Purdue Grade Calculator

When it comes to academics, keeping track of grades is one of the most important things students can do to stay motivated and plan effectively. For Purdue University students, course grades often consist of multiple components such as assignments, quizzes, midterms, and final exams. Each of these carries a different weight, and figuring out your final grade can sometimes feel overwhelming.

That’s where the Purdue Course Grade Calculator comes in. This tool allows students to input their assignment scores and weights, instantly generating their overall grade and corresponding letter grade. Whether you’re aiming to maintain a scholarship, qualify for honors, or simply stay on track, this calculator helps you stay informed.

2. Input Your Scores – Enter the score you achieved for each assignment or test (between 0–100%).
3. Add the Weight – Input the percentage weight of each assignment (e.g., if your final exam is worth 50% of the grade, type 50).
4. Add/Remove Rows – Use the “+” button to add more assignments or the “–” button to remove any unnecessary rows.
5. Click Calculate – Hit the Calculate button, and the tool will compute your final weighted grade.

Practical Example of Using the Calculator

Let’s say you’re taking a Purdue course with the following grading structure:

• Homework (10%) – Score: 100%
• Quiz (10%) – Score: 90%
• Midterm Exam (30%) – Score: 85%
• Final Exam (50%) – Score: 82%

When you input these values into the calculator:

• Total Weighted Percentage = (100×10) + (90×10) + (85×30) + (82×50) = 85.9%
• Total Weight = 100%
• Final Grade = 85.9%
• Letter Grade = B

This means you’ll end the course with a solid B, giving you a clear understanding of your standing.
