Use this free online percentage to CGPA calculator to convert your percentage of marks into an equivalent CGPA (out of 10), using the standard CBSE divisor.
This tool reverses the CBSE rule of Percentage = CGPA × 9.5, so it divides instead: CGPA = Percentage ÷ Divisor. With the default divisor of 9.5, 82% becomes 82 ÷ 9.5 = 8.63.
Because 95 ÷ 9.5 is exactly 10, any percentage of 95 or above gives the maximum CGPA of 10.00. The result is rounded to two decimal places and never shown above 10.
Where a form gives you the choice, it is usually better to report your original percentage and let the institution convert it with its own rules. An estimated CGPA is a reasonable answer for informal comparison but is not an official grade.
The middle column is what this calculator shows with the default divisor. The last column reverses the AICTE-recommended formula, Percentage = (CGPA − 0.75) × 10, which some engineering universities follow and which gives a higher CGPA for the same marks.
| Percentage | Percentage ÷ 9.5 | Percentage ÷ 10 + 0.75 |
|---|---|---|
| 95% | 10.00 | 10.00 |
| 90% | 9.47 | 9.75 |
| 85% | 8.95 | 9.25 |
| 80% | 8.42 | 8.75 |
| 75% | 7.89 | 8.25 |
| 70% | 7.37 | 7.75 |
| 65% | 6.84 | 7.25 |
| 60% | 6.32 | 6.75 |
| 50% | 5.26 | 5.75 |
| 40% | 4.21 | 4.75 |
Under the AICTE formula, 92.5% already corresponds to a CGPA of 10, so 95% is shown capped at 10.00 in both columns.
Real CGPAs are built subject by subject: each subject is placed in a grade band, converted to a grade point, and the points are averaged, often weighted by credits. Dividing an overall percentage by 9.5 skips those steps, so a student with uneven marks across subjects may get a noticeably different CGPA from the official one.
If your institution publishes its own percentage-to-grade table, use that table. If it publishes a CGPA-to-percentage formula that is a plain multiplication, enter that multiplier in the "Divisor" box to reverse it.
