Calculate your college course grade based on assignments, exams, and their respective weights. Get insights on your academic performance and tips for improvement.

Check your course syllabus for the specific grading policy used in your class.
College grading systems can vary between institutions, but most follow a standard percentage-to-letter grade conversion. Understanding how your grades are calculated is essential for academic success and planning your study efforts effectively.
Most college courses use a weighted grading system, where different components contribute different percentages to your final grade. Understanding how weighted grades work is crucial for accurately calculating your course standing.
Final Grade = (Item1 Score × Item1 Weight) + (Item2 Score × Item2 Weight) + ...
| Assignment | Your Score | Weight | Weighted Score |
|---|---|---|---|
| Midterm Exam | 85% | 30% | 25.5 points |
| Final Exam | 78% | 40% | 31.2 points |
| Assignments | 92% | 20% | 18.4 points |
| Participation | 95% | 10% | 9.5 points |
| Final Grade | 84.6% | ||
In this example, the final grade of 84.6% is calculated by adding all the weighted scores: 25.5 + 31.2 + 18.4 + 9.5 = 84.6
Different colleges and universities may use slightly different grading scales. Here are the most common ones:
| Letter Grade | Percentage | GPA Value |
|---|---|---|
| A | 90-100% | 4.0 |
| B | 80-89% | 3.0 |
| C | 70-79% | 2.0 |
| D | 60-69% | 1.0 |
| F | 0-59% | 0.0 |
| Letter Grade | Percentage | GPA Value |
|---|---|---|
| A+ | 97-100% | 4.0 |
| A | 93-96% | 4.0 |
| A- | 90-92% | 3.7 |
| B+ | 87-89% | 3.3 |
| B | 83-86% | 3.0 |
| B- | 80-82% | 2.7 |
Note: Grading scales may vary by institution. Always check your course syllabus or academic handbook for the specific scale used at your school.
Weighted grades are calculated by multiplying each assignment's percentage score by its weight (as a decimal), then adding all these weighted scores together. For example, if you scored 85% on an exam worth 30% of your grade, that contributes 25.5 points (85 × 0.3) to your final grade.
If your weights don't add up to 100%, the calculator normalizes them by dividing each weighted score by the total weight percentage. This ensures your final grade is properly scaled. However, it's best to make sure your weights sum to 100% for the most accurate calculation, as this matches how most instructors calculate final grades.
This calculator supports three common grading systems:
Select your preferred system from the dropdown menu to see grades displayed in that format.
This calculator is designed for individual course grades, not your overall GPA. For GPA calculations, you would need to use a dedicated GPA calculator that takes into account credit hours and grades from multiple courses.
Check out our College GPA Calculator for that purpose.
This calculator uses standard weighted average formulas that match how most college courses calculate final grades. However, some instructors may use different methods, such as dropping the lowest score or using a curve.
Always refer to your course syllabus for the exact grading policy, and consider this calculator as a helpful estimate rather than a guarantee.
For assignments you haven't completed yet, you can either:
The most accurate approach is to only include assignments that have been graded, then use the What-If feature to plan for future assignments.
