- Internal % = 18.00 ÷ 20.00 × 100 = 90.00%
- External % = 62.00 ÷ 80.00 × 100 = 77.50%
- Weighted = (90.00% × 40%) + (77.50% × 60%) = 82.50%

How the weighted percentage is calculated
Each block explains one part of how this works and how to read the result.
Two percentages, blended by your college’s own weightage
Internal % and external % are each calculated from your marks and maximum. The final result blends them using the weightage your own college publishes (commonly 40:60 or 25:75, but this varies — check your own scheme of examination rather than assuming). We never assert a universal weightage; you enter yours.
Frequently asked questions
What weightage should I use?
Check your college’s scheme of examination or ask your department — weightage varies by institution and even by subject. This tool does not assume one for you.
Does this apply to every subject?
Only where your course uses a two-part internal+external split. Purely-external or purely-internal subjects don’t need this tool.
Can weightage be something other than whole numbers like 40/60?
Yes — enter any split that sums to 100, e.g. 30/70 or 50/50.
Is this the same as CGPA conversion?
No — this gives a per-subject percentage from two mark components. Use the CGPA to Percentage Calculator separately for grade-point conversion.
