Stony Brook University (SBU) GPA Calculator

Our **Stony Brook University GPA Calculator** is designed to be straightforward and highly accurate, helping you project your academic standing with ease. Here’s a simple, step-by-step guide on how to use this powerful tool:

1. Input Your Course Information:

   For each course you've taken or are currently taking, you'll enter three key pieces of information:

   • Course Code (Optional): Like "CSE 101" or "MTH 103". This helps you organize your entries, but it's not used in the GPA calculation itself.
   • Credits: The number of credit hours for the course (e.g., 3.0, 4.0). Accuracy here is crucial as credits directly impact your GPA.
   • Grade: Select the letter grade you received (or expect to receive) from the convenient dropdown menu (e.g., A, B+, C-). Our calculator understands Stony Brook's plus/minus grading system.
2. Add More Courses as Needed:

   Have multiple courses for the semester? No problem! Simply click the **"Add Another Course"** button. A new row of input fields will appear, allowing you to add as many courses as you need for a complete semester GPA calculation.

3. Factor in Your Previous GPA (Optional for Cumulative GPA):

   If you want to see your projected **cumulative GPA** (your overall GPA across all semesters at Stony Brook), check the box labeled **"Include previous GPA?"**. Once checked, two new fields will appear:

   • Previous Cumulative GPA: Enter your overall GPA from all prior semesters.
   • Previous Cumulative Credits: Input the total number of credit hours you've earned from all previous semesters.

   This feature is essential for understanding your long-term academic progress at Stony Brook University.

4. Calculate Your GPA:

   Once all your course information is entered and previous GPA details (if applicable) are provided, click the prominent **"CALCULATE GPA"** button. The calculator will instantly process your data.

5. Review Your Results:

   Immediately after calculation, you'll see your results clearly displayed:

   • Semester GPA: This is your GPA for the courses you just entered.
   • Cumulative GPA: If you included previous GPA, this is your projected overall GPA. Otherwise, it will match your Semester GPA.

   A visual bar chart will also appear, illustrating your total Quality Points and Credit Hours for the semester, providing a quick overview of your academic performance.

This tool is specifically designed to adhere to Stony Brook's official grading policies. It automatically excludes non-numeric grades (like Pass/Fail, Withdrawals, Incompletes, etc.) and ensures that only the latest attempt of a repeated course is factored into your GPA, just as Stony Brook University does.

The Grade Point Average (GPA) is a numerical representation of your academic performance. It's calculated by assigning a numerical "quality point" to each letter grade and then averaging these points based on the credit hours of each course. Here are the formulas used by this Stony Brook GPA calculator:

1. Semester GPA Formula:

Semester GPA = (Total Quality Points for Semester) / (Total Credit Hours for Semester)
Where: Total Quality Points for Semester = Sum of (Grade Point Value × Credits for Each Course)

In simple terms: For each course, you multiply its credit hours by the numerical value of its grade (e.g., an 'A' is 4.00, a 'B+' is 3.33). You sum these up for all your courses in the semester to get your "Total Quality Points." Then, you divide this sum by the total number of credit hours you took in that semester.

2. Cumulative GPA Formula:

Cumulative GPA = ((Previous GPA × Previous Credits) + (Semester Quality Points)) / (Previous Credits + Semester Credits)

In simple terms: This formula combines your past academic performance with your current semester's results. You multiply your previous overall GPA by your total previous credit hours to get your "Previous Quality Points." You then add this to the "Semester Quality Points" you just calculated. This grand total of quality points is then divided by the sum of your previous total credit hours and your current semester's credit hours.

Stony Brook University officially rounds GPAs to three decimal places (e.g., 3.200).

• How many decimals does Stony Brook round to? Stony Brook University typically rounds official GPAs to three decimal places, for example, 3.200 or 3.875.
• Do retaken course grades average? No, when a course is repeated at Stony Brook, only the most recent grade earned for that course is counted in your GPA calculation. Previous attempts for the same course are excluded.
• What GPA is required for good academic standing? Generally, a minimum cumulative GPA of 2.0 is required for undergraduate students to maintain good academic standing at Stony Brook University.
• Can my GPA exceed 4.0 at Stony Brook? No, while internal calculations might sometimes result in a value slightly above 4.0, the official maximum GPA at Stony Brook University is capped at 4.00.
• Are Pass/Fail courses included in GPA calculation? No, grades such as P (Pass), W (Withdrawal), NC (No Credit), NR (Not Reported), and I (Incomplete) do not contribute to your GPA calculation at Stony Brook.
• What happens if I receive an Incomplete (I) grade? An Incomplete (I) grade indicates that coursework is unfinished due to extenuating circumstances. If not resolved by the designated deadline, an 'I' grade may convert to an 'I/F', which is equivalent to an 'F' (0.00) in your GPA calculation.
