How to use the GPA calculator
- For each class, choose your letter grade and enter its credit hours. Course names are optional.
- Click + Add class for more rows. Rows without credits are ignored.
- To get an updated cumulative GPA, open "Include previous semesters" and enter your current GPA and total credits so far.
The GPA formula
GPA = Σ (grade points × credits) ÷ Σ credits
Example: an A in a 3-credit class (12 points), a B+ in a 4-credit class (13.2 points), a B in a 3-credit class (9 points) and an A− in a 3-credit class (11.1 points) total 45.3 grade points over 13 credits. That's a semester GPA of 3.48.
To combine with previous semesters: if your GPA was 3.2 over 45 credits (144 grade points), your new cumulative GPA is (144 + 45.3) ÷ (45 + 13) = 3.26.
Grade point scale
| Letter | Points | Typical % |
|---|---|---|
| A / A+ | 4.0 | 93–100 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C− | 1.7 | 70–72 |
| D+ / D / D− | 1.3 / 1.0 / 0.7 | 60–69 |
| F | 0.0 | Below 60 |
Percentage cut-offs vary between schools and instructors. Always check your syllabus.
How to raise your GPA
- Focus on high-credit classes: they move your GPA the most.
- Raise your GPA early: the more credits you've completed, the harder it is to move a cumulative GPA.
- Check retake policies: many colleges replace or average a failed grade if you retake the class.
Frequently asked questions
How is GPA calculated?
Each letter grade is converted to grade points (A = 4.0, B = 3.0 and so on). Multiply each class's grade points by its credit hours, add them all up, then divide by the total credit hours. Classes worth more credits count more.
What's the difference between semester and cumulative GPA?
Semester GPA only covers the classes from one term. Cumulative GPA covers every class you've taken. To update your cumulative GPA, combine your previous total grade points and credits with the new semester's.
Is an A+ worth more than 4.0?
At most US colleges an A+ counts as 4.0, the same as an A. Some schools give A+ a 4.3. This calculator uses 4.0 — check your school's policy if it differs.
What is a good GPA?
Generally, 3.0 (a B average) is considered good, 3.5 and above is very good, and 3.7+ is often required for academic honors. Competitive graduate programs and scholarships may expect 3.5 or higher, but requirements vary widely.
Does this work for weighted (honors/AP) GPA?
This calculator uses the standard unweighted 4.0 scale. For weighted GPA, many high schools add 0.5 or 1.0 for honors and AP classes — ask your school how they calculate it.
