Grade Calculator

Enter your scores and their weights to see your current course grade and what you need on the remaining work to hit a target.

How to use the Grade Calculator

  1. Enter the score and weight of each graded item.
  2. Add rows as needed; the weights do not have to total 100% yet.
  3. Enter a target final grade to see the score you need on the remaining work.

Weighted grade formula

Grade = Σ (score × weight) ÷ Σ weight

Homework 92% (weight 20), midterm 84% (weight 30) and project 88% (weight 20) give (92 × 20 + 84 × 30 + 88 × 20) ÷ 70 = 87.4%.

What do I need on the final?

Needed = (target × 100 − Σ (score × weight)) ÷ remaining weight

With the scores above and a final exam worth the remaining 30%, reaching 90% overall needs (90 × 100 − 6,120) ÷ 30 = 96%.

Letter grades

The letter shown uses a common scale: A 93+, 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. Your school’s scale may differ.

Frequently asked questions

How do I calculate a weighted grade?

Multiply each score by its weight, add the results and divide by the total of the weights.

How do I find the grade I need on my final?

Subtract the weighted points you already have from your target, then divide by the weight of the final exam.

What if my weights do not add up to 100%?

The calculator shows your grade for the work completed so far and treats the missing weight as work still to come.
