If you've already used up your free credit reports for this year, you can order your credit reports directly from the credit bureaus for a fee. The bureaus all offer a three-in-one credit report that lists all three of your credit reports side-by-side. The three-in-one credit report costs more than a single credit report, but less than the combined price of purchasing your three individual credit reports.
Credit scoring models usually take into account how much you owe compared to how much credit you have available, called your credit utilization rate or your balance-to-limit ratio. Basically it's the sum of all of your revolving debt (such as your credit card balances) divided by the total credit that is available to you (or the total of all your credit limits).
