Calculate Your Weighted Course Grade
Use one row per assignment category or individually weighted item. The syllabus and official gradebook control missing work, exclusions, extra credit and letter-grade cutoffs.
No active weighted-grade result.
Calculation steps
- Enter completed and future categories, then select Calculate Grade.
A blank or future score is not treated as zero. Enter a missing category with the Missing, counts as zero status.

How to Use the Weighted Grade Calculator
- Choose a score entry method. Enter category percentages directly, or enter total earned and possible points for each category.
- Add the grading categories. Use one row for homework, quizzes, projects, exams or another syllabus category.
- Set each status. Completed work needs a score. Future work has no score yet. Missing work is an explicit zero. Excluded work contributes nothing.
- Enter course weights. Regular category weights should total the course policy, normally 100%. Mark only a true extra-credit category as extra credit.
- Add your planning values. Enter a target grade and an assumed average for remaining regular and future bonus work.
- Calculate and review. Check the normalized current grade, course points secured, remaining weight, projection, required average and row breakdown.
Weighted Grade Formula
For each completed regular category, convert the category score to a percentage, multiply it by the category weight and divide by 100. The result is the number of percentage points the category contributes to the full course grade.
The current grade normalizes only graded regular work. Course points secured measure direct progress toward the full course total. Those values differ whenever part of the regular course weight is still ungraded. The calculator keeps exact entered decimals and supported simple fractions, then applies the selected display rule only at the end.
Worked Weighted Grade Example
Assume a course uses four completed categories and one future final exam.
| Category | Score | Weight | Contribution |
|---|---|---|---|
| Homework | 92% | 20% | 18.40 points |
| Quizzes | 88% | 15% | 13.20 points |
| Midterm | 84% | 25% | 21.00 points |
| Project | 90% | 20% | 18.00 points |
| Final exam | Future | 20% | Not earned yet |
The four completed categories secure 70.60 course percentage points across 80% completed weight. The normalized current grade is 70.60 ÷ 80 × 100 = 88.25%. A 92% final-exam score would add 18.40 points and produce an 89.00% course grade. Reaching 90% requires 97% on the remaining 20%.
Enter Category Percentages or Points
Percentage mode accepts a category average such as 87.5. Points mode first calculates the category percentage from the entered totals.
Suppose homework contains assignments worth different numbers of points. If you earned 8/10 and 90/100, use 98 earned out of 110 possible. The category average is approximately 89.09%. A simple average of 80% and 90% would give 85%, which is wrong when the assignments are points-weighted.
Points mode on this page derives each category average. It does not turn the whole course into a total-points gradebook. The separate Grade Calculator serves a points-based course policy once that page is published.
Current Grade vs Course Points Secured
A current grade usually excludes future work. If completed categories carry 60% of the course and have produced 52.40 course percentage points, the normalized current grade is 52.40 ÷ 60 × 100, or approximately 87.33%. The student has not earned 87.33 points toward the full course. The secured amount remains 52.40 points.
The projected grade applies your assumed remaining average to future regular weight, any unentered regular weight below 100% when no excluded row is present, and future extra-credit rows. It is a scenario, not a prediction.
Target Grade and Remaining Average
The required result is one average across all remaining regular weight and any listed future extra-credit weight. It does not claim that every future assignment needs the same score.
A result at or below zero means the target is already secured even if remaining work earns zero. A result above 100% requires above-100 scores or extra credit. When no effective future weight remains, the result is fixed and there is no remaining average to solve.
If the final exam is the only effective future weight, the required average equals the required final-exam score. When several categories remain, it is their common weighted average under this planning model. Confirm late work, replacement exams and special category rules separately.
What If Regular Weights Do Not Equal 100%?
Regular course weights usually total 100%. The calculator compares the exact decimal total, so 33.33 + 33.33 + 33.34 equals 100 without a floating-point mismatch.
- Below 100%: when no excluded row is present, the difference is treated as unentered future regular work for the projection and target calculation. Current graded work remains valid.
- Exactly 100%: the regular plan is complete. Future rows make up the remaining regular weight.
- Above 100%: the regular plan is overallocated and calculation stops. Mark only the amount your policy defines as extra credit with an extra-credit status.
- Excluded rows: the row contributes no score or weight. When one is present, the calculator requires active regular and future rows to total 100% instead of guessing how the policy redistributes the excluded weight.
Some learning systems renormalize empty categories while others require the configured categories to total 100%. Match the interface to the actual syllabus and gradebook settings.
Extra Credit and Scores Above 100%
Extra credit appears in more than one form. A score can exceed its ordinary maximum, such as 105/100. A separate bonus category can also add percentage points without entering the regular 100% denominator. This calculator supports both only when you identify them explicitly.
Select the above-100 checkbox before entering a category score or assumed future average over 100%. For a separate bonus category, choose Extra credit, graded or Extra credit, future. Its weight is additive and does not repair a regular weight plan below 100%.
