The CAT composite score is calculated based on the weighted average of your normalised CAT score plus other factors like 10th, 12th, Graduation marks, Work experience and Diversity. Each IIM assigns different weightages to these components for selection, which makes it unique to each institute.
Breakdown of the calculation:
- Raw score to Scaled score through Normalisation process for each section
- Scaled score of all three sections added to get your overall scaled score
- Each IIMs have different weights around 30-40% to your sccaled CAT score, 10th and 12th Marks, Work experience and Diversity factors.
So, the final CAT composite score is calculated by the following formula:
| (CAT Score * Weight) + (10th Marks * Weight) + (12th Marks * Weight) + (UG Marks * Weight) + (Work Ex * Weight) + (Diversity * Weight). |

Key Summary
- Each IIM uses its own composite formula combining CAT percentile, academics, and work experience.
- Academic weightage is higher at IIM Kozhikode and Indore, while CAT dominates Calcutta and Lucknow.
- Work experience carries 5-10% weightage, mainly for candidates with 24–36 months of experience.
- Gender and academic diversity can add 2-10%, benefiting non-engineers and female candidates.
How B-Schools Use Composite Scores?
As per the official admission policies of different B-Schools, they use a composite score to evaluate candidates on the basis of overall aspects. Multiple aspects like CAT score, academic profile, work experience, diversity factors and PI/WAT performance.
- Different B-Schools have different weightage ranges for each aspect.
- These institutes shortlist candidates based on a composite score rather than only based on the CAT score.
This gives a fair chance to the candidates with good academic records and relevant work experience, even if their CAT score is lower for any reason
| Component | Typical Weightage Range |
|---|---|
| CAT Score | 50-70% |
| Academic Profile | 10-30% |
| Work Experience | 0-15% |
| Diversity Factors | 0-10% |
| PI/WAT Performance | 20-40% (final selection) |

Ques. Is the composite score the same as the CAT percentile?
Ans: No, the composite score is not the same as the CAT percentile. It is a mix of CAT percentile and academics, work experience, diversity factors, and interview performance. All aspects are assigned a certain weightage in the calculation.
Ques. Do all IIMs use the same composite formula?
Ans: No, each IIM has unique weightages. Some prioritise CAT scores while others give more importance to academics or diversity.
Calculating the CAT Score Component
The CAT percentile is scaled to a normalised score, which is normally out of 100 or a given number of points. Note that different IIMs use different conversion methods.
To understand this, let's take an example.
Assume that CAT weighs 60% for one of the IIMs.
If you have scored 98 percentile, then as per the calculation, your CAT composite score for that IIM will be 98x 0.50 =49/50 points.
So by this formula, the higher your percentile, the higher the marks you will get.
| CAT Percentile | Points (50% Weightage) | Points (70% Weightage) |
|---|---|---|
| 99+ | 49.5+ | 69.3+ |
| 95- 99 | 47.5- 49.5 | 66.5- 69.3 |
| 90- 95 | 45.0- 47.5 | 63.0- 66.5 |
| 85- 90 | 42.5- 45.0 | 59.5- 63.0 |
| 80- 85 | 40.0- 42.5 | 56.0- 59.5 |
Ques. Does sectional percentile affect composite score?
Ans: Yes, Sectional performance directly affects the composite score. It's because your raw marks in each section are basically first normalised based on different slots. Then these section-wise sealed scores are added to determine your composite score.
Ques. Can I compensate low CAT score with academics?
Ans: Partially yes, but CAT carries maximum weight (50-70%). Excellent academics help, but cannot fully offset significantly lower CAT percentiles.
Calculating Academic Profile Component
- The academic profile has three sections: Class 10, Class 12 and graduation scores.
- All IIMs standardise these scores on a 10-point scale. Then, they assign specific weightages to each.
- Typically, the academic component contributes 10-30% to your composite score.
You need to calculate each academic level separately first. After that, combine them based on sub-weightages. For example, suppose academics carry 20% total weight with equal distribution. So, every level will be assigned about 6.67% weightage in the final composite score.
| Academic Level | Sample Score | Sub-Weightage | Contribution to Composite |
|---|---|---|---|
| Class 10 (85%) | 8.5 / 10 | 6.67% | 0.57 |
| Class 12 (80%) | 8.0 / 10 | 6.67% | 0.53 |
| Graduation (75%) | 7.5 / 10 | 6.67% | 0.50 |
| Total Academic Component | — | 20% | 1.60 |

Ques: What does a 9 9 8 profile mean?
Ans: 9 9 8 profile means a student has scored 90+% in 10th and 12th and 80+% in graduation. So basically, anyone scoring between 90-99 will be in 9 categories, and from 80-89 it will be in 8 categories.
Calculating Work Experience Component
Work experience can add 0-15% to your composite score, depending on the B-school.
- Some IIMs, like Ahmedabad, give significant weightage, while others, like Bangalore, give none for shortlisting but consider it during interviews.
- Ideal work experience ranges from 0-36 months for most IIMs.
- The calculation often follows a bell curve, with maximum points awarded for 24-36 months of experience.
| Work Experience | Typical Points (10% Weightage) |
|---|---|
| 0–12 months | 3- 5 |
| 13–24 months | 6- 8 |
| 25–36 months | 9- 10 |
| 37–48 months | 6- 8 |
| 49+ months | 3- 5 |

