GPA Calculator
Grade Point Average (4.0 scale)
This free GPA Calculator works out your Grade Point Average on the standard 4.0 scale from the grades and credit hours of each course. Add a row for every class, choose its letter grade, enter its credits, and the calculator multiplies each grade's points by its credits, totals everything, and divides by the total credits — the weighted method universities actually use, so a four-credit course rightly counts for more than a one-credit seminar. Course names are optional and exist only to help you keep track of your own rows.
The scale used is the common unweighted one: A and A plus both score 4.0, A minus 3.7, B plus 3.3, and so on down to F at 0.0. Schools differ — some award 4.3 for an A plus, some use weighted GPAs that add points for honours or advanced classes — so treat this result as the standard benchmark and check your own institution's rules for official figures. Rows can be removed individually, and blank courses with zero credits are simply ignored rather than dragging the average down. The whole calculation happens in your browser, and your grades are never uploaded or stored anywhere.
How to use
- Use one row per course, naming it if that helps you.
- Select the letter grade you earned in that course.
- Enter the course's credit hours in the credits box.
- Add or remove rows until every course is listed once.
- Click Calculate GPA to see your average and total credits.
Frequently asked questions
Why do credits change the result so much?
GPA is a weighted average, and credits are the weights. An A in a four-credit course contributes four times as much as an A in a one-credit course. This is why a single poor grade in a heavy course can move a GPA noticeably, while a light course barely shifts it.
Is an A plus worth more than an A?
On the scale used here, no: both are capped at 4.0, which is the most common convention. Some schools use a 4.3 or 5.0 scale where an A plus earns extra. If your school does that, your official GPA may be slightly higher than the figure shown here.
Does an F really hurt that much?
Yes. An F earns zero points but its credits still count in the divisor, so it pulls the average down exactly as much as an A pulls it up for the same credits. Retaking the course helps only if your school replaces the grade, which many do and some do not.
How can I estimate my GPA after next semester?
Add your completed courses plus the courses you are taking, entering the grades you realistically expect. Try a hopeful and a cautious set of grades to see the range of possible outcomes, which is a practical way to set targets.
