AIf you have a good credit score, the chances of you being offered the loan at a low interest rate are quite high. Your credit score indicates your creditworthiness and your repayment ability. If you are looking to apply for a personal loan, it is advisable to maintain a credit score that is over 750. Individuals with a very low credit score may be denied a loan altogether, while those with a moderate credit score may be offered a personal loan, but at a high interest rate.
