What Is a Grade Calculator?

A grade calculator is a simple academic tool that converts obtained marks into a percentage and letter grade. It helps students and teachers understand test scores, assignment results, project marks, and exam performance quickly.

Instead of calculating marks manually, you can enter the total possible marks and the marks you earned. The calculator then shows your percentage, grade, lost marks, and pass/fail status.

Grade calculation is part of academic assessment. You can also learn more about educational assessment and how scores are used to evaluate learning.

How to Calculate Grade Percentage

Grade percentage is calculated by dividing obtained marks by total marks and multiplying the result by 100. This gives your score as a percentage out of 100.

Grade Percentage = (Obtained Marks ÷ Total Marks) × 100

Example: If you got 85 marks out of 100, your grade percentage is 85 ÷ 100 × 100 = 85%.

  • Total marks are the maximum possible marks.
  • Obtained marks are the marks you earned.
  • Percentage shows your score out of 100.
  • Letter grade is based on the percentage score.

This calculator uses a common grading scale. Your school, college, or teacher may use a different grade scale, so always follow your official grading policy when needed.

Type Meaning Example
Obtained Marks The marks you earned. 42 out of 50
Total Marks The maximum possible marks. 50 total marks
Percentage Your score converted out of 100. 84%
