Weighted GPA

Pick a letter grade for at least one class.

How high school GPA is calculated

Each semester grade becomes grade points on the 4.0 scale. Multiply by the class's credits (usually 1 for a full-year class or 0.5 for a semester class), add everything up, and divide by total credits. For a weighted GPA, add the course bonus before multiplying.

Weighted GPA = Σ((grade points + level bonus) × credits) ÷ Σ(credits)

Worked example

A junior's fall semester

AP U.S. History B+ (3.3 + 1.0 = 4.3), Honors English A- (3.7 + 0.5 = 4.2), Algebra II B (3.0), Chemistry A (4.0), Spanish III A- (3.7), all 1 credit, plus PE A (4.0) at 0.5 credit.

Unweighted: (3.3 + 3.7 + 3.0 + 4.0 + 3.7 + 2.0) ÷ 5.5 = 19.7 ÷ 5.5 = 3.58.

Weighted: (4.3 + 4.2 + 3.0 + 4.0 + 3.7 + 2.0) ÷ 5.5 = 21.2 ÷ 5.5 = 3.85.

Weighted vs. unweighted: which matters for college?

Your transcript usually shows both. Admissions offices look at the unweighted GPA to compare grades fairly and at your schedule to judge rigor, so a B in AP Calculus can count for more than an A in a regular math class. Many state scholarship programs, like Florida Bright Futures and Georgia HOPE, calculate their own GPA with their own rules. Check the program's requirements.

Plan your next semester

Use the semester grade calculator to see which letter you're on track for in each class, then the raise GPA calculator to set a target. For college courses graded in credit hours, use the college GPA calculator; for 6th to 8th grade, use the middle school GPA calculator.

Frequently asked questions

What's the difference between weighted and unweighted GPA?

An unweighted GPA uses the 4.0 scale for every class. A weighted GPA adds bonus points for harder classes, usually +0.5 for Honors and +1.0 for AP, IB or dual enrollment, so it can go above 4.0 (often up to 5.0).

Which GPA do colleges look at?

Both. Colleges see the GPA on your transcript, and many recalculate their own unweighted (or partially weighted) GPA so applicants from different high schools can be compared. Course rigor is considered separately.

Is a 4.0 weighted GPA good?

It depends on your classes. A 4.0 weighted GPA could mean all A's in regular classes, or a mix of B's in AP classes. Colleges look at both the number and the difficulty of your schedule.

Do all high schools weight Honors +0.5 and AP +1.0?

That's the most common system, but not universal. Some schools weight only AP, some add +1.0 for Honors, and some don't weight at all. Your school profile or student handbook lists the rules.

Do PE, health and electives count in GPA?

Usually yes, if they're graded with letters and earn credit. Half-year or half-credit classes count at their credit value, so enter 0.5. Some schools exclude PE; check your handbook.

Does an F in an AP class get the extra point?

No. Failing grades don't earn the AP or Honors bonus at most schools, and this calculator follows that rule.

How do I convert a weighted GPA to unweighted?

Remove the bonus from each class (0.5 for Honors, 1.0 for AP/IB) and recalculate. You can't convert accurately from the final number alone, because it depends on how many weighted classes you took. Mark every class as Regular here to see your unweighted GPA.

Can I calculate my GPA without credits?

Yes. If your school counts every class the same, leave each one at 1 credit and the result is a simple average of your grade points.
