CGPA Calculator

Your CGPA is the credit-weighted average of your semester GPAs: CGPA = Σ (semester GPA × credits) ÷ Σ credits. Add each semester's GPA and credits to see your cumulative figure, an approximate percentage (CGPA × 9.5; check your institution's table) and the GPA your next semester needs to reach a target.

How to use the CGPA Calculator

  1. 1Add a row for each semester you have completed.
  2. 2Enter that semester's GPA and the number of credits it carried.
  3. 3The cumulative CGPA updates as you add rows.
  4. 4Use the projection box to see what a future semester would do to your CGPA.

How it works

A CGPA is a weighted average of semester GPAs, using each semester's credit load as its weight. Semesters where you took more credits therefore pull the cumulative figure harder — which is why a light semester with a perfect GPA moves the total less than students often expect.

The projection tool answers the practical question directly: given where you are now, what GPA does the next semester need for you to reach a target? It rearranges the same weighted-average formula to solve for the unknown term, and tells you plainly when the target is not reachable in one semester.

The percentage conversion, shown when the scale is 10, uses the widely published CGPA × 9.5 formula. It is an approximation adopted by several boards, not a universal standard — your institution's own conversion table always takes precedence.

The formula

CGPA = Σ (semester GPA × semester credits) ÷ Σ semester credits
semester GPA
the grade point average for that term
semester credits
total credit hours attempted that term
Σ
the sum across every semester entered

Tips and common mistakes

  • Enter each semester's credits as well as its GPA. A heavy semester counts for more than a light one.
  • Use the projection to see what next semester needs before planning your course load.
  • Treat the × 9.5 percentage conversion as an estimate and use your institution's own table for anything official.
  • Remember that early semesters set the baseline; the more credits you complete, the less any single term can move the total.

Frequently asked questions

How do I convert CGPA to a percentage?
The common approximation is CGPA × 9.5, so a CGPA of 8.2 is about 77.9%. Check your institution's official table, because conversions vary.
Why did my CGPA barely move after a great semester?
Because it is weighted by credits and averaged over everything you have done. The more credits already behind you, the less any single term can shift the total.
Can I see what I need next semester to hit a target?
Yes. Enter your target CGPA and the credits you plan to take, and the tool works out the GPA that semester would need — or tells you if it is out of reach.
Is CGPA just the average of my semester GPAs?
No. Each semester is weighted by its credits. Semesters of 3.48 over 13 credits and 3.80 over 17 give a CGPA of 3.66, not the simple average of 3.64.
Does it work on a 10-point scale?
Yes. The calculation is the same on any scale, as long as every semester you enter uses the same one.
Should I enter credits attempted or credits earned?
Credits attempted, which is what most institutions use for the average. If your institution counts differently, follow its rules.
