How the test grade calculator works

This tool divides points earned by points possible, then maps the percent to a common US letter grade. Use it for one quiz, test, or assignment. It is not a class average, not a weighted grade calculator, and not a final exam calculator.

How to use the calculator

  1. Enter points earned, such as 18.
  2. Enter points possible, such as 20.
  3. Calculate to see the percent and letter.
  4. Use the letter grade page if you already have a percent, or grade average if you have several scores.

Worked example

18 out of 20 is 90.0%, which is A- (3.7) on this scale. 40 out of 50 is 80.0%, which is B- (2.7).

Understanding your result

The percent is earned divided by possible, shown to one decimal. The letter uses the same common US scale as the letter grade calculator. Your syllabus can differ.

Frequently asked questions

18 ÷ 20 = 90.0%. On this scale that is A- (3.7 points).

40 ÷ 50 = 80.0%, which is B- (2.7). Enter any earned and possible totals the same way.

No. This grades one assignment. Use the grade average calculator for equal-weight scores, or the weighted grade calculator for syllabus weights.

No. After you know this assignment grade, use the final grade calculator for the exam score you still need.
