Your credit score shows lenders how good (or bad) of a risk you are. If your credit score is high, it shows that you are a good risk and you probably pay all your bills on time. If your credit score is low, it indicates that you have trouble paying your bills. It could also indicate that you just don’t have much established credit yet.
Either way, the individuals who will be deciding whether to give you more credit or not will be looking at your credit score. They don’t give you a chance to explain why it is what it is, so the score has to speak for itself.
Your credit score can change rapidly, too, especially if you don’t have that much established credit yet, so pay attention to your debts and be sure to pay them on time.
