What Is the IIT Kharagpur Grading System?
IIT Kharagpur’s grading system runs on a 10-point scale with 7 letter grades: EX, A, B, C, D, P, and F. Each letter maps to a fixed grade point between 0 and 10. The system uses credit-based performance evaluation, meaning a 4-credit course carries four times the weight of a 1-credit course when calculating your CGPA.
The institute follows the credit-based system outlined in its official UG Rules and Regulations. Every registered subject carries a specific number of credits, and those credits act as weights in the CGPA formula. Think of it like a weighted average in finance — a large position moves the portfolio more than a small one.
This structure means a poor grade in a 5-credit core subject damages your CGPA far more than the same grade in a 1-credit elective. Students who understand this plan their semester load accordingly. The credit system also directly affects how your CGPA converts to a percentage when you apply for placements or postgraduate admissions.
What Are the Letter Grades and Grade Points at IIT KGP?
IIT Kharagpur uses the following official grade table for all undergraduate and postgraduate programs:
Letter Grade | Grade Point | Performance Level | Approximate Marks Range |
EX | 10 | Excellent | 90 – 100 |
A | 9 | Very Good | 80 – 89.99 |
B | 8 | Good | 70 – 79.99 |
C | 7 | Fair | 60 – 69.99 |
D | 6 | Average | 50 – 59.99 |
P | 5 | Pass | 40 – 49.99 |
F | 0 | Fail | 0 – 39.99 |
One critical point: the marks ranges above show approximate absolute thresholds. IIT KGP applies relative grading in most courses, which means the professor sets the actual grade boundaries based on class performance, average scores, and standard deviation. A student scoring 82 in one batch may get an A, while the same score in a higher-performing batch may yield a B.
Non-credit courses (such as National Sports Organisation or NCC) receive Satisfactory (S) or Unsatisfactory (U) grades. These grades do not enter the SGPA or CGPA calculation.
How Does Relative Grading Work at IIT KGP?
Relative grading at IIT KGP means the letter grade boundaries shift based on the class performance in each course. The professor fixes the distribution — typically 10-15% of students receive A or EX, 20-35% receive B or C, and the lowest performers receive D or P — so scoring 90 marks does not guarantee an EX if the class average itself is high.
This is the most misunderstood aspect of the IIT KGP grading system. Students arrive expecting that 90% always equals EX. It does not. The professor uses statistical methods to set cutoffs after seeing the full class score distribution.
The practical implication: two students with identical raw marks but in different course sections can receive different letter grades. This makes peer comparison on raw marks unreliable. Your grade reflects where you stand relative to your cohort, not against a fixed marking key.
How Is SGPA Calculated at IIT Kharagpur?
SGPA (Semester Grade Point Average) measures your performance in a single semester. IIT KGP calculates it using this formula:
SGPA = Σ (Credit of Subject × Grade Point Earned) ÷ Σ (Credits of All Subjects in Semester)
Worked Example — Semester 3
Subject | Credits (C) | Grade | Grade Points (G) | C × G |
Mathematics III | 4 | A | 9 | 36 |
Data Structures | 4 | EX | 10 | 40 |
Electronics | 3 | B | 8 | 24 |
Thermodynamics | 3 | C | 7 | 21 |
Lab: Programming | 2 | A | 9 | 18 |
Total | 16 | 139 |
SGPA = 139 ÷ 16 = 8.69
Now add a failed subject to see the impact:
Subject | Credits (C) | Grade | Grade Points (G) | C × G |
Same 5 above | 16 | (as above) | 139 | |
Elective | 3 | F | 0 | 0 |
Total | 19 | 139 |
SGPA = 139 ÷ 19 = 7.32
One failed 3-credit elective drops the semester SGPA from 8.69 to 7.32. SGPA covers one semester only and must never be submitted where CGPA is required. You can use the SGPA to percentage calculator to convert any semester score instantly.
How Is CGPA Calculated at IIT Kharagpur?
CGPA (Cumulative Grade Point Average) measures your total academic performance across all completed semesters. IIT KGP uses this formula:
CGPA = Σ (Credit of Every Subject × Grade Point Earned, across all semesters) ÷ Σ (Total Credits across all semesters)
Worked Example — 3 Semesters
Semester | SGPA | Credits That Semester | Weighted Points |
Semester 1 | 8.50 | 18 | 153 |
Semester 2 | 7.80 | 20 | 156 |
Semester 3 | 8.69 | 16 | 139 |
Total | 54 | 448 |
CGPA = 448 ÷ 54 = 8.30
Notice that Semester 2, carrying 20 credits, pulls more weight than Semester 3 at 16 credits. A heavier semester moves your CGPA more. This matters during academic planning — a strong performance in a credit-heavy semester improves CGPA faster than the same performance in a lighter one.
