Percentage

79.8%

8.4 × 9.5 = 79.8%

How we got this

Formula: CGPA × 9.5.
Put in 8.4: 8.4 × 9.5.
Result: 79.8%. Your marksheet or university rule overrides this.

Which CGPA formula is yours

A CGPA is a weighted average of grade points, and a grade point covers a band of marks, so no formula can give back your exact percentage. Each board publishes an approximation so that employers and colleges can compare. Use the one your own board or university states, and quote the percentage printed on your certificate if there is one.

CBSE's 9.5 comes from the board looking at the average marks of the top 10% of students in each subject, which came out at about 95 for a grade point of 10. Most universities now simply multiply by 10. MAKAUT, JNTUK R20 and VTU's 2015 to 2018 schemes subtract 0.75 before multiplying by 10, and JNTUH, GTU and BPUT subtract 0.5. The table below lists 21 rules with the document each comes from. Mumbai University's long-used 7.1 × CGPI + 11 was repealed from 1 January 2026; it only matters for older transcripts.

If you are applying abroad, convert to the 4.0 GPA scale or, for Germany, use the Bavarian formula. For a single exam's marks, the percentage calculator gives marks percentage directly, and the GPA calculator averages grades by credits.
