How GPA is calculated
A grade point average weights each course grade by its credit hours. You multiply each course's grade points by its credits, add those together, and divide by the total credits taken. A heavier course therefore moves your GPA more than a lighter one.
Some schools use a weighted GPA that gives extra points for advanced or honours classes, while an unweighted GPA treats every course on the same scale. Knowing which your institution uses helps you read the number correctly.
Understanding and improving your GPA
Because credits are part of the formula, doing well in high-credit courses lifts your GPA more, and a single low grade in a big course weighs heavily. Retake policies, where allowed, can replace or average out a poor grade.
It also helps to separate your semester GPA from your cumulative GPA: one strong term can nudge the cumulative figure, but the more credits you have already earned, the harder it is to move. Plan improvements with that in mind.
Frequently Asked Questions
How is GPA calculated?
Each grade is converted to grade points (A = 4.0, B = 3.0, and so on), multiplied by the course's credit hours, summed, and divided by total credit hours to give a weighted average.
Which grading scale does it use?
It uses the standard US 4.0 scale with plus/minus grades. If your school uses a different scale, treat the result as an approximation.
Can I calculate a semester and cumulative GPA?
Yes. Enter just this semester's courses for a semester GPA, or all courses for a cumulative GPA.
