You discover that every month that you make a loan payment on time, your credit score goes up 3 points. You want to raise your score from 640 to 700. How many months will it take you?
So you still have 60 points to go up. Every month is 3 more points. Divide 60 by 3 which will give you the number of months left before you reach your goal. 60/3= 20 months or 1 year and 8 months.
