How to Calculate an Accumulative Grade Point Average
- 1). Determine the period for which you want to calculate your cumulative GPA. For example, when applying to college, you will likely want to include all of the courses you took for high school credit.
- 2). Convert each grade to a point value. Most GPAs use a four-point grade scale, meaning an A converts to 4, B to 3, C to 2, D to 1 and F to 0.
- 3). Add any bonuses for harder classes if your school weights the GPA. For example, a school may add 1 point for honors classes, so an A in an honors class would be 5 points.
- 4). Multiply the adjusted point values by the number of credits each class is worth. For example, if your honors A class is worth two credits, you would multiply 5 by 2 to get 10.
- 5). Add the results from Step 4 to find the total number of grade points earned.
- 6). Divide the total grade points you have earned by the credits you have earned to find your cumulative GPA. For example, if you had earned 99 grade points over 30 credits, you would divide 99 by 30 to find your cumulative GPA to be 3.3.
