Weighted Grade Calculator
Calculate your weighted grade and find out what you need on your remaining work.
What Is a Weighted Grade Calculator?
A Weighted Grade Calculator helps you calculate your course grade when different assignments or categories are worth different percentages of your final grade. Instead of treating every grade equally, a weighted calculation gives more importance to categories with larger weights.
For example, your homework may be worth 20% of your course grade, quizzes may be worth 30%, and exams may be worth 50%. If you have different percentages for each category, a weighted grade calculator can quickly determine your current grade.
Our calculator also shows your completed course weight and remaining weight. If you enter a target grade, it can estimate the percentage you need on your remaining work to reach that target.
How to Use the Weighted Grade Calculator
You can calculate your weighted grade in a few simple steps:
- Enter the name of your grade category, such as Homework, Quizzes, Projects, or Exams.
- Enter your current grade percentage for that category.
- Enter the percentage weight of that category.
- Click + Add Another Grade to add more categories.
- Click Calculate Weighted Grade to calculate your current weighted grade.
- Enter a Target Grade if you want to know what grade you need on your remaining coursework.
The calculator displays your current weighted grade, completed course weight, remaining course weight, and the required grade for your target when enough course weight remains.
How to Calculate a Weighted Grade
To calculate a weighted grade, multiply each grade by its decimal weight. Then add the weighted values together. If you have completed only part of the course, divide the weighted points by the completed weight to find your current weighted grade.
For example, suppose you have a homework grade of 90% worth 20% and a quiz grade of 80% worth 30%.
Homework: 90 × 0.20 = 18
Quizzes: 80 × 0.30 = 24
Total Weighted Points: 18 + 24 = 42
The completed weight is:
Therefore, the current weighted grade is:
So the current weighted grade is 84.00%.
If you simply need the average of several grades where every grade has equal importance, use our Average Grade Calculator.
Weighted Grade Formula
The general weighted grade formula is:
When all category weights add up to 100%, you can calculate the final weighted grade by multiplying each grade by its decimal weight and adding the results.
Current Weighted Grade Formula
When only part of the course has been completed, use the completed weight to calculate your current weighted grade:
The calculator uses these calculations automatically so you do not have to perform the calculations manually.
Weighted Grade Calculation Example
Suppose you have completed the following two categories:
| Category | Grade | Weight |
|---|---|---|
| Homework | 90% | 20% |
| Quizzes | 80% | 30% |
First, calculate the weighted points for each category:
80 × 0.30 = 24
Add the weighted points:
The completed course weight is:
Now calculate the current weighted grade:
How to Calculate Grades by Weight
To calculate grades by weight, multiply each grade by its assigned weight and then add the weighted values together. The weight shows how much each category contributes to your overall course grade.
For example, suppose your homework is 25% of your grade, quizzes are 25%, and exams are 50%. If your grades are 90% for homework, 80% for quizzes, and 85% for exams, you can calculate your weighted grade as follows:
Homework: 90 × 0.25 = 22.50
Quizzes: 80 × 0.25 = 20.00
Exams: 85 × 0.50 = 42.50
Add the weighted values together:
Therefore, the weighted grade is 85.00%.
| Category | Grade | Weight | Weighted Points |
|---|---|---|---|
| Homework | 90% | 25% | 22.50 |
| Quizzes | 80% | 25% | 20.00 |
| Exams | 85% | 50% | 42.50 |
| Total | — | 100% | 85.00% |
The larger the weight, the greater the effect that category has on your overall grade. This is why a high exam weight can have a bigger impact on your final grade than a lower-weight homework category.
If you want to calculate your weighted grade automatically, enter each category’s grade and weight in our Weighted Grade Calculator.
Suppose your homework grade is 90% and is worth 25% of your course grade, your quiz grade is 80% and is worth 25%, and your exam grade is 85% and is worth 50%.
Calculate each weighted contribution:
Quizzes: 80 × 0.25 = 20.00
Exams: 85 × 0.50 = 42.50
Add the weighted values together:
Therefore, the weighted final grade is 85.00%. This method is useful when your grades have different weights and you need to calculate your overall course grade.
How Do Missing Assignments Affect a Weighted Grade?
A missing assignment can affect your grade depending on how your school or instructor handles missing work. If a missing assignment receives a zero, it can reduce the grade of its category and potentially lower your overall course grade.
The effect is generally larger when the assignment belongs to a category with a higher weight. For example, a missing exam can have a much greater effect than a missing homework assignment if exams represent a larger percentage of the course.
How to Calculate What You Need on Remaining Work
If you know your current grades and the amount of the course you have completed, you can calculate the score needed on your remaining work to reach a target grade.
Our Weighted Grade Calculator makes this easier. Enter your current categories and their weights, then enter your desired percentage in the Target Grade field.
For example, if your current weighted grade is 84%, you have completed 50% of the course, and you want a final grade of 90%, the calculator can determine the grade required on the remaining 50%.
If your question is specifically about the grade you need on a final exam, you can also use our Final Exam Calculator.
Weighted Grade Calculator Example
Consider a course with these grading categories:
| Category | Grade | Weight |
|---|---|---|
| Homework | 92% | 20% |
| Quizzes | 85% | 20% |
| Projects | 90% | 20% |
| Exams | 88% | 40% |
The final weighted grade is calculated by multiplying each grade by its decimal weight and adding the results:
= 88.60%
Therefore, the student’s weighted course grade is 88.60%.
Weighted Grade vs. Average Grade
A weighted grade and a simple average are not always the same. A simple average gives every grade equal importance, while a weighted grade gives different levels of importance based on the assigned weights.
| Weighted Grade | Simple Average |
|---|---|
| Categories have different weights. | Grades usually have equal importance. |
| Higher-weight categories have more influence. | Each grade contributes equally. |
| Useful for courses with weighted categories. | Useful when grades have equal value. |
If all of your grades have equal importance, our Average Grade Calculator may be more appropriate.
What Is a Good Weighted Grade?
What counts as a good grade depends on your school, course, grading system, and academic goals. In many courses, a percentage in the 90s is considered excellent, while an 80s percentage is commonly considered good.
However, grading scales differ between schools and instructors. Always check your course syllabus for the grading scale used in your class.
Frequently Asked Questions
How do I calculate a weighted grade?
Multiply each grade by its corresponding decimal weight and add the weighted values together. If you are calculating a current grade before the course is complete, divide the weighted points by the completed course weight.
What is a weighted grade?
A weighted grade gives different categories different levels of importance. A category worth 40% of a course affects the final grade more than a category worth 10%.
Can I calculate a weighted grade if the course is not finished?
Yes. Enter the grades and weights that have been completed. The calculator can show your current weighted grade and the percentage of the course that remains.
How do I find the grade I need to reach a target?
Enter your current grades and weights, then enter your desired grade in the Target Grade field. The calculator will determine the percentage you need on the remaining course work when the target is achievable.
Do weighted grades affect my GPA?
A weighted course grade may be used to determine your course result, but how it affects GPA depends on your school’s grading and GPA policy. For GPA calculations, use the grading rules provided by your school.
What happens if my category weights do not add up to 100%?
If you are calculating a current grade, the calculator can work with the portion of the course that has been completed. It shows both your completed weight and remaining weight. The total completed weight, however, cannot exceed 100%.
