A low credit score will hurt you when you try to get any kind of credit. Although you may not be refused new credit, you may not get the best interest rates. You also will not be given large amounts of credit or longer repayment periods to pay back the debt.
Fair or even bad credit scores can be improved. It will take time, but any effort you put toward improving your credit score will be worth it if you ever plan to borrow money or get a credit card with a low-interest rate.
