This quiz grade calculator turns correct or wrong answers into a percentage. Enter any two of total questions, correct answers, and wrong answers, or switch to points mode for partial credit and mixed point values.
Use counts for equal questions and points for everything else
The fastest route depends on what the assessment records. Counts are simple; points preserve partial credit and different question values.
In Question count, fill two of Total, Correct, and Wrong. Leave the value you want to find blank.
If one question is worth 5 or an answer earned half credit, use Points earned and possible.
A percentage is objective; a letter grade depends on the teacher's cutoffs and is intentionally not guessed.
Example: 17 correct out of 25
- Enter 25 total questions and 17 correct answers.
- The linked field fills 8 wrong answers, and the engine calculates
17 ÷ 25 × 100 = 68%. - The result is 68.00%.
Why the nearby-score chart is useful
For equal-value questions, every additional wrong answer changes the percentage by 100 ÷ total questions points. The chart shows nearby correct/wrong combinations so a teacher can grade a stack without recalculating each paper.
How the target mode rounds
Suppose a target requires 31.2 correct answers. Because a quiz cannot award 0.2 of an equal-value question in count mode, the engine rounds up to 32 correct answers. That guarantees the resulting percentage reaches the target instead of falling just short.
Frequently asked questions
How do I turn wrong answers into a quiz percentage?
Enter total questions and wrong answers, leaving Correct answers blank. The calculator subtracts wrong from total, then divides correct answers by total questions and multiplies by 100.
How do I calculate a test grade from points earned?
Choose Points earned and possible, enter both totals, and divide earned by possible times 100. This mode supports partial credit and questions with different point values.
How does extra credit affect my percentage?
In points mode, earned points may exceed possible points and produce a result above 100%. Whether that score is capped or carried into a course grade depends on the instructor's policy.
