To calculate a grade percentage, divide the points earned by the total possible points and multiply by 100. Formula: (Points / Total) * 100. For example, if you score 18 out of 20, your grade is (18/20) * 100 = 90%.

The quickest way to calculate your assignment score.

Formula

Grade (%) = (Score / Max Score) * 100. Letter grade is mapped based on local scaling (e.g., 90%+ = A).

How It Works

Look at your graded assignment to find your score.
Identify the maximum possible points for the test.
Enter both numbers to see your percentage instantly.
Review the letter grade based on the standard 10-point scale.

Formula:

Grade = (Your Points / Total Points) * 100

Examples

What is a 45 out of 50 as a percentage?

Result: 90%. This is typically an A or high B.

What is 32 out of 40?

Result: 80%. This is a B.

Frequently Asked Questions

Does this calculator include "Curves"?

No, this is a raw score calculator. Curved grades are determined by your instructor based on the entire class distribution.

What is a "Weighted" grade?

A weighted grade counts different assignments differently (e.g., a Final is 50% of your grade). Use our Weighted Grade Calculator for that.

Is 89.5% rounded up to an A?

Most instructors round up from .5, but university policies vary. Check your syllabus!

Key facts

Percentage grading provides a standardized metric for comparing academic performance across different test lengths. A "Curved" grade adjusts raw scores based on class performance distribution. Standard scales: 90-100 (A), 80-89 (B), 70-79 (C), 60-69 (D). Accuracy improves when rounding to two decimal places for edge cases (e.g., 89.45%).

Trend & Behavior Analysis

Missing a single point on a short test (e.g., 10 questions) has a much larger impact (10%) than on a long test (e.g., 100 questions, 1%). Consistent performance on long-form assessments typically stabilizes a student's overall GPA.
