How to use this GPA calculator

  1. Select your grading scale (4.0 for US/international, 10.0 for most Indian universities).
  2. Enter each course name, credit hours, and grade.
  3. Add more courses with the “Add course” button.
  4. Your semester GPA updates instantly.
  5. Optionally enter your previous CGPA and total credits earned to see your updated cumulative GPA.

Why credit hours matter

Not all courses are equal weight. A 4-credit core course has twice the impact on your GPA as a 2-credit elective. Getting a B in a 4-credit course hurts more than getting a B in a 2-credit course. Focus study time proportionally — prioritise high-credit courses for GPA impact.

Converting CGPA to percentage

Many employers and graduate programmes ask for percentage equivalents. Common conversions: Multiply CGPA by 9.5 (CBSE standard); multiply by 10 and subtract 7.5 (VTU method); or use your university's official conversion formula stated on your transcript.

Frequently asked questions

How is GPA calculated?
GPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours). Each course grade is converted to grade points (A = 4.0, B = 3.0, etc.), multiplied by the credit hours for that course, summed together, then divided by total credit hours. This is a weighted average that accounts for the relative weight of each course.
What is the difference between GPA and CGPA?
GPA (Grade Point Average) typically refers to a single semester. CGPA (Cumulative GPA) is the overall average across all semesters. This calculator computes both — enter your previous CGPA and total credits to see how this semester's results affect your cumulative standing.
What is the 10-point scale used in Indian universities?
Most Indian universities (IITs, NITs, BITS, and many state universities) use a 10-point CGPA scale. Grades are typically: O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4, F = 0. To convert to a 4.0 scale: CGPA × 0.4 (approximate). Note: IITs may use slightly different grade boundaries.
What is a good GPA?
On a 4.0 scale: 3.7–4.0 = summa cum laude / distinction; 3.5–3.69 = magna cum laude; 3.0–3.49 = cum laude; 2.5–2.99 = satisfactory; below 2.0 = academic probation at many institutions. On a 10.0 scale: 9–10 = excellent; 7.5–9 = very good; 6–7.5 = good; below 5 = at risk.
How many credits is a typical course?
In India, most undergraduate courses are 3–4 credits. Lab courses are typically 1–2 credits. Final year projects can be 4–6 credits. A full semester is usually 20–25 credits. In the US system, a 3-credit course meets for 3 hours per week.
