CGPA Calculator

Calculate your Cumulative Grade Point Average (CGPA), track academic progress, and estimate graduation performance.

CGPA Calculator

Calculate your cumulative grade point average across all completed semesters. The calculator combines each semester's GPA (or SGPA) with its credit load to produce one credit-weighted figure for your whole academic record so far.

CGPA formula

Cumulative GPA is not a plain average of semester GPAs. Each semester counts in proportion to its credits:

CGPA = sum(semester GPA x semester credits) / sum(semester credits)

Equivalently, you can compute it from individual courses: total grade points earned across every course, divided by total credits attempted. Both routes give the same number.

Scales vary worldwide. Many universities in India and elsewhere use a 10-point scale, where each course earns a grade point from 0 to 10 and the cumulative result is often called CGPA, while US institutions typically report a cumulative GPA on a 4.0 scale. Some schools also publish a conversion between CGPA and percentage, such as percentage = CGPA x 9.5 — but that multiplier is a convention of specific boards, not a universal rule, so use only your institution's official conversion.

Worked example

A student on a 10-point scale has completed three semesters:

  • Semester one: 22 credits at SGPA 8.2 gives 8.2 x 22 = 180.4 weighted points.
  • Semester two: 24 credits at SGPA 7.5 gives 7.5 x 24 = 180.0 weighted points.
  • Semester three: 22 credits at SGPA 8.0 gives 8.0 x 22 = 176.0 weighted points.

Total weighted points are 180.4 + 180.0 + 176.0 = 536.4 over 22 + 24 + 22 = 68 credits. The CGPA is 536.4 / 68 = 7.89 (rounded to two decimal places). A simple average of the three SGPAs would give (8.2 + 7.5 + 8.0) / 3 = 7.9 — close here because the credit loads are similar, but the two methods diverge when semesters carry different credit counts, and only the credit-weighted version matches your transcript.

When to use this calculator

  • Tracking whether your cumulative average stays above a placement or internship cutoff, such as a 7.5 CGPA requirement.
  • Estimating how strongly a good or bad upcoming semester can move a total that already includes many credits.
  • Preparing applications for exchange programs or graduate study that ask for a cumulative figure.
  • Reconciling your own records with the CGPA printed on a grade card before raising a query with the registrar.

Tips for accurate results

  • Confirm whether your institution weights by credits or averages SGPAs directly; most weight by credits.
  • Include every graded semester, including any with backlogs or repeated courses, according to your university's repeat policy.
  • The more credits you accumulate, the less a single semester can shift your CGPA — plan improvements early.
  • Use your institution's official CGPA-to-percentage conversion for applications; ad hoc multipliers may be rejected.
  • Keep the same rounding convention as your grade card, typically two decimal places.

Frequently asked questions

How is CGPA different from GPA?
GPA (or SGPA) usually refers to one semester's average, while CGPA is the cumulative average over every completed semester. CGPA weights each semester by its credit load, so a 24-credit semester influences the total more than an 18-credit one. Both are computed as total grade points divided by total credits.
Is CGPA a simple average of my semester GPAs?
Only when every semester carries exactly the same number of credits. Otherwise, you must multiply each semester GPA by its credits, sum those products, and divide by total credits. The credit-weighted result is what appears on transcripts, and it can differ noticeably from a plain average when credit loads vary.
How do I convert CGPA to a percentage?
There is no universal conversion. Some boards use percentage = CGPA x 9.5 on a 10-point scale, but other universities publish their own formulas or conversion tables. For job and admission applications, use only the conversion your institution officially specifies, since ad hoc formulas may be rejected.
What is a 10-point CGPA scale?
On a 10-point scale, common at universities in India and several other countries, each course earns a grade point from 0 to 10 (for example, O or A+ grades near 10 and passing grades near 4 or 5). The cumulative average of these points, weighted by credits, is the CGPA. Grade letters and cutoffs vary by university, so check your own grade card.
Why does my CGPA change so little each semester?
Because CGPA is weighted by all credits earned so far, each new semester is a progressively smaller fraction of the total. After six semesters, even an outstanding term shifts the cumulative figure by only a few tenths of a point. This is why improving early in a program has the largest effect.
