- *Current GPA and semester GPA should use the same scale.
- *School grading scales, repeat-course rules, weighting, and rounding can vary.
- *Use official transcripts or school rules for final academic decisions.

How is GPA Calculated?
GPA is usually calculated by dividing total grade points by total attempted credits. Grade points are the course or semester GPA multiplied by the credit hours.
Formula used here: new cumulative GPA = ((current GPA x current credits) + (semester GPA x semester credits)) / total credits.
Weighted vs. Unweighted GPA
An unweighted GPA is usually on a 4.0 scale and treats all classes equally. A weighted GPA may use a higher scale for honors, AP, IB, or similar courses. This calculator can estimate either one, but the current GPA and semester GPA must use the same scale.
Example Scenario
If you have a 3.2 GPA with 45 credits and earn a 3.8 GPA in 15 credits this semester:
- Total Points:(3.2 x 45) + (3.8 x 15) = 201
- Total Credits:45 + 15 = 60
- New Cumulative GPA:201 / 60 = 3.35
Common mistakes
- Mixing a 4.0 semester GPA with a 5.0 weighted cumulative GPA.
- Forgetting that higher-credit courses affect GPA more than lower-credit courses.
- Ignoring school rules for repeated classes, pass/fail courses, or withdrawals.
- Using this estimate instead of official transcript rules for scholarships or applications.

Frequently Asked Questions
Common questions about GPA Calculator and how to read the result.
Does this work for high school and college?
Yes! The math for GPA is the same for both. Just make sure you use the correct credit values (hours or units).
What if I'm retaking a class?
If your school replaces grades, you should subtract the old credits and points before using this calculator for a more accurate result.
Can I use this for a 5.0 scale?
Yes. The calculator is scale-agnostic. As long as your inputs follow the same scale, the output will be correct.
How accurate is this for my specific school?
While this uses the standard GPA formula, some schools have unique weighting or rounding rules. Check your student handbook for exact details.
What are grade points?
Grade points are GPA value multiplied by credits. A 3.8 GPA over 15 credits contributes 57 grade points.
Does credit weight matter?
Yes. Courses or semesters with more credits have more effect on cumulative GPA.
