Weighted GPA Calculator

About the Weighted GPA Calculator

Many American high schools report two grade point averages. The unweighted GPA uses the standard 4.0 scale, where an A is worth 4.0 whatever class it comes from. The weighted GPA rewards harder classes by adding a bonus to honors, Advanced Placement (AP), International Baccalaureate (IB) and dual-enrollment courses, so an A in AP Calculus can be worth 5.0. The weighted figure lets students who take demanding schedules show it in their GPA.

This weighted GPA calculator works out both figures from a simple list of your courses. For each course, enter a name, the credits, the letter grade and, if it applies, a tag: H for honors, or AP, IB or DE for college-level classes. The default bonuses are half a point for honors and a full point for college-level classes, and you can change them to match your school's policy.

How to Use the Weighted GPA Calculator

Enter one course per line: a name, the credits, the letter grade, then an optional H, AP, IB or DE tag — for example, Calculus 1 B+ AP.

Set the honors bonus and the AP, IB and dual-enrollment bonus used by your school.

The calculator shows the weighted GPA, the unweighted GPA and the points for each course.

The Formula

  weighted points    = grade points + bonus (none for an F)
  weighted GPA       = Σ (credits × weighted points) ÷ Σ credits
  unweighted GPA     = Σ (credits × grade points) ÷ Σ credits

  grade points: 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 · D- 0.7 · F 0

Step-by-Step Example

Four one-credit courses:

  English    A             4.0
  Calculus   B+ AP   3.3 + 1.0 = 4.3
  History    A- H    3.7 + 0.5 = 4.2
  Biology    B             3.0

  weighted    (4.0 + 4.3 + 4.2 + 3.0) ÷ 4 = 15.5 ÷ 4 = 3.875 → 3.88
  unweighted  (4.0 + 3.3 + 3.7 + 3.0) ÷ 4 = 14.0 ÷ 4 = 3.50

The two bonuses add 1.5 points across four credits, raising the GPA by 0.38.

Two AP classes with A grades each earn 4.0 + 1.0 = 5.0, a weighted GPA of 5.00.

Weighted Versus Unweighted GPA

The unweighted GPA answers one question: how high were your grades? The weighted GPA answers a second: how high were your grades given how hard your classes were? A student with straight A grades in standard classes has a 4.0 on both scales. A student with a mix of A and B grades in AP classes might have a 3.6 unweighted but a 4.4 weighted. Neither figure is better; they measure different things. That is why transcripts often show both, and why admissions officers look at the courses themselves as well as the numbers.

How Schools Weight Classes

There is no national standard. The most common approach adds 0.5 for honors and 1.0 for AP, IB and dual-enrollment classes, creating a 5.0 scale. Some schools add 1.0 for honors as well, some add only 0.5 for everything, and some cap the number of weighted classes that count or weight only classes taken in the final years. A few schools weight grades only down to C, so a D in an AP class earns no bonus. Almost all give no bonus to an F. Enter your school's own values in the bonus boxes, and check its handbook or ask a counselor when unsure.

How Colleges Use Weighted GPAs

Because schools weight so differently, many colleges recalculate every applicant's GPA on a common basis. Some use the unweighted grades from core academic subjects — English, maths, science, social studies and languages — and ignore physical education and electives. Others add their own bonus for a limited number of honors and AP classes. The University of California, for example, adds a point for up to eight approved honors-level semesters. Alongside the GPA, admissions readers consider the rigor of your schedule compared with what your school offers, so a challenging programme counts even where the bonus does not.

Choosing Harder Classes

A weighted GPA can tempt students to take as many AP classes as possible, but a heavy load that leads to lower grades, less sleep and little time for other interests may not help. A B in an AP class is worth 4.0 weighted, the same as an A in a standard class, but an unweighted recalculation would treat it as a 3.0. The best strategy is usually to take the most demanding schedule in which you can still earn strong grades, focusing on subjects related to what you want to study.

Semester and Full-Year Courses

High schools usually award credit by semester, so a full-year AP course often appears on the transcript as two separate grades, each worth half a credit or one semester credit. Enter each semester as its own line so that each grade counts correctly. A course taken for one semester counts once. If your school uses credit values such as 0.5 or 1.0, enter them exactly as shown on your transcript; the calculator weights each course by its credits, so longer courses carry more influence on both GPAs.

Understanding Your Result

The headline is your weighted GPA to two decimal places.

The unweighted line gives the GPA on the plain 4.0 scale and how much the bonuses add.

The by course line shows each course's grade, tag and weighted points.

The worth knowing line reminds you that colleges often recalculate GPAs.

When Should You Use This Calculator?

Use it to check the weighted GPA your school reports on your transcript.

Use it to see how adding an honors or AP class might change your GPA.

Use it to compare your weighted and unweighted GPAs before college applications.

Common Mistakes

Adding the bonus to failing grades. Most schools give no bonus to an F.

Using another school's bonus values. Weighting policies vary widely.

Reporting a weighted GPA as unweighted. Applications usually ask which one they want.

Forgetting semester credits. A full-year class may count as two semester credits.
