How it’s calculated
Grade points × credits for each course
4.0×3 + 3.3×4 + 3.7×3 + 2.0×2 = 40.3
Divide by total credits
40.3 ÷ 12 = 3.36
How the GPA calculator works
Each letter grade is worth a number of grade points. The calculator multiplies each course’s grade points by its credits to get “quality points”, adds them up and divides by the total number of credits. The result is your grade point average for the courses you entered.
To get a cumulative GPA, it turns your current GPA back into quality points (GPA × credits), adds this term’s points and credits, and divides again.
The grade scale used
The formula
GPA = Σ (Grade points × Credits) ÷ Σ Credits
Cumulative = (Current GPA × Current credits + Term points) ÷ All credits
Worked example
A term with four courses: an A in a 3-credit course, a B+ in a 4-credit course, an A− in a 3-credit course and a C in a 2-credit course.
- Quality points: 4.0 × 3 + 3.3 × 4 + 3.7 × 3 + 2.0 × 2 = 12 + 13.2 + 11.1 + 4 = 40.3
- Credits: 3 + 4 + 3 + 2 = 12
- Term GPA: 40.3 ÷ 12 = 3.358…, which rounds to 3.36
With a current GPA of 3.2 over 30 credits: 3.2 × 30 = 96 points. The cumulative GPA is (96 + 40.3) ÷ (30 + 12) = 136.3 ÷ 42 = 3.245…, about 3.25.
Frequently asked questions
Does my school use this scale?
Many US colleges and high schools use this 4.0 scale or something close to it, but details differ: some count A+ as 4.3, some have no minus grades, and some use a different scale altogether. Check your school’s catalogue or transcript key.
What is a weighted GPA?
Some high schools add extra points for honours, AP or IB courses, so an A might count as 5.0. This calculator works out an unweighted GPA. Your school decides how weighting works.
What about pass/fail courses and withdrawals?
They usually earn credits without grade points, so they are left out of the GPA. Do not enter them here unless your school counts them.
Why do credits matter?
A GPA is a weighted average. A 4-credit course counts twice as much as a 2-credit course, so a grade in a bigger course moves your GPA more.
My transcript shows a slightly different number. Why?
Schools round or truncate GPAs in different ways, may count repeated courses differently, and may include grades from other terms. The calculator shows the exact value in the steps so you can compare.
