Example Data Table
| Course | Credits | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| AMS 151 | 4 | A- | 3.67 | 14.68 |
| WRT 102 | 3 | B+ | 3.33 | 9.99 |
| CHE 131 | 4 | B | 3.00 | 12.00 |

Example GPA: 43.66 quality points divided by 14 credits equals 3.119.
Formula Used
Quality Points = Grade Points × Course Credits
GPA = Total Quality Points ÷ Total GPA Credits
The calculator first converts each letter grade into grade points. It then multiplies those points by course credits. After that, it adds all quality points. It also adds all credits that count toward GPA. Excluded records are skipped in the GPA average.
How To Use This Calculator
Enter your current cumulative GPA and completed credits if you want a cumulative estimate. Leave them blank for a semester-only GPA. Add each course name, credit value, and expected grade. Choose whether the course should count toward GPA. Press the calculate button. Use CSV or PDF buttons to save the scenario.
Understanding This GPA Calculator
A Stony Brook GPA calculator helps you review semester performance before grades become final. It converts each letter grade into grade points. Then it weights those points by course credits. This matters because a four credit class affects GPA more than a one credit class.
Why Credit Weight Matters
Every course creates quality points. Quality points equal grade points multiplied by credits. A course with an A and three credits gives twelve quality points. A course with a B and four credits also gives twelve quality points. The calculator adds all quality points. It also adds all GPA credits. The final GPA is total quality points divided by total GPA credits.
Advanced Planning Options
This page supports current courses, prior cumulative records, excluded grades, and target planning. You can enter completed credits and your current cumulative GPA. The tool adds new quality points to old quality points. It then shows an estimated cumulative GPA. You can also enter a target GPA. The calculator estimates the GPA needed in planned future credits. This helps you plan realistic next steps.
Grade Exclusions
Some records do not affect GPA. Pass, no credit, satisfactory, unsatisfactory, withdrawal, and no record grades are excluded here. They can still matter for requirements. Always check official advising rules before making academic decisions.
Using Results Wisely
The result is an estimate for planning. It is not an official university transcript. Official records can include repeat rules, incomplete changes, transfer rules, academic standing rules, and program exceptions. Use the result to prepare questions for an adviser. It can also help compare different grade scenarios.
Reports And Records
CSV and PDF exports help you keep a clean record. You can save the report after each scenario. You can also print it before advising meetings. Keep course names clear. Enter credits carefully. Small credit errors can change the final number.
Better Semester Decisions
A GPA calculator is most useful before deadlines. Try best case, expected, and risk scenarios. Review the courses with the largest credit weight first. Strong performance in those courses has the biggest effect. Use the target field to see how future credits can improve your average. Check totals before copying results into personal planning records.
FAQs
Does this calculator use Stony Brook grade points?
Yes. It uses the common Stony Brook point scale shown in the calculator. Letter grades are multiplied by credits to create quality points.
Can I calculate only one semester?
Yes. Leave current cumulative GPA and completed credits blank. The result will show the GPA for the courses entered.
Can I estimate my cumulative GPA?
Yes. Enter your current cumulative GPA and completed GPA credits. The calculator combines prior quality points with new course quality points.
Do P, NC, S, U, W, NR, and R affect GPA?
No. This calculator excludes those records from GPA credits and quality points. They may still affect requirements, progress, or advising rules.
How are quality points calculated?
Quality points equal grade points multiplied by course credits. For example, a B in a four credit course gives twelve quality points.
Can I exclude a repeated or planned course?
Yes. Set “Use in GPA” to “No” for a course. The credits will be tracked as excluded and skipped from GPA math.
Is this an official GPA result?
No. It is an estimate for planning. Official GPA records depend on the university transcript, registrar rules, and program policies.
Why add CSV and PDF exports?
Exports help you save scenarios, compare plans, and prepare for adviser meetings. They also make records easier to print or archive.
