GPA Calculator
Your grade point average on the 4.0 scale, weighted by credit hours.
Good to know. A 4-credit B pulls a GPA down more than a 1-credit C. Credit hours are the weights.
How it works
In plain words
Each letter grade becomes grade points (A = 4.0, B = 3.0 and so on, with + and − in between). Multiply each by the course’s credit hours, add them up, and divide by the total credit hours.
The formula
GPA = Σ(grade points × credits) ÷ Σ credits 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 · F 0
Worked example
A (4.0 × 3) + B+ (3.3 × 4) + A− (3.7 × 3) + C (2.0 × 2) = 12 + 13.2 + 11.1 + 4 = 40.3 grade points over 12 credits, a GPA of 3.36.

About the GPA calculator
Grade point average is how US high schools and colleges summarise grades in one number. Each letter grade is worth a number of points on a 4.0 scale, and courses with more credit hours count for more. A 4-credit course affects your GPA twice as much as a 2-credit one.
Enter one course per line: the letter grade, a space, and the credit hours. Plus and minus grades use the common scale: A− is 3.7, B+ is 3.3, B− is 2.7 and so on. An A+ counts as 4.0 at most schools. If your school uses different values, enter grade points instead of letters, for example 3.67 instead of A−.
For a cumulative GPA, enter every course you have taken, or add your previous total as one line: a 3.4 GPA over 60 credits can be entered as “3.4 60”. Then add this semester’s courses below it to see where your overall GPA will land.
This is an unweighted GPA. Many high schools add a point for honors, AP or IB classes (a weighted GPA, out of 5.0); enter those courses with the extra point, such as 5 for an A in an AP class. Pass/fail courses usually don’t count toward GPA, so leave them out.
Questions people ask
How do I calculate my GPA?
Multiply each course’s grade points by its credit hours, add them up, and divide by your total credit hours.
What is an A− worth?
3.7 on the common 4.0 scale. B+ is 3.3 and B− is 2.7.
How do I calculate a cumulative GPA?
Enter your previous GPA and total credits as one line, like “3.4 60”, then add the new courses.
Is a 3.5 GPA good?
It is a B+ to A− average, above the typical college GPA of about 3.1 to 3.2.
