Formula:
Percentage = (Score Earned ÷ Total Score) × 100Understanding Grade Percentages
Grade percentages are the standard way to measure academic performance. They translate raw scores (points earned) into a standardized 0-100 scale, making it easy to compare results across different assignments and tests.
Most schools use a grading scale where 90-100% is an A, 80-89% is a B, etc. Knowing your exact percentage helps you understand exactly where you stand and how close you are to the next letter grade.

Frequently Asked Questions
How do I calculate my test percentage?
Divide your earned score by the total possible score, then multiply the result by 100.
Is 18/20 the same as 90%?
Yes. 18 divided by 20 is 0.9, multiplied by 100 equals 90%.
Can percentages exceed 100%?
Yes, if you earned extra credit points that make your score higher than the standard total (e.g., 55/50 = 110%).
What if total score changes?
The percentage changes inversely. If the total points increase while your earned points stay the same, your percentage decreases.
Are decimals allowed?
Yes, you can enter decimal scores (like 7.5) and the calculator will produce an accurate percentage.
