What this calculator helps you figure out

You can use it to calculate:

It is designed to remove guesswork and provide a reliable grade, even when the total points are unusual or questions carry equal weight.

How the grade is calculated

Here is the simple formula used to determine the score:

Percentage = (Number Correct ÷ Total Questions) × 100

A: 90–100%:
B: 80–89%:
C: 70–79%:
D: 60–69%:
F: Below 60%:

Many students and teachers use this formula daily, and it works across all subjects and grading systems.

If your school or institution uses letter grades, the calculator can apply the standard scale often used internationally:

If your environment uses a different grading scale, the percentage result still gives you the detail you need.