Ques. Do freshers have a disadvantage in composite scores?
Ans. No, different IIMs have different preferences. IIMs, such as Ahmedabad, prefer applicants who have work experience. Meanwhile, some are fresher-friendly, such as Bangalore and Baby IIMs.
Ques. Does work experience quality matter or just duration?
Ans. For composite score calculation, primarily, duration matters. Quality and relevance are evaluated separately during personal interviews for final selection.
Understanding Diversity Factors
- Diversity factors include gender (mainly female candidates), academic background (non-engineers), and sometimes state or category diversity.
- These typically contribute 2-10% to composite scores, varying significantly across B-schools.
- Female candidates often receive 2-5 bonus points to promote gender diversity. Non-engineering graduates may get additional points at some IIMs.
Check: CAT Diversity at IIM: Benefits for Non-Engineers and Female candidates
| Diversity Factor | Typical Bonus Points |
|---|---|
| Female Candidate | 2 - 5 points |
| Non-Engineering Graduate | 0 - 3 points |
| Academic Diversity (Arts / Commerce) | 0 - 2 points |
| Geographic Diversity | 0 - 2 points |

Ques. Do diversity points guarantee admission?
Ans. No, they only improve your composite score slightly. You still need competitive CAT scores and strong overall performance.
Ques. Are engineers at a disadvantage due to diversity factors?
Ans. No, really, it’s the minimal disadvantage. Engineers form the majority of candidates, so slight diversity points for Non-Engineering Graduate balance the equation without significantly affecting engineering graduates.
Composite Score Calculation Example:
Let's take an example:
An IIM follows the below final composite score weightage:
- CAT Score: 60%
- Academic Profile ( 10th + 12th + Graduation): 20%
- Work Experience: 10%
- Diversity ( Gender / Academic): 10%
- Total: 100%
CAT Score Contribution:
Let's say the candidate has around 95 percentile, so the CAT Composite score will be:
CAT Composite Score = 95 * 0.60 = 57.00
Academic Profile Contribution:
From the above-mentioned academic calculation example:
- Standardized academic score = 1.60
- Maximum possible academic score = 2.00
- Academic weightage = 20%
Academic Contribution = (Standardized Score ÷ Maximum Score) × Weightage = (1.60 ÷ 2.00) × 20 = 16.00
Work Experience Contribution
Let's say the candidate has 30 months of experience, so it will be 8 out of 10 points.
So Work experience composite score = (8 ÷ 10) × 10 = 8.00
Diversity Contribution
Assume the candidate receives 5 out of 10 diversity points.
So Diversity composite score = (5 ÷ 10) × 10 = 5.00
Final Composite Score Calculation
| Component | Score |
|---|---|
| CAT Score | 57.00 |
| Academics | 16.00 |
| Work Experience | 8.00 |
| Diversity | 5.00 |
| Final Composite Score | 86.00 / 100 |

What Reddit Users Say About Composite Scores
One Reddit user shared scoring 96 percentile with strong academics (85%+ throughout) and receiving multiple old IIM calls, while another with 98 percentile but weaker academics (65-70%) received fewer calls.
This highlights how composite scores balance different components.
| Reddit Insight | Key Learning |
|---|---|
| Check individual IIM websites | Each IIM publishes its exact composite score weightage annually |
| Calculate multiple scenarios | Helps identify which IIMs best suit your academic and work profile |
| Don’t obsess over decimals | Composite scores are evaluated in ranges, not exact point values |
| Focus on controllable factors | GD/PI often carries 30-40% weight in the final selection |
Note: Reddit users also caution against "analysis paralysis" – spending too much time calculating scores instead of preparing for interviews. Once shortlisted, interview performance matters most.
Check: Which IIM does Not Consider Work Experience
Ques. Should I calculate the composite for every B-school?
Ans: Focus on your top 10-15 target schools instead. Most IIMs publish their formulas on official websites. This makes calculations straightforward with basic spreadsheet skills.
Ques. When do composite scores matter most?
Ans: Composite scores matter at two crucial stages. First, during the shortlisting stage, they decide on interview calls. Second, during the final selection stage, they decide on admission offers.
So to sum up, calculating your composite score will allow you to have realistic expectations on the B-school admissions. The formula does not look easy at first. However, breaking it into individual components makes it manageable.
Remember that composite scores determine shortlisting decisions. Nevertheless, interview performance significantly impacts final selection.
When you get calls, concentrate on preparation before personal interviews. Your interview has the ability to either break or make your admission chances, regardless of the composite score.
