Convert marks into a percentage and determine the corresponding letter grade using your selected grading scale.
A grade calculator converts the marks you earned into a percentage and then matches that percentage against the boundaries of a selected grading system.
For example, if you score 75 marks out of 100, your percentage is 75%. The letter grade depends on the grading scale being used by your school or institution.
Enter the marks you obtained and the total possible marks. Then select the grading system you want to use.
Enter the number of marks you obtained in the assessment, examination, assignment or test.
Enter the maximum number of marks available for the assessment.
Select the grading scale you want to use. If your school has its own grading boundaries, use those official boundaries when determining an official result.

The scale below is the one currently selected in the calculator.
Suppose a student scores 75 marks out of a possible 100 marks.
The student's percentage is therefore 75%. The letter grade depends on the grading scale being applied. Under the Nigerian school scale provided in this calculator, 75% falls within the A range.
A percentage expresses your score as a proportion of the total marks available. This makes it easier to compare results from assessments that have different maximum scores.
For example, scoring 45 out of 50 and scoring 90 out of 100 represent the same percentage: 90%.
The percentage calculation itself is straightforward, but the letter grade assigned to that percentage depends on the grading scale used by the relevant institution.
