Easy Test Grade Calculator

Use this easy grader to calculate a test score in seconds. Enter the total number of questions and the number answered correctly to see the percentage, incorrect answers and an estimated letter grade.

It is useful for teachers checking quizzes and worksheets, and for students who want to understand a score before results are released.

How to use the Easy Grader

  1. Enter the total number of questions on the test.
  2. Enter the number of correct answers.
  3. Calculate the result.
  4. Review the percentage score, number wrong and letter grade.
  5. Use the grading chart if you need to check several scores quickly.

For example, if a student answers 18 questions correctly out of 20, the result is 90%. The student got 2 questions wrong.

How test percentages are calculated

The calculator divides the number of correct answers by the total number of questions, then multiplies the result by 100.

For example:

18 correct answers ÷ 20 total questions × 100 = 90%

Letter grades can vary between schools. The grade shown by this tool is a general guide; always use your school or institution’s official grading policy where needed.
