Official GPA Calculator
Enter each course, credit hours, and final letter grade. The calculator uses a standard 4.0 scale and returns your semester GPA. You can also estimate your updated cumulative GPA using prior credits and GPA.

What this official GPA calculator does
This official GPA calculator is designed to help students quickly compute their grade point average with transparency. Instead of guessing or using an unclear tool, you can enter your real course load, apply credit hours, and instantly see how each class contributes to your GPA outcome.
Because most schools weight courses by credits, this calculator follows the standard weighted formula. A 4-credit class affects your GPA more than a 1-credit class. That makes this format useful for college, university, and many high school transcript models.
How GPA is calculated
The core formula
GPA = Total Quality Points ÷ Total Attempted Credits
Quality points are found by multiplying each course’s grade points by that course’s credits. For example, a B (3.0) in a 3-credit class gives you 9.0 quality points.
Common letter-grade scale (4.0 system)
- A = 4.0
- A- = 3.7
- B+ = 3.3
- B = 3.0
- B- = 2.7
- C+ = 2.3
- C = 2.0
- C- = 1.7
- D+ = 1.3
- D = 1.0
- D- = 0.7
- F = 0.0
Note: Some institutions use slight variations (such as A+ = 4.0 or 4.3). Always confirm your school’s official policy in the catalog or registrar handbook.
Step-by-step example
Suppose your semester includes:
- Biology: 4 credits, B+ (3.3)
- English: 3 credits, A- (3.7)
- Statistics: 3 credits, B (3.0)
- Art History: 2 credits, A (4.0)
Quality points:
- Biology: 4 × 3.3 = 13.2
- English: 3 × 3.7 = 11.1
- Statistics: 3 × 3.0 = 9.0
- Art History: 2 × 4.0 = 8.0
Total quality points = 41.3, total credits = 12, so GPA = 41.3 ÷ 12 = 3.44.
Semester GPA vs cumulative GPA
Semester GPA
This reflects only your current term. It is useful for tracking immediate progress and semester-based goals.
Cumulative GPA
This combines all eligible coursework completed so far. It is the number most often reviewed for scholarships, probation, transfer admissions, and graduate applications.
Use the optional cumulative fields in the calculator to estimate your new cumulative GPA after finalizing this term’s grades.
Best practices for accurate results
- Enter official final grades, not midterm estimates.
- Use exact credits listed on your transcript or registration portal.
- Exclude pass/fail courses unless your school converts them to grade points.
- Check whether repeated courses replace or average prior grades at your institution.
- Round only at the end (most schools round to 2 or 3 decimals).
Frequently asked questions
Do withdrawals (W) count in GPA?
Usually no, but they may still appear on your transcript. Institutional policy can differ.
Do AP, IB, or dual enrollment classes count?
They may count toward credits and sometimes GPA, depending on how your school posts transfer or advanced credits.
What if my school uses weighted honors/AP GPA?
This calculator uses a standard unweighted 4.0 model. If your school adds extra points for honors/AP courses, use your school’s custom scale and conversion policy.
Final reminder
This tool gives a reliable estimate and is ideal for planning. For truly official GPA reporting, always defer to your institution’s registrar and transcript evaluation rules.
