How does the GPA Calculator work out my grade point average?

For each course row, the GPA Calculator multiplies the grade's point value (A = 4.0, B = 3.0, and so on down to F = 0.0) by its credit hours, sums those quality points across all courses, and divides by your total credit hours.

What grading scale does the GPA Calculator use?

It uses the standard unweighted 4.0 scale with plus and minus grades: A+/A = 4.0, A- = 3.7, B+ = 3.3, down to D- = 0.7 and F = 0.0. This matches the scale most US colleges use.

How do I calculate a weighted GPA for honors or AP courses?

Turn on the weighted toggle, then mark each honors or AP course as weighted. The GPA Calculator adds one extra grade point to that course before averaging, the most common weighting convention.

Can I use the GPA Calculator for a cumulative GPA across multiple semesters?

Yes. Add a row for every course from every semester with its own grade and credit hours — the calculator combines all rows into one cumulative average.

Does the GPA Calculator upload my grades or transcript anywhere?

No. The GPA Calculator runs entirely in your browser. The grades and credit hours you enter never leave your device.

Why does adding a course with 0 credits not change my GPA?

The GPA Calculator ignores rows with 0 or blank credit hours since they contribute no quality points and no credit weight, so they cannot skew the average.

Common errors & troubleshooting

GPA looks lower than a school transcript shows. — Check whether your school reports a weighted GPA for honors/AP courses — turn on the weighted toggle and mark those courses to match.
A course is missing from the total. — Rows with 0 or blank credit hours are skipped on purpose so they can't drag the average down — enter the actual credit hours for that course.
Pass/Fail or Incomplete courses are throwing off the average. — Pass/Fail grades usually do not carry grade points at most schools — leave those courses out of the GPA Calculator or check your school's policy.
Cumulative GPA doesn't match a prior semester's calculator result. — Add every course from every semester as its own row with its original credit hours so the totals combine correctly into one cumulative GPA.
