📊 Percentage Calculator
Convert any marks-out-of-total into a percentage, and see the equivalent letter grade under both the Indian and US grading conventions.
Percentage = (Marks Obtained ÷ Total Marks) × 100
The same formula works whether you're converting a single subject's marks or an aggregate across an entire exam — just make sure both numbers use the same total scale.
Frequently Asked Questions
How is percentage different from CGPA?
Percentage is a direct ratio of marks to total marks. CGPA is a weighted grade-point average on a 10-point (or other) scale — converting between them requires a multiplier specific to your university, not a fixed universal formula.
What's considered a good percentage in India?
Conventions vary by board and stream, but broadly: 90%+ is often labelled outstanding/distinction, 75-89% first class, 60-74% second class, and below that varies by institution's pass criteria.
Can I use this for aggregate marks across multiple subjects?
Yes — add up marks obtained across all subjects for the numerator, and the sum of maximum marks for each subject as the total.
