Enter each assignment or category with its grade and weight to see your current course grade as a percentage and a letter. Grades can be percentages (88), points (44/50) or letters (B+). Leave the weights blank for a simple unweighted average, and the planner below the result shows the score you need on the rest of the course.
Calculate your course grade
Weighted grade = (90 × 20 + 85 × 20 + 78 × 25 + 92 × 15) ÷ (20 + 20 + 25 + 15) = 6830 ÷ 80 = 85.38%. Letter grade B (3.0 on a 4.0 scale).
Your weights add up to 80%, so this is your grade on the work graded so far. The remaining 20% is still open (see the planner below).
To finish with 85% (B), you need 83.50% on the remaining 20% of the course: (85 × 100 − 6830) ÷ 20 = 83.50%. That is within reach.
How to use the grade calculator
- Add one row per assignment or grade category (homework, quizzes, midterm, final exam).
- Type the grade: a percentage, a points score such as 18/20, or a letter grade.
- Type the weight from your syllabus, for example 25 for a midterm worth 25% of the course. For points-based classes, leave every weight empty.
- Read your grade, letter and the working. Change any number and the result updates straight away.
- Set the course grade you want to see what you need on the part of the course that is not graded yet.
How your grade is calculated
Weighted grade = (grade₁ × weight₁ + grade₂ × weight₂ + …) ÷ (weight₁ + weight₂ + …). Each category counts in proportion to its weight, so a 25% midterm moves your grade five times as much as a 5% quiz.
Unweighted average = sum of grades ÷ number of grades, used when every item counts the same. Points grade = total points earned ÷ total points possible × 100, used when all scores are entered as points.
Worked example
| Category | Grade | Weight | Grade × weight |
|---|---|---|---|
| Homework | 90% | 20% | 1,800 |
| Quizzes | 85% | 20% | 1,700 |
| Midterm exam | 78% | 25% | 1,950 |
| Project | 92% | 15% | 1,380 |
| Total | 80% | 6,830 |
6,830 ÷ 80 = 85.38%, a B. The final exam (the remaining 20%) is not graded yet. To finish the course with an 85%, the student needs (85 × 100 − 6,830) ÷ 20 = 83.5% on the final.
Letter grade scale
Most US high schools and colleges use this plus/minus scale. Check your syllabus, because some schools start an A at 94% or drop the A+.
| Letter grade | Percentage | GPA points (4.0 scale) |
|---|---|---|
| A+ | 97–100 | 4.0 |
| A | 93–96 | 4.0 |
| A- | 90–92 | 3.7 |
| B+ | 87–89 | 3.3 |
| B | 83–86 | 3.0 |
| B- | 80–82 | 2.7 |
| C+ | 77–79 | 2.3 |
| C | 73–76 | 2.0 |
| C- | 70–72 | 1.7 |
| D+ | 67–69 | 1.3 |
| D | 63–66 | 1.0 |
| D- | 60–62 | 0.7 |
| F | Below 60 | 0.0 |
Weighted vs unweighted grades
If your teacher lists categories with percentages (“tests 50%, homework 20%”), your grade is weighted and you should fill in the weight column. If the gradebook just adds points, such as 430 out of 500, it is unweighted by points: enter scores as earned/possible and leave the weights empty. If every assignment counts equally, a plain average is enough, and the grade average calculator does exactly that.
What do I need on my final?
Use the planner above when your weights add up to less than 100%, or open the final grade calculator to see the score you need on the final exam for every letter grade from A to D. For multiple remaining tests, try the final exam grade calculator.

Frequently asked questions
How do I calculate my grade with weights?
Multiply each grade by its weight, add the results, then divide by the total of the weights. With homework 90 (20%), quizzes 85 (20%), midterm 78 (25%) and project 92 (15%) that is 6,830 ÷ 80 = 85.38%, a B.
What if my weights do not add up to 100%?
The calculator divides by the weights you entered, so the result is your grade on the work graded so far. The weight you have not entered yet is treated as still to come, and the planner shows what you need on it to reach a target grade.
How do I calculate my grade from points?
Type each score as earned/possible, for example 45/50, and leave the weight column empty. The calculator adds all points earned and divides by all points possible, which is how most points-based gradebooks work.
What letter grade is an 85%?
On the common US scale an 85% is a B (83–86%), worth 3.0 grade points. An 87% is a B+ and a 90% is an A-. Your school’s syllabus scale takes priority if it differs.
Can I enter letter grades instead of percentages?
Yes. A letter counts as the middle of its range: A+ = 98, A = 95, A- = 91.5, B+ = 88, B = 85 and so on down to D- = 61.5, with F counted as 50. If you know the exact percentage, type that instead for a precise result.
Is a weighted grade the same as a weighted GPA?
No. A weighted course grade combines assignments inside one class by their percentage weights. A weighted GPA adds extra points for honors or AP classes across your transcript; use the high school GPA calculator for that.
