Grade Point: โ
Enter a percentage between 0 and 100 to see your grade.
Enter a percentage into the calculator above to instantly see your letter grade and grade point. Below, you'll find the grading scale it uses, a worked example, and โ for courses where assignments carry different weights โ how to project the final exam score you need using our Final Grade Calculator guide.
A grade calculator works backward from your target course grade to tell you what score you need on a remaining assignment or final exam. Instead of waiting to see your grade after the fact, you can plan exactly how much the final needs to count for.
Most courses don't weigh every assignment equally. Homework might count for 20% of your grade, a midterm for 30%, and a final exam for the remaining 50%. A grade calculator accounts for that weighting rather than treating every score the same.
Enter a percentage score and the calculator matches it against the grading scale below to return a letter grade and grade point instantly โ no weights or components required. If your course grade is made up of several weighted assignments and you want to know what you need on a remaining final exam, that's a different calculation, covered in our Final Grade Calculator guide (illustrated below for reference).
Current Grade = ฮฃ (Component Score ร Component Weight)
Score Needed on Final = (Target Grade โ Current Grade) รท Final's Weight
Weights are expressed as decimals in the first formula (a 30% weight is 0.30) and as a percentage in the second, so it's worth being consistent as you work through the numbers by hand.
This example walks through a weighted course grade by hand โ the calculator above doesn't take weights as input, so if you want this computed automatically, use our Final Grade Calculator. Say a course is broken down like this, with the final exam still remaining:
| Component | Weight | Score |
|---|---|---|
| Homework | 20% | 92% |
| Midterm Exam | 30% | 78% |
| Class Participation | 10% | 88% |
| Final Exam (remaining) | 40% | ? |
Current weighted grade so far: 50.6%
Weight remaining for final exam: 40%
Target overall grade: 85%
Score needed on final = (85 โ 50.6) รท 40 ร 100 = 86.0%
This student needs roughly 86% on the final exam to reach an overall 85% in the course, based on their current standing.
Using the same current grade of 50.6% and a final worth 40%, here's what a few different target grades would require:
| Target Overall Grade | Score Needed on Final |
|---|---|
| 90% | 98.5% |
| 85% | 86.0% |
| 80% | 73.5% |
| 70% | 48.5% |
These numbers are based on the example above. Use the calculator with your own scores and weights for an accurate result.
A component worth 30% needs to be multiplied by 0.30, not 30, when calculating its contribution to your overall grade. Mixing this up throws off every number after it.
A homework worth 10% of your grade doesn't affect your final grade the same way a midterm worth 30% does. Always check your syllabus for the actual weight breakdown.
If your syllabus allows you to drop your lowest quiz score, or offers extra credit, factor that in before calculating what you need on remaining assessments.
A grade calculator solves for what you need in one course. If you want to see how that grade affects your overall semester performance, you'll need our GPA Calculator as well.
Don't estimate assignment weights. A syllabus usually states the exact percentage each component contributes to your final grade.
Knowing what score you need in advance lets you adjust your study time accordingly, rather than finding out after it's too late to change anything.
Some courses cap the maximum grade or apply a curve to the final exam. Confirm whether either applies before treating a calculated number as guaranteed.
Update your numbers every time a new assignment or exam grade is posted so your target for the final stays accurate.
The questions students ask most often about calculating course grades and final exam requirements.
Multiply each completed component's score by its weight and add them together to get your grade so far. Subtract that from your target grade, then divide by the final exam's weight to find the score you need on the final.
Multiply each assignment or exam's score by its percentage weight in the course, then add all of those weighted values together. The result is your overall weighted grade for the course.
This means your target grade isn't mathematically possible given your current scores and the final's weight, unless your course offers extra credit or a curve. Check with your instructor about any available options.
Most US schools use a scale similar to: 90% and above is an A, 80โ89% is a B, 70โ79% is a C, 60โ69% is a D, and below 60% is an F, though exact cutoffs vary by school.
You can factor in extra credit manually by adding it to your current weighted total before calculating what you need on the final. The calculator itself works from the scores and weights you enter.
This depends entirely on your current standing and the final's weight in the course. A student close to their target grade may only need a moderate final exam score, while someone further behind may need close to a perfect score.
It varies by course and institution, but final exams commonly count for 20% to 40% of the overall course grade. Always check your specific syllabus rather than assuming a standard weight.
Yes. If you only have one remaining test and know its weight along with your current grade, the same formula applies regardless of how many components make up the rest of the course.
Multiply each completed assignment or exam's score by its weight, then add those weighted values together. That total is your current grade, based only on the work you've completed so far.
Your final course grade will be lower than your target, calculated using the actual formula: your current weighted grade plus your actual final score multiplied by its weight. The exact drop depends on how far below your target the final score falls.
A grade calculator turns a vague goal like "do well on the final" into a specific number you can actually study toward. The calculator above solves the weighted formula instantly, and understanding the math behind it means you'll know exactly where you stand before the exam, not after.
Scroll up, enter your current scores and weights, and see exactly what you need on your final.
