🎓 GPA Calculator
Calculate weighted GPA from course rows, credits, letter grades, and an optional custom grade scale.
One course per line: name, credits, grade.
GPA checks
Validates course row shape, positive credits, known grades, custom scale JSON, and weighted scale assumptions. Official GPA depends on your school’s repeat, withdrawal, pass/fail, and weighting rules.
Why it is useful
It helps students plan semester outcomes, required grades, and academic scenarios before official transcripts update.
How it works
The browser multiplies grade points by credits, sums them, and divides by total attempted credits.
Best input
Use your school’s exact grade scale, credits, and repeat-course policy.
Planning tip
Run best-case and conservative scenarios when planning target grades.
Privacy note
Grade calculations happen locally in your browser.
Important limitation
Schools use different grade scales, weighting, pass/fail rules, withdrawals, and repeat policies. Official GPA comes from the institution.
