So, you’ve been checking your semester results, and now you need to know your Cumulative Grade Point Average (CGPA) on a 5.0 scale. Whether you’re studying at a Nigerian university or any institution using the 5.0 grading system, knowing how to calculate CGPA is essential.
Your CGPA determines your academic standing, including whether you graduate with First Class, Second Class Upper, Second Class Lower, or Third Class.

🎯 What is the 5.0 Grading Scale?
Unlike the 4.0 scale (used in most polytechnics), universities in Nigeria generally use a 5.0 grading system. The highest CGPA is 5.00, meaning an A grade equals 5.0 points instead of 4.0.
Standard 5.0 Grading System in Nigerian Universities
| Score (%) | Grade | Grade Point (GP) |
|---|---|---|
| 70 – 100 | A | 5.0 |
| 60 – 69 | B | 4.0 |
| 50 – 59 | C | 3.0 |
| 45 – 49 | D | 2.0 |
| 40 – 44 | E | 1.0 |
| 0 – 39 | F | 0.0 (Fail) |
🏆 Step-by-Step Guide to Calculating CGPA on a 5.0 Scale
Step 1: Understand Key Terms
- Credit Unit (CU): The weight of a course (e.g., a 3 CU course has more impact than a 2 CU course).
- Grade Point (GP): The numeric value assigned to each grade (A = 5.0, B = 4.0, etc.).
- Quality Point (QP): This is Credit Unit × Grade Point for each course.
- GPA (Grade Point Average): The average performance in a single semester.
- CGPA (Cumulative Grade Point Average): The average performance across multiple semesters.
Step 2: Calculate GPA for Each Semester
To determine your GPA for a semester:
Example of GPA Calculation for a Semester
| Course | Credit Unit (CU) | Grade | Grade Point (GP) | Quality Point (QP) (CU × GP) |
|---|---|---|---|---|
| MTH 101 | 3 | A | 5.0 | 3 × 5.0 = 15 |
| ENG 102 | 2 | B | 4.0 | 2 × 4.0 = 8 |
| PHY 103 | 3 | C | 3.0 | 3 × 3.0 = 9 |
| BIO 104 | 2 | D | 2.0 | 2 × 2.0 = 4 |
Total Quality Points (TQP) = 15 + 8 + 9 + 4 = 36
Total Credit Units (TCU) = 3 + 2 + 3 + 2 = 10
Step 3: Calculate CGPA Over Multiple Semesters
To determine your CGPA across all semesters:
Example of CGPA Calculation Over 4 Semesters
| Semester | GPA | Total Credit Units (TCU) |
|---|---|---|
| 1st | 3.6 | 10 |
| 2nd | 3.2 | 12 |
| 3rd | 3.8 | 11 |
| 4th | 3.5 | 12 |
Total Quality Points (TQP) =
(3.6 × 10) + (3.2 × 12) + (3.8 × 11) + (3.5 × 12)
= 36 + 38.4 + 41.8 + 42
= 158.2
Total Credit Units (TCU) = 10 + 12 + 11 + 12 = 45
✅ Final CGPA = 3.52 (Second Class Upper)

💡 Important Notes:
- Most Nigerian universities require at least a 2.50 CGPA for postgraduate studies or job applications.
- A CGPA below 1.50 may result in withdrawal from the program.
🚀 Tips to Improve Your CGPA on a 5.0 Scale
