How to calculate GPA
Quick answer: To calculate GPA, add each course, pick the scale and add your previous GPA.
- Add each course. Name (optional), credits and the letter grade.
- Pick the scale. Most schools use 4.0; some give A+ a 4.3.
- Weighted? Mark Honors or AP. These add 0.5 or 1.0 points in many high schools.
- Add your previous GPA. With your previous total credits, to get the new cumulative GPA.
The GPA formula
Multiply each course's grade points by its credits, add them up and divide by the total credits. A 4-credit A counts twice as much as a 2-credit A.
Frequently asked questions
What GPA is good?
3.0 is a B average; 3.5+ is strong for most colleges and scholarships. Requirements vary.
Do failed courses count?
Usually yes: an F is 0 points but its credits still count, which pulls the average down. Check your school's retake policy.
