What Is a Quiz Grade Calculator?
A Quiz Grade Calculator is a simple tool that converts the number of correct answers on a quiz into a percentage score and letter grade. It can also show how many answers were incorrect and whether the score meets a selected passing grade.
Instead of manually dividing correct answers by total questions, you can enter both values and receive the complete result instantly.

How Does the Quiz Grade Calculator Work?
The calculator divides the number of correct answers by the total number of quiz questions. It then multiplies that value by 100 to convert the result into a percentage.
Quiz Grade Example
Suppose your quiz contains 20 questions.
You answer 17 questions correctly.
The calculation is:
(17 ÷ 20) × 100 = 85%
Using the default grading scale, an 85% quiz score corresponds to a B.

| 80% – 89.99% | B |

How Are Wrong Answers Calculated?
When each quiz question has the same value, incorrect answers are calculated by subtracting correct answers from the total number of questions.
Quiz Percentage vs. Letter Grade
Your quiz percentage is the mathematical percentage of questions answered correctly. A letter grade converts that percentage into a category such as A, B, C, D or F.
The percentage itself comes directly from your quiz result, while the letter grade depends on the grading scale used by your teacher or school.
