Grade Average Calculator
A grade average calculator helps students determine the average grade across multiple assignments, quizzes, tests, or exams. Instead of manually performing grading calculations, this calculator quickly computes the average using numerical values or weighted grades.

Simple average · Weighted average — live results
Many schools and colleges evaluate a course grade by combining several scores such as homework, exams, and the final exam. Using a calculator simplifies this grade calculation process and helps students track their current grade and overall course performance.
If you want to calculate grades from points earned or percentage scores first, you can also use the grade calculator before determining the average grade.The calculator lets students enter several grades or scores from assignments and exams. It then computes the average grade using either weighted or unweighted grading methods. This makes it easier to determine how each score affects the final grade in a class.
Key Features
This grade average calculator provides several helpful features:
• Calculate the average grade from multiple scores
• Supports weighted average grade calculations
• Works for school or college grading systems
• Converts percentage grades into letter grades
• Helps determine the current grade and overall course grade
• Simple interface designed for quick grade calculations
Because the calculator performs the math automatically, it prevents mistakes in manual grade calculations.
How to Use the Grade Average Calculator
Follow these steps to calculate grades:
- Enter the scores or grades for each assignment, quiz, or exam.
- Enter the weight percentage if the course uses weighted grading categories.
- Click calculate to compute the average grade.
- The calculator shows the average percentage and corresponding letter grade.
This method helps students track their academic progress throughout a semester.
What Is a Grade Average Calculator
A grade average calculator is an academic tool used to determine the average grade for a class or course. Teachers typically assign several graded activities during a quarter or semester, including assignments, quizzes, exams, and the final exam.
Each score contributes to the overall grade. By calculating the average using multiple grades, students can determine their current overall grade in the course.
Some courses use unweighted grading, where each score contributes equally. Other courses use weighted grading, where certain categories such as exams or final exams have greater importance.
How the Calculator Works
The calculator collects several grade values and determines the average using a mathematical formula.
If the course uses unweighted grading, the calculator simply adds all scores and divides by the number of values.
If the course uses weighted averages, the calculator multiplies each score by its weight percentage and divides the total by the sum of the weights.
This process ensures accurate grade calculations based on weighted averages.
Formula Used
Unweighted Average Formula
Average Grade =
Sum of all grades ÷ Number of grades
Weighted Average Formula
Weighted Average Grade =
(S1 × W1 + S2 × W2 + S3 × W3) ÷ Sum of the weights
Where:
S = score
W = weight percentage
The calculator multiplies each score by its weight, then divides by the sum of the weights to determine the weighted average grade.
Example Calculation
Example:
Assignment = 85
Quiz = 90
Exam = 80
Calculation:
(85 + 90 + 80) ÷ 3 = 85
Result:
The average grade is 85 percent, which corresponds to a B letter grade in most grading systems.
Letter Grade Scale
Most grading systems convert percentage grades into letter grades using a standard grading scale.
| Percentage | Letter Grade |
|---|---|
| 97–100 | A+ |
| 93–96 | A |
| 90–92 | A- |
| 87–89 | B+ |
| 83–86 | B |
| 80–82 | B- |
| 77–79 | C+ |
| 73–76 | C |
| 70–72 | C- |
| 67–69 | D+ |
| 63–66 | D |
| 60–62 | D- |
| Below 60 | F |
The grading scale may vary by school or university, but most systems follow a similar structure.
Benefits of Using This Calculator
