Grade Calculator
Calculate your weighted course grade, estimate your letter grade and see what score you need on a remaining exam or assignment.
What Grade Do I Need?
Enter your current grade, the weight of the remaining item and your desired final grade.
| Current Grade (%) | |
| Remaining Weight (%) | |
| Desired Final Grade (%) |
Free Online Grade Calculator
UtiliPilot’s grade calculator helps students calculate weighted grades from assignments, quizzes, projects, exams and other course components. Enter each score and its percentage weight to calculate the current weighted average instantly.
How to Use the Grade Calculator
- Enter a name for each assignment or grade category.
- Enter the score you received as a percentage.
- Enter how much that item contributes to the final course grade.
- Add more rows when needed.
- Click Calculate Grade to see the weighted average and an estimated letter grade.
Weighted Grade Formula
For each item, multiply the grade by its weight expressed as a decimal. Add all weighted contributions together, then divide by the total included weight when the entered items do not yet represent 100% of the course.
Weighted Grade = Σ(Grade × Weight) ÷ Σ(Weights)
For example, if homework is 90% and worth 30% of the course, its weighted contribution is 90 × 0.30 = 27 percentage points.
Practical Example
| Item | Score | Weight | Contribution |
|---|---|---|---|
| Homework | 92% | 25% | 23.0 |
| Midterm | 84% | 35% | 29.4 |
| Final Exam | 88% | 40% | 35.2 |
The total weighted grade in this example is 87.6%.
How to Calculate the Grade You Need
If part of your course is still unfinished, the second calculator estimates the score needed on the remaining assignment or exam to reach a desired final grade. It uses your current average, the percentage already completed and the remaining weight.
Needed Score = (Target − Current × Completed Weight) ÷ Remaining Weight
If the required score is above 100%, the target is mathematically out of reach without extra credit or a grading adjustment. If the result is below 0%, you have already secured the target based on the values entered.
Typical Letter Grade Scale
| Percentage | Estimated Letter Grade |
|---|---|
| 90–100 | A |
| 80–89.99 | B |
| 70–79.99 | C |
| 60–69.99 | D |
| Below 60 | F |
Schools and instructors may use different grading scales, plus/minus grades or curved grading. Always check your syllabus for the official scale.
Factors That Affect the Result
An unweighted average gives every score equal importance. A weighted grade gives some assignments or categories more influence than others. Final exams, projects or major assessments often carry larger weights than homework or quizzes.
Grade Calculator vs GPA Calculator
A grade calculator estimates performance within a course, while a GPA Calculator converts multiple course grades and credit hours into a grade point average. You may use both tools during the same semester for different purposes.

Frequently Asked Questions
How do I calculate my weighted grade?
Multiply each score by its percentage weight, add the weighted contributions, and divide by the total included weight when necessary.
What if my entered weights do not add up to 100%?
The calculator normalizes the entered items to the total weight you supplied and also displays that total so you can see whether the course is complete.
Can I calculate what I need on my final exam?
Yes. Enter your current grade, the final exam’s course weight and your desired overall grade in the What Grade Do I Need section.
