With all of the expenses you incur as a physician, rising interest rates are the last thing you need to worry about. Increasing your credit score now will help you save money in the long run. The more you can increase your credit score, which ranges from 300 to 850, the lower the interest rate youâ€™ll be charged on many loans, including mortgages. Bottom Line magazine offers the following advice on how to raise your credit score: Â· Keep an eye on ratio. Your credit card balance vs your credit limit can affect your score. Maintaining a balance under 30% of your credit card limit, will boost your score. Â· Own more than one credit card. Having multiple credit cards shows your lender that you are able to balance multiple debts, and make payments on time. Consolidating debt onto one credit card may raise your debt above the 30% threshold, which will only raise your interest rate. Â· Pay off all of your credit card balances. You can do this with an installment loan, while keeping your credit card accounts open. Paying your installments on time and reducing your credit card balance will also improve your overall credit score.
