CGPA to Percentage Calculator
Convert CGPA to percentage, percentage to CGPA, GPA to percentage and SGPA to CGPA — using the correct formula for your university. Pick a profile (CBSE ×9.5, 4.0 GPA and more) or set a custom multiplier.
How the CGPA to percentage calculator works
CGPA (Cumulative Grade Point Average) is how most Indian universities, the CBSE board and many international institutions summarise your academic performance in a single number, usually on a 10-point, 5-point or 4-point scale. But job applications, higher-study forms and competitive exams like CAT often ask for a percentage — so you need an accurate conversion.
The most widely used formula in India is the CBSE 9.5 rule:
Percentage = CGPA × 9.5 • CGPA = Percentage ÷ 9.5
For a 4.0 GPA scale (common in the US), a simple approximation is Percentage = GPA ÷ 4 × 100. Because different universities publish different official tables, this calculator lets you choose a profile or type your own multiplier, so the answer matches the exact rule your institution uses rather than a one-size-fits-all guess.
Worked examples
CGPA → %: 8.2 CGPA × 9.5 = 77.9%. % → CGPA: 76% ÷ 9.5 = 8.0 CGPA. GPA → %: a 3.5 GPA on the 4.0 scale ≈ 3.5 ÷ 4 × 100 = 87.5%. SGPA → CGPA: if your four semesters are 8.1, 8.4, 7.9 and 8.6 with equal credits, CGPA = (8.1 + 8.4 + 7.9 + 8.6) ÷ 4 = 8.25.
Why 9.5 — and when it differs
CBSE arrived at the 9.5 multiplier by studying the average marks of top-scoring students across five main subjects; a perfect 10 grade point corresponded to roughly a 95% average. It’s an approximation, not an exact science, which is why universities like VTU, Anna University, Mumbai University and GTU each publish their own conversion formulas. Always confirm with your institution’s official rule — and use the custom multiplier option above if yours isn’t listed.
| CGPA (10-point) | Percentage (× 9.5) | Indicative class |
|---|---|---|
| 10.0 | 95% | Outstanding |
| 9.0 | 85.5% | Distinction |
| 8.0 | 76% | First class |
| 7.0 | 66.5% | First class |
| 6.0 | 57% | Second class |
Approximate — class boundaries depend on your university's own rules.
Frequently asked questions
How do I convert CGPA to percentage?
The common Indian formula is Percentage = CGPA × 9.5 (CBSE / 10-point). Example: 8.2 × 9.5 = 77.9%. Check your university's own rule too.
How do I convert percentage to CGPA?
Reverse it: CGPA = Percentage ÷ 9.5. So 76% ÷ 9.5 = 8.0 CGPA.
How do I convert GPA to percentage on a 4.0 scale?
A common approximation is Percentage = GPA ÷ 4 × 100, so 3.5 GPA ≈ 87.5%. Use your institution's official table when available.
What is the difference between SGPA and CGPA?
SGPA is one semester's average; CGPA is the cumulative average across all semesters. With equal credits, CGPA is the mean of your SGPAs.
Why is 9.5 used in the CGPA to percentage formula?
CBSE derived it from the average marks of high-scoring students across five subjects — a 10 grade point roughly matched a 95% average, giving 9.5. It's an approximation.
Is the conversion the same at every university?
No. CBSE uses ×9.5, but VTU, Anna University, Mumbai University and GTU use their own formulas. Pick a profile or enter a custom multiplier above.
