1. How to Use the Weighted Grade Calculator
Use the Weighted Grade Calculator when different parts of your course, such as homework, quizzes, and exams, contribute different percentages to your overall grade. It helps you calculate your current average, estimate your final course grade, and determine what scores you need on upcoming work.
1. Enter Your Graded Categories. Under Grade, enter your average for each category, and under Weight, enter the
percentage assigned to it in your syllabus. For example, if your homework average is 92% and homework accounts for
20% of your course grade, enter 92 and 20. You can add a category name if you want.
2. Include All Completed Categories. Click + Add Category to enter additional graded work. Use each category's overall average rather than adding individual assignments that are already included in that average. Leave categories with no grades yet out of your current-grade calculation.
3.Review Your Results and Plan Ahead. The calculator updates your results as you enter or change values. Use Try Sample Scores to explore an example and understand how different grades affect your average. If your school uses a particular letter-grade scale, check its grading policy to interpret your percentage correctly.
Find Each Category's Weight
Your score shows how well you performed, while the weight determines how much that performance affects your overall grade. For example, a 90% in a category worth 30% contributes more to your final grade than a 90% in a category worth 10%. Check your course syllabus or gradebook to find the correct weights.
Enter grades and weights as percentages. If you earned 45 points out of 50 on an assignment, calculate 45 ÷ 50 × 100 = 90% and enter 90 in the Grade field. The examples below explain how to calculate category averages and combine assignment scores correctly.
Biology example scores: Homework: 92%, Quizzes: 84%, Labs: 88%, and Midterm: 79%.
2. What Is a Weighted Grade?
A weighted grade is an average where different parts of a course contribute different amounts to your overall result.
For example, if exams make up 60% of your course grade and homework accounts for 20%, a one-percentage-point
increase in your exam average has three times the impact of the same increase in your homework average.
Formula
Weighted Grade (%) = Σ(Category Grade × Category Weight) ÷ Σ(Entered Category Weights)
Use percentage values consistently: enter 90 for a grade of 90% and 20 for a category weight of 20%.
If the category weights you enter add up to 100%, the result represents your overall course grade. If you include only
categories that have been graded and their weights total less than 100%, the result shows your average across the completed
portion of the course. The remaining, ungraded portion is not automatically counted as zero.

for each group before its assigned weight is applied. The instructor’s grading settings determine how category weights and ungraded assignments affect the final result.
Weighted grade vs. weighted GPA
Once your course grades are final, use the College GPA Calculator or Weighted GPA Calculator to combine them into GPA.
3. Weighted Grade Examples
Example 1: Calculating Your Final Course Grade
Imagine your syllabus assigns the following weights to each course category: Homework 20%, Quizzes 15%,
Midterm 25%, Final Exam 30%, and Participation 10%. Once all categories have been graded, you can multiply
each category average by its assigned weight and add the contributions to find your final course percentage.
The weighted contributions total 85.85%, which is a B on this calculator’s default plus/minus grading scale. By comparison,
the simple average is 87.8%. The difference occurs because a simple average treats every category equally, while
the weighted calculation follows your syllabus. For example, the final exam, worth 30% of your grade, has three times
the influence of participation, which is worth 10%.
Example 2: Calculating Your Current Grade Mid-Semester
Selecting Try Sample Scores loads three completed categories: Homework at 92% with a 20% weight, Quizzes at 85% with a 15% weight, and Midterm at 78% with a 25% weight. Together, these categories account for 60% of the total course grade.
You have earned 50.65 percentage points toward your overall course grade so far. However, your weighted average
across the completed 60% of the course is 84.42%. The remaining 40% is not included as zero because it represents
work that has not yet been graded.
An Ungraded Assignment Is Not the Same as a Zero
An upcoming exam with no score yet should generally be treated as ungraded work. In contrast, if you missed an exam and your instructor recorded a score of zero, that zero must be included in the calculation. Leaving out an actual zero can make your current average appear higher than it really is.
4.What Score Do You Need on the Final?
Open Plan My Final Exam, choose your desired result under Grade I Want, and enter the final exam’s percentage weight.
If you have multiple assessments left, you can use their combined weight when calculating the single average you need
across all remaining work.
Formula
Required Remaining Score = [Target Course Grade × 100 − Σ(Completed Category Grade × Weight)] ÷ Remaining Weight
Example 3: Reaching a 90% Course Grade
Using the sample scores, 60% of the course has been graded, while the remaining 40% includes the final exam
and participation. To achieve an overall grade of 90%, you need an average of:
If your participation grade is already confirmed at 100%, add it as a completed category. The final exam then becomes the only remaining assessment, worth 30% of the course. To reach 90%, your required exam score would be:This example shows why including all known grades is important: a confirmed participation score changes the average you need on the final exam.
Check the Highest Possible Grade
Before setting your target, calculate the best result you could achieve if you earned 100% on all remaining work.
In this example, scoring 100% across the remaining 40% would give you a maximum course grade of 90.65% (50.65 + 40).
Knowing this maximum helps you set a realistic goal and prioritize your study time based on the score you need.
5. Points, Extra Credit, and Dropped Grades
Calculating Grades From Points
To find a category average when assignments use points, add the points earned and divide them by the total points
possible. Then multiply the result by 100.
For example, suppose you scored 18 out of 20 on one homework assignment and 40 out of 50 on another.
Your category average is:
Simply averaging 90% and 80% gives 85%, but that method treats both assignments as equally important, even though
they have different point values.
If your course uses a total-points grading system without separate category weights, calculate your grade using total points earned ÷ total points possible × 100.
If you enter individual assignment percentages into this calculator, assign each one a weight based on its share of the
total possible points. Alternatively, use the Grade Calculator to work with your specific grading system.
Extra Credit, Dropped Scores, and Grade Curves
Extra credit: Follow your instructor’s grading rules before entering your scores. Bonus points added to an
assignment, points added directly to your course percentage, and a separate extra-credit category can affect
your grade in different ways.
Dropped scores: Apply any required drops before calculating each category average. In a points-based category,
the assignment that improves your total the most may not be the one with the lowest percentage.
Curves and rounding: Calculate your raw grade first, then apply the rounding or curve policy stated in your syllabus.
Do not assume that 89.5% automatically becomes 90%, since instructors and schools may use different rules and
letter-grade cutoffs.
6. Why does your result differ from the gradebook?
Frequently Asked Questions
How do you calculate a weighted grade?
Multiply each category grade by its assigned weight, add the contributions together, and divide by the sum of the weights entered. If the weights total 100%, the result is your overall course grade. If only completed categories are included, the result represents your average across the graded portion.
What is the difference between a weighted grade and a regular average?
A regular average gives every score equal importance, while a weighted grade considers how much each category contributes to your final result. For example, a final exam worth 30% affects your overall grade more than homework worth 10%, even if both have the same percentage score.
How do I calculate my current grade if some assignments are ungraded?
Enter the grades for completed categories and their corresponding weights. The calculator can determine your average across the graded portion without automatically counting the remaining coursework as zero. Make sure to include any assignments that your instructor has actually graded as zero.
How do I find out what grade I need on my final exam?
Enter your completed category grades, set your target course grade, and provide the final exam's weight. The calculator estimates the score needed to reach your goal. If other assessments remain, account for their weights and grades when calculating the required average across the remaining work.
Can weighted grades be higher than 100%?
A standard weighted average of category percentages between 0% and 100% will generally stay within that range when the weights are nonnegative. However, extra credit, bonus points, or special grading rules may allow a course percentage to exceed 100%, depending on your instructor's system.
