CGPA calculator
What This Tool Does
CGPA (Cumulative Grade Point Average) combines your performance across multiple semesters into a single overall score, weighted by credit hours. This calculator adds up grade points and credits from each semester and returns your cumulative average.
You can also use this Hours Calculator.
How It's Calculated
CGPA = (Total Grade Points Earned Across All Semesters) ÷ (Total Credit Hours Attempted)
Each grade first converts to a grade point, typically on a 4.0 scale:
| Grade | Points |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
(Many institutions also use +/− grades like A− or B+, at 0.3 or 0.7 intervals — check your university's exact scale, since some cap at 4.0 and others go up to 4.3.)
Worked example: Semester 1: 15 credit hours, SGPA of 3.4. Semester 2: 18 credit hours, SGPA of 3.7.
- Semester 1 grade points: 15 × 3.4 = 51
- Semester 2 grade points: 18 × 3.7 = 66.6
- Total grade points: 51 + 66.6 = 117.6
- Total credit hours: 15 + 18 = 33
- CGPA: 117.6 ÷ 33 = 3.56
Edge Cases and Special Rules
- Scale differences: Not every institution uses the same maximum. Some cap CGPA at 4.0, others at 4.3, and some use a different scale entirely — always check which one applies before comparing your CGPA to a stated requirement.
- Percentage conversion: Converting CGPA to a percentage isn't standardized — different universities apply different formulas. Rather than guess, check your specific institution's official conversion table before using a CGPA-to-percentage figure for an application.
- Excluded grades: Pass/fail, incomplete, and withdrawal grades are usually excluded from the CGPA calculation entirely, since they don't carry a standard grade point.
- Rounding: CGPA is typically rounded to two decimal places, which is why small differences in individual course grades can matter for borderline cases.
CGPA Conventions Vary by University
Pakistani universities each set their own grading policy, and the exact formula or scale can differ from one institution to the next — UAF, NUST, IUB, UOL, UCP, COMSATS, UET, Punjab University, Virtual University, and University of Gujrat all publish their own grading guides. If you need an exact percentage equivalent or official CGPA threshold for a scholarship, degree requirement, or transfer, check your university's own conversion table rather than relying on a general formula.
Who Uses This
- University students tracking cumulative performance across multiple semesters
- Students applying for scholarships or graduate programs that specify a minimum CGPA
- Students converting CGPA to a percentage for job or university applications
- Anyone planning ahead to see what CGPA future semesters need to reach a target
CGPA vs. SGPA
These are often confused. SGPA (Semester Grade Point Average) covers a single semester only. CGPA is cumulative — it combines every semester completed so far, weighted by each semester's credit hours. Your SGPA can go up or down semester to semester, but your CGPA moves more gradually since it reflects your entire academic record.
FAQ
What is CGPA?
Cumulative Grade Point Average — your overall grade point average across all completed semesters, weighted by credit hours.
How is CGPA different from GPA?
GPA often refers to a single semester's average, while CGPA is cumulative across every semester completed.
How do I convert CGPA to a percentage?
The formula varies by institution — check your university's official conversion table rather than a general one.
Is CGPA calculated out of 4 or 4.3?
It depends on your institution's grading policy — both scales are common, so confirm which one your university uses.
Does this work for Pakistani university grading systems?
Yes, as long as you enter grade points and credit hours matching your university's own scale.
