Nigerian University CGPA Calculator (5.0)
Nigerian universities grade on the 5-point scale set by the National Universities Commission. The Core Curriculum and Minimum Academic Standards (CCMAS) 2023 repeat it in every discipline document: 70–100 is A (5), 60–69 B (4), 50–59 C (3), 45–49 D (2), 40–44 E (1) and 0–39 F (0). Your GPA is the total of units × grade points (TUGP) divided by the total number of units (TNU) you took in the semester; the CGPA is the same division over every course taken so far.
The class of degree comes straight from the CGPA, to two decimals: 4.50–5.00 First Class Honours, 3.50–4.49 Second Class Upper, 2.40–3.49 Second Class Lower, 1.50–2.39 Third Class and 1.00–1.49 Pass. A CGPA below 1.50 at the end of a year puts a student on probation for a session, so the lower bands matter as much as the top one.
Enter each course's units and grade to get the semester GPA, then add semesters with their total units for the CGPA and class. Some universities publish their own variations in handbooks; this calculator follows the NUC minimum standard.

How NUC calculates GPA and CGPA
Rules from the NUC Core Curriculum and Minimum Academic Standards (CCMAS) 2023, National Universities Commission (Nigeria):
- Courses are graded by percentage marks and letter grades on the 5-point scale above (Table 5).
- GPA = total units × grade points (TUGP) ÷ total number of units (TNU) for all courses taken in the semester; CGPA is calculated the same way over all courses taken during the period (Table 6).
- CGPA is expressed correct to two decimal places, and the class of degree is determined from it (Table 7); it must be at least 1.00.
- A CGPA below 1.50 at the end of a year places the student on probation for one session.
GPA = Σ(Ci × GPi) ÷ ΣCi
CGPA = Σ(GPAj × Cj) ÷ ΣCj
NUC grade points
| Grade | Grade point | Marks |
|---|---|---|
| A | 5 | 70–100 |
| B | 4 | 60–69 |
| C | 3 | 50–59 |
| D | 2 | 45–49 |
| E | 1 | 40–44 |
| F | 0 | 0–39 |
Classification by CGPA
| CGPA | Class / band |
|---|---|
| 4.5 and above | First Class Honours |
| 3.5 to below 4.5 | Second Class Honours (Upper Division) |
| 2.4 to below 3.5 | Second Class Honours (Lower Division) |
| 1.5 to below 2.4 | Third Class Honours |
| 1 to below 1.5 | Pass |
Worked example
The GPA example loaded above has 7 courses (3 credits at A, 3 credits at B, 2 credits at A and so on) worth 16 credits and 68 credit points, so the GPA is 68 ÷ 16 = 4.25.
For the CGPA, the example semesters (4.06 on 16 credits; 3.88 on 18 credits; 4.21 on 17 credits) give Σ(GPA × credits) = 206.37 over 51 credits, so the CGPA is 4.05.
