Compute Overall Percentage and CGPA from Multiple Subjects
Students often need to calculate their overall percentage and CGPA (Cumulative Grade Point Average) based on marks obtained across multiple subjects. While schools and universities provide grading systems, calculating the final result manually can sometimes be confusing.
The Percentage & CGPA Calculator on CoolDev.Tools allows students to enter marks for multiple subjects and instantly compute their overall percentage and CGPA.
The tool supports configurable CGPA scales, such as the commonly used 9.5 multiplier used in CBSE boards, as well as other grading scales used by universities and educational institutions.
With a simple interface and instant calculations, the calculator helps students evaluate their academic performance quickly and accurately.
Because the tool runs directly in your browser, you can perform calculations instantly without using spreadsheets or complicated formulas.
What is Percentage in Academic Grading?
Percentage represents the proportion of marks obtained out of the total marks possible.
The percentage formula is:
Percentage = (Total Marks Obtained / Total Maximum Marks) × 100
Example:
Total Marks Obtained = 425
Maximum Marks = 500
Percentage calculation:
(425 / 500) × 100 = 85%
Percentage is commonly used in schools and colleges to represent overall academic performance.
What is CGPA?
CGPA (Cumulative Grade Point Average) is a grading system used by many educational institutions to evaluate a student's academic performance.
Instead of percentages, grades are converted into grade points, which are averaged to calculate the CGPA.
The CGPA system is commonly used in:
- CBSE schools
- universities
- engineering colleges
- international academic institutions
CGPA typically ranges from 0 to 10 in many grading systems.
CGPA to Percentage Conversion
In some education boards such as CBSE, percentage can be estimated from CGPA using a conversion factor.
Example formula:
Percentage = CGPA × 9.5
Example:
CGPA = 8.4
Percentage = 8.4 × 9.5 = 79.8%
Different institutions may use different conversion factors, which is why the calculator allows configurable CGPA scales.
