CGPA Calculator Formula & Calculation

Percentage = CGPA × Multiplier + Offset (multiplier/offset depends on university convention)

Different Indian universities publish different official conversion formulas: Generic/most universities and job applications use ×10 (no offset); Anna University uses ×10 − 7.5; VTU uses ×10; CBSE and Delhi University use ×9.5. A custom mode lets you enter any multiplier and offset if your institution uses a different convention.

Example: CGPA = 8.5 under the CBSE convention (×9.5) → Percentage = 8.5 × 9.5 = 80.75%. The same 8.5 CGPA under Anna University's convention (×10 − 7.5) → 8.5 × 10 − 7.5 = 77.5% — nearly 3.25 percentage points lower for the identical CGPA.

Key Factors That Affect Your Result

  1. University-specific formula — There is no single universal CGPA-to-percentage formula in India; always confirm your institution's officially published formula (on the marksheet or university website) before using a converted percentage for an application, since the wrong formula can misrepresent your score by several points.
  2. Grade point scale — This assumes a 10-point CGPA scale (the most common in India); if your institution uses a 4-point scale, the conversion logic is entirely different and this calculator's presets would not apply.
  3. Use case caveat — Many employers and foreign universities now accept CGPA directly without conversion — check whether a percentage conversion is actually required before relying on one for admissions or job applications.
