JNTUK Grading System
JNTUK uses a 10-point absolute grading system across all B.Tech regulations. Grades run from O (10 points) to F (0 points). Semester performance calculates as SGPA. Overall degree performance calculates as CGPA. R16 onwards students convert CGPA to percentage using (CGPA – 0.75) x 10. R13 and R10 students use (CGPA – 0.5) x 10.
The regulation printed on your marksheet determines which formula applies. Use the JNTUK CGPA to percentage calculator to get your result in one step.
What Is JNTUK and Where Does It Operate?
Jawaharlal Nehru Technological University Kakinada (JNTUK) is a public state university established in 2008 under Andhra Pradesh Act No. 30 of 2008. It emerged from the trifurcation of JNTU Hyderabad following the creation of Andhra Pradesh as a separate state. The university sits on a 110-acre campus in the port city of Kakinada, East Godavari district.
JNTUK affiliates more than 250 engineering, pharmacy, and management colleges across 11 coastal Andhra Pradesh districts, including East Godavari, Kakinada, Konaseema, West Godavari, Krishna, Guntur, and Prakasam. It serves approximately 2.3 lakh students across B.Tech, B.Pharmacy, M.Tech, MBA, MCA, and Ph.D. programs. The university holds a NAAC A+ grade and operates under UGC and AICTE recognition.
JNTUK runs on a regulation-based academic cycle. Each regulation R13, R16, R19, R20, R23 sets the credit structure, grade boundaries, passing criteria, and examination pattern for students admitted under that year. The 10-point grading scale has stayed consistent across all regulations, but the letter-to-grade-point mapping has changed between them. That distinction matters more than most students realise when calculating their percentage.

JNTUK covers Andhra Pradesh. JNTUH covers Telangana. Both share the same parent institution and similar grading heritage, but operate as completely independent universities. If your degree was issued by JNTUH, use the JNTUH grading system and calculator instead.
What Do the JNTUK Letter Grades Actually Mean?
JNTUK assigns letter grades based on fixed mark ranges. Every student scoring in the same range receives the same grade. No curve applies. The scale runs from O (Outstanding at 90-100 marks) down to F (Fail at below 40 marks), with grade points assigned on a 10-point scale.
The table below covers R16, R20, and R23 regulations, which share the same grade-to-point mapping.
Marks Range | Letter Grade | Grade Points | Performance Level |
90 – 100 | O | 10 | Outstanding |
80 – 89 | S | 9 | Excellent |
70 – 79 | A | 8 | Very Good |
60 – 69 | B | 7 | Good |
50 – 59 | C | 6 | Fair |
40 – 49 | D | 5 | Satisfactory (Minimum Pass) |
Below 40 | F | 0 | Fail |
Grade F requires re-examination. Grade D at 5 points is the minimum passing grade for R16, R20, and R23 students. Non-credit courses receive Satisfactory or Unsatisfactory ratings that do not count toward SGPA or CGPA.
How the Same Letter Grade Means Different Points Across R19, R20, and R23
Grade A in R19 carries 9 grade points. Grade A in R20 carries 8 grade points. Same letter. Different value. This is the most common calculation error JNTUK students make, and almost no competing page explains it clearly.
R19 uses a different letter assignment because its grade boundaries were calibrated under a different mark distribution structure. A student comparing marksheets from two batches one R19, one R20 sees the same letter but arrives at a different SGPA. That gap comes from the regulation table, not from a difference in performance.
Letter Grade | R19 Grade Points | R20 / R23 Grade Points |
A+ | 10 | — |
O / S | — | 10 / 9 |
A | 9 | 8 |
B | 8 | 7 |
C | 7 | 6 |
D | 6 | 5 |
E | 5 | — |
F | 0 | 0 |
Identify your regulation first. Apply its specific table. The percentage formula then follows from that table’s grade point output, which connects directly to how JNTUK calculates SGPA.
How Does JNTUK Calculate SGPA at the End of Each Semester?
JNTUK calculates SGPA using the formula: SGPA = Summation of (Credits x Grade Points) divided by Total Credits. This covers one semester only. It shows your performance in that semester’s subjects, weighted by how many credits each subject carries.
Here’s a worked example for a Semester 1 student under R20:
Subject | Credits | Grade | Grade Points | Credit Points |
Mathematics | 4 | A | 8 | 32 |
Physics | 3 | S | 9 | 27 |
Programming | 3 | B | 7 | 21 |
Engineering Drawing | 2 | A | 8 | 16 |
Total | 12 |
|
| 96 |
SGPA = 96 divided by 12 = 8.0. That result covers this semester only. SGPA should never appear on a job application or admission form as your overall academic performance. CGPA is the number that counts for placements, government recruitment, and postgraduate admissions.
What Happens to SGPA When a Student Has a Backlog Subject?
