Turn points earned into a percentage and letter grade instantly. Enter your score on any test, quiz, or assignment using this tool’s illustrative plus/minus scale.
Test Grade Calculator
Formula
Percentage = (Points Earned / Points Possible) × 100
Grading scales vary by institution and course, so use the letter grade shown here as a general reference only. Percentages display two decimal places; letter grades use the unrounded score. Extra-credit totals above 100% are allowed and show zero points missed.
Sample Grade Scale
Quick Examples
Grading Notes
Not every school uses plus/minus grading.
Some instructors curve scores before assigning a grade.
Always confirm the exact scale in your syllabus.
How to Use
- Enter the number of points you earned
- Enter the total points the test or assignment was worth
- View your percentage score, letter grade, and points missed instantly
- Compare your result against the grade scale reference to see how close you are to the next grade
Important Notes
- Grading scales vary by institution and even by course, so treat the letter grade shown here as a general reference
- Plus/minus grading (A-, B+, etc.) isn't universal — some schools only use whole letter grades
- Always check your syllabus or instructor's stated grading scale for the scale that actually counts toward your grade
- This tool does not account for curves or category weights. Enter points after any approved adjustments; scores above the points possible are shown above 100%, not capped

The condition that changes the answer.
Points possible must be positive. Extra-credit results above 100% need an explicit school policy rather than an assumed letter grade.
