GPA Calculator
Calculate GPA using course grades and credit hours on a 4.0 scale.
GPA
| Course | Grade points | Credits | Quality points |

How we calculated it
About the GPA Calculator
A GPA is not a simple average of course grades when classes carry different credit hours. This calculator converts each grade into quality points and combines them according to the credits that actually count.
Schools do not all use the same grade-point scale. Repeated courses, pass/fail classes, weighted high-school courses and transfer credits can also be treated differently, so use the institution’s official rules when the GPA matters formally.
How to Use the GPA Calculator
- Enter each course grade or grade-point value using the scale your institution uses.
- Enter the credit hours for each course. Do not give every course the same weight unless the credits are actually equal.
- Exclude courses that the institution does not count toward GPA, such as some pass/fail classes.
- Calculate the weighted GPA and compare it with the official transcript rules before using it for eligibility decisions.
How the Calculation Works
Quality points for each course = grade-point value × course credits. Total quality points are the sum across all included courses.
GPA = total quality points ÷ total GPA credits. A cumulative calculation can combine previous quality points and credits with the new term before dividing.
Worked example
GPA Calculator Worked Example
Three courses with different credits
Suppose A (4.0) in a 3-credit course gives 12 quality points, B (3.0) in a 4-credit course gives 12 points and A- (3.7) in a 2-credit course gives 7.4 points. Total = 31.4 quality points over 9 credits. GPA = 31.4 ÷ 9 ≈ 3.49.
Result guide
Understanding Your GPA Calculator Result
The GPA is a credit-weighted average, not a simple average of letter grades. A grade in a 4-credit course has twice the effect of the same grade in a 2-credit course.
Before you rely on the answer
Assumptions and Limitations
- Grade-point values match the institution’s scale.
- Only GPA-bearing credits are included.
- Repeated-course replacement, transfer-credit and rounding policies are excluded unless explicitly modeled.
Practical tip
Using This Result in Practice
If you are planning a target GPA, work with quality points rather than trying to average old and new GPA values directly. The number of credits behind each GPA matters.

For a single course with weighted assignments or exams, use the Grade Calculator instead of GPA.
Common questions
GPA Calculator FAQ
Why can’t I just average my course GPAs?
Courses may carry different credits, so GPA must weight each grade by its credit hours.
Do pass/fail courses affect GPA?
Often they do not, but policies vary. Include only courses the institution counts in its GPA calculation.
How do repeated courses affect cumulative GPA?
Some institutions replace the old grade, some count both attempts and some use another rule. Follow the official academic policy.
