Semester GPA Calculator
Calculate your semester GPA from letter grades and credit hours on the 4.0 scale, and see your new cumulative GPA after this term.
Your semester or term GPA is the credit-weighted average of the grade points you earned in that term. Enter each course’s letter grade and credit hours to get the GPA and the quality points behind it. Add your cumulative GPA and credits from earlier terms to see where your overall GPA stands after this semester.
How to use this tool
- Pick the letter grade for each course you took this term, leaving unused rows on “—”.
- Enter each course’s credit hours.
- Choose whether your school counts an A+ as 4.0 or 4.3.
- Optionally enter your cumulative GPA and graded credits before this term.
Formula
GPA = Σ(grade points × credit hours) ÷ Σ credit hours
Grade points on the standard US scale: 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. Pass/fail courses earn credit but are left out of the average. New cumulative GPA = (previous GPA × previous credits + this term’s quality points) ÷ (previous credits + this term’s credits).
Example
An A in a 3-credit course, a B in a 4-credit course, an A− in a 3-credit course and a C+ in a 2-credit course give 12 + 12 + 11.1 + 4.6 = 39.7 quality points over 12 credits, a 3.31 semester GPA. With a 3.50 GPA over 30 earlier credits, the cumulative GPA becomes 144.7 ÷ 42 = 3.45.
Frequently asked questions
Why do credit hours matter?
Each grade is weighted by its credits, so a B in a 4-credit course pulls your GPA down more than a B in a 1-credit lab.
Is an A+ worth more than 4.0?
At most US colleges an A+ is capped at 4.0, but some award 4.3. Check your registrar’s grading policy and set the scale to match.
Do W, I or pass/fail grades count?
At most schools a W carries no grade points and does not affect GPA, an incomplete is left out until a final grade is posted, and pass/fail credits count toward graduation but not the GPA.
What happens when I retake a course?
Policies differ: many schools replace the earlier grade, others average both attempts. Follow your school’s rule when entering previous GPA and credits.
