What is NU CGPA?
Understanding the NU Grading System & Credit Structure.
The NU CGPA (Cumulative Grade Point Average) is a summary metric that reflects a student’s performance across all courses taken up to a particular point in their degree program. Unlike simple averaging, the NU grading system employs a credit-weighted grade calculation to ensure courses with higher academic load (more credits) have a proportionally greater impact on the final result.
This system adheres to the standard academic practice where:
- Grade Point: A numeric value (typically 0.00 to 4.00) assigned to a letter grade (e.g., A, B, C).
- Credit Hour: The academic weight assigned to a specific course. A 4-credit course, for instance, holds twice the weight of a 2-credit course.
- CGPA: The final, weighted average calculated from all courses’ grade points and credit hours.
Understanding these three components is the foundation for using any reliable CGPA calculator NU.
The Official National University Grading System
The National University grading system follows a standardized Grade Point system out of 4.00. This table is crucial for students asking how to calculate CGPA out of 4 and is the engine behind every accurate NU CGPA Calculator.
NU Grade-to-Point Conversion Chart:
Letter Grade | Grade Point (GP) | Numerical Marks (%) | Academic Standing |
A+ | 4.00 | 80 and above | First Class |
A | 3.75 | 75 to less than 80 | First Class |
A- | 3.50 | 70 to less than 75 | First Class |
B+ | 3.25 | 65 to less than 70 | First Class |
B | 3.00 | 60 to less than 65 | First Class |
B- | 2.75 | 55 to less than 60 | Second Class |
C+ | 2.50 | 50 to less than 55 | Second Class |
C | 2.25 | 45 to less than 50 | Second Class |
D | 2.00 | 40 to less than 45 | Pass |
F | 0.00 | Less than 40 | Fail (Must Retake) |
Academic Note: While this table represents the most common NU grading system, specific departments or affiliated colleges may have minor variations in grading policies, especially concerning numerical marks or standing classifications. Always cross-reference with your official college/department documentation.
How to Count CGPA – Step-by-Step (The Official NU Method)
The key to manually checking the result from your NU CGPA Calculator is mastering the credit-weighted calculation. This is the standard procedure for all NU Honours, Degree, and Masters results.
The Credit-Weighted Formula Explanation
The fundamental formula for calculating both Semester GPA (SGPA) and the final NU CGPA is:
Or, more formally:
Example 1: Basic Semester CGPA Calculation.
Let’s apply this formula to a single semester to find the SGPA (Semester Grade Point Average), which is the first step toward calculating the final NU CGPA.
| Course Name | Credit Hours (C) | Letter Grade | Grade Point (GP) | C×GP (Weighted Points) |
| Course A | 4 | A- | 3.50 | 4 \times 3.50 = 14.00 |
| Course B | 4 | B | 3.00 | 4 \times 3.00 = 12.00 |
| Course C | 2 | A+ | 4.00 | 2 \times 4.00 = 8.00 |
| Course D | 4 | C+ | 2.50 | 4 \times 2.50 = 10.00 |
| Totals | C = 14 | C × GP = 44.00 |
Calculation:
The Semester GPA (SGPA) for this student is 3.14.
Example 2: Multiple Semesters with Variable Credits
The final NU CGPA is simply the weighted average of all courses from all completed semesters, including both failed/retaken courses (the most recent grade/point applies) and passed courses.
Semester | Total Credit Hours Taken (C) | Semester GPA (SGPA) | Total Weighted Points Earned (C×GP) |
1st Semester | 18 | 3.14 | 18 × 3.14 = 56.52 |
2nd Semester | 20 | 3.25 | 20 × 3.25 = 65.00 |
3rd Semester | 22 | 3.50 | 22 × 3.50 = 77.00 |
Totals | CCumulative = 60 | C × GP Cumulative = 198.52 |
Final CGPA Calculation:
CGPA = 198.52 ÷ 60 ≈ 3.308
The cumulative NU CGPA after three semesters is approximately 3.31. This is the exact logic employed by a multi-semester semester CGPA calculator tool.
Semester GPA (SGPA) → Final NU CGPA
The journey to the final result starts with the SGPA and culminates in the NU CGPA.
- SGPA: This is the Grade Point Average for a single academic semester.
- CGPA: This is the cumulative average of all courses taken from the first semester up to the current one. It is the metric used for final degree classification.
A proper NU result calculator will allow you to input each semester’s courses or the SGPA and total credits to determine the final CGPA.
How to Calculate CGPA Out of 4
When students ask how to calculate CGPA out of 4, they are referring to the scale used by the National University grading system. The “out of 4” signifies that the highest achievable Grade Point is 4.00 (an A+ with marks 80% and above).
The NU system is inherently a 4-point scale system. Your final NU CGPA will always fall between 0.00 and 4.00. Any reliable CGPA calculator NU must reflect this maximum limit.
Common Mistakes NU Students Make
- Ignoring Credit Weight: A common error is simply averaging the Grade Points without multiplying by the credit hours. This results in a mathematically incorrect, unweighted GPA.
- Misinterpreting Grade Points: Using an incorrect grade point (e.g., mistaking 3.75 for 3.50) can significantly alter the result. Always refer to the official NU table.
- Excluding Failed Courses: In the NU grading system, all courses taken, including those with an ‘F’ grade (which is 0.00 Grade Point), must be included in the cumulative calculation until they are retaken and passed.

