To calculate your course grade: add up all your scores weighted by their importance. Example: Assignments 30% (scored 85), Midterm 30% (scored 78), Final 40% (scored 92). Grade = (85x0.30) + (78x0.30) + (92x0.40) = 25.5 + 23.4 + 36.8 = 85.7%. Your final grade is 85.7% — a B+.

✅ Trusted Tool
The 365tool.net Grade Calculator uses standard weighted average calculation. Free for students worldwide. Check your course syllabus for exact weight distribution and grading scale. No sign-up needed.
🤔 How Does This Work?
The Grade Calculator uses weighted average formula:
Final Grade = Σ(Score x Weight) / Σ(Weights)
Each grade is multiplied by its weight percentage
Results are summed and divided by total weight used
Letter grade is assigned based on standard scale
Shows minimum required final exam score to reach target grade
❓ Frequently Asked Questions
How do I calculate a weighted grade?▼
Multiply each score by its weight percentage, then add all the results. Example: Score 85 with weight 30% = 85 x 0.30 = 25.5 points. Score 90 with weight 70% = 90 x 0.70 = 63. Total = 25.5 + 63 = 88.5%. Make sure all weights add to 100%.
What grade do I need on my final exam?▼
Our calculator shows you the minimum final exam score needed to achieve your target course grade. This is based on: Required = (Target grade - current weighted average) / final exam weight. Very useful for exam planning!
What is the difference between weighted and unweighted grades?▼
Unweighted: simple average of all scores (equal importance). Weighted: each score multiplied by its importance percentage. Most university courses use weighted grades because exams count more than quizzes. Always check your syllabus for the exact weight of each component.
How are letter grades determined?▼
Common scale: A+ (97-100), A (93-96), A- (90-92), B+ (87-89), B (83-86), B- (80-82), C+ (77-79), C (73-76), C- (70-72), D (60-69), F (below 60). Some schools use different cutoffs — check your institution's grading scale.
What GPA does an 85% course grade give?▼
Varies by school. Common conversion: A (90-100) = 4.0, B+ (85-89) = 3.5, B (80-84) = 3.0, C+ (75-79) = 2.5, C (70-74) = 2.0. An 85% usually gives about 3.3-3.5 GPA depending on your school's scale.