Failed subjects carry 0 grade points and stay in the SGPA calculation. They do not get excluded. A student who fails one 4-credit subject in a 12-credit semester contributes 0 to those credit-point slots, which pulls the weighted average down significantly.
Clearing the backlog in a later semester adds the grade points in that semester’s SGPA. The original semester’s SGPA stays on record unchanged. This is why clearing backlogs early matters the longer a failed subject sits, the more semesters of CGPA it drags before the credit is recovered. That credit recovery connects directly to how CGPA builds across the full degree.
How Does JNTUK Calculate CGPA Across All Eight Semesters?
JNTUK calculates CGPA as the credit-weighted average of SGPA scores across all completed semesters. The formula is: CGPA = Summation of (Credits per Semester x SGPA) divided by Total Credits across all semesters. Higher-credit semesters carry more weight in the final number.
A final-year semester typically carries 22-24 credits. A weak performance there hurts CGPA more than a weak first semester at 18 credits. Think of it like a weighted average on a weighing scale heavier semesters tip the balance more than lighter ones.
Semester | Credits | SGPA | Credits x SGPA |
Semester 1 | 18 | 7.5 | 135 |
Semester 2 | 20 | 8.2 | 164 |
Total | 38 |
| 299 |
CGPA = 299 divided by 38 = 7.87. This two-semester model scales across all eight semesters in the same way. Each semester’s SGPA gets multiplied by its credits before all values sum and divide by the total credit count.
Why Lateral Entry Students Get a Lower CGPA Percentage Than Regular Students
Lateral entry students join JNTUK in Semester 3, skipping Semesters 1 and 2. Their total credit pool across the degree covers Semesters 3 through 8 only. Two students with identical SGPA performance from Semester 3 onwards can produce different percentage outputs because the credit denominator differs.
This is why lateral entry students frequently report lower percentages than batchmates with similar grades. The formula works correctly the structure of lateral entry creates the gap. For individual semester verification before calculating cumulative performance, the
For individual semester verification, the SGPA to percentage calculator shows semester-level output separately from cumulative performance. Converting that SGPA correctly into a
depends on the regulation-specific formula covered in the next section.
How Do You Convert JNTUK CGPA to Percentage for Job Applications and Admissions?
The official JNTUK CGPA to percentage formula for R16, R19, R20, and R23 regulations is: Percentage = (CGPA – 0.75) x 10. This is the only accepted formula for background verification. Using any other multiplier produces a figure that does not match the university’s issued conversion certificate.
The JNTUK CGPA to percentage calculator applies this formula automatically for R16 through R23 regulations. The reference table below shows exact percentage outputs for common CGPA values.
CGPA | Percentage | Classification |
10.0 | 92.5% | First Class with Distinction |
9.5 | 87.5% | First Class with Distinction |
9.0 | 82.5% | First Class with Distinction |
8.5 | 77.5% | First Class with Distinction |
8.0 | 72.5% | First Class with Distinction |
7.5 | 67.5% | First Class |
7.0 | 62.5% | First Class |
6.5 | 57.5% | Second Class |
6.0 | 52.5% | Second Class |
5.5 | 47.5% | Pass Class |
5.0 | 42.5% | Pass Class |
Government job forms, GATE applications, and postgraduate admissions all use the percentage figure from this formula. Always apply it to your cumulative CGPA not your SGPA for official submissions.
Why Does the JNTUK Formula Subtract 0.75 Before Multiplying?
JNTUK’s grading scale has its passing floor at grade D or E (5 points), not at zero. Direct multiplication by 10 assumes a zero-base scale. The 0.75 subtraction corrects for the floor difference so the converted percentage accurately reflects performance relative to the actual scale boundaries.
A CGPA of 10.0 converts to 92.5%, not 100%. That’s intentional. Students who think the formula is wrong are applying a zero-base assumption to a scale that starts at 5. The formula is correct the mental model needs updating. Think of a thermometer that starts at 5 instead of 0: reading 8 on that thermometer does not mean 80 degrees on a standard scale.
R13 and R10 Students Use a Different Formula — Here’s Why
Older regulations used (CGPA – 0.5) x 10. The calibration difference between R13 and R16 produced a 0.25-point adjustment in the subtraction factor. Applying the R16 formula to an R13 transcript inflates percentage by 2.5 points.
At CGPA 7.5, that 2.5-point inflation is the difference between 67.5% and 70% which crosses the First Class with Distinction boundary. Recruiters running background checks against JNTUK records catch this discrepancy. Use the formula that matches the regulation code on your marksheet header.
What Percentage Do You Need for First Class and Distinction at JNTUK?
JNTUK classifies degrees into four tiers: First Class with Distinction, First Class, Second Class, and Pass Class. The classification threshold for First Class with Distinction sits at a CGPA of 7.75, which equals 75% under the official conversion formula.
