Tracking Spending

• When you pay with cash, it's easy to count how much you have left to spend. With a credit card, you may have a much harder time keeping track of how much you've spent because you still have that same piece of plastic.
  
  

Fees

• Credit cards are notorious for imposing fees on their users, including annual fees, late-payment fees and over-the-limit fees.
  
  

Being Stolen

• Credit cards can be stolen. Even if you are able to prevent the thief from racking up charges, it still takes time to call the credit card company and have your account frozen.
  
  

Interest Rates

• Credit cards are unsecured loans, which means you have not used anything as collateral to back the loan. Therefore, the interest rate charged on your balance is very high.
  
  

Minimum Payments

• The minimum payments on credit cards are relatively small, and often cover little more than the cost of the interest on the account. Though you may think you are paying down your balance because you are always making the required payment, it will generally take a very long time to actually pay the balance off.
