Weighted Grade Calculator
Use this calculator to estimate your course grade using your grades and category weights. It helps you check your current grade, overall course grade, and how homework, quizzes, tests, projects, participation, or final exams affect your final result.
Grade Categories
Add grades and weights to calculate your result.
How to Use This Calculator
Enter each assignment category from your course syllabus or gradebook.
For each row, add the category name, grade percentage, and weight percentage. Common categories include homework, quizzes, tests, assignments, projects, labs, participation, midterm, and final exam.
The calculator uses each category’s weight, so it gives a more accurate course grade than a simple average.
You can use it to estimate your weighted course grade, class grade, or overall grade when your course uses category weights.
Weighted Grade Formula
The basic formula is:
Weighted grade = Σ grade × weight ÷ Σ weight
In simple words, multiply each grade by its weight, add the results, then divide by the total weight.
Example:
| Category | Grade | Weight |
|---|---|---|
| Homework | 90% | 20% |
| Quizzes | 85% | 10% |
| Tests | 80% | 40% |
| Final Exam | 88% | 30% |
This helps you see the grade breakdown and how much each category contributes to your final result.
Example Weighted Grade Calculation
Suppose your homework grade is 90% with a 20% weight, quizzes are 85% with a 10% weight, tests are 80% with a 40% weight, and the final exam is 88% with a 30% weight.
The calculator uses those weights to estimate your final course grade.
This is helpful because a weighted average gives more importance to categories that count more in your syllabus.
Total Weight and Remaining Weight
Most classes use a total weight of 100%.
If your total weight is less than 100%, the calculator can show the remaining weight. This helps you see how much of the course is not included yet.
If the total is over 100%, check your grading policy again because one category may have the wrong weight.
A common mistake is entering the correct grades but using the wrong weights, which can make the result look confusing.
Current Grade vs Final Grade
A current grade calculator helps you check your grade using work already completed.
A final grade weight calculator helps when you want to understand how a final exam or remaining work may affect your result.
This page is mainly for calculating a current course grade or overall course grade from weighted categories. If you want to know what score you need on a final exam, use a final grade tool instead.
Weighted Grade vs Unweighted Grade
A weighted grade gives different importance to each category.
An unweighted grade treats every score equally.
For example, if exams are worth 50% and homework is worth 10%, the exam score has a much bigger effect on your result. That is why a weighted grade calculator gives a more realistic estimate than a basic average.
Common Grade Categories
Your grading system may include:
- homework
- quizzes
- tests
- assignments
- projects
- labs
- participation
- midterm exam
- final exam
Some courses may also include extra credit, coursework, or special assessment rules.
Always check your course requirements or grading scale before entering your numbers.
Understanding Your Result
The result may show your weighted score, percentage grade, letter grade, and category-level contribution.
Some schools use an A-F letter grade system, such as A+, A, A-, B+, B, B-, C+, C, C-, D, and F.
Others may use a 4.0 GPA scale, points system, or simple percentage system.
This tool gives a helpful estimate, but your official grade still depends on your teacher, school, college, or university policy.
When This Tool Helps
Use this calculator when you want to see how your grades and category weights affect your course result.
It can help you estimate your current class grade, understand which categories matter most, check your progress before the semester ends, and plan what score you may need next.

FAQs
What is a weighted grade?
This is a course grade where each category has a different value. For example, tests may count more than homework, depending on your grading policy.
How do I calculate my weighted grade?
Use this formula:
Weighted grade = Σ grade × weight ÷ Σ weight
You can also enter your grade percentages and category weights into the calculator to get the result faster.
What does weight mean in grades?
Weight means how much a category counts toward your final result. For example, a 40% exam category has more effect than a 10% homework category.
What if my weights do not add up to 100%?
If the weights are below 100%, you may still have remaining coursework or missing categories. If they are above 100%, check your syllabus or gradebook again.
Can I use this for high school or college?
Yes. This calculator can help with high school, college, and university classes if your course uses weighted categories.
Is this the same as a GPA calculator?
No. A GPA calculator usually converts course grades into a GPA value. This tool calculates a course percentage from weighted categories.
Can this show pass or fail?
It can help you estimate whether your result is near passing, but the exact pass or fail rule depends on your school, teacher, or course policy.
Can I use points instead of percentages?
Yes, but first convert your points into a percentage.
For example, if you earned 45 out of 50 points, your percentage is 90%. Then enter 90 as the grade percentage.
