14. Pay your balance in full each month
To boost your credit score, pay off your entire balance every month. Pay all your credit card payments within the allotted time every month. Remember the due date of your card and pay at least some part of your credit bill before that date. Usually, the payment dates are fixed a few days after the commencement of a month. Still check your card statement to be double sure. A late payment can spoil your FICO score.
