CGPA to Percentage Calculator for Indian Universities

Degree marksheets increasingly print only a CGPA, while SSC, UPSC, bank and state PSC forms still ask for a percentage. The conversion rule depends on which university issued the degree, and the same CGPA can translate to figures several points apart. This calculator keeps the common formulas in one place, applies the one you choose, and prints the working so you can match it against your conversion certificate.

There are four modes. CGPA to percentage and Percentage to CGPA handle the two directions a form might ask for. CGPA from grades takes each subject's credits and letter grade on the UGC 10-point or VTU S-grade scale (or typed grade points) and returns the credit-weighted average. CGPA from SGPA combines semester results, weighted by credits, for up to 12 semesters.

Every university formula here is as notified by that university; confirm with your grade card before writing a figure on an application.

1. Choose a mode in the left panel: CGPA to percentage, Percentage to CGPA, CGPA from grades or CGPA from SGPA.
2. In either conversion mode, pick the formula chip (CBSE, × 10, VTU, AKTU / JNTU, Mumbai Univ. or Custom); for Custom, type your university's multiplier and deduction.
3. Enter your CGPA (0 to 10) or your percentage (0 to 100); the result appears as soon as the value is within range.
4. In CGPA from grades, select the grade scale, then enter credits and the grade for each subject, adding rows with Add subject.
5. In CGPA from SGPA, type each semester's SGPA and its credits, adding semesters as needed.
6. Read the headline figure, the working lines beneath it, and the Class, As percentage and CGPA cards.

Each conversion is a straight-line formula, and Percentage to CGPA simply inverts the chosen one. The two grade-based modes compute a credit-weighted average, which is how universities arrive at the CGPA on the final marksheet. A row with zero credits is skipped, and an SGPA outside 0 to 10 is ignored.

• CBSE: percentage = CGPA × 9.5; reverse is percentage ÷ 9.5. As notified by CBSE for grade-based Class 10 results; confirm with your grade card.
• × 10: percentage = CGPA × 10; reverse is percentage ÷ 10. Used by Anna University and many state universities, as notified by that university; confirm with your grade card.
• VTU: percentage = (CGPA - 0.75) × 10; reverse is percentage ÷ 10 + 0.75. As notified by VTU; confirm with your grade card.
• AKTU / JNTU: percentage = (CGPA - 0.5) × 10; reverse is percentage ÷ 10 + 0.5. As notified by those universities; confirm with your grade card.
• Mumbai Univ.: percentage = 7.1 × CGPA + 11, for CGPA of 7 and above; the tool warns below 7 because a different band applies there. As notified by Mumbai University; confirm with your grade card.
• Custom: percentage = CGPA × multiplier - deduction; reverse is (percentage + deduction) ÷ multiplier.
• CGPA from grades: sum of (credits × grade points) ÷ sum of credits. UGC scale: O 10, A+ 9, A 8, B+ 7, B 6, C 5, P 4, F 0. VTU S-grade scale: S 10, A 9, B 8, C 7, D 6, E 5, F 0.
• CGPA from SGPA: sum of (SGPA × semester credits) ÷ total credits.

Hypothetical: a graduate has a CGPA of 8.6 and needs a percentage for a form. The table shows what each formula chip returns. The spread runs from 72.06% to 86.00% for the same grade card, so picking the formula your university notified matters more than the arithmetic.

A grade-sheet example, also hypothetical, on the UGC scale with the tool's default four rows: 4 credits at A (8 points) = 32, 4 credits at A+ (9) = 36, 3 credits at B+ (7) = 21, and 3 credits at A (8) = 24. That is 113 grade points over 14 credits, so CGPA = 113 ÷ 14 = 8.07. The Class card reads First class, and the As percentage card shows 8.07 × 9.5 = 76.68% using the CBSE factor, since no university formula is selected in this mode.

The headline is the converted figure to two decimals. The grey line names the formula used, for example 8.60 CGPA by VTU formula, so a screenshot carries its own basis, and the working lines list each input or each subject's credits × points.

Class follows a common 10-point convention: 8.5 and above First class with distinction, 6.5 to 8.49 First class, 5.5 to 6.49 Second class, 4 to 5.49 Pass class, below 4 shown as below pass. Universities define their own boundaries, often on percentage, so take the card as a rough guide. As percentage repeats the conversion, by × 9.5 in the grade and semester modes. A warning appears when a value is out of range or the Mumbai chip is used below 7.

• Applying the CBSE 9.5 factor to a university degree because it is the formula everyone remembers from school.
• Choosing the Mumbai chip with a CGPA below 7. The 7.1 × CGPA + 11 line is for 7 and above; the lower bands are on the grade card.
• Reading the letter A as the same points on both scales. A is 8 on the UGC scale and 9 on the VTU S-grade scale; pick the scale printed on your marksheet.
• Treating every semester as equal credits when the final year carries a project with more. Enter the actual credits so the weighting is right.

The arithmetic matches the formulas listed above exactly. The uncertainty is in which formula applies to you. There is no national conversion standard; each university notifies its own, some change it between batches, and some issue a conversion certificate instead. Recruiters such as SSC and UPSC generally accept the university's notified rule and may specify a default when none exists, so read the eligibility clause. The tool accepts only the 10-point scale, and the grade modes compute from the points you enter, never from raw marks. Nothing is uploaded; the calculation runs in your browser.

The number that counts at document verification is the one on the official conversion certificate or printed on the marksheet; use this page to check it.
