Grade Calculator
Use our free Grade Calculator to calculate your final grades, course averages, and weighted scores. Perfect for students to track academic performance and plan study goals.
How Does Grade Calculation Work?
Most courses use a weighted grading system where different categories (assignments, exams, projects, participation) contribute different percentages to your final grade. For example, exams might be worth 40%, homework 30%, and projects 30%.
This calculator computes your weighted grade (using the weight you assign to each item), unweighted average (total points earned ÷ total points possible), and converts your percentage to a standard letter grade and GPA.
How to Use
- Enter each assignment name, score, and total points
- Set the weight % for each category

Standard Letter Grade Scale
| Letter | A+ | A | A- | B+ | B | B- | C+ | C | C- | D+ | D | F |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| % | 97–100 | 93–96 | 90–92 | 87–89 | 83–86 | 80–82 | 77–79 | 73–76 | 70–72 | 67–69 | 65–66 | <65 |
| GPA | 4.0 | 4.0 | 3.7 | 3.3 | 3.0 | 2.7 | 2.3 | 2.0 | 1.7 | 1.3 | 1.0 | 0.0 |
Grading scales may vary by institution. Check your school's specific grading policy.
Weighted vs Unweighted Grades
Weighted Grade
Each category has a different weight. If exams are 50% and homework is 50%, scoring 80% on exams and 100% on homework gives: (80×0.5) + (100×0.5) = 90%.
Unweighted Grade
All points treated equally. If you earned 180 out of 200 total points, your unweighted grade is 180/200 = 90%.
FAQ – Grade Calculator
What is a Grade Calculator?
A Grade Calculator helps you determine your overall course grade based on individual assignment, quiz, project, and exam scores. It calculates your final grade by applying the correct weight to each category and converts it to a letter grade.
How does weighted grading work?
In a weighted grading system, each category contributes a specific percentage to your final grade. The calculator multiplies each score by its weight, sums them, and divides by total weight to get your overall percentage.
What's the difference between weighted and unweighted grades?
Weighted grades account for the importance of each category (e.g., exams worth more than homework). Unweighted grades simply divide total points earned by total points possible, treating all assignments equally.
How do I use the weight percentage?
Enter the weight as a percentage reflecting how much each category counts toward your final grade. If your midterm is worth 30%, enter 30. If all assignments are equal, leave the default value of 100 for each.
Can I add multiple assignments?
Yes! Click "Add Row" to add as many rows as you need — homework, quizzes, exams, projects, participation, etc. Each row can have its own name, score, and weight.
What letter grade do I need to pass?
Most schools require a minimum of C (73%) or D (65%) to pass. Some programs require a C or higher in major courses. Check your institution's specific requirements.
How is the letter grade determined?
The calculator uses the standard US grading scale: A+ (97–100%), A (93–96%), A- (90–92%), B+ (87–89%), B (83–86%), and so on down to F (below 65%).
Can I use this for college and high school?
Yes. The calculator works for any level — middle school, high school, college, or university. Just enter the correct weights and scores for your specific course structure.
What if my weights don't add up to 100%?
The calculator normalizes the weights automatically. If your weights total 80% (because some assignments aren't graded yet), it calculates your grade based on the completed portion only.
What are the quick templates?
"Standard Course" pre-fills typical categories (homework, quizzes, midterm, final). "Exam Heavy" weights exams at 70%. "Project Based" emphasizes projects and presentations. Customize the values after loading.
