How to Use This Tool

For each subject, note its credit value and the grade point you earned (usually on a 10-point scale).
Enter them one per line in the format credit,gradepoint — for example, "4,9" for a 4-credit subject where you scored a grade point of 9.
Click Calculate CGPA to get your credit-weighted result.

The Credit-Weighted Average Formula

CGPA is calculated as a credit-weighted average of your grade points — subjects with more credits count proportionally more toward your final result than lower-credit subjects:

CGPA = Σ(Credit × Grade Point) ÷ Σ(Credit)

This calculator sums the product of each subject's credit and grade point, then divides by the total credits, giving you the correct weighted result rather than a simple unweighted average.

KTU Grading Scale

KTU (APJ Abdul Kalam Technological University) uses a 10-point grading scale (S=10, A+=9, A=8.5, B+=8, B=7, C+=6.5, C=6, D=5.5, P=5, F=0). Use your KTU grade card's grade points directly in this calculator.

Why Credit Weighting Matters

Without credit weighting, a 1-credit elective and a 4-credit core subject would count equally toward your average — which doesn't reflect their actual academic weight. Credit-weighting ensures your result accurately reflects the relative importance for each subject in your curriculum.

Common Mistakes to Avoid

Forgetting to include a subject with a very low or failing grade point, which can significantly skew your actual average
Using semester-level credits when the calculation should use subject-level credits, or vice versa
Mixing up grade point scales (e.g., entering a percentage instead of the 10-point grade point value)

Frequently Asked Questions

What is the formula for CGPA?

CGPA is calculated as the sum of (credit × grade point) for each subject, divided by the total credits — a credit-weighted average rather than a simple average.

What if I don't know my exact grade point for a subject?

Check your official grade card or your university's grading scale, which maps letter grades (like O, A+, A, B+) to numeric grade points, usually on a 10-point scale.

Can I use this calculator for any university?

Yes, since it applies the universal credit-weighted average formula. Just make sure you're using grade points consistent with your specific university's grading scale.
