How the cumulative GPA Calculator works
Your cumulative GPA is one big credit-weighted average, so a new semester is merged by weighting each GPA by its credits. The more credits you already have, the harder it is to move the cumulative number, in either direction.
New GPA = (current GPA × current credits + semester GPA × semester credits) ÷ total credits
Example: a 3.40 across 60 credits plus a 3.80 semester over 15 credits gives (204 + 57) ÷ 75 = 3.48.
Frequently asked questions
Why did a great semester barely move my GPA?
Leverage. With 90 credits behind you, a 15-credit semester is only 14% of the average, so even a perfect 4.0 term shifts a 3.0 cumulative to about 3.14.
Do repeated courses change this math?
At many schools a retake replaces the old grade in the GPA, which changes your current cumulative before you use this tool. Policies vary, so confirm with your registrar.
What GPA do I need to reach a target?
Work backwards: multiply your target by total future credits, subtract the points you have, and divide by remaining credits. This tool makes it fast to test scenarios.
