GWA Calculator
Calculate General Weighted Average
How to Use This GWA Calculator
If you studied in the Philippines, you know "GWA" shows up on every honors cutoff, Latin honors flyer, and grad-school checklist—yet each university seems to print grades on a slightly different numeric scale. Manually multiplying every subject by its units on a phone calculator is exactly the kind of busywork that produces a misplaced decimal before an application deadline. Enter each subject's grade and units here; the tool returns your General Weighted Average to four decimal places.
- Add subjects. Optional subject name, required grade (any numeric format your school uses), and required units.
- Calculate GWA. Press the button to see weighted average and total units counted.
- Clear and retry. Use Clear All to reset rows when modeling a new semester.
- US-style GPA? For letter grades and 4.0 credit weighting, use the GPA Calculator or College GPA Calculator.
GWA Formulas and Practical Applications
GWA treats units like credit hours—a five-unit major course pulls the average more than a two-unit PE subject, same logic as GPA elsewhere but with local grade numbers.
GWA = Σ(Grade × Units) / Σ(Units)
Worked example: Math 1.50 × 3 units = 4.50; PE 1.00 × 2 units = 2.00; sum 6.50 over 5 units → GWA 1.30 on a scale where lower is better.
Real planning uses
- Checking Latin honors cutoffs before final exams post.
- Seeing how one failed three-unit lab moves a term GWA.
- Converting handwritten load tables into one number for scholarship forms.
Standard Units and Conversion Tables
Philippine institutions use several numeric systems—the calculator does not convert between them; you enter grades as your school reports them:
| System | Typical range | Direction |
|---|---|---|
| 1.00 – 5.00 | UP and many state universities | Lower is better; 3.00 often passing |
| 4.00 – 1.00 | DLSU, ADMU, and others | Higher is better; 1.00 often passing |
| Percentage | ~75% passing at some schools | Higher is better |
Units are subject credit loads (3-unit lecture, 5-unit lab, etc.). Always match the units on your curriculum checklist.
Frequently Asked Questions
What is GWA in the Philippines?
General Weighted Average—your unit-weighted mean grade across enrolled subjects for a term or cumulative record.
How do you compute GWA?
Multiply each grade by its units, add, divide by total units—the formula shown above.
Does lower GWA always mean better grades?
On 1.00–5.00 scales, yes—1.00 is excellent. On 4.00–1.00 inverted scales, higher numbers are better. Know which table your university publishes.
Can I use percentage grades?
Yes—enter the numeric values exactly as listed on your portal; the math is the same.
Is this my official transcript GWA?
No. Confirm with your registrar. See all grade calculators for related tools.
