The Grade Calculator converts a raw score (points earned out of points possible) into a percentage and a letter grade. It is meant for a single assignment, quiz, or exam — enter the points you scored and the points it was worth, and it does the division and grade lookup for you. It uses one fixed, general-purpose letter-grade scale rather than any specific school's grading policy.
The core calculation.
Percentage = (Points Earned ÷ Points Possible) × 100A fixed 10-point scale with no +/- grades.
90%+ = A · 80–89% = B · 70–79% = C · 60–69% = D · below 60% = FPercentage = (92 ÷ 100) × 100 = 92%Percentage = (76 ÷ 100) × 100 = 76%Percentage = (27 ÷ 50) × 100 = 54%- This uses a fixed 10-point US letter scale: 90%+ = A, 80–89% = B, 70–79% = C, 60–69% = D, below 60% = F. There are no +/- grades and no custom cutoffs.
- Points Possible must be greater than zero; a zero, blank, or invalid value returns no result.
- The percentage is Points Earned ÷ Points Possible × 100, rounded to two decimals for display.
- Many schools use different letter-grade cutoffs (for example 93%+ for an A). Check your syllabus if your institution's scale differs.
- This calculates one assignment or exam at a time. To combine several assignments into a course average, use the GPA Calculator or add the points yourself first.
How is my grade percentage calculated?
Percentage = (Points Earned ÷ Points Possible) × 100.
What letter-grade scale does this use?
A fixed scale: 90%+ = A, 80–89% = B, 70–79% = C, 60–69% = D, below 60% = F. It does not support +/- grades or custom cutoffs.
Can I use this for a course average instead of one assignment?
Yes, if you enter your total points earned and total points possible across all assignments. For a credit-weighted course average, use the GPA Calculator instead.
Why does the calculator show no result?
Points Possible must be a number greater than zero. A blank, zero, or invalid entry returns no result.
Does this match my school's official grade?
Only if your school uses the exact same percentage-to-letter cutoffs. Many schools use different scales, so check your syllabus.
