How to Calculate GPA and CGPA

CGPA stands for Cumulative Grade Point Average, while GPA stands for Grade Point Average. GPA usually measures performance for one semester or study period, while CGPA combines results across multiple semesters. A credit-weighted calculation gives subjects with more credits a proportionally larger effect on the result.

Enter every subject's credit value and grade point exactly as they appear in your institution's grading system. The calculator multiplies credits by grade points, totals the resulting quality points, and divides by the total credits.

If your transcript shows letter grades, use the 10-point letter-grade mode to select A+, A, B, C, or D. The included mapping assigns 10, 9, 8, 7, and 6 points respectively. Credits determine how much each subject contributes; they do not change the letter grade's point value.

GPA and CGPA Formulas

Semester GPA

GPA = Sum of (subject credits × grade point) ÷ total semester credits.

Cumulative CGPA

CGPA = Total quality points from all semesters ÷ total credits from all semesters.

Example

A four-credit subject with grade point 9 contributes 36 quality points. A three-credit subject with grade point 8 contributes 24. Together, the GPA is (36 + 24) ÷ (4 + 3) = 8.57.

Before Entering Your Grades

  • Confirm whether your institution uses a 4, 5, 10, or custom point scale.
  • Use registered or earned credits according to your official academic policy.
  • Check how repeated, failed, withdrawn, audit, and pass/fail subjects are treated.
  • Use the percentage conversion formula published by your institution.

Plan for a Target CGPA

The target planner uses your current credits and quality points to estimate the average GPA required across future credits. Try realistic targets and credit loads to understand how upcoming semesters could influence your cumulative result.

This is a planning estimate, not an academic guarantee. Course availability, credit structures, grade replacement policies, and rounding rules can change the official result.

CGPA-to-Percentage Conversion Is Institution-Specific

A 10-point CGPA does not automatically equal CGPA × 10 or CGPA × 9.5. Different universities and boards publish different formulas, and some do not provide a direct conversion. Use your official academic regulations whenever the percentage is needed for admissions, employment, scholarships, or formal documents.
