CGPA to Percentage Converter — University-aware

No. There is no universal CGPA-to-percentage formula in India. Each university decides its own conversion rule, which is published in the academic regulations. Some use a simple 10× multiplier, others subtract a fixed offset (0.5 or 0.75), and a few (like Mumbai University) use a linear formula like 7.1 × CGPA + 11. Always check the conversion certificate issued by your university for an authoritative figure.

Anna University historically used % = CGPA × 10 − 7.5 for the older 10-point grading scheme. The newer regulations (R-2017 and later) shifted to % = (CGPA − 0.5) × 10. For a CGPA of 8.0, that's 72.5% under the old formula vs 75% under the newer one. Check your transcript or the AU website for which formula applies to your batch — this calculator defaults to the newer one.

Switch the calculator to '% → CGPA' mode. The tool applies the inverse of the chosen formula. For example, with VTU's % = (CGPA − 0.75) × 10, the inverse is CGPA = (% ÷ 10) + 0.75. So 80% maps to a CGPA of 8.75. This is useful when you have a percentage transcript and need to fill a CGPA field on an application form.

Because each university's grading is calibrated to its own grade boundaries. A 7.5 CGPA at VTU (= 67.5%) reflects the grade distribution at VTU; the same 7.5 CGPA at Anna University maps to 70% under the newer formula and 67.5% under the old one. Universities publish their formulas to make the conversion deterministic for placement and admission committees.

The widely used Indian academic grading is: Distinction at 75% and above, First Division (or First Class) at 60% and above, Second Division at 50% and above, and Third Division at 40% and above. Anything below 40% is typically considered fail. These boundaries are not legally fixed — some universities use 65% or 70% as the First Division cut-off — but the values above are the most common.

Use the formula your university officially publishes — it appears in the academic regulations or on the back of your transcript. Many universities also issue a 'CGPA conversion certificate' on request, which most placement committees and foreign universities will accept as authoritative. Do not use the generic 10× formula unless your university explicitly mandates it.

It works for any institution that uses a 10-point CGPA system with one of the formulas listed. For US universities (4.0 GPA scale), Australian (7.0 scale), or European ECTS systems, you need a different conversion — those are not 10-point systems. Use this calculator only for Indian 10-point CGPA conversions.
