Grade Calculator

See where you stand in any course. Enter each assignment or exam with the score you received and the maximum possible score — the Grade Calculator averages them using the total-points method and shows your current percentage and letter grade.

  • Course 1

Current course grade

Add assignments with your score and the maximum score.

How it works

  1. Add a row for each graded item: quiz, assignment, midterm, lab, project.
  2. Enter your score and the maximum score for each item.
  3. All scores are summed and divided by the sum of all maximums.
  4. The result is your current overall percentage plus its letter grade.

The formula

Current grade (points method)

grade % = Σ scores ÷ Σ maximum scores × 100

This matches how most courses compute totals — every point carries equal weight, so a 50-point midterm moves your grade twice as much as a 25-point quiz.

Worked example

Worked example

  1. Quiz 1: 18/20 · Midterm: 41/50 · Lab report: 28/30
  2. Total score = 18 + 41 + 28 = 87; total max = 20 + 50 + 30 = 100

Current grade = 87% — a B+ with this letter scale.

Common mistakes

  • Using a simple average of percentages — averaging 90% (on 10 points) with 70% (on 100 points) treats them equally, which is rarely correct.
  • Entering scores out of different maximums and comparing them directly.
  • Forgetting graded items that carry no points but affect your standing.

Frequently asked questions

What if my course uses weighted categories instead of points?

Use the weighted grade calculator — it lets you assign a percentage weight to each category (homework 20%, midterm 30%, final 50%).

What letter grade is 87%?

On the common 10-point scale used here, 87% is a B+. Scales differ between universities — check your syllabus.

Can I use this to predict my final grade?

For a prediction, add your expected scores on remaining items — or use the final grade calculator, which accounts for how much the final is worth.
