How to Use the Grade Calculator
Follow these steps to calculate your weighted course grade from any syllabus:
Identify Assessment Categories
Check your syllabus for all graded components — homework, quizzes, tests, midterm, final exam, participation, projects, labs, etc.
Enter Weight Percentages
Input the weight for each category exactly as listed in your syllabus. Weights should total 100%, but the calculator normalizes automatically if they don't.
Input Your Scores
Enter your current average or earned percentage for each completed category. For in-progress categories, enter your running average.
Add More Categories
Click "Add Category" to include additional assessment types. Our calculator supports unlimited categories for complex course structures.
Calculate & Analyze
Click "Calculate Grade" to see your weighted overall grade. Adjust scores to run what-if scenarios for upcoming assignments.
Weighted Grade Formula
Overall Grade = Σ (Category Score × Category Weight) ÷ Σ (Category Weights)
Each category contributes proportionally based on its syllabus weight
Example: Psychology 101
- • Homework (20%): 88%
- • Quizzes (15%): 92%
- • Midterm (25%): 78%
- • Research Paper (15%): 95%
- • Final Exam (25%): 85%
(88×0.20) + (92×0.15) + (78×0.25) + (95×0.15) + (85×0.25)
= 17.6 + 13.8 + 19.5 + 14.25 + 21.25 = 86.4% (B+)
Standard Grading Scale
This is the most common grading scale used at US colleges and high schools. Your school may vary — check your syllabus. For GPA conversion, use our Percentage to GPA Calculator.

|---|---|---|---|
| A+ | 97–100% | 4.0 | Exceptional |
| A | 93–96% | 4.0 | Excellent |
| A− | 90–92% | 3.7 | Very Good |
| B+ | 87–89% | 3.3 | Good |
| B | 83–86% | 3.0 | Above Average |
| B− | 80–82% | 2.7 | Slightly Above Average |
| C+ | 77–79% | 2.3 | Average |
| C | 73–76% | 2.0 | Satisfactory |
| C− | 70–72% | 1.7 | Below Average |
| D+ | 67–69% | 1.3 | Poor |
| D | 60–66% | 1.0 | Barely Passing |
| F | Below 60% | 0.0 | Failing |
How to Calculate Final Grade
Whether you want to know your current standing or figure out what you need on the final exam, here are the two essential formulas:
Calculate Current Grade
Add up weighted scores for all completed categories:
Calculate Required Final Score
Find what you need on the final exam:
Worked Example: What Do I Need on the Final?
| Scenario | Current | Goal | Final Weight | Need on Final |
|---|---|---|---|---|
| Keep my A | 92% | 90% | 30% | 85.3% |
| Raise to B+ | 82% | 87% | 25% | 102% ❌ |
| Pass the class | 68% | 60% | 40% | 48.0% |
❌ means the required score is over 100% — mathematically impossible without extra credit. For instant results, use our Final Grade Calculator.
Tips for Improving Your Grade
Focus on high-weight categories
A 40%-weight exam matters more than 10%-weight homework. Allocate study time proportionally.
Never skip easy points
Participation, attendance, and homework are usually easy A's that pad your grade significantly.
Run what-if scenarios
Use this calculator to see how different scores on upcoming work would change your overall grade.
