CGPA (Cumulative Grade Point Average) sums up your academic performance across all semesters into one number, typically on a 4.0 or 10.0 scale. Percentages, though, are often required for applications, transcripts, or just to understand your standing in a more familiar way. This guide explains how to convert CGPA to percentage and makes it easy with our calculator. Let’s get started!
What Is CGPA?
CGPA combines your Semester Grade Point Averages (SGPAs) into a single score. It’s calculated by factoring in your grade points and credits across all semesters. Whether your school uses a 4.0 scale (like many U.S. institutions) or a 10.0 scale (common in India and elsewhere), CGPA reflects your overall achievement.
Why Convert CGPA to Percentage?
Not everyone speaks “CGPA.” Employers, universities, or scholarship boards might ask for a percentage instead. Converting it helps you communicate your grades clearly—and saves you from doing math by hand. A calculator makes it instant and accurate!
How CGPA Is Converted to Percentage
Conversion depends on your grading scale. Here’s the breakdown:
-
10.0 Scale:
Percentage = CGPA × 10
Example: CGPA of 8.5 = 8.5 × 10 = 85% -
4.0 Scale (Approximate):
Percentage = CGPA × 25
Example: CGPA of 3.2 = 3.2 × 25 = 80%
Note: Some schools adjust this (e.g., 4.0 = 90-100%). Check your institution’s rule.

Examples of CGPA to Percentage Conversion
Let’s see it in action:
-
Example 1: 10.0 Scale
CGPA = 9.2
Percentage = 9.2 × 10 = 92% -
Example 2: 4.0 Scale
CGPA = 3.6
Percentage = 3.6 × 25 = 90% (assuming standard approximation) -
Example 3: Custom Formula (e.g., India CBSE Adjustment)
CGPA = 8.0
Percentage = 8.0 × 9.5 = 76% (some boards use 9.5 instead of 10—check yours!)

CGPA to % Conversion Tips
-
Know Your Scale: Use 10.0 or 4.0 correctly—mixing them gives nonsense results.
-
Check School Rules: Some tweak the formula (e.g., CGPA × 9.5 or a 4.0 scale with ranges). Verify with your institution.
-
Round Smartly: If it’s 89.75%, decide if you need 89% or 90% based on context.
FAQs About CGPA to Percentage
-
Does CGPA include failed semesters?
Yes, every semester’s grades—including zeros—count toward CGPA. -
Why is my percentage lower than expected?
You might be using the wrong formula. A 10.0 CGPA with × 9.5 gives 95%, not 100%. Check your school’s method. -
Can I convert percentage back to CGPA?
Sure! Divide by the factor: 85% ÷ 10 = 8.5 (10.0 scale) or 80% ÷ 25 = 3.2 (4.0 scale). -
What if my CGPA is on a 7.0 scale?
Find your school’s conversion rule (e.g., × 14.29 might work for 7.0 = 100%). Use a custom calculator option if available. -
Is the calculator’s result official?
It’s accurate for standard formulas, but always confirm with your school for official use.
