How to Compute GWA: Step-by-Step Guide for Students PH

To compute GWA (General Weighted Average), multiply each subject grade by its units, add the results, then divide by total units. Example: Math (3 units, 1.75), English (3 units, 2.0), PE (2 units, 2.5). GWA = (5.25 + 6 + 5) ÷ 8 = 2.03. This weighted system ensures major subjects affect your GWA more than minor ones.

What is GWA?

GWA (General Weighted Average) is the overall measure of a student’s academic performance in the Philippines. Unlike a simple average, GWA weights each subject based on credit units.

• Why it matters:
  • Scholarships often require a minimum GWA.
  • Latin honors (Cum Laude, Magna, Summa) are based on GWA.
  • Course shifting in universities like UP or PUP checks your GWA/CWA.

Formula for GWA

The formula is simple:

\[ \text{GWA} = \frac{\sum ( \text{Grade} \times \text{Units} )}{\sum (\text{Units})} \]

• Grade = the mark you earned (e.g., 1.75, 2.0, 2.5)
• Units = the credit weight of the subject

Why units matter: Major subjects (3–5 units) affect your GWA more than light subjects like PE (1–2 units).

Step-by-Step Guide (Manual Computation)

• List all subjects with units and grades.
• Multiply grade × units for each subject.
• Add all results (Σ of products).
• Divide by total number of units.

Example

• Total Units = 12
• Total Weighted Score = 25.25

GWA=25.25÷12=2.10

Your GWA is 2.10

How to Compute GWA in Senior High School (SHS)

In SHS, computation is simpler because many subjects carry the same weight.

• Step 1: Convert percentage grade to its equivalent (based on your school’s system).
• Step 2: Multiply by units (if given).
• Step 3: Apply the same GWA formula.

Example (ABM Strand, equal weight):

If you scored 90 (Math), 88 (English), 85 (Oral Communication), then your average is around 87.7, which becomes your GWA equivalent depending on the school’s conversion table.

How to Compute GWA in College

In college, credit units matter most. A failing or low grade in a 5-unit subject affects your GWA much more than in a 2-unit subject.

Example

• Total Units = 14
• Total Weighted Score = 29.25

GWA=29.25÷14=2.09

College GWA = 2.09

How to Compute GWA in Excel

You can use Excel to speed things up:

• List grades in one column, units in another.
• Use the formula:

=SUMPRODUCT(A2:A10, B2:B10)/SUM(B2:B10)

Where:

• A2:A10 = range of grades
• B2:B10 = range of units

This will instantly compute your GWA.

How to Compute GWA Using Online Tools

Manual and Excel methods work, but they take time. For quick and error-free results, use a tool like our GWA Calculator.

• Enter grades + units.
• Click calculate.
• Get instant GWA.

This works for SHS and College systems.

Common Mistakes Students Make in Computing GWA

Why GWA Matters for Students

• Scholarships – often require 1.75 or better.
• Latin Honors – Cum Laude (≤1.75), Magna Cum Laude (≤1.5), Summa Cum Laude (≤1.25), depending on school.
• Shifting Programs – used in UP, PUP, and others to evaluate transfer eligibility.
• Academic Standing – low GWA may result in probation or disqualification.

GWA vs GPA vs CWA

• GWA: Used in the Philippines, weighted average of all subjects.
• GPA: Used internationally, often semester-based and on a 4.0 scale.
• CWA: Curriculum Weighted Average, counts only subjects required in your program.
