Calculate Your Semester Grade
Calculate your weighted semester grade using your course grades and credit hours.
What Is a Semester Grade Calculator?
A Semester Grade Calculator helps you calculate your overall semester grade by combining the grades you earned in individual courses with their credit hours. Courses with more credit hours have a greater effect on your semester average than courses with fewer credit hours.
This calculator is useful for students who want to estimate their overall semester grade from multiple courses. If you need to find the average of several grades without credit-hour weighting, try our Average Grade Calculator.
How to Calculate Your Semester Grade
A semester grade can be calculated using a weighted average. Each course grade is multiplied by its credit hours, and the results are combined and divided by the total number of credit hours.
To calculate your semester grade:
- Enter the grade you received for each course.
- Enter the credit hours for each course.
- Add more courses using the Add Another Course button if needed.
- Click Calculate Semester Grade.
- The calculator will show your weighted semester grade.
Semester Grade Formula
The standard weighted semester grade formula is:
Semester Grade = [(Grade 1 × Credit Hours 1) + (Grade 2 × Credit Hours 2) + …] ÷ Total Credit Hours
This calculation gives more weight to courses that have more credit hours.
Example of a Semester Grade Calculation
Suppose you have three courses:
- Mathematics: 80% — 3 credit hours
- English: 90% — 3 credit hours
- Science: 70% — 3 credit hours
First, multiply each grade by its credit hours:
80 × 3 = 240
90 × 3 = 270
70 × 3 = 210
Add the weighted grades:
240 + 270 + 210 = 720
Then add the credit hours:
3 + 3 + 3 = 9 credit hours
Finally:
720 ÷ 9 = 80%
Your weighted semester grade is 80%.
Why Credit Hours Matter
Credit hours determine how much each course contributes to your overall semester grade. For example, a 4-credit course has a greater effect on your semester average than a 2-credit course when the grades are different.
This is why simply adding your course percentages and dividing by the number of courses may not give you the correct semester grade when courses have different credit hours.
When Should You Use a Semester Grade Calculator?
A semester grade calculator is useful when you want to estimate your overall performance before final grades are posted. You can use it to see how individual course grades contribute to your semester average and identify courses that have a larger impact because of their credit hours.
Can I Add More Courses?
Yes. You can use the Add Another Course button to add additional courses to the calculator. Enter the grade and credit hours for each course, and you can remove additional courses if they are no longer needed.
Frequently Asked Questions
How does a semester grade calculator work?
A semester grade calculator calculates a weighted average of your course grades using the credit hours for each course.
Does a course with more credit hours affect my grade more?
Yes. A course with more credit hours has a greater effect on your weighted semester grade.
Can I calculate my semester grade without credit hours?
You can calculate a simple average without credit hours, but that may not accurately represent your semester grade when your courses have different credit hours.
Can I add more than three courses?
Yes. Click Add Another Course to add additional courses to the calculator.
Does this calculator calculate GPA?
No. This calculator calculates a semester grade as a percentage. GPA is calculated using a grade-point system, which can vary between schools and universities.
What if I enter a grade above 100%?
Grades must be between 0% and 100%. If you enter a value outside this range, the calculator will ask you to correct it.
What if my courses have different credit hours?
The calculator accounts for different credit hours by giving each course an appropriate weight. A course with more credit hours contributes more to the overall semester grade.
What is the difference between a semester grade and GPA?
A semester grade is usually expressed as a percentage or letter grade based on your course performance. GPA uses grade points and may follow a different grading scale depending on your school or university.
