GPA / CGPA Calculator

Calculate grade point averages

How the GPA & CGPA Calculator Works

Our GPA calculator helps students compute their Grade Point Average quickly and accurately. Whether you are tracking a single semester or calculating your cumulative GPA across your entire academic career, this tool handles both 4.0 and 10.0 grading scales with support for letter grades and direct grade-point entry.

Simply add your courses, enter the credit hours and corresponding grades, and the calculator instantly computes your semester GPA. To find your CGPA, include courses from all semesters. The tool also provides a breakdown showing each course's quality points so you can see exactly how every class affects your average.

GPA Formula

GPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours)

Each letter grade maps to a numeric value on the 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0. Multiply each grade value by the number of credit hours for that course to get quality points. Sum all quality points across courses and divide by total credit hours to arrive at your GPA. For a 10.0 scale, the same weighted-average principle applies with the grade values adjusted accordingly.

Understanding this formula empowers you to plan ahead — you can estimate how different grades in future courses will impact your overall CGPA and set realistic academic targets.

Frequently Asked Questions

To calculate GPA, multiply each course's grade points by its credit hours to get quality points. Then sum all quality points and divide by the total credit hours. The formula is: GPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours). For example, if you earned an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course, your GPA = (4.0×3 + 3.0×4) / (3+4) = 24/7 = 3.43.

On a 4.0 scale, a GPA of 3.5 or above is generally considered excellent, 3.0–3.4 is good, 2.5–2.9 is average, and below 2.0 may put you on academic probation. For graduate school admissions, a GPA of 3.0 or higher is typically required, while competitive programs often look for 3.5+. What counts as "good" also depends on your field, institution, and career goals.

GPA (Grade Point Average) typically refers to a single semester or term average, while CGPA (Cumulative Grade Point Average) represents your overall average across all semesters combined. GPA measures performance in a specific period, whereas CGPA provides a comprehensive view of your entire academic career. Both use the same calculation method but differ in scope.

The conversion from GPA to percentage varies by institution and scale. A common method for a 4.0 scale is: Percentage = (GPA / 4.0) × 100. Another widely used formula is: Percentage = (GPA × 25) or (CGPA × 9.5) for a 10-point scale used in some countries. For example, a 3.5 GPA on a 4.0 scale is approximately 87.5%. Always check your institution's specific conversion chart for accuracy.
