About Grade Calculator

The Grade Calculator works out your current weighted grade in a course from the assignments you have completed. Enter each assignment’s score and its weight; the tool weights every score, divides by the total weight entered, and shows your percentage and the matching letter grade — updating live.

Because it divides by the weights you have actually entered, it works mid-semester: with only 60% of the course graded so far, you still get an accurate picture of where you stand. If your weights do not total 100%, the calculator notes it and weights by your totals.

Use it after each returned exam to track your standing, or together with a final grade calculator to plan what you need on remaining work. Unlimited assignment rows, free and instant in your browser.

How to use Grade Calculator

  3. Enter the assignment’s weight — its share of the course grade.
  4. Click “Add assignment” for more rows as results come in.
  5. Read your current weighted grade, the letter grade and the total weight entered.
