Use this grade calculator to estimate percentage and letter grade from obtained marks and total marks. It is useful for quick academic checks, rough result review and simple planning before official results are confirmed.
This result is based on the grading scale shown below, not on a universal academic standard.
A grade calculator helps convert marks into percentage and a corresponding letter grade. This is useful when students want a quick idea of their likely result without manually calculating percentages and checking grade ranges themselves.
It can be used for a rough academic check after tests, assignments or exams, especially when an institution follows a simple percentage-based grading pattern.
The calculator divides obtained marks by total marks, converts the result to a percentage, and then maps that percentage to a grade based on the grading scale used on this page.
This is a common sample scale for quick estimation. Your institution may use different cutoffs, letters, grade points or conversion policies.
Suppose a student scores 72 marks out of 100.
Percentage = (72 ÷ 100) × 100 = 72%
Based on the grading scale used here, a percentage of 72% falls in grade B.
Grade systems vary by school, board, college and university. Some institutions use percentage bands, while others use internal moderation, subject weighting, grade points, curves or fixed conversion tables.
That means this tool is best used for quick estimation and planning. For official grade interpretation, always follow your institution’s published grading policy.
