How is CGPA calculated in Nigeria?

CGPA is calculated with the standard weighted GPA formula: CGPA = Σ(Credit Units × Grade Points) ÷ Σ(Credit Units). Higher-credit courses carry more weight, so a 3-unit course affects your CGPA more than a 1-unit course with the same letter grade.

Is this calculator affiliated with any Nigerian university?

No. This is an independent calculator and is not affiliated with any university, polytechnic, or regulatory body. It is built around the standard Nigerian 5.0 grading method, but you should always compare your result with your institution's official handbook or transcript.

Can I calculate CGPA for multiple semesters?

Yes. You can add as many semesters as you need, and the calculator will show both the semester GPA and the running 5.0 CGPA automatically. This is useful for students tracking progress over several academic sessions.

Can I calculate my UNILAG CGPA here?

Yes. This calculator follows the standard Nigerian university 5.0 grading system used by UNILAG and most federal universities. If your department follows the usual 5.0 university scale, this page is a practical way to estimate your semester GPA and cumulative CGPA.

Can I use this as a UI or OAU CGPA calculator?

Yes. UI and OAU both fit the common Nigerian university 5.0 grading model that this page is built around. It works best as a planning tool for tracking results before you compare them with your official transcript or departmental handbook.

Does this work for UNN, ABU, UNILORIN, FUTA, or FUTO?

Yes. The calculator is intended for most Nigerian universities that use the standard 5.0 grading scale, including UNN, ABU, UNILORIN, FUTA, FUTO, UNIBEN, UNIPORT, and similar institutions using the usual A-to-F 5.0 structure.

Can I save my Nigerian CGPA result?

Yes. You can save the calculation locally in your browser and return to it later from History. You can also download the result as a PDF or PNG if you want a personal copy.

What CGPA is First Class in Nigeria?

At many Nigerian universities, a CGPA of 4.50 to 5.00 is treated as First Class. A CGPA of 3.50 to 4.49 is commonly Second Class Upper, while 2.40 to 3.49 is often Second Class Lower. The exact classification policy can vary slightly by institution, so always verify locally.

Do credit units matter in Nigerian CGPA calculation?

Yes. Credit units are central to the calculation. A course with 4 credit units contributes twice as much to your CGPA as a course with 2 units, so strong performance in heavier courses has a bigger impact.

Does this calculator save data to a server?

No. Your courses, grades, and credit units are stored only in your browser for local save and restore features. Nothing is transmitted to a server when you use the calculator.

How Nigerian CGPA Is Calculated

1The Formula

CGPA = Σ (Credit Units × Grade Points)

Σ Credit Units

Each course contributes quality points based on its grade point and credit unit value, and the total is divided by all units attempted.

2Nigerian Grade-Point Mapping

•A = 5.0 points (usually 70–100)
•B = 4.0 points (usually 60–69)
•C = 3.0 points, D = 2.0, E = 1.0, F = 0.0.
•Courses with higher credit units influence the cumulative result more heavily than lighter general courses.
