GPA Calculator
Calculate semester GPA, cumulative GPA, or project your future GPA with the What-If tool.
The GPA calculator converts letter grades and credit hours into a semester GPA, cumulative GPA, or projected future GPA. It supports both the standard 4.0 scale and the 4.3 scale used by some universities that award A+ grades. The What-If GPA tool lets students model how planned courses will affect their overall academic standing before registering.

Frequently Asked Questions
How is GPA calculated?
GPA is calculated by multiplying each course grade (on a 4.0 scale) by its credit hours, summing all those grade points, then dividing by total credit hours. For example: an A (4.0) in a 3-credit course earns 12 grade points.
What is the difference between semester GPA and cumulative GPA?
Semester GPA covers only the courses taken in a single term. Cumulative GPA averages all your coursework across every semester, weighted by credit hours completed.
What GPA do I need for the Dean's List?
Most universities require a 3.5 or higher GPA for the Dean's List, though requirements vary by institution. Some schools require a 3.7 or a 4.0.
What is a 4.3 GPA scale?
Some high schools and colleges use a 4.3 scale where an A+ is worth 4.3 instead of 4.0. This allows top students to exceed a 4.0 GPA. The rest of the scale (A = 4.0, B+ = 3.3, etc.) remains the same.
How do I use the What-If GPA calculator?
Enter your current cumulative GPA and total credits earned, then add the courses you plan to take with your expected grades. The calculator shows your projected new cumulative GPA immediately.
