How to use the weighted grade calculator
- Open your syllabus and find how each part of the class is weighted, such as homework 20% or the midterm 25%.
- Enter each category with your current grade as a percentage and its weight.
- Read your weighted grade on the right. It updates as you type and shows the matching letter grade.
- Leave out categories that haven't been graded yet. The calculator then shows your grade for the work completed so far.
How weighted grades are calculated
In a weighted class, each category counts toward your grade in proportion to its weight. A midterm worth 25% moves your grade more than a quiz average worth 10%. To find the weighted grade, multiply each grade by its weight, add those results, then divide by the total weight.
Dividing by the total weight is what makes the result work mid-semester. If only 80% of the course has been graded, the calculator scales your result to that 80% instead of treating the missing 20% as zeros.
Worked example
Homework 92% × 20 = 1,840 · Quizzes 85% × 20 = 1,700 · Midterm 78% × 25 = 1,950 · Projects 95% × 15 = 1,425
Total: 6,915 ÷ 80 (the weight graded so far) = 86.44%, a B.
A plain average of the same four scores is 87.5%. The weighted result is lower because the midterm, the lowest score, also carries the most weight.
Weights as percentages or points
Some teachers use points instead of percentages. For example, homework might be worth 200 points out of 1,000 for the course. You can enter those numbers directly as weights (200, 300, 500). The formula divides by the total, so points and percentages give the same answer.
Letter grade scale
The letter grade shown uses the most common U.S. scale. Your school may set the cutoffs a point or two differently, so check your syllabus.
| Percent | Letter | GPA points |
|---|---|---|
| 97–100 | A+ | 4.0 |
| 93–96 | A | 4.0 |
| 90–92 | A− | 3.7 |
| 87–89 | B+ | 3.3 |
| 83–86 | B | 3.0 |
| 80–82 | B− | 2.7 |
| 77–79 | C+ | 2.3 |
| 73–76 | C | 2.0 |
| 70–72 | C− | 1.7 |
| 67–69 | D+ | 1.3 |
| 63–66 | D | 1.0 |
| 60–62 | D− | 0.7 |
| Below 60 | F | 0.0 |
Tips for raising a weighted grade
- Spend your effort where the weight is. Raising a 40% category by 5 points lifts your grade by 2 points; the same gain in a 10% category adds only 0.5.
- Use the final grade calculator to see exactly what you need on the last exam.
- Ask whether your teacher drops the lowest quiz or homework score. That can change a category average noticeably.
Frequently asked questions
What is a weighted grade?
A weighted grade is a course grade where each category, such as homework, quizzes or exams, counts by a set percentage instead of equally. Each score is multiplied by its weight, the results are added, and the sum is divided by the total weight.
What if my weights don't add up to 100%?
That usually means part of the course hasn't been graded yet. The calculator divides by the weight you entered, so the result is your grade for the work completed so far. If your weights add up to more than 100%, check your syllabus for a mistake.
How do I calculate my grade with points instead of percentages?
Enter the points each category is worth as its weight, for example 200 for homework and 500 for exams. Because the formula divides by the total weight, points work exactly like percentages.
Is a weighted grade the same as a weighted GPA?
No. A weighted grade is your percentage in one class based on category weights. A weighted GPA adds extra points for Honors, AP or IB classes. Use the GPA calculator for that.
What letter grade is an 86%?
On the standard U.S. scale, 83% to 86% is a B and 87% to 89% is a B+. Schools can set their own cutoffs, so check your syllabus.
