Weighted grade calculator

A weighted grade is the sum of each score multiplied by its weight, divided by the sum of the weights. Because it divides by the weights entered, they do not need to add up to 100, so you can see your current standing halfway through a course with only the graded work entered.

Worked example: four components graded so far

  1. 1Assignments 88 (weight 20): 20 × 88 = 1760. Midterm 74 (weight 30): 30 × 74 = 2220.
  2. 2Project 92 (weight 15): 15 × 92 = 1380. Quizzes 80 (weight 10): 10 × 80 = 800.
  3. 3Sum of weight × score = 1760 + 2220 + 1380 + 800 = 6160. Sum of weights = 20 + 30 + 15 + 10 = 75.
  4. 4Weighted grade = 6160 ÷ 75 = 82.13%.

Your current grade is 82.13% with 75% of the course graded; the final exam (the remaining 25%) decides the rest.

How do I calculate a weighted grade?

For each component, multiply the score by its weight. Add those products, then divide by the total of the weights you used. Scores should be on the same scale, usually percentages; convert raw marks like 18 out of 25 to 72% first. Dividing by the sum of weights rather than by 100 is what lets the formula work before every component has been graded.

Why don't my weights need to add up to 100?

Because the result is normalised by the weights you enter. Weights of 20, 30, 15 and 10 behave the same as 0.2, 0.3, 0.15 and 0.1, or as 8, 12, 6 and 4. Only the ratios matter. When every component is entered and the weights do sum to 100, the result is your final course grade; before that, it is your grade on the work graded so far.

Common mistakes

  • Averaging percentages without weights: a 10% quiz should not count as much as a 40% exam.
  • Mixing raw marks and percentages in the same calculation.
  • Forgetting dropped scores or a category cap described in the syllabus.
  • Treating ungraded work as zero when you want your current standing.
  • Entering a weight for a category that has not been graded yet, which drags the result down.

Weighted grade calculator: questions and answers

Is a weighted grade the same as a weighted GPA?

No. A weighted grade combines scores within one course using syllabus weights. A weighted GPA, used by some US high schools, adds extra points for honors or AP courses across your whole record. This page covers course grades; the GPA calculator covers the unweighted 4.0 scale.

How do I handle categories with several items?

Average the items inside the category first, then enter that average with the category weight. For example, five quizzes averaging 80 in a 10% category become one line: score 80, weight 10. If your course weights each item by points instead, enter each item with its points as the weight.

Can I see what I need on the remaining work?

Yes. Take the weighted grade here as your current grade, then open the final grade mode, enter the remaining weight and your target, and it shows the score you need. With 82.13% now and 25% remaining, an 85% overall needs (85 − 61.6) ÷ 0.25, about 93.6%.

Why does my portal show a different grade?

Portals sometimes count ungraded items as zero, apply drops automatically, or round differently. Compare the weights and scores line by line. If they match and the result still differs, ask your instructor how the portal grade is computed. Your instructor's gradebook is the official figure.
