━━━ INDIAN UNIVERSITIES ━━━
CBSE / Delhi University / JNU / BHU:
Percentage = CGPA × 9.5
IITs / IISc / BITS / AKTU / Osmania:
Percentage = CGPA × 10
Anna University / NITs / Manipal:
Percentage = (CGPA − 0.5) × 10
VTU / JNTU / MDU / Kurukshetra:
Percentage = (CGPA − 0.75) × 10
Mumbai University (unique):
Percentage = 7.1 × CGPA + 11
━━━ CONVERSIONS ━━━
Indian CGPA → US GPA:
US GPA ≈ Indian CGPA × 0.4 (linear)
US GPA → Indian CGPA:
Indian CGPA ≈ US GPA × 2.5
━━━ CUMULATIVE FORMULAS ━━━
SGPA = Σ(Course GP × Course Credits)
÷ Σ(Course Credits)
CGPA = Σ(SGPA × Semester Credits)
÷ Σ(Total Credits)
✨ Why Use CGPACalculation.store?
⭐⭐⭐⭐⭐
"Most comprehensive academic toolkit I've used. Found my specific university (Anna) calculator with the right formula — saved me from misreporting on TCS application."
— Engineering student, Chennai
⭐⭐⭐⭐⭐
"The SGPA-to-CGPA walkthrough mode is gold. Helped me actually understand the math instead of just plugging numbers."
— CS undergrad, Delhi
⭐⭐⭐⭐⭐
"Detailed comparison of US 4.0 vs Indian 10-point conversion methods. Realized WES results would differ from my self-estimate by 0.3 — very helpful for grad school apps."
— MS aspirant, Mumbai
💡 Built for accuracy & transparency: Every calculator on this site uses official university/board formulas, verified against 2026 academic regulations. Multiple conversion methods are shown side-by-side so you understand the range and uncertainty. For formal applications, we always recommend professional credential evaluation (WES, ECE) — our tools are for estimation, planning, and learning.
❓ Frequently Asked Questions
CGPA (Cumulative Grade Point Average) is the weighted average of all completed semesters across your entire degree program. GPA typically refers to a single semester's grade average (also called SGPA), or in US context, the cumulative score on a 4.0 scale. CGPA is more common in India, Bangladesh, Pakistan, and other South Asian countries on a 10-point scale. GPA is more common in the US (4.0 scale), Canada, Singapore, and many Western countries. Both follow the same fundamental credit-weighted averaging formula — just expressed on different scales.
Use the credit-weighted average formula: CGPA = Σ(Course Grade Points × Course Credits) / Σ(Course Credits). For multi-semester CGPA: CGPA = Σ(SGPA × Semester Credits) / Σ(Total Credits). The key insight is that semesters with more credits have proportionally more impact on your cumulative CGPA than lighter semesters. Simple averaging of SGPAs is WRONG unless all your semesters have identical credit hours. Use our calculator above or visit How to Calculate CGPA for detailed step-by-step instructions.
The × 9.5 rule is CBSE's official conversion formula: Percentage = CGPA × 9.5. Used by CBSE schools (Class 10/12), Delhi University, JNU, BHU, Jamia Millia Islamia, and most central universities. Mathematically derived from the fact that grade O (10 grade points) corresponds to the 90-100% band with midpoint 95% — giving 10 × 9.5 = 95%. However, engineering universities use different formulas: IITs use × 10, Anna University uses (CGPA−0.5)×10, VTU/JNTU use (CGPA−0.75)×10, Mumbai University uses 7.1×CGPA+11. Always verify your specific university's formula.

We're supported by minimal contextual advertising that doesn't interfere with calculation accuracy or speed.
Three common methods: (1) Linear scaling — Indian CGPA × 0.4 (e.g., 8.0 CGPA × 0.4 = 3.2 US GPA). (2) Percentage bridge — Indian CGPA × 9.5 → percentage → US letter grade. (3) WES proxy — band-by-band mapping similar to official WES evaluation. For formal applications to US/Canadian universities, always use professional credential evaluation services like WES ($220) rather than self-conversion. Methods can differ by 0.5-1.0 GPA points in middle ranges. See our CGPA to GPA Calculator for detailed comparison.
Each university chose its formula to maintain backward compatibility with its pre-CBCS percentage standards. CBSE/DU adopted × 9.5 (midpoint-anchored). IITs use × 10 (top-anchored). Anna/NITs use (CGPA−0.5)×10 (conservative). VTU/JNTU use (CGPA−0.75)×10 (most conservative). Mumbai uses 7.1×CGPA+11 (unique non-linear). For the same 7.5 CGPA, you might get 71.25% (CBSE/DU), 75% (IIT), 70% (Anna), 67.5% (VTU), or 64.25% (Mumbai). Always use YOUR university's official formula on resumes, job applications, and government exams to avoid misrepresentation.
Indian context: 6.0+ minimum for service IT companies (TCS/Infosys/Wipro), 7.5+ for product companies (Microsoft/Amazon), 8.0+ for tier-1 consulting (MBB), 8.5+ for IIM/IIT MTech. US grad school: 3.0+ general minimum, 3.5+ for top-50, 3.7+ for top-20 (MIT/Stanford). UK universities: 2:1 (60%+) is the "good degree" threshold; First Class (70%+) for top opportunities.

Depends on your university's retake policy. Most Indian universities use grade replacement (better grade replaces F) which makes retaking failed courses very beneficial. Some universities (like FAST-NUCES Pakistan) use latest-grade-replaces regardless — retaking is risky if you might score lower. US universities often average both attempts. Generally safe to retake F, D, or D+. Risky to retake C+ or higher. Use our GPA Improvement Calculator to model the exact impact before deciding.
We have 15+ university-specific calculators including Delhi University, Mumbai, Anna, VTU, JNTU, MDU, SPPU Pune, Osmania, KTU Kerala, RTU Kota, Bangalore, Calicut, FAST-NUCES (5 Pakistani campuses), and LUMS Pakistan. If your specific university isn't listed, use our generic 10-point CGPA calculator (for Indian universities) or 4-point GPA calculator (for US/Canadian universities). For accurate conversion to percentage, identify your university's official formula from its Academic Regulations and use our CGPA to Percentage Calculator with manual formula entry.
For pure CGPA/GPA calculations using credit-weighted averaging, our calculators are mathematically accurate to 2-3 decimal places. For CGPA-to-percentage conversion at universities with published formulas (× 9.5, × 10, (CGPA−0.5)×10, etc.), accuracy depends on whether your university follows that specific formula — verify in your Academic Regulations. For international conversions (Indian CGPA → US GPA), all formula-based methods are approximations and can differ by 0.2-0.5 GPA. For formal applications, always use professional credential evaluation services like WES.
Some universities have unique formulas not directly available in our calculator (e.g., Mumbai's 7.1×CGPA+11, SPPU's Circular 332/2020 piecewise, or specific institutional variations). Solutions: (1) Check our Universities Index — we may have a specific calculator. (2) Request a Conversion Certificate from your Controller of Examinations — they'll compute officially. (3) Use the manual formula entry option in our CGPA-to-Percentage Calculator. (4) Email us via Contact with your specific formula, and we'll add a calculator for your university.
