About this calculator
It matters when grades, percentages or averages decide a next step and hand arithmetic is error-prone. The governing relationship: GPA Calculator converts each course grade to grade points, weights by credit hours, and averages to a GPA. See it on real numbers: For grades A (4.0, 3 cr) and B (3.0, 3 cr): GPA = (4.0×3 + 3.0×3) ÷ 6 = 3.5 . The calculator above applies the same steps to whatever you enter — computed locally, nothing sent anywhere.
How to use
- List each course on its own line as grade, credits.
- Use a letter grade (A, B+, C ...) or a numeric grade point.
- Add the credits each course carries.
- Tap Calculate to see your credit-weighted GPA.

FAQ
Which grade scale is used for letters?
Letter grades use a 4.0 scale (A=4.0, A-=3.7, B+=3.3, B=3.0, and so on). If you enter numeric grade points instead, they are used exactly as typed.
Does the GPA Calculator send my data to a server?
No. The GPA Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Can I mix letters and numbers?
Yes. Each line can be a letter grade or a numeric grade point, paired with credits; the tool maps letters and keeps numbers as given.
Is the GPA weighted by credits?
Yes. Each course's grade points are multiplied by its credits and divided by total credits, so heavier courses influence the GPA more.
