CGPI to Percentage Calculator for Mumbai University
Mumbai University runs four grading schemes at once and two of them have no conversion formula at all. Pick yours and the page applies the rule that actually governs you, with the circular named.
Convert your grade to a percentage
Converting a single semester? Put your SGPI or SGPA in the same box. Colleges apply the conversion the same way, though the circulars are written about the cumulative figure.
Equivalent percentage
Every other calculation
Percentage back to CGPI
Useful when a form asks for a pointer and all you have is a percentage. This only works for the two schemes that have an equation to reverse.
Approximate index
Reversing a rounded formula cannot be exact. The circular rounds up, so several pointers map to the same percentage and only your marksheet settles which one is yours.
CGPI to CGPA
This is the second most searched conversion for Mumbai University, and the honest answer is that there is nothing to convert.
Your CGPA
Both are the same cumulative figure on the same 10-point scale. The Faculty of Technology and the older choice based schemes call it an Index, NEP 2020 and the Arts, Science and Commerce schemes call it an Average. If a form asks for CGPA and your marksheet says CGPI, write the number as printed.
SGPA for this semester
Enter each course, its credits and the grade point you earned. Course names are optional and only make the working easier to read.
Your SGPA
SGPA is the sum of credit times grade point, divided by the sum of credits, reported to two decimal places. Same arithmetic in every scheme MU runs.
CGPA from your semesters
Enter the SGPA of each completed semester. Add the credits too and the weighting is done properly, which matters when semesters differ in size.
Your CGPA
Leave the credit column empty and this falls back to a plain average of your semesters, which is close but not what the university computes. Engineering semesters in particular are not equal in credits.
Marks to grade
The band boundaries moved when NEP arrived, so the same marks can be two different letters depending on your scheme.
Grade
A mark of 58 is B under NEP and B under CBSGS, but 52 is C under both while 62 is B+ under NEP and A under CBSGS. Check which table your syllabus prints.
Did I pass this course
Under NEP 2020 you must reach 40 percent in the internal and in the semester-end paper separately. Clearing the total is not enough, and this is the rule students are most often caught by.

Result
The 40 to 60 split shown here is what B.Com and B.A. run. Some honours semesters run 50 to 50. Your own syllabus circular prints the split that binds you, so change the totals to match it.
Promotion credits, engineering under NEP
NEP replaced the old heads of passing count with a credit threshold, so the question is no longer how many subjects you failed but how many credits you earned.
Promotion
Circular No. 2026/March/AAMS/C-176/26951, dated 2 March 2026, on the Board of Deans recommendation of 11 February 2026. Semesters I and II carry 45 credits between them, 23 and 22.
Four schemes, four different answers to the same question. This is the whole of it.
Engineering (Faculty of Technology)
Formula
B.E. and B.Tech at MU affiliated engineering colleges.
Percentage = 7.1 × CGPI + 12 when CGPI is below 7, and 7.4 × CGPI + 12 when CGPI is 7 or above, rounded up to the next whole number.
Circular No. Exam/Engg/720 of 2015, dated 30 November 2015
Printed verbatim on the official B.E. transcript, including the instruction to round to the next full integer. The 2026 conversion circular is addressed to Arts, Science, Commerce and Management, so it does not disturb this one.
NEP 2020 (all faculties, newer batches)
Band table
Students admitted under NEP 2020. UG rolled out from 2024-25.
No formula. The syllabus prints a table that puts each CGPA band against a percentage band, so a CGPA of 7.00 to under 8.00 corresponds to 70 to under 80 percent.
Grade table printed in every MU NEP 2020 syllabus circular
Verified identical across four separate MU syllabus circulars in Humanities, Commerce and Management.
CBCS 10-point (choice based, 2016-17 onwards)
Formula
Graduate and post graduate choice based courses from 2016-17, before NEP.
Percentage = 7.25 × CGPI + 11, rounded to the next full integer.
Circular No. Exam/Com/97 of 2018, dated 17 October 2018 Repealed 1 January 2026.
This circular was repealed on 1 January 2026. The formula is kept here because it is the number printed on conversion certificates issued while it was in force.
CBSGS 7-point (credit based semester and grading)
Actual marks
Arts, Science and Commerce UG admitted from 2011-12, before the 10-point scale.
No formula, and there never was one. The percentage is the percentage of the actual marks you obtained.
Circular No. Exam/Com/97 of 2018, paragraph 1
The 7-point index was never designed to convert. Any site that gives you a formula for it is inventing one.
The official grade tables
Both scales still have students sitting under them, so both are here as printed.

