Average grade:
Keeping track of grades can be a challenge for students juggling multiple assignments, tests, and projects. Whether you’re aiming to maintain a high GPA, determine how well you’re performing in a course, or forecast your final grade, having a reliable Grade Calculator is essential.
This article introduces a user-friendly, web-based Grade Calculator that helps students easily compute their weighted average grades based on input scores and their respective weights. With a clean interface and a precise calculation engine, this tool simplifies academic planning and grade tracking.
What Is a Grade Calculator?
A Grade Calculator is a tool designed to compute the average grade based on individual grades and their corresponding weight. Each assignment, quiz, or exam may not contribute equally to your final grade. Therefore, the calculator uses a weighted average formula to give you an accurate result.
Whether you’re a high school student, a college learner, or even an instructor wanting to check grading, this tool comes in handy by offering quick insights into performance.
How to Use the Grade Calculator
Using the calculator is very straightforward:
- Enter Assignment Name (optional): You can provide the title of your assignment, test, or project. This helps in organizing the data clearly but is not required for the calculation.
- Enter Grade (%): This is the percentage score you received for each task. For example, if you scored 90 out of 100, enter 90.
- Enter Weight: Each task may carry a different weight. A final exam might be 40% of the total grade, while a quiz might only be 10%.
- Add More Rows: Click on the “Add Row” button to enter more assignments.
- Calculate Grade: Once all entries are filled, click “Calculate” to get your weighted average grade and the corresponding letter grade.
- Clear All: Use the “Clear” button to reset the calculator.
Formula Used in the Calculator
The grade calculator works on a weighted average formula. Here’s the simple version of the formula:
Weighted Average Grade = (Grade1 × Weight1 + Grade2 × Weight2 + … + GradeN × WeightN) / (Weight1 + Weight2 + … + WeightN)
Example Calculation:
Let’s assume the following data:
- Homework: Grade = 85%, Weight = 20
- Midterm: Grade = 90%, Weight = 30
- Project: Grade = 75%, Weight = 25
- Final Exam: Grade = 95%, Weight = 25
Step-by-step Calculation:
Weighted Sum = (85 × 20) + (90 × 30) + (75 × 25) + (95 × 25)
Weighted Sum = 1700 + 2700 + 1875 + 2375 = 8650
Total Weight = 20 + 30 + 25 + 25 = 100
Average Grade = 8650 / 100 = 86.5
Result:
- Average Grade: 86.5%
- Letter Grade: B
Letter Grade Mapping
Once the average is calculated, the tool assigns a letter grade based on standard academic grading scales:
- A: 90–100
- B: 80–89
- C: 70–79
- D: 60–69
- F: Below 60
The grade is also color-coded for visual understanding:
- Green for A
- Blue for B
- Orange for C
- Red for D
- Black for F
