SGPA to CGPA Calculator and Conversion Formula

Filling in the SGPA to CGPA calculator

Each row is one semester. In the first box type the SGPA from that semester's grade card, such as 8.12. In the second box type that semester's total credits, such as 24. The credits box says optional because without it the semesters are weighted alike and you get a plain average. In short, this SGPA to CGPA converter doubles as a CGPA calculator from SGPA values printed on your cards.

Six rows are ready, enough for three years. Press + Add row for semesters 7 and 8. The result panel gives the CGPA, the plain average next to it so you can see the gap, and the same CGPA under common percentage rules. The working line prints every SGPA x credits product, which makes it easy to spot a typing error.

1. Write down each semester's SGPA and total credits.
2. Multiply each SGPA by its credits.
3. Add all the products.
4. Add all the credits.
5. Divide the first total by the second.

SGPA to CGPA formula explained

SGPA (Semester Grade Point Average) covers one semester. CGPA (Cumulative Grade Point Average) covers everything so far. You cannot get the CGPA by adding SGPAs or by averaging them blindly, because a semester with more credits holds more grade points.

The right way is to go back to credit points. A semester's credit points are its SGPA times its credits. Add the credit points of all semesters and divide by all the credits. This is exactly how universities do it: SRM's regulations, for instance, define CGPA as semester credits times SGPA, totalled, over total credits.

Some universities compute CGPA straight from every course rather than from SGPAs. The answer is the same as long as you use each semester's full registered credits and the SGPA to two decimals.

Two semesters: CGPA from SGPA step by step

Students often ask how to calculate the CGPA from SGPA once there are many semesters, and how to find the CGPA from SGPA values quickly. Keep adding rows. The table below follows one student through six semesters so you can see the running CGPA move.

CGPA to SGPA: working backward

Two backward questions come up often. Both use the same credit points idea, so the steps below work as a simple CGPA to SGPA converter by hand.

Because the printed CGPA is rounded, a backward figure can be off by a hundredth or two. Trust the grade card over the calculation.

SGPA to CGPA of one semester

After the first semester there is nothing to average, so your CGPA equals your SGPA. Many universities, VTU among them, print a CGPA only from the second semester for this reason. If a form asks for CGPA while you have finished only one semester, write the SGPA and mention that it is for semester 1.

To convert the result into a percentage, use your university's rule on the final CGPA. For one semester see SGPA to percentage; for the final figure, every university rule is collected under CGPA to percentage.

Errors that give a wrong CGPA

Whether a failed course stays in at zero differs by university. VIT and SRM count it, Anna University leaves it out until you pass. Each university page on this site follows its own rule; VTU students can check theirs on the VTU CGPA calculator.

Where to find SGPA and credits

Each semester grade card prints a summary line with credits registered, credits earned, SGPA and, from semester 2, CGPA. If the card lists only course credits, add the credits of every course you registered for in that semester. The overall CGPA calculator covers final year totals, lateral entry and the CGPA printed on the degree grade sheet.
