The chart appears with your result

A high school GPA is the credit-weighted average of grade points: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. A weighted GPA adds 0.5 for honors and 1.0 for AP or IB classes. An A in AP Calculus and a B in Honors Chemistry give 3.50 unweighted and 4.25 weighted.

About this tool

Students filling in college applications, scholarship forms or a counselor meeting often need two numbers: the plain 4.0-scale GPA and the weighted one that rewards harder classes. Enter each class on its own row with the letter grade from your report card, whether it was regular, honors or AP/IB, and its credit value (1 for a full-year class, 0.5 for a semester). The calculator shows both GPAs, the total credits, a table of points per class and a bar chart comparing the weighted points of each course. One limit: schools set their own weighting, and some cap the bonus, use a 5.0 or 100-point scale, or leave out electives, so the figure on your official transcript can differ.

How to use it

Add one row per class
Type the course name if you like, then use Add course for every class you want counted.
Pick the grade and level
Choose the letter grade and whether the class was regular, honors or AP/IB.
Set the credits
Use 1 for a full-year class and 0.5 for a one-semester class, or the credit value your school prints.
Read both GPAs
The headline is the unweighted GPA; the weighted GPA, credits and per-class table sit below it.

Examples

One A and one B

Your courses: English 10 × A × regular × 1; Biology × B × regular × 1

Result Unweighted GPA (4.0 scale): 3.50
Weighted GPA: 3.5
Total credits: 2
Courses counted: 2
Unweighted quality points: 7

Unweighted quality points = Σ(grade points × credits) = 7
Unweighted GPA = 7 ÷ 2 credits = 3.5
Weighted quality points (honors +0.5, AP/IB +1.0) = 7
Weighted GPA = 7 ÷ 2 = 3.5

Two full-credit regular classes with an A and a B average to a 3.50 unweighted, and the weighted figure is the same because neither class carries a bonus.

An AP A and an honors B

Your courses: AP Calculus AB × A × ap × 1; Honors Chemistry × B × honors × 1

Result Unweighted GPA (4.0 scale): 3.50
Weighted GPA: 4.25
Total credits: 2
Courses counted: 2
Unweighted quality points: 7

Unweighted quality points = Σ(grade points × credits) = 7
Unweighted GPA = 7 ÷ 2 credits = 3.5
Weighted quality points (honors +0.5, AP/IB +1.0) = 8.5
Weighted GPA = 8.5 ÷ 2 = 4.25

The A in AP counts 5.0 and the honors B counts 3.5 on the weighted scale, so the weighted GPA is 4.25 while the unweighted stays at 3.50.

A semester elective at half credit

Your courses: US History × A × regular × 1; Health × C × regular × 0.5

Result Unweighted GPA (4.0 scale): 3.33
Weighted GPA: 3.33
Total credits: 1.5
Courses counted: 2
Unweighted quality points: 5

Unweighted quality points = Σ(grade points × credits) = 5
Unweighted GPA = 5 ÷ 1.5 credits = 3.33
Weighted quality points (honors +0.5, AP/IB +1.0) = 5
Weighted GPA = 5 ÷ 1.5 = 3.33

A C in a half-credit class pulls the average down only half as much as a full-credit C would: (4 + 1) ÷ 1.5 = 3.33.

How it is calculated

GPA = Σ(points × credits) ÷ Σ credits; weighted points = points + bonus

points: grade points on the 4.0 scale: A+ and A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3, C 2.0, C- 1.7, D+ 1.3, D 1.0, F 0
credits: credit value of the class, usually 1 per year or 0.5 per semester
bonus: 0 for regular, 0.5 for honors, 1.0 for AP or IB; never applied to an F

Each class contributes quality points equal to its grade points times its credits. Dividing the total by the credits gives the unweighted GPA, so a half-credit class counts half as much as a full-year one. The weighted GPA repeats the sum after adding the level bonus to every passing grade, which is the most common convention among US high schools.

When not to use it

If your school publishes its own weighting table, its transcript GPA is the one colleges see.
Grades on a 100-point or 5.0 scale need converting to letters first.

Common mistakes

Entering a semester class as one full credit, which doubles its weight.
Marking dual-enrollment or pre-AP classes as AP when the school weights them as honors or not at all.
Comparing a weighted GPA from one school with an unweighted GPA from another.

Frequently asked questions

Do colleges look at weighted or unweighted GPA?

Both appear in admissions. Many colleges recalculate an unweighted GPA from core academic classes so applicants from different schools can be compared, then read the transcript to see how many honors and AP classes you took.

Is an A+ worth more than 4.0?

On the common College Board 4.0 conversion, an A+ is 4.0, the same as an A. A few schools award 4.3 for an A+; if yours does, your transcript GPA will be slightly higher than this result.

Why does an F get no AP bonus here?

Most schools add the honors or AP bonus only to passing grades, so a failed AP class counts 0 points either way. It still adds its credits, which lowers both averages.

Can my weighted GPA go above 4.0?

Yes. With AP or IB classes weighted by an extra point, straight A grades in those classes count 5.0 each, so a schedule heavy in advanced classes can produce a weighted GPA between 4.0 and 5.0.

Which classes should I include?

For a cumulative figure, include every graded class on your transcript from grade 9 onward. For a core academic GPA, keep only English, math, science, social studies and world language, which is what many admissions offices use.

How many credits is a semester class?

Most US high schools give 0.5 credit for a one-semester class and 1.0 for a full-year class. Block schedules and some states use different values, so check the credit column on your report card.
