How GPA is calculated
Each letter grade has grade points, such as 4.0 for an A and 3.0 for a B. Multiply the points by the course credits to get quality points, add them up, and divide by total credits.
This calculator uses the common unweighted 4.0 scale with plus and minus grades. Schools differ, for example in how they treat A+ or weighted honors classes, so check your registrar’s policy for official numbers.
Worked example
A semester with an A in a 3-credit class (4.0 × 3 = 12 quality points), a B+ in a 4-credit class (3.3 × 4 = 13.2) and a C in a 3-credit class (2.0 × 3 = 6) gives 31.2 quality points over 10 credits: a semester GPA of 3.12.
With a previous cumulative GPA of 3.40 over 45 credits, the new cumulative GPA is (3.40 × 45 + 31.2) ÷ (45 + 10) = 184.2 ÷ 55 = 3.35.
Frequently asked questions
Why do credit hours matter?
GPA is weighted by credits, so a 4-credit class counts more than a 1-credit lab. Each grade’s points are multiplied by its credits before averaging.
What are pluses and minuses worth?
This calculator uses the common scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on down to D− = 0.7 and F = 0. Some schools use 3.33 and 3.67, or count A+ as 4.3, so check your school’s catalog.
Do withdrawals and pass/fail classes count?
Usually not. A W and a Pass typically earn credits (or none) without quality points, so they don’t change your GPA, but an F usually counts as 0. Policies vary, so check your registrar.
How much can one semester raise my GPA?
It depends on how many credits you already have. The more credits behind you, the more each new semester is averaged in with them, so early semesters move the number the most.