The SGPA to CGPA calculator lets you aggregate semester scores into a running cumulative average without manual calculation.
How Do You Convert IIT Kharagpur CGPA to Percentage?
IIT Kharagpur’s official CGPA to percentage conversion formula is: Percentage = CGPA × 10. A student with an 8.3 CGPA holds an equivalent percentage of 83%. This formula appears directly on IIT KGP grade transcripts and is the figure accepted by employers, government job applications, and foreign universities.
CGPA | Percentage | Degree Classification |
10.0 | 100% | Outstanding |
9.5 | 95% | First Class with Distinction |
9.0 | 90% | First Class with Distinction |
8.5 | 85% | First Class with Distinction |
8.0 | 80% | First Class |
7.5 | 75% | First Class |
7.0 | 70% | First Class |
6.5 | 65% | Second Class |
6.0 | 60% | Second Class |
5.5 | 55% | Pass Class |
5.0 | 50% | Pass Class |
Unlike CBSE, which uses CGPA × 9.5, IIT KGP uses a straight ×10 multiplier. A 10.0 CGPA at IIT KGP converts to 100%, not 95%. This differs from the standard Indian board formula — applying the CBSE multiplier to an IIT KGP transcript gives a wrong, lower figure.
The CGPA to percentage calculator on this platform applies the IIT KGP-specific ×10 formula when you select the IIT scale, so your output matches what’s printed on your official transcript.
What Is the Minimum CGPA to Pass at IIT Kharagpur?
Students at IIT Kharagpur must earn at least a P grade (5 grade points) in every registered course and maintain a minimum CGPA of 6.00 across all semesters to qualify for degree award. Falling below 6.00 CGPA puts a student’s degree completion at risk and triggers academic probation under institute rules.
Every course requires clearing the minimum internal and external marks thresholds separately. Passing the end-semester exam alone does not guarantee a pass grade if internal marks push the combined score below the P threshold.
Students who receive an F must re-register for that course in a subsequent semester. The F grade remains in the calculation with 0 grade points until the course is re-taken and a passing grade replaces it. Understanding the 10-point grading scale helps you track exactly where each grade sits on the performance spectrum.
How Does IIT KGP CGPA Affect Placements and Higher Studies?
CGPA at IIT KGP directly sets your placement eligibility. Most top-tier companies — consulting firms, investment banks, and product-based tech firms — require a minimum CGPA of 7.0 to 8.0 for shortlisting. Core engineering firms typically set the bar at 6.5. Government PSU recruiting through GATE often requires a minimum of 60% equivalent, which translates to 6.0 CGPA under the ×10 formula.
For foreign university applications, admissions committees request your CGPA alongside a percentage equivalent. The cumulative grade point average page explains how international evaluators like WES interpret Indian CGPA on foreign applications.
Always submit your official transcript’s CGPA value — not your SGPA — for every formal application. Use the CGPA calculator to verify your running CGPA before applying to any program or placement drive.
Frequently Asked Questions About IIT KGP Grading
What is the most common grading mistake IIT KGP students make?
The most common error is treating approximate marks ranges as fixed grade boundaries. IIT KGP uses relative grading, so the thresholds shift by course cohort. Assuming 80% always gives an A can misguide semester planning.
Does a 10.0 CGPA equal 100% at IIT Kharagpur?
Yes, at IIT KGP it does. The conversion formula is CGPA × 10, so a perfect 10.0 CGPA equals 100%. This differs from CBSE, where the ×9.5 formula caps a 10.0 CGPA at 95%.
How does an F grade affect final CGPA classification?
An F grade contributes 0 grade points and is included in the CGPA denominator. It pulls down the cumulative average until the course is re-registered and a passing grade replaces it. Backlogs can prevent a student from reaching 7.0 CGPA for distinction-level classification.
Does the grading scale apply to M.Tech and MBA programs too?
Yes. IIT KGP applies the same 10-point letter grade system — EX through F — across B.Tech, Dual Degree, M.Tech, MBA, and PhD programs. The credit weights differ by program, but the grade point values remain identical.
Where do students get an official percentage certificate from IIT KGP?
The official percentage equivalent appears on your grade transcript issued by the Examination Section, IIT Kharagpur. Download it from the ERP portal at erp.iitkgp.ac.in. Self-calculated figures are not accepted for government job applications or formal credential evaluations.
IIT Kharagpur’s ×10 conversion formula makes the math straightforward — your CGPA multiplied by 10 gives your official percentage. Use the CGPA to percentage calculator to confirm your figure against the exact IIT KGP formula before submitting any application.
