SGPA Calculator

About the SGPA Calculator

Your SGPA (semester grade point average) is the credit-weighted average of the grade points you earned in a semester: multiply each course’s credits by its grade point, add the products — your credit points — and divide by the total credits. This is the formula in the UGC’s Choice Based Credit System guidelines, and the calculator shows every step.

Enter grades as letters (O, A+, A …), as grade points, or as marks; marks are converted with the grade table you pick. The UGC 10-point table is the default; the JNTUH (R22 and R25), Anna University (R2021 and R2025), AKTU and VTU (2021, 2022 and 2025 schemes) tables are included with their marks ranges, each linked to the regulation it comes from, and a custom table covers any other university. Failed courses (backlogs) are flagged, and you can count them as 0 or leave them out, as your university does.

How SGPA is calculated

SGPA = Σ(Ci × Gi) ÷ Σ Ci, where Ci is the credits of course i and Gi its grade point. Credits × grade point is the course’s credit points. The UGC guidelines round the SGPA to two decimal places; so does this calculator (half up — 7.235 becomes 7.24).

The UGC 10-point letter grades are O (Outstanding) 10, A+ (Excellent) 9, A (Very good) 8, B+ (Good) 7, B (Above average) 6, C (Average) 5, P (Pass) 4, F (Fail) 0 and Ab (Absent) 0. UGC leaves the marks needed for each grade, and the pass mark, to each university — so to convert marks you need your university’s table.

University tables included

• JNTUH B.Tech. R22 and R25: O 90+, A+ 80–89, A 70–79, B+ 60–69, B 50–59, C 40–49 (pass), F below 40. A pass also needs at least 35% in the semester-end exam and 40% overall; JNTUH prints no SGPA for a semester until every course in it is passed.
• Anna University R2021 (affiliated colleges): O 91–100, A+ 81–90, A 71–80, B+ 61–70, B 56–60, C 50–55, U below 50; SA and WD count 0. U grades are left out of the GPA. Theory courses with more than 30 passed students are graded relatively, so the marks ranges apply to absolute grading only.
• Anna University R2025 (affiliated colleges): S 91–100 (10), A+ 81–90 (9), A 71–80 (8), B+ 66–70 (7), B 61–65 (6.5), C+ 56–60 (6), C 50–55 (5), U below 50.
• AKTU B.Tech. (Ordinance 2018-19, revised): A+ 90+ (10), A 80–89 (9), B+ 70–79 (8), B 60–69 (7), C 50–59 (6), D 45–49 (5), E 40–44 (4), F below 40. To be declared pass in the yearly result you need E or above in every subject and an SGPA of at least 5.0 in each semester.
• VTU B.E./B.Tech. (2021, 2022 and 2025 schemes): O 90–100 (10), A+ 80–89 (9), A 70–79 (8), B+ 60–69 (7), B 55–59 (6), C 50–54 (5), P 40–49 (4), F below 40 (0); AB (absent) counts 0. A pass needs at least 40% of the CIE marks to sit the SEE, 35% in the SEE and 40% overall, and VTU declares a semester’s SGPA once every course in it is passed.

Marks are compared with each grade’s lowest mark, so 89.5 is still an A+ on the JNTUH table. If your university rounds marks first, enter the rounded marks.

Failed courses and backlogs

The UGC formula counts every course taken, so an F adds its credits with 0 grade points and pulls the SGPA down — JNTUH, AKTU and VTU word it the same way. Anna University’s R2021 regulations instead work out the GPA over the courses cleared, leaving U grades out. The calculator follows the table you pick, lets you switch, and shows the other figure as well. Either way the course stays a backlog until you pass it.

Converting to a percentage

Universities publish their own conversion, so use the one in your regulations. For example, JNTUH R22 gives % = (CGPA − 0.5) × 10 (clause 11.2), Anna University prints % = CGPA × 10 on the consolidated grade sheet (R2021 clause 15.5.3, R2025 clause 21.10), and VTU uses CGPA × 10 (Examination Manual 2024; 2025 regulations clause 25OB 26.0).

Limitations

• Your university’s grade card is the official SGPA. Rules such as grace marks, moderation, relative grading, minimum marks in the end-semester exam or audit/non-credit courses are not applied.
• Only the university tables listed are built in; for any other university, copy its table into Custom from the regulation that applies to your batch.
• Up to 100 courses, 0–40 credits each.
