SGPA Calculator
Calculate your Semester Grade Point Average (SGPA) quickly and accurately. Add your semester courses, assign credit hours and grade points, and see your credit-weighted SGPA and equivalent percentage in real-time.
Calculate Your Semester Grade (SGPA)
Formula: SGPA = Total Grade Points Earned / Total Course Credits = Σ(Cᵢ × Gᵢ) / ΣCᵢ
How SGPA is Calculated Step-by-Step
SGPA (Semester Grade Point Average) measures a student's academic performance in a single semester. Unlike an unweighted arithmetic average of marks, SGPA takes into consideration the academic workload (credit hours) of each subject:
Example Calculation:
| Course Title | Course Credits (C) | Letter Grade | Grade Point (G) | Credit Points (C × G) |
|---|---|---|---|---|
| Data Structures & Algorithms | 4 | A+ | 9 | 4 × 9 = 36 |
| Computer Architecture | 4 | A | 8 | 4 × 8 = 32 |
| Discrete Mathematics | 3 | B+ | 7 | 3 × 7 = 21 |
| Object Oriented Programming | 3 | O | 10 | 3 × 10 = 30 |
| Algorithms Laboratory | 2 | O | 10 | 2 × 10 = 20 |
| Technical Communication | 2 | A | 8 | 2 × 8 = 16 |
| Total | 18 Credits | — | — | 155 Points |
SGPA = 155 / 18 = 8.61 SGPA.
Standard 10-Point Letter Grade to Grade Point Mapping
| Letter Grade | Performance Standing | Standard Grade Point (10-Point Scale) | Conventional Marks Range |
|---|---|---|---|
| O | Outstanding | 10 | 90% to 100% |
| A+ | Excellent | 9 | 80% to 89% |
| A | Very Good | 8 | 70% to 79% |
| B+ | Good | 7 | 60% to 69% |
| B | Above Average | 6 | 55% to 59% |
| C | Average | 5 | 50% to 54% |
| P | Pass | 4 | 40% to 49% |
| F / Ab | Fail / Absent | 0 | Below 40% |
Frequently Asked Questions — SGPA Calculation
What is the difference between SGPA and CGPA?
SGPA represents your performance in one specific semester. CGPA is the cumulative average across all completed semesters from semester 1 to your current semester. Once you finish all semesters, your final CGPA determines your graduation honors. Read our comprehensive guide on the difference between CGPA and SGPA.
How do I convert SGPA to percentage?
Under standard CBSE/AICTE multiplier rules, multiply your SGPA by 9.5: Percentage = SGPA × 9.5. If you attend an autonomous engineering institution like VTU, subtract 0.75 and multiply by 10. Check our dedicated SGPA to Percentage Converter for university-specific formulas.
