CGPA to Percentage: Formula for CBSE, AICTE, VTU and Mumbai University

Updated 2026-10-26 · 3 min read

Job forms, higher-study applications and scholarship portals often ask for your marks as a percentage, but your grade card shows CGPA. Each board or university has its own way to convert.

This guide lists the commonly published formulas and shows how to use the CGPA to Percentage Calculator. Remember: your university's own rule, printed on the grade card or in its ordinance, is always final.

Step by step

  1. Choose CGPA ⇄ percentage Open the calculator. The 'CGPA ⇄ percentage' tab is for converting in either direction.
  2. Pick your board or university rule In 'Board or university rule', choose CBSE (Class 10), AICTE (engineering, 10-point), VTU, Mumbai University, or 'Simple × 10'. The formula used is shown below the list.
  3. Enter your CGPA Type your CGPA (out of 10). The percentage appears next to it. You can also type a percentage to get the CGPA.
  4. Compare with other rules The tool also shows your CGPA under three other rules and a rough 4.0-scale value, so you can see how much the formula matters.
  5. Need CGPA from semester SGPAs? Switch to 'SGPA → CGPA'. Enter each semester's SGPA and credits, use Add semester for more. You get the credit-weighted CGPA, the simple average and the approximate percentage.

Common CGPA to percentage formulas

These are the formulas the calculator uses. Universities can change their rules or publish their own conversion tables, so always confirm with your grade card or university.

RuleFormulaExample
CBSE (Class 10)Percentage = CGPA × 9.58.6 CGPA = 81.7%
AICTE (engineering, 10-point)Percentage = (CGPA − 0.75) × 108.2 CGPA = 74.5%
VTUPercentage = (CGPA − 0.75) × 108.2 CGPA = 74.5%
Mumbai University (7-point+ CGPA)Percentage = 7.1 × CGPA + 118.0 CGPA = 67.8%
Simple × 10 (Anna University and many others)Percentage = CGPA × 108.2 CGPA = 82%

How CGPA is calculated from SGPA

Most universities use a credit-weighted average: CGPA = sum of (SGPA × credits) ÷ total credits. A semester with more credits counts more.

Some universities use a simple average of SGPAs. If yours does, enter the same credits for every semester and the two results will match.

Common mistakes

  • Using the CBSE 9.5 rule for a college degree. It is meant for CBSE Class 10 grades.
  • Converting each semester to percentage and averaging. Convert the final CGPA instead, unless your university says otherwise.
  • Writing a converted percentage on a form that asks for CGPA. Give exactly what the form asks for.

Questions

Which formula is correct for my university?

The one your university publishes, usually on the back of the grade card or in its ordinance. The formulas here are the commonly published ones, and your university's rule is final.

Why is CBSE CGPA multiplied by 9.5?

CBSE published the 9.5 factor for its Class 10 grading system. Use it only for CBSE Class 10 results.

How do I convert CGPA to a 4.0 GPA for studying abroad?

The calculator shows a rough 4.0-scale value, but foreign universities usually ask for an official evaluation (for example WES), so use that for applications.

How do I calculate CGPA from SGPA?

Use the SGPA → CGPA tab. Enter each semester's SGPA and credits; the tool gives the credit-weighted CGPA and the simple average.

Is this calculator official?

No. It is not connected with CBSE, AICTE, VTU, Mumbai University or any other body. It only applies the commonly published formulas.
