The Official JNTU Credit and Grading System (R16, R18, R19, R20, R22 Regulations)
Jawaharlal Nehru Technological University (JNTU) is the premier technological university system across Telangana and Andhra Pradesh. It encompasses four major universities:
- JNTU Hyderabad (JNTUH): Kukatpally, Hyderabad, Telangana.
- JNTU Kakinada (JNTUK): Kakinada, Andhra Pradesh.
- JNTU Anantapur (JNTUA): Anantapuramu, Andhra Pradesh.
- JNTU Gurajada Vizianagaram (JNTUGV): Vizianagaram, Andhra Pradesh.
Together, these universities affiliate over 400 engineering, pharmacy, and management colleges (including top colleges like CBIT, VNR VJIET, Gokaraju Rangaraju, Vasavi, and Gayatri Vidya Parishad).
Under JNTU's 10-point letter grading system, students earn Grade Points (O: 10, A+: 9, A: 8, B+: 7, B: 6, C: 5, F: 0) based on absolute/relative percentage bands.

The Official JNTU Conversion Formula: (CGPA - 0.50) × 10 (Senate Resolution)
Per the official academic regulations notifications issued by the Directorate of Evaluation of JNTU (for R18, R19, R20, and R22 regulations):
For example, a JNTU B.Tech graduate with a 7.80 CGPA secures: (7.80 - 0.50) × 10 = 7.30 × 10 = 73.00%.
Variations across JNTUH, JNTUK, JNTUA and JNTUGV
While all four JNTU universities follow AICTE credit guidelines, specific regulations apply:
- JNTUH (R18 / R22 Regulations): Governed universally by Percentage = (CGPA - 0.50) × 10.
- JNTUK (R19 / R20 Regulations): Uses Percentage = (CGPA - 0.50) × 10 printed on the Consolidated Marks Memo (CMM).
- JNTUA (R19 / R20 Regulations): Aligned with Percentage = (CGPA - 0.50) × 10.
- Older R16 Scheme: Certain autonomous colleges applied
(CGPA - 0.75) × 10. Check the back of your official CMM transcript for autonomous college variations.

How to Calculate Cumulative CGPA from 8 Semester SGPAs (160 Credit Framework)
Cumulative CGPA is computed using the credit-weighted sum of SGPAs:
Under JNTU R18, R20, and R22 regulations, a regular 4-year B.Tech degree comprises exactly 160 credits (ranging from 15 to 22 credits per semester).
JNTU Degree Award Classifications: Distinction (FCD), First Class and Second Class
According to JNTU Academic Regulations:
- First Class with Distinction (FCD): Final CGPA ≥ 8.00 (≥75.00%), provided the candidate passed all subjects in first attempt within 4 years with zero backlogs.
- First Class (FC): Final 6.50 ≤ CGPA < 8.00 (60.00% to 74.99%).
- Second Class (SC): Final 5.50 ≤ CGPA < 6.50 (50.00% to 59.99%).
- Pass Class (P): Final 5.00 ≤ CGPA < 5.50 (45.00% to 49.99%).
Step-by-Step Solved B.Tech 8-Semester Conversion Examples
Example 1: JNTUH B.Tech CSE Graduate (CGPA: 8.32)
Consider a JNTUH CSE graduate with an 8.32 CGPA:
Calculation: (8.32 - 0.50) × 10 = 7.82 × 10 = 78.20%
Class Award: First Class with Distinction (FCD).
Example 2: Reverse Conversion (Target 65.00% Placement)
To find the CGPA required for a 65.00% aggregate in JNTU:
Calculation: (65.00 / 10) + 0.50 = 6.50 + 0.50 = 7.00 CGPA

Frequently Asked Questions (FAQs)
As per the official Academic Regulations (R18, R20, and R22 for JNTUH, JNTUK, and JNTUA), the formula for converting 10-point CGPA to percentage is: Percentage of Marks (%) = (CGPA - 0.50) × 10.
In JNTU, a candidate is awarded 'First Class with Distinction' if they secure a final CGPA of 8.00 or higher (equivalent to 75.00%+) and have completed all theory and laboratory subjects in the first attempt within 4 consecutive academic years without any backlogs.
To achieve exactly 60.00% marks under the JNTU conversion formula [(6.50 - 0.50) × 10 = 60.00%], a student must secure a minimum CGPA of 6.50 (First Class).
CGPA is calculated using the credit-weighted sum of SGPAs: CGPA = Σ(SGPA of Semester i × Credits of Semester i) / Σ(Total B.Tech Credits across 8 semesters, exactly 160 credits under R18/R20/R22).
Under the older R16 regulation, certain JNTU campuses followed the AICTE standard formula Percentage = (CGPA - 0.75) × 10. From R18 onwards, the unified formula (CGPA - 0.50) × 10 has been universally adopted.
Under JNTU academic regulations, the minimum passing CGPA for the award of a B.Tech degree is 5.00 (equivalent to 45.00% marks - Pass Class).
