The Math

How TTU GPA Is Calculated

Texas Tech multiplies each grade point by credit hours to get quality points, then divides total quality points by total graded hours.

TTU GPA Formula
\[ \text{GPA} = \frac{\displaystyle\sum \text{Quality Points}}{\displaystyle\sum \text{Graded Hours}} = \frac{\displaystyle\sum (\text{Grade Point} \times \text{Credit Hours})}{\displaystyle\sum \text{Credit Hours}} \]
Quality PointsGrade point value × credit hours for each course
Graded HoursTotal graded credit hours (excludes P, CR, I, W, etc.)

📝 Worked Example

An example using four courses, following the official TTU advising method:

CourseCredit HoursGradeGrade PointQuality Points
ENGL 13013.0B3.003 × 3.00 = 9.00
MATH 15505.0A4.005 × 4.00 = 20.00
RRP 11001.0A4.001 × 4.00 = 4.00
HIST 23003.0C2.003 × 2.00 = 6.00
Total12.0——39.00

Plugging into the formula:

\[ \text{GPA} = \frac{39.00}{12.0} = \mathbf{3.25} \]

Convert GPA → Percentage

Enter any TTU GPA between 0.0 and 4.0.

The Conversion Formula

Texas Tech uses a 4.0 scale, so:

\[ \text{Percentage} = \text{GPA} \times 25 \quad \text{or equivalently} \quad \text{Percentage} = \left(\frac{\text{GPA}}{4.0}\right) \times 100 \]

Example: If your GPA is 3.5, then Percentage = 3.5 × 25 = 87.50%.