Classification | CGPA Required | Equivalent Percentage |
First Class with Distinction | 7.75 and above | 75% and above |
First Class | 6.75 to 7.74 | 65% to 74.9% |
Second Class | 6.25 to 6.74 | 55% to 64.9% |
Pass Class | 5.25 to 6.24 | 45% to 54.9% |
Government job forms, APPSC applications, and central recruitment forms use these classification names. The CGPA column shows where you stand before conversion. The percentage column gives the figure to write on the form.
How Does the JNTUK Grading System Change Between R23, R20, R19, and R16?
The CGPA to percentage conversion formula stays the same across R16, R19, R20, and R23. What changes between regulations: the letter-to-grade-point mapping, credit distribution per semester, and how internal versus external marks split within each subject.
Internal assessment carries 25 marks. End-semester examination carries 75 marks. These proportions have stayed consistent, but credit totals per semester have been adjusted in newer regulations. A student under R23 may carry a different credit load per semester than an R19 student in the same year of study.
The letter-to-grade-point mismatch between R19 and R20 (covered in Section 1) is the most operationally important difference. Two students with the same letter grades but different regulations will arrive at different SGPAs, CGPAs, and final percentages even before the conversion formula applies.
How to Read Your Regulation From Your JNTUK Marksheet
Your regulation code appears on your marksheet header and on your hall ticket. It reads as R followed by the last two digits of the year the regulation was introduced. R23 means the 2023 academic regulation, applicable to students admitted in 2023-24 onwards.
Step 1: Check your marksheet header or hall ticket for the code.
Step 2: Match the code to the grade table for that regulation (R19 table vs R20/R23 table as shown above).
Step 3: Apply the correct grade points from that table when calculating SGPA.
The conversion formula (CGPA – 0.75) x 10 then applies uniformly regardless of regulation.
JNTUK vs JNTUH: Which University Issued Your Degree?
JNTUK covers Andhra Pradesh. JNTUH covers Telangana. Both came from the same parent institution JNTU Hyderabad after the 2014 state bifurcation. They share the same grading heritage and currently use the same conversion formula, but operate as completely independent universities with separate examination boards.
A JNTUH regulation circular does not apply to JNTUK students. A JNTUK academic notification does not govern JNTUH-affiliated colleges. Background verification agencies check against the issuing university’s specific records. Submitting JNTUK conversion documentation for a JNTUH degree or vice versa creates a verification mismatch that recruiters and admission offices flag.
Telangana students under JNTUH jurisdiction should use the JNTUH grading system and calculator. The grading structure mirrors JNTUK’s, but the official documents and verification records are separate.
What Are the Minimum Pass Marks and Attendance Rules at JNTUK?
JNTUK students need a minimum of 35% in the end-semester examination (26.25 out of 75 marks) and 40% in the total aggregate combining internal and external marks (40 out of 100) to pass a subject. Both conditions must be satisfied independently passing the aggregate without meeting the external minimum does not clear the subject.
Attendance below 75% bars a student from sitting the semester examination. Condonation applies between 65% and 75% attendance on submission of a medical certificate with a prescribed fee. Grace marks of 0.15% apply to students failing one or two subjects by 1 to 3 marks this converts a marginal fail to a pass in borderline cases.
Students who fail a subject receive grade F (0 points) in that subject’s SGPA calculation. The subject stays in the calculation and pulls down the semester average. Clearing it in a supplementary examination adds the new grade to the subsequent semester’s SGPA, but the original semester’s record stays unchanged.
FAQ
Is grade E a pass or fail at JNTUK?
Grade E carries 5 grade points and counts as a pass under R19 regulation. Under R20 and R23, grade D at 5 points serves the same minimum-pass function. Grade F at 0 points is a fail in all regulations and requires re-examination before the credit counts toward the degree.
My marksheet shows SGPA which number do I use for job applications?
Always use CGPA. SGPA covers one semester and does not represent full degree performance. Submitting SGPA where CGPA is required misrepresents your academic record and creates a mismatch during background verification.
Does the JNTUK grading formula apply the same way for B.Pharmacy and MBA?
The 10-point scale and conversion formula apply across B.Tech, B.Pharmacy, M.Tech, MBA, and MCA programs at JNTUK. Credit structures differ by program. Verify your program’s regulation document for the exact credit distribution per semester, as MBA and MCA semester credit loads differ from B.Tech.
Is JNTUK percentage accepted for APPSC and central government recruitment?
The percentage produced by JNTUK’s official formula applies directly to APPSC and central government eligibility checks. Use the figure from your official conversion certificate downloaded from jntuksdc.co.in not a self-calculated estimate for formal submissions.
What is the maximum CGPA at JNTUK and what percentage does it produce?
The maximum CGPA at JNTUK is 10.0. Under the R16-onwards formula, that converts to 92.5% not 100%, because the formula corrects for the grading scale’s floor at 5 points. A CGPA of 10.0 means a student scored in the O (Outstanding) band across every subject in every semester.
