The formula
How it works
Work out your grade point average on the standard 4.0 scale. Enter each course as a letter grade and its credit hours, and the calculator combines them into a single credit-weighted GPA.
FAQ
How does weighting by credits work?
Courses worth more credit hours count more toward your GPA. A 4-credit class has twice the pull of a 2-credit one, so the calculator multiplies each grade’s points by its credits before averaging.
What scale does this use?
The common unweighted 4.0 scale: A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0, with pluses and minuses adding or subtracting 0.3 (except A+, which stays at 4.0).
What is the difference between weighted and unweighted GPA?
An unweighted GPA, used here, treats every course the same regardless of difficulty. A weighted GPA gives extra points for honors or AP-level classes, so it can exceed 4.0.
How do I calculate my cumulative GPA?
List every course you have taken across all terms, with its grade and credit hours, in a single calculation. The cumulative GPA weights all of them together, not just one term.
Do pass/fail or audit courses affect GPA?
Usually not — pass/fail, audited and withdrawn courses are typically excluded from GPA calculations, though credits still count toward your degree requirements. Check your school’s policy, since this calculator has no way to flag those courses.
Why does A+ not count as more than 4.0?
On the standard 4.0 scale, 4.0 is the ceiling, so an A+ is usually capped at the same 4.0 as a plain A. Some schools do give A+ a value above 4.0 on their own scale, but that is less common.
How can I calculate the GPA I need next term?
Work backward from your target: multiply your desired cumulative GPA by your total credits including next term’s, subtract your current grade points, then divide by next term’s credits to see what average grade you would need.
About the GPA calculator
This calculator works out your grade point average, the single number that summarises your academic performance on a 4.0 scale. Because courses carry different amounts of credit, a GPA is not just the average of your letter grades — bigger courses count for more. This tool converts each grade to points, weights it by credit hours, and combines everything into one figure the way schools and universities do.
How to use it
List your courses in the box, each as a letter grade followed by its credit hours — for example “A 3, B+ 4, A- 3”. You can separate them with commas, spaces or new lines. The calculator converts each grade to points, weights it by credits and returns your GPA, along with your total credits and grade points. A term of A’s and B’s in mixed-credit classes typically lands around 3.5.
The formula
The GPA is the credit-weighted average of your grade points: . Each letter grade maps to points on the 4.0 scale — A is 4.0, B is 3.0, and so on — which are multiplied by that course’s credits. Adding those products and dividing by the total credits gives a number between 0.0 and 4.0.
Where it is used
GPA is central to education, used for class ranking, honour rolls, scholarship eligibility, graduation requirements and university and job applications. Students track it each term to stay on top of their progress and to work out what grades they need going forward. Because different schools use slightly different scales, checking your own institution’s system alongside this calculator is always wise.
