CPI to Percentage

The nature and types of grading system in India vary from alphabetical to numerical to a mix of both. Consequently, students face huge difficulties while comparing the scores to other different implemented standards in India as well as while applying to study abroad (which is a whole another obstacle). Furthermore, one needs to be well-versed with the terms used as well as conversion methods employed in order to avoid any chance of discrepancy that might creep during the application process. For admission and career-related purposes, students feel the need to convert their CGPA, SGPA, SPI to percentage terms. Through this blog, we will explore the key essentials of converting Cumulative Performance Index or CPI to percentage.

CPI to Percentage: Factors Involved

While calculating grades or percentage of a student, the university takes into account various factors such as the concerned discipline, the nature of the degree like master’s or PhD, the length of the course, practicals, credit structure, amongst others. Further, when it comes to the conversion of different grading systems into percentage, Engineering and Science-related universities or departments may implement slightly varying approaches than that employed elsewhere. Let’s take a look at the major factors that you need to keep in mind while converting CPI to percentage.

Semester or Annual-Based

Though the semester-based system is universally applied, the annual-based system is still practised in more than a handful of universities, particularly in distance and open courses. Before understanding how CPI to percentage conversion works, you should consider the evaluation system used by the institutions of the particular country. Generally, the semester system divides the academic year into six to eight equal parts of study sessions in a three to four-year program. For example, in India, a three-year Bachelor of Management Studies or BBA in Airport Management program consists of 6 semesters while a four-year B.Tech in various engineering branches comprises of 8 semesters. 

Credit Structure

Bringing a much-needed alternative to approaches like CPI to percentage, the credit structure has been utilised by many academic institutions across the globe. Typically, the structure of the course involves scoring on the basis of credits for compulsory, core and elective courses. Moreover, credits also depend on the number of hours of instructional study per week. For a compulsory subject, higher credits might be required as compared to the credits needed for language or additional courses. The newly-implemented choice-based credit system wherein students can pursue one or two subjects in any department of the university is a significant step to diversify the rigid structure usually implemented in India.

Grading System

The currently heavily practised 10-pointer scale is only one of the methods of grading system which has variants such as 8-pointer system, 9-pointer system and AP-pointer system amongst others. Further, universities in USA practise the 4-point system and UK institutions implement the ‘2-point class honours’ system.

Cumulative Performance Index (CPI)

The CPI is a measure of the candidate’s overall performance in all the subjects studied according to the number of credits each discipline entails. Usually, it is aggregated at the end of every semester and includes the grades obtained until the time of calculation. Further, you can convert CPI to percentage as well as grade points, whichever the institution you are applying to is asking for.

The formula for calculation of CPI is:

CPI = (C1*g1 + C2*g2 + C3*g3 + C4*g4+…. +Cn*gn) / C1 + C2 + C3 + C4+….+Cn

C= credits

g= grades obtained

Note: This process of calculation shall concern ‘n’ subjects taken up to ‘r’ semesters. If the student fails in a subject, the ‘g’ will be taken as ‘0’.

Before elaborating the formula of CPI to percentage, let’s take a look at how the grade points can be calculated using credits with the help of the following table:

SubjectsGrade Point ‘g’ (out of 10)Credits (C)Grade*Credit (Cn*gn)
Subject 19436
Subject 27428
Subject 38432
Subject 47428
Subject 56212
Total3718136

CPI= Sum of Grade*Credit/Total Credit = 130/18=7.55

CPI to Percentage: Major Approaches

There are two prevalent methods used for the conversion of CPI to Percentage which have been mentioned below.

1. Direct Conversion 

The method of direct conversion of CPI to percentage is typically used by engineering institutes for facilitating the admission process of B.Tech/B.Arch degrees.

Percentage= CPI*10

Example: If CPI is 7.55, the percentage is 75.5

Note: This technique of calculation is generally followed by IITs. Check out the CPI to percentage approach used by the IIT Bombay’s here.

2. Formula Method

To obtain equivalence from CPI to percentage, the formula method requires you to calculate:

Percentage= (CPI – 0.5) * 10

If the CPI is 7.55, the percentage equals (7.55-0.5)*10 which in turn gives 70.5.

Note: In some cases, CPI to percentage is calculated only for two-year courses and CGPA is concerned with four-year courses.
