How Weighted Grades Work
Most classes don't treat every assignment equally. Your syllabus breaks the course into categories — something like homework (20%), midterm (25%), final exam (30%), participation (10%), project (15%). Those percentages are the weights. They add up to 100% and determine how much each category pulls on your final grade.
A 90% on your final exam (worth 30%) helps your grade a lot more than a 90% on homework (worth 20%).
The Calculation
For each category: multiply your score by the category weight. Then add them all up. For example:
| Category | Score | Weight | Contribution |
|---|---|---|---|
| Homework | 92% | 20% | 18.4 |
| Midterm | 85% | 25% | 21.25 |
| Final Exam | 78% | 30% | 23.4 |
| Participation | 95% | 10% | 9.5 |
| Project | 88% | 15% | 13.2 |
| Total | 100% | 85.75% |
Common Grading Scales
| Percentage | Typical Letter Grade |
|---|---|
| 93–100% | A |
| 90–92% | A- |
| 87–89% | B+ |
| 83–86% | B |
| 80–82% | B- |
| 77–79% | C+ |
| 73–76% | C |
| 70–72% | C- |
| 67–69% | D+ |
| 60–66% | D |
| Below 60% | F |
Your professor's scale might differ. Check your syllabus — some professors set 90% as an A, others use 93%. When in doubt, use the scale from your syllabus.
What If I Don't Know All My Grades Yet?
That's fine. Enter the categories you know. The calculator will show your grade based on completed work only. This is useful mid-semester when you want to know where you stand before the final.
If you want to know what you need on an upcoming assignment to hit a certain grade, use our Final Grade Calculator — it's built for exactly that question.

Frequently Asked Questions
Multiply each category score by its weight (as a decimal), then add them all up. For example, if homework is 20% of your grade and you have a 90%, that contributes 0.20 × 90 = 18 points toward your final grade. Our calculator does this for every category automatically.
It means not every assignment counts equally. Your syllabus assigns weights (percentages) to different categories. The final exam at 30% matters more than participation at 10%. The weights tell you how much each part of the class pulls on your final grade.
Either your syllabus has a typo, there's a category you're missing, or there's a bonus component. Our calculator normalizes whatever you enter, so it'll still give you an accurate result based on the proportions of what you've entered.
Yes. Enter only the categories you have grades for. The calculator will show your grade based on completed work. This is useful for checking where you stand mid-semester.
Check your syllabus — there's usually a "Grading" or "Grade Breakdown" section that lists each category and its percentage. If you can't find it, ask your professor or check your school's LMS (Canvas, Blackboard, etc.).
This calculator gives you a percentage. Your professor then converts that percentage to a letter grade using their specific scale. A 90% might be an A in one class and an A- in another. Always check your syllabus for the grading scale.
