About the GPA Calculator
GPA is a weighted average, not a simple average of letter grades — a 4-credit course affects your overall GPA more than a 1-credit course. Students often calculate this by hand incorrectly by simply averaging grade points without weighting by credits.
This calculator multiplies each course's grade points by its credit hours, sums those totals, and divides by total credits attempted, matching the standard method most US colleges and universities use for cumulative GPA.
Frequently Asked Questions
Does every school use the same 4.0 scale?
Most US institutions use a 4.0 scale, but grading scale details (whether A+ counts as 4.0 or 4.3, how +/- grades are weighted) vary by school — always confirm against your institution's official policy for your transcript.
What's the difference between GPA and weighted/honors GPA?
A weighted GPA gives extra grade-point value to honors, AP, or IB courses (sometimes up to 5.0), while an unweighted GPA treats all courses equally on a standard 4.0 scale.
How do I calculate my cumulative GPA across multiple semesters?
Add every course from every semester into this calculator together — cumulative GPA is calculated the same way as a single semester, just across your entire course history.
