What is the difference between weighted and unweighted GPA?

An unweighted GPA treats every course equally on a 4.0 scale, so an A in an AP class and an A in a standard class both count as 4.0. A weighted GPA adds bonus points for more rigorous courses — typically 0.5 for Honors and 1.0 for AP — raising the maximum possible GPA to 4.5 or 5.0.

How is GPA calculated?

Each course earns quality points equal to its grade points multiplied by its credit hours. GPA is the sum of all quality points divided by the total credit hours. For example, an A (4.0) in a 3-credit course contributes 12 quality points.

What grade point value does each letter grade have?

A+/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 = 0.0.

Summary

This GPA calculator computes your grade point average on a 4.0 scale from the courses you enter. Add each course with its letter grade (A+ through F) and credit hours, and it converts every grade to grade points, weights them by credit hours, and divides by total credits. Switch on weighting to add the standard Honors (+0.5) and AP (+1.0) bonuses used by many high schools and colleges.

How it works

Select your grading scale: 4.0 (unweighted), 4.5 (Honors weighted), or 5.0 (AP weighted) using the scale selector at the top of the input panel.
For each course, enter the course name, choose the letter grade from the dropdown, enter the credit hours, and select the course type (Regular, Honors, or AP).
Click "Add Course" to insert additional rows if you have more than five courses.
Click "Calculate GPA" to compute your GPA. The result panel shows your GPA, total credits, and a quality points table.
Click "Save as PDF / Print" to open the browser print dialog. Choose "Save as PDF" in your printer options to download a copy.

Use cases

High school students can calculate their weighted GPA for college applications by marking AP and Honors courses and selecting the 5.0 or 4.5 scale.
College students can track their semester GPA by entering each enrolled course's grade and credit hours after grades are posted.
Academic advisors can quickly demonstrate to a student how a single course grade will impact their cumulative GPA.
