Weighted Grade Calculator — Live Course Tracker

How to Use This Grade Calculator

1. The calculator opens with sample entries — replace them with your own, and click "Add item" or "Add another item" to create a row for every graded component in your course (homework, quizzes, midterm, final exam, projects, and so on).
2. Optionally name each item, for example "Midterm Exam", so you can recognize it later.
3. Enter your score for each item as a percentage. If your score is not out of 100, convert it first (18 out of 20 becomes 90).
4. Enter each item's weight exactly as listed in your syllabus. For a final course grade, the weights should total 100%.
5. Watch the results panel update live with your overall percentage and letter grade; the note below it tells you whether your weights are under, at, or over 100%.
6. Use the Copy or PDF buttons in the results panel to save your grade. Your rows are stored automatically in your browser, so you can leave and pick up where you left off.

How Grades Are Calculated

Most courses grade you with a weighted average: every assessment contributes to your final grade in proportion to its weight. Multiply each score by its weight, then add the results together:

Final Grade = Σ(Assignment Score × Assignment Weight)

In simple terms, a score on a heavily weighted exam counts many times toward your grade, while a lightly weighted quiz counts only a little. When your weights add up to exactly 100%, the sum above is your final grade. If you have only completed part of the course, this calculator divides by the weight you have entered so far — Grade = Σ(Score × Weight) ÷ Σ(Weight) — giving your true average on work completed. In an unweighted course, every item simply gets the same weight, and the formula reduces to a plain average of your scores.

Example Grade Calculation

Suppose your syllabus weights the course like this, and these are your scores:

Component	Weight	Score	Weighted Points
Homework	25%	90%	22.5
Midterm	35%	82%	28.7
Final Exam	40%	88%	35.2
Final Grade			86.4%

The calculation: (90 × 0.25) + (82 × 0.35) + (88 × 0.40) = 22.5 + 28.7 + 35.2 = 86.4%, which corresponds to a B on the common letter scale below. Notice how the 82% midterm barely dents the final result — its 35% weight softens the blow — while the strong 40%-weighted final exam pulls the average up. If the final exam had not happened yet, entering just the first two rows (60% of the weight) would still show your accurate mid-term average of 85.3%.

Grade Reference Table

Letter grade cutoffs vary between schools, colleges, and countries, so no single table fits everyone. The ranges below reflect the common US-style letter scale that this calculator uses to label your result; always confirm the official boundaries in your own course syllabus or student handbook.

Letter Grade	Typical Percentage Range
A	93–100%
A−	90–92%
B+	87–89%
B	83–86%
B−	80–82%
C+	77–79%
C	73–76%
C−	70–72%
D	60–69%
F	Below 60%

Many institutions adjust this scale — for example, some award an A+ for 97–100%, others split the D band into D+ and D−, and some skip plus/minus grades entirely. The percentages, not the letters, are the reliable part: your weighted average stays correct no matter which lettering scheme your institution prefers.

Who Should Use This Tool?

• High school students tracking report-card standing across quizzes, tests, and projects — and converting raw scores with the Percentage Calculator first.
• College students checking where they stand between midterms, or pairing this tool with the Final Grade Calculator to see the exam score needed for a target grade.
• University students watching multiple weighted courses at once — turn each course grade into grade points with the GPA Calculator, track your degree standing with the CGPA Calculator, and model what-if scenarios in the GPA Simulator.
• Online learners in self-paced courses and MOOCs, where graded items often unlock over time and participation rules apply — keep eligibility in check with the Attendance Calculator.
• Teachers double-checking weighted gradebook results quickly, or showing students exactly how much an upcoming exam can move their grade.
