CGPA Calculator

Quick answer

CGPA (Cumulative Grade Point Average) is the weighted average of your semester GPAs across all completed semesters. The CBSE 10-point system uses CGPA × 9.5 to get the equivalent percentage — a formula that comes directly from the CBSE Class 10 grading rule.

What is CGPA Calculator?

CGPA is a single number that summarises your academic performance across multiple semesters. It is used by Indian universities, IITs, NITs, and CBSE schools to report cumulative results. Different institutions use different scales — CBSE uses 10, most engineering colleges use 10, some universities use 4 or 5.

The 'cumulative' part is what distinguishes CGPA from a single semester's GPA. CGPA averages all semester GPAs together, weighted by credits if applicable. If a semester has more credit hours, it weighs more. Equal-weight averaging works when each semester has the same credits.

The CBSE Class 10 board converts CGPA to percentage by multiplying by 9.5. So a CGPA of 8.0 = 76% under their formula. This conversion is specific to CBSE — engineering universities use their own conversion (often percentage = (CGPA − 0.5) × 10) or do not convert at all.

Computing CGPA

Formula

Equal-weight: CGPA = Σ semester GPAs ÷ number of semesters Weighted (credits): CGPA = Σ (GPAᵢ × creditsᵢ) ÷ Σ credits Approximate %: CBSE: % = CGPA × 9.5

GPAᵢ: Semester GPA—Grade Point Average for semester i
creditsᵢ: Semester credits—credit hours assigned to that semester

Worked example

Semester GPAs8.5, 9.0, 8.7, 9.2, 8.9

Sum = 44.3

Count = 5

CGPA = 44.3 / 5 = 8.86

% (CBSE) = 8.86 × 9.5 = 84.17%

➜ CGPA: 8.86 • Approx %: 84.17%

How to use this calculator

Enter your semester GPAs as comma-separated values. Optionally add credit hours for weighted average.

Enter semester GPAs
List of numbers like '8.5, 9.0, 8.7'. Each value should be on the same scale (usually out of 10).
Enter credit hours (optional)
If your semesters have different credit weights, list them in the same order. Leave blank for equal-weighted average.
Read CGPA and percentage
The calculator returns the CGPA value and the CBSE-equivalent percentage.

When to use CGPA

College admissions

Most masters programs require CGPA reporting. The single number is what the admissions committee compares first.

Job placements

Campus placements often have CGPA cutoffs (e.g., 7.0+). Make sure your CGPA crosses the threshold for your dream company.

Scholarship eligibility

Many scholarships require minimum CGPA. Track yours after each semester to stay eligible.

Higher studies abroad

Foreign universities sometimes ask for percentage rather than CGPA. The CBSE × 9.5 conversion gives a starting estimate; some schools use their own equivalence.

Common mistakes to avoid

Mixing 10-point and 4-point GPAs

Convert all to one scale before averaging. A 4-point GPA of 3.5 ≈ a 10-point GPA of 8.75.

Using percentage = CGPA × 9.5 for engineering CGPA

The 9.5 multiplier is CBSE Class 10 specific. Engineering universities have their own conversions — check your institute's rule.

Glossary

CGPA: Cumulative Grade Point Average — weighted average across all completed semesters.
GPA: Grade Point Average for a single semester.
Credit hours: Numerical weight assigned to a course based on study hours. Used for weighted CGPA.
Grade points: Numeric value assigned to each letter grade (e.g., A=10, B=8). Calculated per course, summed per semester.
Percentage equivalent: Approximate percentage corresponding to a CGPA. CBSE uses CGPA × 9.5.

Frequently asked questions

How is CGPA calculated?

CGPA = Σ(SGPA × semester credits) ÷ Σ(credits) across all semesters — a credit-weighted average of your semester GPAs. On India's 10-point scale, each course grade (O = 10, A+ = 9, etc.) is weighted by its credits.

How do I convert CGPA to percentage?

CBSE uses Percentage = CGPA × 9.5. Most engineering universities use (CGPA − 0.75) × 10 (VTU formula) or CGPA × 10. There's no universal rule — use the conversion certificate from your own university for job and visa applications.

What is a good CGPA in engineering?

8.0+ opens most campus placements and MS admissions; 8.5+ is competitive for top recruiters and scholarships. Many companies set a 7.0 or 7.5 cutoff for eligibility. Below 6.5, focus on projects and skills to compensate.

Can I raise my CGPA in the final year?

Yes, but the leverage shrinks as completed credits accumulate. If you're at 7.5 after six semesters (~140 credits), scoring 9.5 across the final two (~45 credits) lifts you only to about 8.0. This calculator shows exactly what future SGPA you need for a target.

Is CGPA or percentage used for job applications?

Indian IT recruiters accept either but usually screen on the 10-point CGPA (common cutoffs: 6.5, 7.0, 7.5). Government jobs and foreign universities often ask for percentage, converted using your university's official formula.
