How to Calculate My Class Grade


Why should one calculate Class grades?

Class grades are important to be calculated so that you know where do you stand in the particular semester or the course. Once you know your class grade, you can further calculate your overall grade by using the grade calculator.

Your GPA can take you a long way in determining the kind of college you want to get in. Not only you can keep a track of your progress and also find out the level of effort you need to put in to be on the required path.

Be it any phase or sphere of life, half the battle is won when you know what is your goal and the other half is won when you find out how to achieve it. A student really battles his way to get the desired overall grade that is not just dependent on his or her final score but also his/her class grades over the course.

Once you know how much you need to attain in order to get the desired grade, no one can stop you from achieving it. In case you are wondering how to get that grade, here is a super simplified yet effective way to calculate your class grade using our class grade calculator.

You can use the calculator to tabulate the course grade right before the finals so that you have a target in front of you.


Using the class grade calculator is no rocket science and you can easily compute what you are looking for. All you have to do is enter your current percentage on an assignment, assessment or internal exam and the value or weight that it carries towards your final grade.

Whenever you wish to update your results and add the score for new assignment or test, click on “Add new Assignment’. As soon as you input all assignments in the required field, your result will be updated.


Use our calculator to find out the grade of a course based on weighted averages. This calculator accepts both numerical as well as letter grades. It also can calculate the grade needed for the remaining assignments in order to get the desired grade for an ongoing course.


Before we compute the class grades, it is important to comprehend the number of assignments or assessments used to comprise your grade in a particular course. Once you know how many tests, internal exams are conducted and how much percentage they are worth, it becomes a cakewalk to compute your desired grades.

You can easily calculate the grade by determining if you are on a point system or the weighted one. Once you figure it out, you can go ahead with determining the total number of points earned on the completed assignments. The total of the points earned has to be taken out. The total can help you determine your percentage.


You can calculate your percentage in each category and once it is done, add the numbers to deduce your class percentage. You can convert your percentage to a letter grade and find your letter grade as well. The very simple calculation process can help you a great deal.

Weighted grade calculation

The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g):

Weighted grade = w1×g1+ w2×g2+ w3×g3+…



Math course with a grade of 80 and a weight of 30%.

Biology course with a grade of 90 and a weight of 50%.

History course with a grade of 72 and a weight of 20%.

The weighted average grade is calculated by:

Weighted grade =


w1×g1+ w2×g2+ w3×g3

= 30%×80+ 50%×90+ 20%×72 = 83.4

When the weights are not in percent (hours or points…), you should also divided by the sum of the weights:

Weighted grade = (w1×g1+ w2×g2+ w3×g3+…) / (w1+w2+w3+…)


3 points Math course with grade of 80.


5 points Biology course with grade of 90.

2 points History course with grade of 72.

The weighted average grade is calculated by:

Weighted grade =

= (w1×g1+ w2×g2+ w3×g3) / (w1+w2+w3)


= (3×80+ 5×90+ 2×72) / (3+5+2) = 83.4

Conversion of Percentage to a letter grade

Letter grades come handy to teachers where they can generalize a student’s performance. It is also very useful when there is no time to go in a more comprehensive evaluation by giving a subjective feedback to the students. Again, depending from school to school, the evaluation system varies.

Letter grades can be quickly quantified and solves the purpose where only “right” or “wrong” answers are to be evaluated. If your teacher uses the letter grade system, then that too can be done bysimply convertingthe percentages you have calculated to a letter grade.

While letter grades are pretty common in most of the education systems where grades are give, there are other ways of grading as well. Some of you might want to know the percentage derived out of the letter grade in a particular assignment.

Also, the letter grading scale can vary from school to school and your class grade can is dependent on the percentage grades widely. However, this is the most commonly used scale in the United States:

  • A = 93 – 100%
  • A- = 90 – 92%
  • B+ = 87 – 89%
  • B = 83 – 86%
  • B- = 80 – 82%
  • C+ = 77 – 79%
  • C = 73 – 76%
  • C- = 70 – 72%
  • D+ = 67 – 69%
  • D = 63 – 66%
  • D- = 60 – 62%
  • F = 0 – 59%

Why is Class Grade Important?

Class grades are important as they can determine your performance and also the level of hard work you need to put in to achieve the desired grade.

You can gauge the amount of effort you need to put in for your finals and accordingly work on your temperament. Class grades are crucial and can have some impact on your final grades as well.
