What is an SGPA Calculator?
SGPA (Semester Grade Point Average) represents academic performance for a single semester under the Choice-Based Credit System (CBCS) used by most Indian universities. It is calculated by dividing the sum of (credit × grade point) for all subjects by total credits earned that semester.
SGPA is then used to calculate CGPA across all semesters. Converting SGPA to percentage (SGPA × 9.5 for 10-point scale) gives an approximate equivalent percentage for use in applications and resumes.
lightbulb Example Calculation
Scenario: Priya Krishnan, 2nd year B.Tech student at NIT Trichy — Semester 3 results: Physics (4 cr, O=10), Maths (4 cr, A+=9), Chemistry (3 cr, A=8), Programming (4 cr, O=10), English (2 cr, A+=9)
1Weighted sum = (4×10) + (4×9) + (3×8) = 40+36+24 = 100
2Total credits = 4 + 4 + 3 = 11
3SGPA = 100 / 11 = 9.09 → Percentage ≈ 86.36%
✓ Result: SGPA 9.09 — Outstanding (O Grade)
help_outlineHow to Use the SGPA Calculator
- Select the total number of subjects for this semester from the dropdown — options range from 2 to 8 subjects.
- For each subject, enter the subject name, select the credit value, and choose the letter grade (O, A+, A, B+, B, C, P, F) from the dropdown.
- Results update live as you change grades and credits — SGPA and the equivalent percentage (SGPA × 9.5) are shown with a subject-wise grade points breakdown.
- To compute cumulative CGPA: enter previous semester SGPAs and credit counts in the Cumulative CGPA section below, then click "Calc CGPA."
- Review pass/fail status — SGPA ≥ 4 (P grade equivalent) is required to avoid academic probation in most universities.

quizFrequently Asked Questions
What is the difference between SGPA and CGPA?
SGPA (Semester GPA) is calculated fresh each semester from only that semester's subjects and credits. CGPA (Cumulative GPA) is the running weighted average of all completed semester SGPAs, with each semester's SGPA weighted by its total credits. A single great semester improves SGPA substantially but has a diminishing impact on CGPA as more semesters accumulate. CGPA is what appears on your final degree and is used by employers and graduate school admission committees.
How is SGPA converted to percentage?
The standard AICTE-recommended formula is: Percentage = SGPA × 9.5. Example: SGPA 8.0 → 8.0 × 9.5 = 76%. This formula is not universal — some universities use different multipliers (e.g., Anna University uses specific lookup tables; Mumbai University may use different factors for different programmes). Always verify with your university's official academic regulations or the equivalency certificate issued by the registrar, especially for job applications specifying minimum percentage requirements.
What happens if I score an F grade in a subject?
An F grade assigns 0 grade points for that subject, but the credits still count in the SGPA denominator — this significantly lowers SGPA. Example: scoring F in a 4-credit subject in an 18-credit semester adds 0 to the numerator but 4 to the denominator, pulling SGPA toward zero by 4 units. You must clear the subject in a supplementary (back-paper) examination. Most universities allow repeated attempts but cap the replacement grade at B or P, and flag it on the transcript as a repeat attempt.
Is SGPA ≥ 4 required to pass the semester?
Under UGC-CBCS guidelines, P (Pass) grade requires a grade point of 4 or above. An SGPA below 4 indicates the student has failed one or more subjects. However, the specific pass rule varies by institution: some require passing every individual subject; others allow carrying one or two failed subjects to the next semester with conditional promotion; some use a minimum SGPA threshold for promotion. Always refer to your university's specific academic regulations — this calculator shows the SGPA and flags pass/fail based on the P-grade threshold.
How do I plan my CGPA target using this calculator?
Use the "what-if" approach: enter expected grades for current semester subjects to see the projected SGPA. Then enter past semester SGPAs and their credit totals in the Cumulative CGPA section — the tool computes your projected CGPA assuming your expected SGPA for the current semester. Work backward: if you need a CGPA of 8.0 by end of 8th semester and currently have CGPA 7.5 after 6 semesters, calculate what SGPA is required in semesters 7 and 8 to bridge that gap.
