The grade calculator determines the weighted average grade and GPA associated with the given grades and weights.
How Does the Grade Calculator Work?
- First, choose the grade type. The tool accepts percentage, letter, and point grades.
- Now input the assignment or exam names, earned grades, and weights for each assignment.
- The tool also allows adding more rows by pressing the 'Add Row' button.
- You can also input the desired average grade to calculate the additional grade needed.
- After entering all the required values, click the 'Calculate' button.
- The tool returns the average grade result along with a step-by-step grade calculation.
- It also shows the additional grade needed to maintain an average score.
- For letter grades, the tool shows GPA results, and for points, it shows the total grade.
Weighted Grade Calculation
The basic formula to compute the weighted grade is:
| Weighted Grade = |
| ∑ (Grade × Weight) | | | ∑ (Weight) |
|
Or
| Weighted Grade = |
| g1×w1 + g2×w2 + ... | | | w1 + w2 + ... |
|
Example:
A student got the following grades:
| Category |
Grade (%) |
Weight (%) |
| Homework |
96 |
15 |
| Midterm |
73 |
35 |
| Final Exam |
89 |
50 |
Apply the above values to the formula:
| Weighted Grade = |
| (g1×w1) + (g2×w2) + ... | | | w1 + w2 + ... |
|
| = |
| (96×15) + (73×35) + (89×50) | | | 15 + 35 + 50 |
|
= 84.45%
