How to Use the GPA Calculator

1. Pick your scale: Unweighted 4.0 if every course counts the same, or Weighted if honors and AP courses earn bonus points at your school.
2. For each course, choose the letter grade you earned and enter the credit hours it is worth. High school courses are usually 0.5 or 1 credit; college courses are usually 3 or 4.
3. Use Add course for more classes, or the remove button to delete a row.
4. Read your GPA at the bottom of the form. It recalculates on every keystroke, and Copy puts the number on your clipboard.

How It's Calculated

GPA is a credit-weighted average of your grade points. Longer courses count more, which is why a 4-credit class moves your GPA more than a 1-credit one.

Each course's grade points multiplied by its credits gives its quality points. Add the quality points for every course, then divide by the total credits attempted.

Worked example: an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course gives (4.0 × 3) + (3.0 × 4) = 24 quality points across 7 credits, so 24 ÷ 7 = 3.43.

Weighting: in weighted mode a bonus is added to the grade points before multiplying — 0.5 for honors and 1.0 for AP, IB or dual enrollment. So an A in an AP course is worth 5.0. The bonus is not applied to an F, which stays at 0.0. Every school sets its own weighting rules, so confirm yours before relying on the weighted number.

An F counts as 0 grade points but its credits still count in the denominator, which is why failing a course pulls a GPA down twice.

Frequently Asked Questions

How is GPA calculated?

Each letter grade converts to grade points on the 4.0 scale. Multiply each course's grade points by its credit hours to get quality points, add all the quality points together, then divide by the total credit hours attempted.

What's the difference between weighted and unweighted GPA?

An unweighted GPA treats every course the same and tops out at 4.0. A weighted GPA adds bonus points for harder courses — most commonly 0.5 for honors and 1.0 for AP, IB or dual enrollment — so an A in an AP class can be worth 5.0. Weighting policies are set by each school, so check your handbook or transcript legend.

Is an A+ worth 4.0 or 4.3?

Most US schools cap the unweighted scale at 4.0 and give an A+ the same 4.0 as an A. A minority of colleges use 4.3 for an A+. This calculator uses 4.0 because it is the more common standard.

How do I calculate my cumulative GPA across semesters?

Multiply your existing cumulative GPA by the credits you have already completed — that gives your prior quality points. Add this semester's quality points and credits to those totals, then divide the combined quality points by the combined credits. Pass/fail courses usually earn credit without grade points, so leave them out of both totals.
