OGPA Calculator

OGPA means overall grade point average. It is a weighted average of your academic grades that you have obtained in your academic program. Some universities still use OGPA instead of CGPA .They use different scales like 7 scale, 5 scale and 4 scale for their academic valuation.

OGPA and CGPA are almost similar but there are some key difference among them is that OGPA is calculated for all semesters, while CGPA is usually calculated for the end of a specific academic term.

How to Calculate OGPA?

To calculate the OGPA, you will typically use the following formula:

OGPA= ∑(Grade Points × Credit Hours)

             _________________________

                      ∑Credit Hours

Here, grade points means the grade earned in a particular course, and credit hours are the weight assigned to a particular course. 

Steps to Calculate OGPA:

Step 1: Multiply grade points with the credit hours of particular subject                        

Step 2: Add up the total weighted grade points (grade points × credit hours) for all courses.

Step 3: Add all the credit hours for all courses which you have taken.

Step 4: Divide the weighted grade points by the total credit hours to get the OGPA.

Example:

Let’s suppose  you took 3 courses with the following details:

1. For A: 8×3=248

                      = 248/times 3

                      = 24

2. For B: 7×4=287 

          = 287 /times 4

          = 28

3. For C: 9×2=189 

         =189/times 2 

         = 18

Total weighted grade points 

= 24 + 28 + 18 = 70

Total credit hours 

= 3 + 4 + 2 = 9

Now, divide the total weighted grade points by the total credit hours:

OGPA=70/9

          =7.78

How to calculate OGPA on a different scale?

OGPA (Overall Grade Point Average) is based on different scales, like 4 scales, like a 4-grade scale, a 10-grade scale, a 7-grade scale, and a 5-grade scale. It can vary on the basis of different universities, institutions, and countries. Let’s discuss them one by one.

1. 10-Point Scale 

This scale is most common among OGPA calculations. Many universities use this scale for their calculation. This grading scale is between 0 to 10, where 10 is the highest possible grade and 0 is the lowest possible grade.

This scale is very common in engineering, technology, and management schools, and in different undergraduate and postgraduate programs.

Example Grading (10-point scale):

• A+ = 10
• A = 9
• B+ = 8
• B = 7
• C+ = 6
• C = 5
• D = 4
• F (Failure) = 0

OGPA formula for 10 scale 

OGPA = ∑(Grade Points × Credits of Subject) / ∑Total Credits

Example:

For a student with the following grades in 4 subjects:

The OGPA would be calculated as:

OGPA = (9.0×3)+(8.5×4)+(7.0×2)+(8.0×3)/3+4+2+3

OGPA = (27+34+14+24)/12

=99/12

=8.25

2. 4-Point Scale

This scale is commonly used in the USA, Canada, and Australia and many other international universities. On a 4-point scale, the grades are ranged between 0 and 4, with the following general conversions:

4.0 = Excellent (A)

3.0 = Good (B)

2.0 = Satisfactory (C)

1.0 = Passing (D)

0.0 = Failing (F)

Example Grading (4-point scale):

• A = 4.0
• B = 3.0
• C = 2.0
• D = 1.0
• F (Failure) = 0.0

OGPA = (Cumulative Credit Points from all semesters) / (Cumulative Credits from all semesters) 

Example:

For a student with the following grades:

The OGPA would be calculated as:

OGPA=(3.5×3)+(3.0×4)+(2.5×2)+(3.0×3)/3+4+2+3​

=(10.5+12+5+9)/12

=36.5/12

=3.04

3. 7-Point Scale

Some Indian universities and Europe use a 7-point scale for grading. This scale is less popular than other scales but is still used in certain regions.

The grading system might look something like this:

7 = A+ (Excellent)

6 = A (Very Good)

5 = B+ (Good)

4 = B (Average)

3 = C (Below Average)

2 = D (Poor)

1 = F (Failing)

Example Grading (7-point scale):

• A+ = 7
• A = 6
• B+ = 5
• B = 4
• C = 3
• D = 2
• F = 0

4. 5-Point Scale

The 5-point scale is used in very few universities. It is mainly used for specific programs. The grading might look like this:

• 5 = Excellent (A+)
• 4 = Good (A or B)
• 3 = Average (C)
• 2 = Poor (D)
• 1 = Fail (F)

Example Grading (5-point scale):

• A+ = 5
• A = 4
• B = 3
• C = 2
• F = 0

OGPA formula for 10 scale 

OGPA = ∑(Grade Points × Credits of Subject) / ∑Total Credits

Example:

For a student with the following grades:

The OGPA would be calculated as:

OGPA=(6.5×3)+(5.5×4)+(4.0×2)+(6.0×3)/3+4+2+3

=(19.5+22+8+18)/12

=67.5/12

=5.625

5. Letter Grades with Numerical Conversion

Some universities use letter grades for that academic valuation and for that they convert their numerical values for OGPA calculations. This conversion vary on the basis of  institution, but there is a particular system for that:

• A+ = 4.0 (or 10/10 in a 10-point scale)
• A = 3.7 (or 9/10 in a 10-point scale)
• B+ = 3.3 (or 8/10 in a 10-point scale)
• B = 3.0 (or 7/10 in a 10-point scale)
• C = 2.0 (or 5/10 in a 10-point scale)
• D = 1.0 (or 4/10 in a 10-point scale)
• F = 0 (failure)

How to Convert CGPA into OGPA ?

