Your credit score partly depends on your credit utilization – the amount of debt you carry as compared to the total amount of debt available to you. If all of your credit cards are maxed out, opening a new one increases your available debt and causes your utilization ratio to go down, and that could help your score. But your score will take a ding any time you carry a high balance on any one card. So if you transfer multiple balances to a single card and get close to (or reach) your credit limit, your score will suffer even if your other cards are paid off.
Once you've paid down the balance of your credit cards, keep your spending on these accounts down. You should aim for a balance that is less than 30% of your credit limit on the card. Don't voluntarily lower credit limits; this can hurt rather than help your FICO® Score. If your credit report doesn't reflect your actual credit limit, make sure your credit card company updates this information with the credit bureaus. In addition to limiting your spending on the accounts you already have, be cautious when any new accounts and don't cancel any old accounts since these help your credit score by demonstrating a longer credit history.
You cannot use your existing credit cards while you’re on a debt management plan, nor can you open new accounts. McClary also said that if you do manage to open new credit card accounts during your debt management plan, existing creditors who find out may stop participating in your debt management plan and reset your account to its original terms and interest rate.
If you have one of those letters we mentioned earlier that details your credit problems, you have some idea of what’s holding you back. Even though it may seem complex, as we mentioned, your credit score is based on five core factors: payment history, credit utilization, the age of credit accounts, mix of credit accounts and history of applying for credit. They’re not equally weighted, and this information will most likely vary between credit bureaus.
Step 2: Tell the creditor or other information provider, in writing, that you dispute an item. Include copies (NOT originals) of documents that support your position. Many providers specify an address for disputes. If the provider reports the item to a consumer reporting company, it must include a notice of your dispute. And if the information is found to be inaccurate, the provider may not report it again.
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.
