Grade Calculator

Most courses don't count every assignment equally. A final exam might be worth 35% of the grade while each quiz is worth 5%. A weighted average multiplies each score by its weight, adds the results, and divides by the total weight:

Weighted average = (score₁ × weight₁ + score₂ × weight₂ + …) ÷ (weight₁ + weight₂ + …)

For example, with 92% on homework worth 20%, 85% on quizzes worth 20%, 78% on a midterm worth 25%, and 88% on a final worth 35%: (92×20 + 85×20 + 78×25 + 88×35) ÷ 100 = 85.7%.

If you only have some grades so far, enter just those. The calculator divides by the weight you have entered, so it shows your current average based on completed work. "Weight Entered" shows how much of the course that covers. To find what you need on a remaining exam, use the Final Grade Calculator.

Letter-grade cutoffs vary by school, so check your syllabus. A common US scale is:

• A: 90–100%
• B: 80–89%
• C: 70–79%
• D: 60–69%
• F: below 60%

Many schools also use plus and minus grades within each band, such as B+ for 87–89%. To turn letter grades into a GPA, use the GPA Calculator.