How to use the CGPA calculator
The National University CGPA Calculator is designed to simplify complex credit-weighted calculations, whether you input course-by-course or use your prior term GPAs.
Method 1: Calculate From Yearly GPAs (Recommended For Quick Checks)
- Navigate to the CGPA Calculator tab and select “Calculate from Yearly GPAs.”
- Year 1 Input: Enter your Year/Semester GPA (e.g., 3.50) and the Total Credits awarded for that year/term (e.g., 22).
- Year 2/3/4 Input: Add rows using “Add Another Year/Semester” and repeat the process for all terms/years of your program.
- Final Step: Click Calculate CGPA. The tool uses the CGPA formula above to credit-weight your term GPAs.
Method 2: Calculate From Individual Courses (Recommended For Maximum Precision)
- Navigate to the CGPA Calculator tab and select “Calculate from Individual Courses (Overall).”
- Course Entry: For every single course taken in your degree (mandatory for accuracy):
- Enter the Course Name (Optional, e.g., Bangla).
- Select the Input Type (Points, Grade, or Marks).
- Enter the corresponding score (e.g., Grade B+ or Marks 68).
- Enter the Credit Hours (e.g., 4).
- Consistency Check: Ensure the total number of credits entered matches the total credit load of your program (e.g., 140 for Honours).
- Final Step: Click Calculate CGPA. This method is the most precise as it directly applies the grade point to the credit hour for every paper, mirroring the official university process.
NU Result CGPA vs. CGPA Calculator BD Tools
It is vital to distinguish between your official NU result CGPA and the result from any third-party CGPA calculator BD.
- Official NU Result CGPA: This is the final, recorded, and verifiable result printed on your official transcript issued by the National University. This result is the only one used for job applications, further studies, and degree classification.
- Third-Party Calculator: A tool like our NU CGPA Calculator is an estimation and an academic aid. It helps you track your progress, anticipate your result, and understand how to count CGPA manually. It should never be treated as the final authority.
If there is a discrepancy between a calculator’s output and your official NU result CGPA transcript, the official transcript is always correct.
Honours CGPA Calculator – How It Works for NU Students
The four-year Honours program at NU requires a total of 120 to 140 (approximate) credit hours and spans eight semesters. The structure for the Honours CGPA calculator is identical to the general formula but demands careful cumulative input over the entire degree.
The key distinction for the Honours CGPA system is the emphasis on maintaining the minimum passing CGPA (2.00 typically) throughout all four years and the high cumulative credit load. A good Honours CGPA calculator should allow the input of many courses or multiple semester results to provide a long-term projection of your final degree class.
Worked Example: Honours 4-Year CGPA Scenario
Let’s illustrate the CGPA calculation for an Honours student based on the Yearly GPAs input method.
| Term/Year | Term GPA | Term Total Credits | Calculation: (GPA×Credits) |
| Year 1 | 3.5 | 22 | 3.50×22=77.00 |
| Year 2 | 3.12 | 25 | 3.12×25=78.00 |
| Year 3 | 3.25 | 20 | 3.25×20=65.00 |
| Totals | – | Total Credits: 67 | Total Grade Points: 220.00 |
CGPA Calculation:
The result of 3.28 translates to a First Class degree, confirming the tool’s output based on NU’s policy.

Semester CGPA Calculator (For Multi-Semester NU Input)
A semester CGPA calculator is a specialized tool that either:
- Calculates the SGPA for a single semester (like Example 1).
- Aggregates the total weighted points and total credits from all previous semesters to give the overall cumulative NU CGPA.
This is the most direct way to check your progress immediately after receiving your NU result CGPA for a single semester.
NU CGPA to Percentage Conversion
The National University grading system primarily uses the 4.00 CGPA scale. While many students need to convert their NU CGPA to a percentage for various applications, a universal, officially mandated conversion formula is often difficult to verify across all NU departments and degree types.
A Safe, Non-Speculative Approach: For general academic guidance and comparison, a widely used, but unofficial, conversion method involves a simple multiplication. However, for official purposes, always rely on:
- The Official Transcript: The transcript itself sometimes provides a percentage equivalent.
- Official Application Requirements: Use the conversion formula specified by the scholarship, university, or job application you are applying to.
Crucially, do not rely on an unsubstantiated conversion formula from any CGPA calculator unless it explicitly cites an official NU policy.

Frequently Asked Questions (FAQs)
You calculate CGPA manually by summing the product of (Credit Hours × Grade Point) for all courses and dividing that sum by the total credit hours taken. This is the official credit-weighted method.
The NU grading system is already a 4-point scale. The calculation process involves assigning Grade Points (0.00 to 4.00) to your letter grades and then using the credit-weighted formula. Your final NU CGPA is your result "out of 4".
The National University grading system is a 4.00 scale system that uses letter grades (A+, A, B, C, D, F) corresponding to specific Grade Points (4.00 to 0.00) and numerical mark ranges.
A semester CGPA calculator is used to determine the SGPA (Semester GPA) for a single academic period or to combine multiple semester results to find the cumulative NU CGPA.
An Honours CGPA calculator works by applying the standard credit-weighted formula to the entire set of courses taken over the four-year Honours program to determine the final degree CGPA.
SGPA is the Grade Point Average for one semester, while NU CGPA is the cumulative, weighted average of all semesters completed in the program.
A good CGPA calculator BD tool is reliable as an estimation aid, provided it uses the correct, official National University grading system and credit-weighted formula. However, only your official NU transcript provides the final, legally binding NU result CGPA.
Yes, you can use an NU result calculator to estimate your result if you know your individual course letter grades and credit hours before the official publication of your NU result CGPA.
The minimum passing grade is generally D, corresponding to 2.00 Grade Point, though rules can vary. Students must maintain a cumulative NU CGPA above the minimum passing threshold to graduate.
The credit-weighted system ensures that courses that demand more study time (higher credit hours) have a greater, proportional impact on your overall academic result.
