(Jawaharlal Nehru Technological University Kakinada) JNTUK CGPA Calculator & Percentage Converter

Please Note - I searched for references on the Jawaharlal Nehru Technological University Kakinada (JNTUK) website but could not find them. The below calculation is based on JNTUH. However, the formulas are the same for SGPA and CGPA, but the CGPA conversion into percentage may differ.

JNTUK SGPA Calculator







Course Grade Credits Action
Below, we will discuss about the formulas, examples, etc. \[\text{SGPA} = \frac{\sum_{i=1}^{n} C_i G_i}{\sum_{i=1}^{n} C_i} \]

where

  • Ci = Number of credits earned in the ith course of a semester for which SGPA is to be calculated.
  • n = The no. of subjects ‘registered’ for the semeste
  • Gi = Grade point earned in the ith course.
  • i = The subject indicator index (takes into account all subjects in a semester.

Example of SGPA Calculation

Course/Subject Credit Letter Grade Grade Point Credit Points
Course 1 3 A 8 3 × 8 = 24
Course 2 3 B 6 3 × 6 = 18
Course 3 4 O 10 4 × 10 = 40
Course 4 4 C 5 4 × 5 = 20
Course 5 3 A+ 9 3 × 9 = 27
Course 6 3 A 8 3 × 8 = 24
20 153
\[ \text{SGPA} = \frac{153}{20} = {7.65}\% \]

The formula for CGPA Calculator at JNTUK

\[\text{CGPA} = \frac{\sum_{i=1}^{m} C_j G_j}{\sum_{i=1}^{m} C_j} \]

where

  • Cj = Number of credits earned in the jth course of the Programme for which CGPA is to be calculated
  • m = The total no. of subjects (as specifically required and listed under the course structure of the parent department) the student has ‘registered’ i.e., from the 1st semester onwards up to and inclusive of the 8th semester,
  • Gj = Grade point earned in the jth course; A grade lower than D(i.e. grade point < 4 ) in a course shall not be taken into account
  • j = The subject indicator index (takes into account all subjects from 1 to 8 semesters)

Example of CGPA Calculation

Semester Credits SGPA Credit × SGPA
Semester I 24 8 24 × 8 = 192
Semester II 24 9 24 × 9 = 216
Semester III 24 8 24 × 8 = 192
Semester IV 24 7 24 × 7 = 168
Semester V 24 6.5 24 × 6.5 = 156
Semester VI 24 7.5 24 × 7.5 = 180
Semester VII 24 8.5 24 × 8.5 = 204
Semester VIII 24 8.5 24 × 8.5 = 204
192 1512
\[ \text{CGPA} = \frac{1512}{192} = {7.87}\% \]

The formula can also be written as

\[ \text{SGPA/CGPA} = \frac{\sum(Grade \; Point \times Credits)}{\sum Credits} \]

Where:

  • Grade Point is the grade point corresponding to the grade obtained in the course (typically on a scale from 0 to 10).
  • Credit is the credit weightage assigned to the course.

JNTUK CGPA to Percentage Converter


Please note, the JNTUH has released many notifications where they claimed different CGPA to Percentage conversion formulas, which is very confusing.

It is your responsibility to check the multiplying factor for the conversion.

The formula for conversion from CGPA to percentage is:

\[ \text{Percentage} = (\text{CGPA} - 0.5) \times 10 \]

For example, if the CGPA is 9.3, then the percentage would be:

\[ \text{Percentage} = (9.3 - 0.5) \times 10 = 88.00\% \]