If you want to convert  your CGPA to OGPA there are two main methods to convert it let’s discuss them one by one.

How to convert same scale CGPA into OGPA ?

If both CGPA and OGPA are on the same scales, then

CGPA = OGPA

Example 1: CGPA (10-point scale) to OGPA (10-point scale)

If both CGPA and OGPA use the 10-point scale, then they are same

CGPA=OGPA

For example, if you have 8.0 CGPA then 

CGPA = OGPA

8.0 = 8.0

How to convert  different scale CGPA into OGPA ?

If CGPA and OGPA are based on different scale then you need calculate it with help of the formula let’s discuss them one by one

Conversion Table for CGPA to OGPA:

1. CGPA to OGPA (7-point scale)

OGPA = (CGPA × 10)/7

2. CGPA to OGPA (4-point scale)

OGPA=(CGPA×10)/4

OGPA calculation in different Indian university 

OGPA is commonly used by many universities to evaluate their student’s academic performance. Its calculation is based on university and their scale which is used for academic valuation. While the basic principle of calculation is the same, Here are  some examples from some famous universities.

1. Indian Institutes of Technology (IITs)

IITs, such as IIT Bombay, IIT Delhi, IIT Madras, and others, use a 10-point CGPA system. The calculation is based on credit-weighted grade points.

OGPA Calculation Formula:

OGPA = ∑(Grade Points × Credit Hours) / ∑Credit Hours

In this method Grade Points are assigned based on letter grades and Credit Hours refer to the credit value of the courses taken.

Grade Points Mapping (IITs):

• A+ = 10
• A = 9
• B+ = 8
• B = 7
• C+ = 6
• C = 5
• D = 4
• F = 0 (Fail)

Let’s take one quick example If a student has the following courses:

Grade = A (Grade Point = 9), Credit Hours = 4

Grade = B+ (Grade Point = 8), Credit Hours = 3

Grade = A (Grade Point = 9), Credit Hours = 2

OGPA = (9×4)+(8×3)+(9×2)/4+3+2

=(36+24+18)/9

=78/9

=8.67

2. National Institutes of Technology (NITs)

NITs also follow the 10-point CGPA system for  calculation of OGPA.

Grade Points of (NITs):

• A+ = 10
• A = 9
• B+ = 8
• B = 7
• C+ = 6
• C = 5
• D = 4
• F = 0 (Fail)

Let’s take one quick example If a student takes the following courses:

• Course 1: Grade = A+ (Grade Point = 10), Credit Hours = 3
• Course 2: Grade = B (Grade Point = 7), Credit Hours = 3
• Course 3: Grade = C+ (Grade Point = 6), Credit Hours = 2

The OGPA calculation would be:

OGPA=(10×3)+(7×3)+(6×2)/3+3+2

=(30+21+12)/8

=63/8

=7.875

3. BITS Pilani

BITS Pilani also follows a 10-point grading system, and the CGPA is calculated based on a weighted average of the grade points earned in different courses.

OGPA Calculation Formula:

OGPA = ∑(Grade Points × Credits) / ∑Credits

Grade Points Mapping  for BITS Pilani:

• A = 10
• B+ = 9
• B = 8
• C+ = 7
• C = 6
• D = 5
• F = 0

Example:

If a student has:

Grade = A (Grade Point = 10), Credit Hours = 3

Grade = B+ (Grade Point = 9), Credit Hours = 3

Grade = B (Grade Point = 8), Credit Hours = 2

The OGPA will be:

OGPA=(10×3)+(9×3)+(8×2)/3+3+2

=(30+27+16)/8

=73/8

=9.125

4. Delhi University (DU)

Delhi University has Choice Based Credit System, which is similar to 10-point CGPA scale or 4-point GPA scale, your grading scale completely depends on the undergraduate programs you choose. The DU OGPA Calculation Formula is similar to the IITs and NITs, i.e., a weighted average of grade points by credit hours.

