How is GPA calculated?

Each grade becomes a point value (A = 4.0, B = 3.0, and so on), which is multiplied by the course's credit hours to give quality points. Add up all the quality points and divide by the total credit hours. A 4-credit A and a 1-credit C average to 3.6, not 3.0 — the bigger class pulls harder.

What is the difference between weighted and unweighted GPA?

Unweighted GPA caps every course at 4.0 regardless of difficulty. Weighted GPA adds a bonus for harder classes — typically +0.5 for honors and +1.0 for AP or IB — so a straight-A student taking AP courses can land above 4.0. High schools report weighted figures; many college admissions offices recalculate an unweighted GPA to compare applicants fairly.

Can I enter percentages instead of letter grades?

Yes. Type 92 or 92% and it maps to A- on the standard US scale (93+ is an A, 90–92 an A-). You can also type a grade point directly, like 3.7.

Does an A+ count as more than 4.0?

It depends on the school. Most US institutions cap A+ at 4.0; some award 4.3. Use the scale dropdown to pick the one your school uses.

Are my grades stored anywhere?

No. The calculation runs in JavaScript in your browser. Nothing is uploaded, saved, or logged, and closing the tab discards everything you typed.

Enter each course with its grade and credit hours to get your grade point average on the 4.0 scale. Letter grades, percentages, and raw grade points all work, and marking a class as Honors or AP adds the usual weighted bonus. Add a prior GPA at the bottom to roll this term into your cumulative average.

How it works

1
Add your courses Type a course name, its grade, and how many credit hours it carries. Grades can be letters (A-, B+), percentages (92%), or grade points (3.7) — the calculator works out which you meant.
2
Mark honors and AP classes Set the level dropdown to Honors for a +0.5 bonus or AP/IB for +1.0. Both the weighted and unweighted GPA are shown, since colleges often recalculate the unweighted figure themselves.
3
Roll in your cumulative GPA Enter your GPA and total credits from previous terms in the bottom panel to see the new cumulative average after this term's grades are added.
