What is Percentage?
Percentage tells you what fraction of total marks you scored, scaled to 100. It's the most common way Indian schools, colleges and employers report academic performance.
Formula
Basic: Percentage = (Marks obtained / Total marks) × 100 Marks needed for target T%: Required = (T / 100) × (already-out-of + remaining) − scored
How to use this calculator
