Most IIMs use the 10x factor for CGPA to percentage conversion (e.g., 9.
2 CGPA = 92%) unless your UG university provides a specific conversion formula. At IIM Ahmedabad (Rs 27.5L fees, Rs 35.
22 LPA avg, 99%+ CAT cutoff), the conversion is exactly 10x CGPA unless your transcript explicitly provides a conversion formula. For IITs and specific universities with 10-point CGPA scales, the formula is often (CGPA - 0.5) × 10, so a 9.
0 CGPA = 85%. For engineering with 10-point scale and average grade inflation, most candidates land at 80-85% via formulae. This matters because a 9.
2 CGPA might be 80.75% via 8.5 × 9.
5 formula (IIT-style) but 92% via 10x (generic scale) - the difference can mean 0 points vs 10 points at IIM. Practical advice: check your UG transcript carefully and use the formula your college officially provides. Don't self-convert favourably - IIMs verify against transcripts.
BCom students with 75% equivalent need to claim 75% (not 8.0 CGPA self-converted to 80%). For the student with 9.
2 CGPA claiming 87% actual percentage, IIMs will honour the lower number unless transcript says otherwise. Check with admissions office if conversion is ambiguous - different IIMs may apply different formulae. The safest practice: report the lower of the two numbers when uncertain.
This mostly applies to UG; 10th and 12th boards give clear percentages in most cases. Check your eligibility at collvera.
