CGPA to Percentage Calculator

How to Use the CGPA Calculator

1. Enter your CGPA on the scale used by your institution (commonly 10-point or 4-point).
2. Confirm the conversion method that matches your university guidelines.
3. Calculate to obtain the equivalent percentage.
4. Prefer the official rule from your registrar if it differs from the default formula.

Enter your CGPA and choose a conversion method: “10-point scale × 9.5”, “10-point scale × 10” or “4.0 scale → percentage (× 25)”. The CGPA cannot be higher than the top of the scale you chose (10 or 4), or an error appears. The result shows the percentage to two decimal places and names the method used. Check your university’s official rule if the number will be submitted.

CGPA Calculator Formula Explained

A frequently cited 10-point formula is percentage equals CGPA times 9.5. Some institutions use CGPA times 10 or publish their own linear mapping. On a 4.0 scale, percentage approximations vary more widely and are best taken from the issuing university. The calculator makes the arithmetic instant; policy compliance remains your responsibility when the number is official.

The calculator uses one of three fixed rules. The first 10-point option multiplies CGPA by 9.5, and the second multiplies it by 10, which some universities use. The 4.0 option multiplies CGPA by 25, so 4.0 equals 100%. Many universities publish their own table, and those results can differ from these simple formulas.

CGPA Calculator Example Calculation

A CGPA of 8.4 on a 10-point scale using the ×9.5 rule converts to 79.8%. A 3.6 on a 4.0 scale gives 90.00% with the simple ×25 option, but your university may publish a different mapping. Always prefer the conversion printed on your transcript when applying to universities or employers.

Worked example: enter 8.4 and choose “10-point scale × 9.5”. The result is 79.80%. Enter 7.2 with the same method and the result is 68.40%. Choose “4.0 scale → percentage (× 25)” and enter 3.6, and the result is 90.00%.

When to use this tool

Use this for quick estimates on applications, CVs and mobility programmes (study-abroad programmes, master’s admissions). Official submissions should follow the issuing institution’s rule.
