CGPA calculator: cumulative GPA from your semesters
Free TutorAura tool · no sign-up · Updated
Enter the GPA (or SGPA) and credit hours for each semester, and the calculator gives your cumulative GPA (CGPA), weighted by credit hours as universities calculate it. Switch to GPA from courses to work out one semester from each course's grade point and credits. It works on any scale (4.0, 5.0 or 10). To convert to a percentage, enter the formula your university uses.
How CGPA is calculated
CGPA is a credit-weighted average: each semester's GPA counts in proportion to its credit hours.
Example: semester 1, GPA 3.4 over 18 credit hours; semester 2, GPA 3.7 over 17 credit hours.
A plain average of 3.4 and 3.7 would be 3.55 here too, but only because the credit hours are nearly equal. With very different credit loads, the plain average is wrong.
Semester GPA (SGPA) from courses
Within one semester, each course's grade becomes a grade point (for example, A = 4.0 on a 4-point scale). Multiply each grade point by the course's credit hours, add them up, and divide by the total credit hours. A 3-credit course counts more than a 1-credit lab. Your university's grading policy lists which letter grade or marks range gives which grade point.
Converting CGPA to a percentage
There's no single conversion. Each university or board sets its own, and some print the formula on the transcript. Common forms are a multiplier (CGPA × some number), a multiplier after subtracting a constant, or a straight proportion (CGPA ÷ scale × 100). Enter your institution's formula in the converter and it does the arithmetic. If a university you're applying to asks for a percentage, use the conversion it asks for, or send the official one from your own university.
To convert a CGPA you already have, to a GPA out of 4, a percentage (including CBSE's × 9.5) or marks out of 500 or 600, use the CGPA to GPA converter.
Raising your CGPA
Because CGPA is weighted by credit hours, high-credit courses move it most. The further you are into your degree, the more credits are already counted, so each new semester changes your CGPA a little less. You can see this by adding a semester with your target GPA: the result shows what a strong semester would do. Steady study beats last-minute cramming; see the best study techniques.
GPA, SGPA and CGPA
- GPA: a grade point average, for a course load or period.
- SGPA: semester grade point average, for one semester.
- CGPA: cumulative grade point average, across all semesters so far.
Schools in the US usually use a 4.0 scale; many universities in South Asia use 4.0 or 10-point scales. For a US high school GPA with honours and AP weighting, use our GPA calculator.
Frequently asked questions
Is CGPA the average of my semester GPAs?
Only if every semester has the same credit hours. Otherwise, weight each semester by its credit hours, which is what this calculator does.
How do I convert CGPA to a percentage?
Use the formula your university sets, often printed on the transcript or in the academic regulations. Enter it in the converter below the result.
How do I convert my CGPA to a GPA out of 4?
Divide by your scale and multiply by 4: a 7.5 out of 10 is 3.0 out of 4. Our CGPA to GPA converter does this, plus percentages and marks out of any total.
Does it work on a 10-point scale?
Yes. The CGPA calculation is the same on any scale. Set the scale in the converter so the straight-proportion percentage is right.
What are credit hours?
How much a course counts, roughly the hours of teaching per week. Your timetable or course list shows each course's credits.
Is anything I type sent to a server?
No. Everything runs in your browser, and nothing you type is sent to TutorAura.
