Simple vs Weighted Mode
In Simple mode every subject contributes equally to the final average. In Weighted mode a weight field appears for each subject — enter any positive number (e.g. credit hours). The weighted average is calculated as the sum of (percentage × weight) divided by the total weight.
Tips
- Leave the
Out offield at 100 to enter percentages directly - Use raw point totals (e.g. Score 45, Out of 60) and the tool handles the conversion
- Subjects with no score entered are skipped and do not affect the average
- Weighted GPA is shown alongside simple GPA when Weighted mode is active
FAQ
How is GPA calculated?
Each subject's percentage is converted to a letter grade and then to its 4.0 GPA point. The overall GPA shown is the arithmetic mean of all individual subject GPA points, not a weighted sum.
What happens if I leave some rows empty?
Rows without both a score and a max score value are skipped automatically. They do not count toward the average or the subject breakdown.
Can I use raw points instead of percentages?
Yes. Enter the raw score (e.g. 45) in the Score field and the total possible points (e.g. 60) in the Out of field. The tool computes the percentage internally: 45 / 60 = 75%.
How does weighted mode work?
Assign each subject a weight equal to its credit hours or relative importance. The weighted average is sum(percentage * weight) / sum(weight). A subject with weight 3 counts three times as much as one with weight 1.
Is this tool suitable for non-US grading systems?
The letter grades and GPA use the standard US scale. If your institution uses a different scale the raw percentage column in the breakdown still gives you the number to map to your local grades.
