How This Calculator Works
Use this gpa tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.
Use the GPA calculator to estimate how a new course grade may affect your cumulative GPA based on credits.
The calculator uses a credit-weighted average of current GPA and the new course grade points.
Formula
Updated GPA = (current GPA × current credits + course grade × course credits) / total credits.
Example Calculation
A 3.25 GPA over 45 credits plus a 3.7 grade over 3 credits estimates a 3.28 updated GPA.
