🎓 GPA / CGPA Calculator

Calculate credit-weighted grades using the scale your institution uses.

Course entry mode Quick GPA: enter grade points Custom grading system: define and select letter grades

Courses and grade points

Enter the grade-point value assigned by your institution for each course. Zero is allowed; Quick GPA has no fixed maximum, so use your institution's scale.

Calculate cumulative GPA (CGPA)

Choose one method. CGPA is weighted by credits; do not average semester GPAs without weighting.

Previously completed credit hours

First calculate this semester's GPA above. The semester's course credits are added to your previous completed credits.

Enter each semester's GPA and earned credit hours according to your institution's rules.

How GPA and CGPA Are Calculated

A grade point average summarizes course results while accounting for the credit hours assigned to each course. This GPA and CGPA Calculator lets you enter grade points directly or define the letter-grade values used by your institution.

What Is a Semester GPA?

A semester GPA is the weighted average of the grade points earned in courses during a term. A course with more credits contributes more to the result than a course with fewer credits.

The Credit-Weighted GPA Formula

For each course, multiply its grade points by its credit hours. Add those products, then divide by the sum of the included credit hours.

Semester GPA = Σ (course grade points × course credits) ÷ Σ course credits

For example, a 4-credit course with 3.7 points and a 2-credit course with 3.0 points produce (4 × 3.7 + 2 × 3.0) ÷ (4 + 2) = 3.467 before display rounding.

Use Your Institution's Grading Scale

Institutions can use different letter grades, grade-point values, credit rules, and rounding policies. In Custom Grading System mode, enter the letter grades and point values from your institution, then select a grade for each course. The listed points are inputs to the calculation and are not a universal standard.

Quick GPA mode accepts grade points directly when you already know the point value for each course.

How CGPA Combines Coursework

CGPA is calculated by weighting grade averages by credits. When you enter a previous CGPA and completed credits, the calculator combines those quality points with the current semester's weighted GPA and credits.

Combined CGPA = (previous CGPA × previous credits + current semester GPA × current semester credits) ÷ total credits

You can also enter GPA and credits for multiple semesters. The calculator combines their weighted points rather than taking a simple average of semester GPAs.

Check Credit and Institutional Rules

Enter the credits your institution counts toward the GPA. Some institutions exclude particular courses, use repeated-course replacement rules, or apply special treatment to pass/fail courses. Follow your transcript or academic handbook when deciding which grades and credits to include.

GPA Is Not Automatically a Percentage

There is no single percentage conversion that applies to every institution or grading scale. This calculator reports weighted GPA values only. Use a percentage conversion only when your institution publishes the specific formula that applies to your records.

Rounding and Results

Results display to three decimal places. The displayed value is rounded for presentation; institutions may retain more precision or apply their own rounding rules, so an official transcript can differ slightly.
