How to Calculate GWA Manually: A Step-by-Step Guide for Filipino Students
For students in the Philippines, knowing how to calculate your General Weighted Average (GWA) is an essential skill, especially when tracking your academic performance or applying for scholarships and academic honors. While schools and universities often compute this for you, understanding the manual process gives you better control over your grades.
In this article, we’ll walk you through the step-by-step process of manually calculating your GWA, explain its significance, and provide helpful tips to ensure accuracy.
What is GWA?
The General Weighted Average (GWA) is a numerical representation of a student’s academic performance across all subjects. It’s calculated by assigning weights to your grades based on the credit units of each subject. The resulting figure represents your overall performance, with a lower GWA indicating better results.
In the Philippines, the GWA is commonly used to determine academic honors, scholarships, and eligibility for certain academic programs.
Why Should You Know How to Calculate GWA Manually?
- Accuracy: While schools automate the process, understanding the manual calculation ensures there are no errors.
- Self-Assessment: Track your performance in real-time and identify areas for improvement.
- Scholarships and Awards: Many scholarship programs require a minimum GWA. Knowing how to compute it ensures you meet the criteria.
Steps to Calculate GWA Manually
Step 1: Gather Your Grades and Credit Units
Start by listing all your subjects, their corresponding grades, and the credit units for each subject. Here’s an example table:
| Subject | Grade | Credit Units |
|---|---|---|
| Mathematics | 88 | 3 |
| English | 92 | 3 |
| Science | 85 | 4 |
| History | 90 | 2 |
| Physical Education | 95 | 1 |
Step 2: Multiply Grade by Credit Units for Each Subject
Next, calculate the weighted grade for each subject by multiplying the grade by its credit units.
Example Calculation:
- Mathematics: 88×3=264
- English: 92×3=276
- Science: 85×4=340
- History: 90×2=1809
- Physical Education: 95×1=95
Step 3: Add All Weighted Grades
Sum up all the weighted grades you calculated in Step 2.
264+276+340+180+95=1155
Step 4: Add All Credit Units
Add the total credit units of all your subjects.
3+3+4+2+1=13
Step 5: Divide the Total Weighted Grade by the Total Credit Units
Finally, divide the sum of weighted grades by the sum of credit units to get your GWA.
GWA=131155=88.85
So, the GWA for this example is 88.85.

Key Tips for Accuracy
- Double-Check Your Data: Ensure that the grades and credit units you’ve recorded are correct.
- Follow Your School’s Grading System: Some schools use different grading scales (e.g., 1.0–5.0 or percentage-based). Adjust your calculation accordingly.
- Weight Elective Subjects Appropriately: Some schools may not include minor subjects like Physical Education in the GWA. Verify your institution’s policy.
- Use a Calculator: While the calculations are simple, using a calculator minimizes errors.
Common Mistakes When Calculating GWA
- Forgetting Credit Units: Always remember that credit units determine the weight of a subject. Ignoring this will lead to incorrect results.
- Mixing Up Grades: Double-check the grades for each subject before multiplying them by their credit units.
- Skipping Minor Subjects: Unless explicitly stated, include all subjects in your computation.
Understanding the GWA Scale in the Philippines
Different schools may have varying interpretations of GWA scales. Below is a general guide:
| GWA Range | Interpretation |
|---|---|
| 1.0 – 1.75 | Excellent (With Honors) |
| 1.76 – 2.25 | Very Good |
| 2.26 – 2.75 | Good |
| 2.76 – 3.0 | Passing |
| 3.1 – 5.0 | Failing |
Ensure you know whether your school uses a percentage system (e.g., 75-100%) or the 1.0–5.0 scale to avoid confusion.
Benefits of Maintaining a Good GWA
- Scholarship Eligibility: Many institutions and private organizations require a specific GWA for scholarships.
- Academic Honors: Graduating with honors boosts your academic profile.
- Employment Opportunities: A high GWA can enhance your resume when applying for internships or jobs.
- Self-Improvement: Tracking your GWA motivates you to excel academically.
Real-Life Applications of GWA
- Scholarship Applications: Government and private organizations often require applicants to have a minimum GWA (e.g., CHED scholarships in the Philippines).
- Transferring Schools: If you’re transferring to a new school, your GWA is a key requirement.
- Graduate Studies: Universities offering postgraduate programs assess applicants based on their undergraduate GWA.
Quick Reference Table for GWA Calculation
| Step | Action | Example |
|---|---|---|
| Step 1 | List grades and credit units | Math: 88, 3 units |
| Step 2 | Multiply grade by credit units | Math: 88×3=264 |
| Step 3 | Add all weighted grades | 264+276+340+180+95=1155 |
| Step 4 | Add total credit units | 3+3+4+2+1=13 |
| Step 5 | Divide total weighted grades by total credit units | 1155/13=88.85 |
Conclusion
Calculating your GWA manually is a straightforward yet valuable skill for Filipino students. By following the step-by-step guide outlined above, you can accurately compute your academic performance and use it to plan your academic goals. Remember to double-check your data, understand your school’s grading system, and include all relevant subjects in your calculations.
With a solid understanding of your GWA, you’re better equipped to excel academically, apply for scholarships, and achieve your academic aspirations.