• Grade Points Mapping (DU):
  
  • A+ = 10
  • A = 9
  • B+ = 8
  • B = 7
  • C+ = 6
  • C = 5
  • D = 4
  • F = 0

Example:

If a student takes the following courses:

Grade = A (Grade Point = 9), Credit Hours = 3

Grade = B+ (Grade Point = 8), Credit Hours = 4

Grade = A (Grade Point = 9), Credit Hours = 2

The OGPA will be:

OGPA=(9×3)+(8×4)+(9×2)/3+4+2

=(27+32+18)/9

=77/9

=8.56

5. Jawaharlal Nehru University (JNU)

JNU follows a 7-point grading system. Its calculator is based on weighted grade points similar to the 10-point grading system, but it uses a 7-point grade scale for grade calculation.

OGPA Calculation Formula:

OGPA = ∑(Grade Points × Credit Hours) / ∑Credit Hours

Grade Points Mapping 

• Grade A = 7
• Grade B = 6
• Grade C = 5
• Grade D = 4
• Grade F = 0

Example:

If a student has the following courses:

Grade = A (Grade Point = 7), Credit Hours = 4

Grade = B (Grade Point = 6), Credit Hours = 3

Grade = A (Grade Point = 7), Credit Hours = 3

The CGPA will be:

CGPA = (7×4)+(6×3)+(7×3)/4+3+3

=(28+18+21)/10

=67/10

=6.7

6. VIT University (VIT)

VIT University (VIT)  also follows a 10-point scale for OGPA calculation, and uses a similar method like IITs and NITs.

• Grade Points Mapping
  • S = 10
  • A = 9
  • B = 8
  • C = 7
  • D = 6
  • E = 5
  • F = 0

Example:

If a student has the following courses:

• Grade = A (Grade Point = 9), Credit Hours = 3
• Grade = B (Grade Point = 8), Credit Hours = 3
• Grade = C (Grade Point = 7), Credit Hours = 2

The OGPA will be:

OGPA=(9×3)+(8×3)+(7×2)/3+3+2

=(27+24+14)/8

=65/8

=8.125

OGPA calculation in different countries?

Different universities use different methods for their academic valuation. Here are some top countries examples for OGPA calculation

1. US Universities: 

US institutions use plus/minus grading (e.g., A+, A, A-, B+, B, etc.), which allows for distinctions in performance.

OGPA Calculation Formula:

OGPA = ∑(Grade Points × Credit Hours)/∑Credit Hours

Same formula, with a 4-scale point for academic evaluation.

Grade Points Mapping (4-point scale):

A = 4.0

B = 3.0

C = 2.0

D = 1.0

F = 0.0

Here are some Common Universities who are Using This Method Harvard University, Massachusetts Institute of Technology, Stanford University, University of California, Berkeley

2. European Universities 

European universities also use a 4-point scale, where grades are multiplied by credit hours and then divided by the total credit hours.

Grade Points Mapping on 4 scale:

A = 4.0 (Excellent)

B = 3.0 (Good)

C = 2.0 (Satisfactory)

D = 1.0 (Pass)

F = 0.0 (Fail)

Here are Some common Universities who Use same Methods are Oxford University (UK), University of Cambridge (UK), ETH Zurich (Switzerland), University of Amsterdam (Netherlands)

3. Australian Universities

This formula is similar to other systems but uses different grade point scales based on the institution. Universities may convert grades to a common scale (usually 7-point or 4-point).

Some Common universities that use this method are the University of Melbourne, the University of Sydney, and the Australian National University (ANU).

Grade Points Mapping on a 7 Scale Point: 

7= High Distinction 

6 = Distinction 

5 = Credit

 4 = Pass

0 = Fail 

Australian institutions differentiate between graded and non-graded courses in their GPA/OGPA calculation. Some universities may provide prerequisite courses for final OGPA calculation.

4. Asian and Middle Eastern Universities

OGPA Calculation Formula is Similar to the 4-point or 5-point scale methods used in the US or Europe.

Some Common Universities who Use This Method are National University of Singapore (NUS), King Saud University (Saudi Arabia), University of Tokyo (Japan), Khalifa University (UAE)

Grade Points Mapping:

• A = 4.0
• B = 3.0
• C = 2.0
• D = 1.0
• F = 0.0

Many universities in Asia and the Middle East follow the Western grading systems (4-point or 5-point), but they have local variations in course weightage and credit hour assignment.

5. Canadian Universities

OGPA Calculation Formula Is Similar to the 4-point scale used in the US. Some institutions may also use a percentage in conjunction with the 4-point scale.

Some Common Universities Using This Method are University of Toronto, McGill University ,University of British Columbia (UBC)

Grade Points Mapping (4-point scale):

• A+ = 4.0
• A = 4.0
• B+ = 3.5
• B = 3.0
• C+ = 2.5
• C = 2.0
• D = 1.0
• F = 0.0

Canadian universities often use a weighted credit hour system to calculate OGPA. Some graduate programs might use a slightly different scale or calculation method for OGPA.
