Free student calculator
Enter your grades and weights to get a clear result without digging through a long article first. The calculator stays at the top, works on mobile, and keeps each result easy to review.
Enter each grading category, its weight, and your grade. This calculator will estimate your current course grade, letter grade, GPA, and contribution breakdown.
| Category | Weight % | Grade % | Action |

Find out what grade you need on your final exam to reach your target course grade.
Use this assignment grade calculator when your class uses earned points and possible points instead of category weights.

Enter a percentage grade to estimate the letter grade and GPA using a common US grading scale.
Results are estimates. Check your syllabus or official gradebook when your school uses a different scale or extra-credit policy.
Start with the tab that matches your gradebook. For a weighted class, add one row for each category, such as homework, quizzes, tests, projects, and the final exam. Enter the percentage weight and your current grade for that category, then choose Calculate Grade.
The result separates your normalized grade from the amount already contributed toward the full course grade. That distinction matters when the entered categories do not yet add up to 100%.
Each category contributes part of its score to the course total. Convert the weight to a decimal, multiply it by the category grade, and repeat for every category.
Weighted contribution = category grade × (category weight ÷ 100)For example, a 92% homework grade with a 20% weight contributes 18.4 percentage points. A high-weight exam usually changes the course grade more than one low-weight homework category.
| Category | Grade | Weight | Contribution |
|---|---|---|---|
| Homework | 92% | 20% | 18.40 |
| Quizzes | 85% | 15% | 12.75 |
| Tests | 88% | 25% | 22.00 |
| Final exam | 90% | 30% | 27.00 |
| Participation | 100% | 10% | 10.00 |
These contributions add up to 90.15%. The calculator also gives a letter-grade and GPA reference, but your school’s cutoffs may be different.
The final-grade tab works backward from your target. Enter your current course grade, the grade you hope to finish with, and the final exam’s weight. The calculator then estimates the exam score needed.
A required score above 100% usually means the target cannot be reached through the final alone. A negative required score means the current grade has already secured that target, assuming the entered figures are correct.
Use weighted grades when the syllabus assigns percentages to categories. Use total points when the class simply divides all earned points by all possible points. Mixing the two methods can produce a misleading result.
When in doubt, check whether your syllabus says something like “Tests: 40%” or instead lists assignments as points such as “Exam: 100 points.”
Confirm that each weight belongs to the correct category, include only completed categories when checking a current grade, and verify whether extra credit sits inside a category or outside the normal 100% total.
It also helps to compare the result with the grade shown in your learning platform. Differences can come from dropped assignments, rounding, late penalties, or a custom grading scale.
A weighted grade gives some parts of a class more influence than others. A final exam may count for 30 percent while homework counts for 15 percent.
That usually means one or more categories have not been included yet. The calculator normalizes the completed categories so you can see your current standing.
Yes. A category grade can be above 100 percent, but the way extra credit affects an official grade depends on the teacher or school policy.
Use the weighted tab when your syllabus lists category percentages. Use the points tab when the gradebook is based on total earned points divided by total possible points.
No. It uses a common 4.0 scale as a quick reference. Your school may use different cutoffs, weighting rules, or GPA calculations.
