GPA CALCULATOR
GPA Calculator (Weighted and Unweighted)
Enter each course's grade and level to get an unweighted and a weighted GPA on a 4.0 scale. The bonus rules are published below. Your school's or a university's own method may differ.
Everything you type is calculated in your browser only. Nothing is sent or stored, and no email address or contact details are needed.

How it works and what it assumes
Petra converts each letter grade (A+ to F) to grade points on a 4.0 scale and takes a credit-weighted average, the common approach. Unweighted GPA averages only those grade points. Weighted GPA adds a bonus by course level to each passing course (D- or above) before averaging. Courses graded F get no bonus.
How much extra weight a course earns differs by school and there is no single official method. The table below shows Petra's assumptions. For example, some schools weight IB SL and some do not, and AP or IB HL may earn 1.0 at one school and 0.5 at another. If your transcript states its own method, use the school's figure.
| Grade | Grade points |
|---|---|
| A+ | 4.0 |
| 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 |
| Course level | Bonus |
|---|---|
| Regular | +0.0 |
| Honors | +0.5 |
| AP | +1.0 |
| IB HL | +1.0 |
| IB SL | +0.5 |
| College-level / Dual Enrollment | +1.0 |
Reading your result
Unweighted GPA compares grades without regard to how hard the courses were. Weighted GPA tries to reflect that you took harder courses, and it can go above 4.0.
Universities sometimes use the GPA printed on your transcript as is and sometimes recalculate it themselves. Which they do varies by university, so treat this number as a way to see roughly where you stand.
What this tool cannot tell you
- School-specific scales (for example A+ = 4.3, or converting from percentages) are not reflected.
- Converting Japanese school ratings (the 5-point scale) or percentage grades is outside this tool.
- Recalculation by a university at application time, GPA limited to certain subjects, and definitions of academic GPA are not reflected.
- This result does not indicate admission or scholarship outcomes.

Frequently asked questions
Questions we are often asked about reading the result.
Should I use weighted or unweighted GPA?
It depends on what the recipient asks for. If an application or university guide says "unweighted" or "weighted", follow it. If it does not say, check the value printed on your school transcript.
Why is my transcript GPA different from this result?
Schools differ in their conversion tables, the size of the bonus, which courses count and how credits are treated. This tool uses Petra's stated assumptions and is not your school's official figure.
What should I enter for credits?
A full-year course is commonly 1 and a semester course 0.5, but schools differ. Use the credit value on your transcript if there is one; otherwise leaving every course at 1 is fine.
Can I use Japanese 5-point school ratings?
This tool takes letter grades (A+ to F). There is no official conversion from Japanese ratings and it differs by school and applicant destination, so it is not covered here.