Dropped, Missing, Excused and Future Work
- Dropped assignment: recalculate the category total after the official drop rule, then enter the resulting category percentage or points.
- Missing assignment: choose Missing, counts as zero when the official gradebook includes the zero and its category weight remains active.
- Excused category: choose Excluded / excused. The row is omitted rather than treated as zero.
- Future category: choose Future / ungraded. It is excluded from the current grade and included in planning.
- Blank row: a completely blank default row is ignored. A partially entered row must be completed or explicitly excluded.
Drop-lowest rules can depend on point values rather than the lowest percentage. Apply the official rule inside the learning system before summarizing the category here.
Weighted Grade vs Points Grade and Weighted GPA
A weighted course grade gives each assignment or category an explicit share of the course percentage. A points-based grade divides all earned points by all possible points, so high-point assignments have more influence automatically. These methods agree only in special cases.
Weighted GPA is different again. GPA calculations use grade-point values and GPA-bearing course credits, sometimes with an Honors, AP or IB bonus. This page does not use grade points, credit hours or automatic letter-grade conversions.
Rounding and Precision
The calculator preserves exact decimal and simple-fraction inputs while converting points, multiplying weights and adding contributions. It rounds only the displayed values. Round half to even sends an exact halfway result to the nearest value whose last retained digit is even. Round half up increases an exact halfway magnitude. Truncate removes later digits without increasing the retained magnitude.
Your official gradebook may store more precision, round each assignment, round category averages, truncate, or display a value different from the one used internally. Match its published rule when available.
Common Weighted Grade Mistakes
- Averaging category percentages without applying their different course weights.
- Calling course points secured the current normalized grade.
- Treating future or excused work as a zero without checking the policy.
- Leaving a missing zero out of the completed-weight denominator.
- Averaging unequal-point assignments equally inside a category.
- Entering 0.20 when the interface expects a 20% weight.
- Letting regular weights exceed 100% instead of identifying the true bonus category.
- Rounding every category contribution before adding the total.
- Converting the percentage to a letter grade with an unofficial cutoff.
- Using course-grade weights as GPA credit hours.

Weighted Grade Calculator FAQs
How do I calculate a weighted grade?
Multiply each category percentage by its course weight, divide by 100, then add the contributions. For a current grade, divide the regular weighted score sum by completed regular weight, then add completed bonus contributions.
What formula does the calculator use?
Each course contribution equals score percentage times weight percentage divided by 100. The current grade normalizes completed regular work and then adds completed extra-credit contributions.
Do regular grade weights have to add up to 100%?
A literal weighted-course policy normally totals 100%. If entered regular weights are below 100% and no excluded row is present, this tool treats the difference as future work. If an excluded row is present, active regular weights must total 100%. Above 100%, calculation stops until true extra credit is marked separately.
What happens when entered weights total less than 100%?
When no excluded row is present, the completed-work current grade remains available, course points secured stay unnormalized, and the unentered difference joins future work in the projection and target calculation. With an excluded row, the calculator stops until the gap is assigned or redistributed explicitly.
What happens when regular weights total more than 100%?
The calculator reports an overallocated plan. Change incorrect weights or mark a genuine additive category with an extra-credit status. Extra-credit weight stays outside the regular 100% total.
How do I calculate a category grade from several assignments?
When the category is points-based, add earned points, add possible points, divide earned by possible, then multiply by 100. Do not average assignment percentages equally unless the policy says they carry equal weight.
Is a weighted grade different from a simple average?
Yes. A simple average gives every entered percentage equal influence. A weighted grade gives more influence to rows with larger weights.
What is the difference between a weighted grade and weighted GPA?
A weighted grade combines course percentages and assignment or category weights. Weighted GPA combines grade points, course credits and any eligible course-level bonus defined by the institution.
Should ungraded, missing or excused work count as zero?
Not automatically. Future work is excluded from the current grade, Missing is an explicit zero, and Excluded contributes nothing. Your instructor or learning system determines the official treatment.
Does the calculator convert the result to a letter grade?
No. Letter-grade thresholds differ by course and institution. Compare the calculated percentage with the grading scale in the current syllabus.
Methodology and Sources
The category formula and empty-group normalization were checked against the official Canvas weighted assignment-group guide. Category setup was checked against Google Classroom grading help and Microsoft Teams weighted grading guidance. Empty-grade, weighted-mean and extra-credit distinctions were checked against Moodle grade aggregation. Dropped-score and extra-credit behavior were reviewed against the official Canvas assignment-group rules and Canvas extra-credit guide.
These systems do not use one identical policy. The calculator exposes its assumptions and never claims to reproduce a specific gradebook without matching inputs and settings.
Important Note
This calculator is for educational planning. It does not issue an official course grade, interpret a syllabus, decide whether work is missing or excused, apply a private gradebook rule, or determine academic standing, credit, eligibility, admission or graduation. Your instructor and official learning system control the recorded result.
