Calculate GPA
Add courses, grades and credits. The calculator uses a standard 4.0 scale.
Add courses, grades, and credits
Enter each course, its grade and its credit hours. The calculator converts each grade into grade points, multiplies by credits and divides by total GPA credits.
Use the grade scale that matches your school. A 4.0 scale, weighted scale or plus and minus scale can change the result.
If a course does not count toward GPA, leave it out of the GPA credit total. Examples can include pass/fail, audit or withdrawn courses, depending on school policy.
Quality points and GPA
GPA is a credit weighted average of grade points. A 4 credit course affects the result more than a 1 credit course.
The result is not always the same as a simple average of letter grades. Credits matter.
Weighted GPA and unweighted GPA are different systems. Weighted GPA may add value for honors, AP, IB or advanced courses. Unweighted GPA usually caps grades on a standard 4.0 scale.
GPA formula
For each course, multiply grade points by credit hours. Add those quality points together. Then divide by the total number of GPA credits.
Formula: GPA = total quality points / total GPA credits.
For example, an A worth 4.0 in a 3 credit class gives 12 quality points. A B worth 3.0 in a 4 credit class gives 12 quality points.
This is why the credit column should be checked before the grade column. A wrong credit value can quietly move the final GPA.
A three-course GPA example
Suppose you have A in a 3 credit class, B in a 4 credit class and A- worth 3.7 in a 2 credit class.
Quality points are 12, 12 and 7.4. Total quality points are 31.4. Total credits are 9.
31.4 divided by 9 gives a GPA of about 3.49.
Weighted scales and repeats
The biggest mistake is ignoring credits. A high grade in a small credit class may not offset a low grade in a larger credit class.
Another mistake is using the wrong grade scale. Some schools treat A+ as 4.0. Others use 4.3 or a weighted value.
Also check repeated courses. Schools differ on whether the old attempt, new attempt or both count in GPA.
GPA Calculator FAQ
How is GPA calculated?
GPA is calculated by multiplying each course grade point by its credits, adding those quality points and dividing by total GPA credits.
This makes GPA a weighted average, not a simple grade average.
Courses with more credits have more influence on the result.
What is the difference between weighted and unweighted GPA?
Unweighted GPA usually uses the same grade point scale for all classes, often capped at 4.0.
Weighted GPA may give extra points for harder courses such as AP, IB, honors or dual enrollment.
Because schools use different weighting rules, always check the scale before comparing weighted GPAs.
Do pass/fail classes count toward GPA?
Often they do not count toward GPA, but they may still count toward earned credits. The rule depends on the school.
If a pass/fail class has no grade points, it should not be included in GPA quality points.
Check your registrar or handbook if the result is for an application or official form.
Should I include repeated courses?
It depends on your schools repeat policy. Some replace the old grade. Some average both attempts. Some keep both on the transcript but count only one in GPA.
A calculator can model the math, but the official answer comes from the school policy.
When in doubt, run both versions and compare them, then verify which rule applies.
Why does my calculated GPA not match my transcript?
The grade scale, credits, repeated courses or excluded classes may not match the transcript rules.
Weighted courses can also cause differences if you used an unweighted scale.
Compare one course at a time. Most mismatches come from a single course setting rather than the arithmetic itself.
