SGPA calculator

Formula SGPA = Σ (grade point × credits) ÷ Σ credits 115.0 ÷ 14 = 8.21

Credits are weighted. Averaging grade points without credits is the most common error in competing tools.

Credits are the whole point

SGPA is a credit-weighted average, not a plain average of grade points. A four-credit core subject moves your SGPA twice as much as a two-credit elective, so the arithmetic mean of your grades is almost never your SGPA. This is the single most common defect in competing calculators.

Multiply each grade point by that subject’s credits, add the products, then divide by total credits. Non-uniform credits are the normal case in an Indian engineering semester, where theory, labs and mandatory courses carry different weights.

Zero-credit audit courses appear on the transcript but do not enter the calculation. Backlog subjects usually enter in the semester they are cleared, at the grade obtained, which is why a cleared backlog can pull an otherwise strong semester down.

CGPA is then the same operation one level up: the credit-weighted average of every semester completed so far, not the average of your SGPAs. Once you have the number, SGPA to percentage converts a single semester and CGPA to percentage converts the cumulative figure.

Three mistakes to avoid

01
Averaging grade points without credits This is the default error. It overstates your SGPA whenever your weaker subjects carry more credits.
02
Including zero-credit audit courses They belong on the transcript, not in the average.
03
Averaging SGPAs to get CGPA CGPA weights each semester by its credits too. Semesters are rarely equal.

Frequently asked

Is SGPA the average of my grade points?
No. It is the average weighted by each subject’s credits.
Do failed subjects count?
Yes, at zero points, until they are cleared. That is why one F is disproportionately expensive.
How do I get CGPA from SGPA?
Take the credit-weighted average of all semesters, using each semester’s total credits as the weight.
What if my university uses letter grades I do not see here?
Use the grade point printed in your grade card. The letters differ between universities; the points are what matter.
Can I add more than five subjects?
Yes, up to fifteen rows. Use "Add subject".
