About CGPA Calculator

CGPA is the credit-weighted average of semester grade point averages, not the simple mean. A heavier semester therefore pulls the CGPA towards its GPA, which is why a strong result in a high-credit semester matters disproportionately.

Formula

CGPA

CGPA = Sum of (Semester GPA x Semester credits) / Total credits

Assumptions and limits

The result is derived only from the 4 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 3 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

Why is weighting by credits necessary?

Because a 24-credit semester represents more work than an 18-credit one. An unweighted mean treats them as equal and misstates the cumulative result.

Do failed courses count?

In most systems yes, at zero grade points but with their credits included, which is why a single failure has an outsized effect.