Passing, promotion and the other numbers
Thresholds a student has to work out at some point, each with the circular that fixes it.
Passing a course under NEP 2020
The standard of passing is 40 percent, and you must clear the internal and the semester-end paper separately. Clearing one and failing the other is a fail. Scheme of examination printed in every MU NEP 2020 syllabus circular
The internal to external split
It is set per programme, not university wide. B.Com and B.A. run 40 internal to 60 external. Some honours semesters run 50 to 50. Your own syllabus circular prints the split that binds you. MU NEP 2020 syllabus circulars, scheme of examination
Engineering promotion to second year
Semesters I and II carry 45 credits together, 23 then 22. You need 32 of those 45 to move up, which leaves room to carry about 13 credits of backlog. Circular No. 2026/March/AAMS/C-176/26951, dated 2 March 2026
Engineering promotion to third year
You need 76 or more cumulative credits across Semesters I to IV. First year backlogs no longer block you outright, which is the change NEP made to the old R-2019 heads of passing rule. Circular No. 2026/March/AAMS/C-176/26951, dated 2 March 2026
Leaving engineering early with a degree
To exit after first, second or third year you must earn 3 credits of theory and 1 of practical, plus an internship of one month or 160 hours counted as 4 credits. Circular No. AAMS_UGS/ICC/2025-26/69, dated 9 July 2025
Grade gracing under CBSGS
One credit-cum-grade-point is added to the total of credit times grade, never to the credits, and only to lift B to A or A to O. A GPA of 5.95 becomes 6.00 and the grade becomes A. MU FAQ on the Credit Based Semester and Grading System, O.5043 and O.5044
CGPI, CGPA, SGPI and SGPA
CGPI is the Cumulative Grade Performance Index. It is your standing across every semester you have completed, on a 10-point scale, worked out from the credits and grade points of each course you cleared.
The four names are two ideas crossed with two vocabularies. S means one semester, C means everything so far. Index is the word the Faculty of Technology and the older choice based schemes use, Average is the word NEP 2020 and the Arts, Science and Commerce schemes use.

So CGPI and CGPA are the same number. There is no conversion between them and no site can give you one. What genuinely differs, and what this page exists to sort out, is the percentage rule attached to each scheme.
Questions students ask
It depends on which scheme you sit under, and for two of the four there is no formula at all. Engineering uses 7.1 x CGPI + 12 below a CGPI of 7 and 7.4 x CGPI + 12 at 7 and above, rounded up, under Circular Exam/Engg/720 of 2015. The 10-point CBCS scheme used 7.25 x CGPI + 11 under Circular Exam/Com/97 of 2018, but that circular was repealed on 1 January 2026. NEP 2020 publishes a band table rather than an equation. The 7-point CBSGS scheme has always been converted from actual marks.
Yes. A circular dated 1 January 2026 repealed the 2018 and 2019 conversion circulars. For Arts, Science, Commerce and Management the university now says the percentage must be worked out from the actual marks across all semesters, that the college does the conversion, and that a certificate is issued only if you ask for one. There is no longer a formula for these faculties.
For engineering, yes, it is the figure the 2015 circular prescribes. For the 10-point CBCS scheme it is the figure that was official until 1 January 2026 and is the one printed on certificates issued before then. For NEP and for the 7-point scheme it is an indication only, because the university prescribes a band or actual marks instead. Whenever a form, an employer or a university abroad needs a percentage on paper, ask your college for the conversion certificate.
CGPI is the Cumulative Grade Performance Index. It is your overall grade performance across the semesters you have completed, on a 10-point scale, worked out from the credits and grade points of every course you have cleared.
On a Mumbai University marksheet they are the same number on the same 10-point scale, under two names. Index is the word the Faculty of Technology and the older choice based schemes use, Average is the word NEP 2020 and the Arts, Science and Commerce schemes use. There is nothing to convert between them. What genuinely differs is the percentage rule attached to each scheme.
SGPI is one semester on its own. CGPI is every semester you have completed so far, weighted by credits. A strong semester moves your SGPI a long way and your CGPI a little.
Multiply each course credit by the grade point you earned in that course, add those products, then divide by the total credits for the semester. The university writes it as the sum of credit times grade divided by the sum of credits, and the result is reported to two decimal places.
Under NEP 2020 the standard of passing is 40 percent and you must reach it separately in the internal assessment and in the semester-end paper. Passing on the total while failing one half is still a fail. Under the older 7-point scheme the minimum passing grade is E, which is 40 to 44.99 marks and 2 grade points.
Thirty-two of the 45 credits that Semesters I and II carry between them, under the circular of 2 March 2026. That leaves about 13 credits of backlog you can carry. For third year you need 76 or more cumulative credits from Semesters I to IV.
Most of them apply one formula to every Mumbai University student, and several publish a formula belonging to a different university altogether. Mumbai runs four schemes side by side, two of which have no formula, so a single answer for everybody is wrong for most people. Every rule on this page names the circular it comes from so you can check it.
