Can I calculate my JNTUK CGPA before completing all 8 semesters?

Yes. The calculator computes a running CGPA based on the semesters you have completed so far. Enter the SGPA and total credits for each completed semester and click Calculate CGPA.

Does this JNTUK calculator work for R20, R19, and R16 regulations?

Yes. The CGPA calculator works for all regulations since the CGPA formula is the same. The SGPA calculator lets you select your regulation (R20/R16 or R19) so the correct grade point scale is applied automatically.

What is the difference between JNTUK R19 and R20 grading?

The grade labels differ between R19 and R20/R16. In R20/R16: O=10, S=9, A=8, B=7, C=6, D=5. In R19: A+=10, A=9, B=8, C=7, D=6, E=5. An 'A' in R19 equals 9 points whereas an 'A' in R20 equals 8 points — always check your regulation before comparing.

JNTUK CGPA Calculator – R20 / R19 / R16 Official Formula

Q: What is the JNTUK grading scale for R20 / R16?

Under R20 and R16 regulations, JNTUK uses: O = 10 (Outstanding), S = 9 (Excellent), A = 8 (Very Good), B = 7 (Good), C = 6 (Above Average), D = 5 (Average), F = 0 (Fail). Under R19, the scale is A+ = 10, A = 9, B = 8, C = 7, D = 6, E = 5, F = 0.

Q: How is JNTUK CGPA converted to percentage?

For R16 regulations onwards (R16, R19, R20, R23), JNTUK uses the formula: Percentage = (CGPA − 0.75) × 10. For example, a CGPA of 8.5 converts to (8.5 − 0.75) × 10 = 77.5%. Students under older R13 or R10 regulations use (CGPA − 0.5) × 10 instead.

Q: What is the minimum CGPA to pass at JNTUK?

At JNTUK, the minimum grade required to pass a subject is D (5 grade points) under R20/R16, or E (5 grade points) under R19. A student must secure all 160 credits to be eligible for the B.Tech degree.

Q: Where can I download my official JNTUK CGPA certificate?

You can download your official JNTUK CGPA/percentage conversion certificate from jntuksdc.co.in using your hall ticket number. This certificate is required for formal submissions to employers, higher studies, and government applications.

The Math

JNTUK CGPA Formula

Per the official R20 / R19 / R16 academic regulations published by JNTUK.

JNTUK CGPA Formula

\[ \text{CGPA} = \frac{\displaystyle\sum_{j=1}^{m} C_j \times G_j}{\displaystyle\sum_{j=1}^{m} C_j} \]

C_jCredits earned in the j-th course

G_jGrade point earned in the j-th course

mTotal subjects from Semester 1 to 8

📝 Worked Example

A B.Tech (R20) student has completed all 8 semesters. Their semester-wise SGPA and credits are:

Semester	SGPA	Credits	SGPA × Credits
1st	8.2	20	8.2 × 20 = 164.0
2nd	7.6	22	7.6 × 22 = 167.2
3rd	8.8	21	8.8 × 21 = 184.8
4th	7.1	22	7.1 × 22 = 156.2
5th	9.0	20	9.0 × 20 = 180.0
6th	7.4	18	7.4 × 18 = 133.2
7th	8.5	19	8.5 × 19 = 161.5
8th	8.9	18	8.9 × 18 = 160.2
Total	—	160	1,307.1

Plugging into the formula:

\[ \text{CGPA} = \frac{1307.1}{160} \approx \mathbf{8.17} \]

And the percentage equivalent (using JNTUK's R20 formula) is:

\[ \text{Percentage} = (8.17 - 0.75) \times 10 = \mathbf{74.2\%} \]

JNTUK CGPA — Frequently Asked Questions

What is the JNTUK grading scale for R20 / R16?

Under R20 and R16 regulations, JNTUK uses a 10-point grading system:

O = 10 (Outstanding) · S = 9 (Excellent) · A = 8 (Very Good) · B = 7 (Good) · C = 6 (Above Average) · D = 5 (Average/Pass) · F = 0 (Fail).

What is the JNTUK grading scale for R19?

Under R19 regulations, JNTUK uses a different set of grade labels:

A+ = 10 · A = 9 · B = 8 · C = 7 · D = 6 · E = 5 (Pass) · F = 0 (Fail).

Note: An "A" in R19 equals 9 points, while an "A" in R20 equals 8 points. Always confirm your regulation before comparing.

How is JNTUK CGPA converted to percentage?

For R16 regulation and onwards (R16, R19, R20, R23), JNTUK uses:

Percentage = (CGPA − 0.75) × 10

Examples: CGPA 8.5 → 77.5% | CGPA 7.5 → 67.5% | CGPA 9.0 → 82.5%.

Students under older R13 or R10 regulations use: Percentage = (CGPA − 0.5) × 10.

Using the wrong formula inflates or deflates your percentage by 2.5 points — always verify your regulation from your hall ticket or transcript.

What is the minimum CGPA to pass at JNTUK?

The minimum grade to pass a subject is D (5 grade points) under R20/R16, or E (5 grade points) under R19. A student must register for and secure all 160 credits (across 8 semesters) to be eligible for the B.Tech degree award.

Can I calculate my CGPA before completing all 8 semesters?

Yes. You can compute a running CGPA based on the semesters you've completed so far. Just enter the SGPA and total credits for each finished semester and click Calculate CGPA.

How are JNTUK backlogs counted in CGPA?

An F (Fail) grade carries a grade point of 0, but the credits of that subject are still counted in the denominator of the CGPA formula. Once you clear the backlog, the passing grade replaces the F and CGPA is recomputed accordingly.

Where can I download my official JNTUK CGPA certificate?

Download your official JNTUK CGPA / percentage conversion certificate from jntuksdc.co.in using your hall ticket number. This certificate is required for placements, higher studies, and government job applications.

What is the difference between JNTUK and JNTUH CGPA calculation?

The CGPA and SGPA formulas are identical across JNTUK (Kakinada) and JNTUH (Hyderabad). The key difference is in the percentage conversion formula: JNTUK (R16 onwards) uses (CGPA − 0.75) × 10, whereas JNTUH uses (CGPA − 0.5) × 10. Never use JNTUH's formula on a JNTUK transcript — it will inflate your percentage by 2.5 points.
