GPA calculator, both numbers at once
GPA is weighted by credits, not by how many courses you took. Convert each letter grade to points on the 4.0 scale, multiply by the credits for that course, add them, and divide by total credits. Weighted GPA adds a point for AP and honours courses, which is how it exceeds 4.0.
Most calculators give you one number and leave you guessing which one your school uses. This shows the unweighted and the weighted GPA side by side, so you can see what the AP and honours courses are actually doing for you.

Calculate both
A letter grade and the credits for each course. Tick the box for AP and honours courses.
This uses the common 4.0 scale, with a full extra point for AP and honours courses. Schools differ: some ignore plus and minus, some weight honours by half a point, some do not weight at all. Your transcript is the number that counts, and this is the estimate.
What the two numbers mean
Unweighted caps every course at 4.0, so an A in an easy class and an A in an AP class count the same. Weighted adds a point for harder courses, which is why weighted GPAs above 4.0 exist. Colleges usually recalculate to their own scale anyway, so knowing both is more useful than picking one.
Why credits matter more than course count
GPA is weighted by credits, not by how many courses you took. A poor grade in a three-credit course pulls harder than the same grade in a one-credit elective, which is often why a GPA does not move the way a student expects after a good term.
Where schools differ
This uses the most common convention: the 4.0 scale, plus and minus counted, and a full extra point for AP and honours. Your school may ignore plus and minus, weight honours by half a point rather than a full one, or not weight at all. Your transcript is the number that counts; this is the estimate you use to plan.
Watching it without typing it
Typing grades in works once. If you want the number to stay current, SchoolOps reads your courses and grades from the platform your school posts them on, keeps the GPA up to date, and lets you set a target on a course to see what it would do. That part is free with an account.
Questions
How do I calculate my GPA?
Convert each letter grade to points on the 4.0 scale, multiply by the credits for that course, add those together, and divide by total credits. The calculator above does it, including the weighted version.
What is a weighted GPA?
A scale that gives extra points for harder courses, usually a full point for AP and honours, which is how a weighted GPA can exceed 4.0. Unweighted caps every course at 4.0 regardless of difficulty.
Does a plus or minus change my GPA?
At most schools yes: an A- is 3.7 and a B+ is 3.3 rather than a flat 4.0 and 3.0. Some schools ignore them entirely, so check how yours reports it before planning around a decimal.
Why is my school GPA different from this?
Scales vary. Schools differ on whether plus and minus count, how much AP and honours are worth, and which courses are included at all. Treat this as a planning estimate and your transcript as the record.
