How to Calculate a Grade Percentage

Converting points to a percentage is simple. Divide the points you earned by the total points possible, then multiply by 100. The result is your percentage grade.

Grade % = (Points Earned ÷ Points Possible) × 100

Example 1: 45 out of 50 points
Grade % = (45 ÷ 50) × 100 = 90% → A−

Example 2: 42 out of 50 points
Grade % = (42 ÷ 50) × 100 = 84% → B

Example 3: 32 out of 35 points
Grade % = (32 ÷ 35) × 100 = 91.43% → A−

Example 4: 17 out of 20 points
Grade % = (17 ÷ 20) × 100 = 85% → B

Enter points earned. This is how many points you received on the assignment. For example, if your score is 45/50, enter 45.
Enter points possible. This is the maximum number of points available. In a score of 45/50, the possible points are 50.
Read your result. Your percentage, letter grade, GPA equivalent, points lost, and points needed for the next grade appear instantly.
