No rule is applied until you select a university — we never guess a formula.

This guide explains exactly how to convert CGPA into percentage, step by step, the way your university actually expects it to be done. You can follow the steps by hand, or use the free CGPA to percentage calculator at the top of this page and let it substitute your numbers while you read.

Step 1: Start with your exact CGPA

Take the CGPA from your latest grade card or calculate it from your semester SGPAs with the SGPA to CGPA calculator. Copy it exactly — 8.46, not “about 8.5”. Rounding before you convert quietly changes the final percentage, sometimes by a full mark, and every step after this one inherits that error.

Step 2: Select your university before any formula

There is no single Indian formula for converting CGPA into percentage. Each university publishes its own conversion in an official notification, and two students with identical CGPAs can legitimately get different percentages. In the calculator above, VTU's 2022 scheme uses Percentage = CGPA × 10 while VTU's 2015–2018 schemes use (CGPA − 0.75) × 10, and JNTUH uses (CGPA − 0.5) × 10 — every rule linked to the official university document it comes from. Mumbai University is the exception: it repealed formula conversion in January 2026, so its calculator entry explains the marks-based process instead.

Step 3: Apply the formula with your numbers

Worked example: your CGPA is 8.20. Under VTU's 2015–2018 scheme rule: (8.20 − 0.75) × 10 = 74.50%. Under VTU's 2022 scheme rule: 8.20 × 10 = 82.00%. Under JNTUH's official rule: (8.20 − 0.5) × 10 = 77.00%. Same student, same CGPA, three different answers — that gap is exactly why step 2 comes before step 3. The calculator writes this substitution out in full so you can check it line by line.

Step 4: Check the official source

Every result on this site names the rule, the scheme it applies to, and links the official university document it was taken from — VTU's Regulations 2022, JNTUH's Academic Regulations, SPPU's Circular 332/2020, and so on. Open the source, confirm your batch is covered by it, and keep its name beside your percentage. That one habit makes any converted figure defensible in a document-verification queue.

Step 5: Confirm for formal use

For admissions, scholarships and employers, match the rule to your regulation year and, where the application asks for it, submit the percentage or CGPA printed or certified by your university. If your computed figure and your transcript ever disagree, the transcript wins — contact your examination cell with both numbers.

Frequently asked questions

How to convert CGPA into percentage?

What percentage is 8.0 CGPA?

It depends on your university's official rule: VTU 2022 scheme gives 80.00 percent, VTU's 2015–2018 scheme rule gives 72.50 percent, and JNTUH's official rule gives 75.00 percent. Select your university and scheme in the calculator — the official source is linked with the result.

Can I convert CGPA into percentage without selecting a university?

You can do rough mental maths, but it is not reliable. Without a university rule there is no correct single answer, which is why the calculator asks you to select your university first.

Use the SGPA to CGPA calculator to combine your semester SGPAs, then return here and convert that CGPA into percentage.
