CGPA/SGPA Calculator
Calculate semester and cumulative grade point averages from credit-weighted grades.
About CGPA/SGPA Calculator
GPA is credit-weighted, so a high grade in a four-credit course moves the average more than the same grade in a one-credit course. The cumulative figure becomes progressively harder to shift as credits accumulate. After sixty credits a single strong semester moves the cumulative average by only a fraction of a point, which is why early grades matter disproportionately.
Formula
CGPA/SGPA
GPA = Σ(grade point × credits) ÷ Σ(credits)
- SGPA
- Semester grade point average, covering one term only
- CGPA
- Cumulative average across all terms, weighted by credits

Assumptions and limits
- The result is derived only from the 8 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is CGPA/SGPA calculated?
GPA = Σ(grade point × credits) ÷ Σ(credits) GPA is credit-weighted, so a high grade in a four-credit course moves the average more than the same grade in a one-credit course. The cumulative figure becomes progressively harder to shift as credits accumulate.
Why does CGPA/SGPA matter?
After sixty credits a single strong semester moves the cumulative average by only a fraction of a point, which is why early grades matter disproportionately.
