How to Calculate Your Cumulative GPA
Your cumulative GPA is the average of all your grades across every semester, weighted by credit hours. To add a new semester to your existing GPA, this calculator combines your prior grade points with your new ones and divides by your total credit hours.
- Enter your current cumulative GPA — the GPA shown on your transcript so far. Leave blank if this is your first semester.
- Enter credits earned so far — the total credit hours behind that GPA.
- Add this semester’s courses — enter each course grade and its credit hours.
- Click Calculate — your new cumulative GPA appears instantly.
The Cumulative GPA Formula
Cumulative GPA is calculated by multiplying your prior GPA by your prior credits to get your total grade points, then adding the grade points from your new courses (each grade value times its credits), and dividing the total by your combined credit hours.
For example, if you have a 3.0 GPA over 60 credits and you earn straight A’s in 15 new credits, your grade points are (3.0 x 60) plus (4.0 x 15) = 180 plus 60 = 240, divided by 75 total credits = a 3.2 cumulative GPA.
Frequently Asked Questions
Your semester GPA is the average of just the courses you took in one term. Your cumulative GPA is the average across every course you have ever taken, weighted by credit hours. This calculator shows both: the new cumulative GPA and the semester GPA for the courses you entered.
Most college courses are worth 3 credit hours, though labs and seminars can be 1 or 2, and some intensive courses are 4 or 5. Check your syllabus or transcript for the exact credit value of each course.
It depends on how many credits you already have. Early on, a single semester moves your cumulative GPA a lot because you have few total credits. The more credits you accumulate, the more each new semester is diluted, so one weaker term has less impact later in your studies.
Raising a cumulative GPA gets harder as you earn more credits, because each new grade is a smaller share of the total. The most effective approach is consistently strong semesters and, where your school allows it, retaking courses where you earned low grades to replace them.
A cumulative GPA of 3.0 is generally considered good, 3.5 and above is strong, and 3.7 or higher often qualifies for honors like cum laude. Many graduate programs and scholarships look for a 3.0 minimum, though competitive programs expect higher.
