Calculate your Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA) with our easy-to-use calculator
Understanding GPA and CGPA
GPA (Grade Point Average) and CGPA (Cumulative Grade Point Average) are standard metrics used by educational institutions to measure academic performance. While GPA typically refers to the average for a single semester, CGPA represents the cumulative average across all semesters or courses.
These metrics are crucial for academic assessment, scholarship eligibility, and even job applications in some cases. Different countries and institutions may use slightly different grading scales, but the 4.0 scale is widely recognized internationally.
Our calculator uses the standard 4.0 scale, which is the most common grading system in North American universities and many educational institutions worldwide. If your institution uses a different scale, you may need to convert your grades accordingly.

GPA Calculation Process
Step-by-Step Calculation
- Convert each grade to its numerical equivalent (e.g., A = 4.0)
- Multiply each course’s grade points by its credit hours
- Sum all the grade points × credit hours values
- Sum all the credit hours attempted
- Divide the total grade points by the total credit hours

Example Calculation
Suppose a student has the following grades:
- Mathematics (4 credits): A (4.0)
- History (3 credits): B+ (3.3)
- Biology (4 credits): A- (3.7)
GPA = [(4.0 × 4) + (3.3 × 3) + (3.7 × 4)] ÷ (4 + 3 + 4) = (16 + 9.9 + 14.8) ÷ 11 = 40.7 ÷ 11 = 3.70

| Grade | Points | Percentage Range |
|---|---|---|
| O (Outstanding) | 10 | 90-100% |
| A+ | 9 | 80-89% |

| E | 3 | 20-29% |
| F | 0 | Below 20% |
Custom Grading Scale
Some institutions use custom grading scales. These can be configured in the GPA calculator by specifying the grade values.
Creating a Custom Scale
To create a custom scale, use the format: Grade:Value, Grade:Value
Example: A:4.0, A-:3.7, B+:3.3, B:3.0, B-:2.7, C+:2.3, C:2.0, D:1.0, F:0.0

Understanding CGPA
What is CGPA?
Cumulative Grade Point Average (CGPA) is the average of Grade Points obtained in all semesters, excluding additional courses where a grade is not awarded.
Example CGPA Calculation
Suppose a student has:
- Semester 1: GPA 3.70, 15 credits
- Semester 2: GPA 3.90, 16 credits
- Semester 3: GPA 3.80, 14 credits
CGPA = [(3.70 × 15) + (3.90 × 16) + (3.80 × 14)] ÷ (15 + 16 + 14) = (55.5 + 62.4 + 53.2) ÷ 45 = 171.1 ÷ 45 = 3.80

Frequently Asked Questions
GPA (Grade Point Average) refers to the average grade points earned in a single semester, while CGPA (Cumulative Grade Point Average) is the average of all GPA scores across all semesters. CGPA provides an overall measure of academic performance throughout a program.
To improve your GPA:
- Focus on courses with higher credit values
- Retake courses where you received low grades (if allowed)
- Seek academic support and tutoring
- Improve study habits and time management
- Balance your course load between challenging and manageable courses
Typically, pass/fail courses do not affect GPA. If you pass, you receive the credit hours but no grade points. If you fail, you may not receive credit, but it usually doesn’t negatively impact your GPA. However, policies vary by institution, so check with your school.
Conversion methods vary, but a common approach is:
- Determine the maximum GPA scale of your institution (e.g., 10.0, 100%)
- Divide your GPA by the maximum scale
- Multiply by 4.0
Example: If you have a GPA of 8.5 on a 10.0 scale: (8.5 ÷ 10) × 4 = 3.4 on a 4.0 scale.
A “good” GPA depends on context:
- Generally, a GPA of 3.0 or above is considered good
- For competitive programs, 3.5 or higher may be expected
- Graduate schools often look for GPAs of 3.0-3.5 or higher
- Honors programs may require 3.5+
Remember that context matters—some programs are known for stricter grading.
Weighted GPA gives extra points for advanced courses like Honors, AP, or IB classes. For example, while a regular A might be worth 4.0, an A in an AP class might be worth 5.0. This system rewards students for taking more challenging courses.
