About AnaCGPA
Free, accurate academic calculators for Indian and international students - built by a student who actually needed them.
Who built AnaCGPA?
My name is Anas Alam. I am an engineering student who got frustrated with CGPA calculators that returned wrong answers - using incorrect formulas, missing university-specific methods, or showing generic numbers without explaining how they arrived at the result.
AnaCGPA started as a personal project to build the tool I actually needed: one that shows the formula, explains which university or board that formula belongs to, and gives a result you can confidently use on official applications and transcripts.
You can verify my background on LinkedIn.

How we verify our formulas
Every conversion formula is sourced from official documents. We do not use generic multipliers without attribution:
| Institution | Formula | Source |
|---|---|---|
| CBSE (Class 10 and 12) | Percentage = CGPA x 9.5 | CBSE Official Circular, Jan 2010 |
| AICTE / VTU | Percentage = (CGPA - 0.75) x 10 | Adopted across AICTE-approved colleges |
| Anna University | Percentage = CGPA x 10 | Anna University Regulation 2017/2021 |
| Mumbai University (CBCS) | Percentage = (7.1 x CGPA) + 11 | Mumbai University Engineering CBCS |
| US 4.0 Scale | Percentage = (GPA / 4) x 100 | Standard US grading conversion |
If your university uses a different method, always cross-check with your official marksheet or the Controller of Examinations office.
Privacy - no calculator data is collected
All calculations happen entirely in your browser. AnaCGPA does not send your grades, marks, or any calculator inputs to any server. The only analytics collected are standard page-view events via Google Analytics - no personal academic data is ever transmitted.
