There are many things you should consider when shopping for a credit line for an 18-year old. You will first need to ensure that the interest rate you are paying is fair. Many credit cards have high interest rates, often expressed as annual percentage rates (APRs). Consider a variable APR credit card if you are concerned about excessive interest rates. You should also remember that your credit report will include your outstanding balances. High balances can affect your credit score. High credit balances can also affect your credit utilization ratio. This is the ratio of the amount of credit available to you and the total debt that you owe. Credit scores can be seriously affected if you have a credit score of 30 or more.
