About this calculator
The GPA Calculator computes the weighted grade point average on the American 4.0 scale. GPA is obtained by dividing the sum of grade points multiplied by credits for each course by the total credits. For example, an A (4.0) in a 3-credit course contributes 12 points; a B (3.0) in 2 credits contributes 6 points. The final GPA is the sum of these products divided by total credits.
This tool is useful for Brazilian students aiming to study in the United States or at institutions using the American system. It is also used by candidates for exchange programs, scholarships, or programs requiring GPA conversion. By entering grades and credits for each course, the user gets the exact GPA.
Cautions: the grade scale may vary (A+ = 4.0, A = 4.0, A- = 3.7, etc.). Check your institution's conversion table. Also, the calculation only considers courses with credits; non-credit courses should not be included. The result is a weighted average reflecting overall academic performance.
Frequently asked questions
What does a 4.0 GPA mean?
A 4.0 GPA is the highest possible on the American scale, equivalent to earning A (or A+) in all courses. It represents excellent performance.
How do I convert Brazilian grades to GPA?
Use your institution's table or common standards: 9-10 becomes A (4.0), 8-9 becomes B (3.0), 7-8 becomes C (2.0), below 7 becomes D or F (1.0 or 0). Check the target program's guidelines.
Can I include courses without credits?
No. Courses without credits should not be entered because they do not weight the average. Only include those with a defined credit load.
Is the calculated GPA final for my application?
It may be, but each university may recalculate using its own method. Use this result as a reference, but always check official requirements.
What if I have grades like A- or B+?
Enter the corresponding numeric value (A- = 3.7, B+ = 3.3). The calculator accepts decimal values. Verify the exact scale used by your institution.
