SGPA to CGPA calculator

A CGPA is a credit-weighted average of semester SGPAs. Each semester contributes its SGPA multiplied by the credits it carried, and the total is divided by the total credits:

The reverse question rearranges the same equation. If you know your CGPA so far, the credits behind it, the credits still to come and the CGPA you want to end on, the average the rest of the degree has to hit is:

If that number comes out above the top of your scale, the target is not reachable, and the page says so and gives you the best CGPA still available instead of printing an impossible figure.

Averaging the SGPAs directly is only correct when every semester carries exactly the same number of credits. As soon as they differ, the two answers separate, and the credit-weighted one is what appears on a transcript.

Take two semesters: a 9.0 across 10 credits, and a 7.0 across 30 credits. The plain average of 9 and 7 is 8.0. The credit-weighted figure is 90 grade points plus 210, divided by 40 credits, which is 7.5. Half a grade point of difference, purely because the weaker semester carried three times the load.

This is also why a strong short semester rescues less than it feels like it should, and why a target CGPA gets harder to move the further into a degree you are: the credits already banked outweigh the ones left.

Say you hold a CGPA of 7.0 across 80 credits, with 20 credits left, and you want to finish on 7.5. A 7.5 across 100 credits is 750 grade points. You already hold 7.0 times 80, which is 560. The shortfall of 190 has to come out of 20 credits, so you need an average of 9.5.

Change the target to 8.0 and the sum becomes 800 minus 560, which is 240 over 20 credits, an average of 12. That is above a 10-point scale, so the answer is that it cannot be done. The best available is 10 across the remaining 20 credits, which lands you at 7.6.

How do I convert SGPA to CGPA?

Multiply each semester's SGPA by the credits that semester carried, add those products together, and divide by the total credits. That credit weighting is what turns several semester figures into one cumulative figure.

Can I just average my SGPAs?

Only if every semester carried exactly the same number of credits. When credits differ, a plain average and a credit-weighted CGPA give different answers, and the credit-weighted one is what a transcript shows. The calculator prints both so you can see the gap.

What SGPA do I need next semester to reach my target CGPA?

The reverse mode answers that. It takes your current CGPA, the credits behind it, the credits still to come and your target, then solves for the average the remaining credits have to hit. If that number is above the top of your scale it says the target is out of reach and shows the best CGPA still available.

Do all universities calculate CGPA the same way?

No. Credit weighting is the common core, but institutions differ on whether failed or repeated papers count, whether audit courses carry credits, how a supplementary attempt is treated and whether the figure is rounded or truncated. Check your own academic regulations, because your university's rule is the one that appears on your transcript.

Does this work on a 4-point scale?

Yes. Set the scale to 4 and enter your semester GPAs on that scale. The arithmetic is identical, only the ceiling changes, and the validation follows the scale you picked.

How do I turn my CGPA into a percentage?

That is a separate conversion with its own institution-specific rule, so it lives on the CGPA to percentage converter rather than here. That page names the formula it applies rather than picking one silently.
