemplate opening new credit accounts in various categories. Showing that you can handle fixed payments as well as credit cards is a plus in the long term. An installment loan for furniture, an auto or a personal loan will round out your credit profile. You might also consider a secured credit card (make sure the issuer reports to the major credit bureaus) if you do not qualify for other types of new credit. Lastly, apply for credit only if you need it and if you can afford new payments. Credit applications generate inquiries on your credit report, which could ding your score in the short term.
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.
