What Is the Nigeria 5.0 CGPA Calculator?
Essential definitions, letter-to-point mappings, and systemic academic context.
Nigerian universities accredited by the NUC evaluate academic performance on a 5.00 cumulative grade point average (CGPA) scale. Marks of 70% and above earn an A grade (5 points), 60โ69% earn a B (4 points), 50โ59% earn a C (3 points), 45โ49% earn a D (2 points), 40โ44% earn an E (1 point), and below 40% is an F (0 points).
Total Credit Units (TCU) multiplied by Grade Points earned produces Total Weighted Grade Points (TWGP / Total Quality Points).
Degree Classification Benchmarks: First Class Honours (4.50 โ 5.00), Second Class Upper Division (3.50 โ 4.49), Second Class Lower Division (2.40 โ 3.49), Third Class (1.50 โ 2.39).

How the Nigeria 5.0 CGPA Calculator Works (Step-by-Step Calculation Flow)
The complete mathematical path from qualitative classroom marks to cumulative transcript GPA.
Map Course Score to NUC Grade Points
70-100% = A (5), 60-69% = B (4), 50-59% = C (3), 45-49% = D (2), 40-44% = E (1), 0-39% = F (0).
Multiply by Course Credit Units
Multiply course grade points by credit units (e.g., 2, 3, or 4 units).
Sum Weighted Points & Total Units
Sum all quality points and separately sum all registered credit units for the semester.
Compute Semester GPA & Cumulative CGPA
Divide Total Weighted Grade Points by Total Credit Units: CGPA = ฮฃ(TWGP) รท ฮฃ(TNU).

Worked Calculation Example (Manual Verification)
A typical engineering semester at a federal university in Nigeria.
| Course Title | Letter Grade | Grade Points | Credit Hours | Quality Points |
|---|---|---|---|---|
| Engineering Mathematics II | A | 5.00 | 3 | 15.00 |
| Thermodynamics | B | 4.00 | 3 | 12.00 |
| Strength of Materials | A | 5.00 | 3 | 15.00 |
| Fluid Mechanics I | A | 5.00 | 3 | 15.00 |
| Computer Programming | B | 4.00 | 3 | 12.00 |
| Engineering Workshop Practice | A | 5.00 | 3 | 15.00 |
| Total Summary | 18 Credits | 84.00 Total Quality Points | ||
Step-by-Step Arithmetic:
- Step 1: Convert grades: Eng Maths (A=5), Thermo (B=4), Strength (A=5), Fluids (A=5), Prog (B=4), Workshop (A=5).
- Step 2: Multiply by 3 credit units each: (3ร5=15), (3ร4=12), (3ร5=15), (3ร5=15), (3ร4=12), (3ร5=15).
- Step 3: Total Weighted Grade Points = 84.00 | Total Credit Units = 18.0.
- Step 4: Divide: 84.00 รท 18.0 = 4.666... โ Round to 4.67 CGPA.

Nigerian 5.0 Standard
All Nigerian universities evaluate degrees strictly on the 5-point scale.
Degree Class Boundaries
A 4.50+ CGPA is strictly required for First Class; 3.50โ4.49 yields Second Class Upper.
Credit Unit Weighting Impact in Nigeria
4-unit departmental core courses exert double the influence of 2-unit general studies (GST) courses on cumulative CGPA.
Weighted CGPA is 26.0 รท 6 = 4.33 (Second Class Upper) vs 4.00 simple average.

Nigerian University Academic Regulations
Key NUC regulatory guidelines governing CGPA calculation:
Carryover & Course Retake Rules
When a student fails a course (F), both the 0 grade points and credit units remain in the transcript, and the retake attempt is factored additionally into cumulative TNU.
Advice to Withdraw (ATW)
Students whose cumulative CGPA remains below 1.50 at the end of two consecutive semesters are placed on probation or advised to withdraw.
Important Calculation Limitations & Edge Cases
Special academic situations that may alter how your official university transcript GPA is computed.
70% First Class Benchmark
In Nigeria, 70% represents an A grade and First Class Honours, which is significantly higher in academic standing than a 70% in North America (where 70% is a C).
