What is a college GPA?

Enter each class’s letter grade and credits above, and you get your college GPA: a credit-weighted average of your grades on a 4.0 scale. Add earlier semesters or your current GPA, and you’ll see your cumulative GPA too.

Use it when grades post, before you drop or add a class, or when a scholarship, major or internship asks for a GPA. It also shows your major GPA and the average you’d need next term. It won’t predict a class grade from your scores or apply your school’s retake rule; the Related calculators below handle those.

Your semester GPA covers one term. Your cumulative GPA combines the courses included across terms, weighted by credits.

How to use the college GPA calculator

Three steps get you a result, and your work saves on this device as you go.

1. Set your scaleThe line above the rows reads “Standard 4.0 scale · Use your school’s scale”. Tap Use your school’s scale to load one of 90 university scales, or open Options ▾ for an A+ = 4.33 scale or your own values.
2. Enter each classPick a Grade and Credits for every row. The course name is optional. Use + Add class for more rows and + Add semester for each new term, so you see your GPA per semester and your cumulative GPA.
3. Add your historyIn Options ▾, turn on Add previous GPA to enter your current cumulative GPA and its credits. Use the GPA hours shown next to that GPA on your transcript, not your total earned credits. Turn on Major GPA to tick the classes in your major.

Understanding your results

Load the sample grades and the result panel shows five things:

In the result	Sample	What it means
Cumulative GPA	3.34	Every class, weighted by credits
Credits · Classes · Quality points	26 · 8 · 86.8	The totals behind it: 86.8 ÷ 26
Major GPA	3.15	Only the classes you tick as your major
Biggest lever	+0.06	The one grade change that helps most
GPA planner	3.78	The average you need next term for your target

How to calculate college GPA

You multiply each grade’s points by the class credits, add those up, and divide by the credits that count. A 4-credit class pulls harder than a 2-credit one.

Semester GPA Calculation

Say your fall semester looks like the sample grades:

Grade → points × creditsQuality pts

Worked example: a four-course college semester, from letter grades to a 3.41 GPA

Course	Grade		Grade points		Credits		Quality points
ENG 101 — English Composition	A	→	4.0	×	3 cr	=	12.0
MATH 121 — Calculus I	B+	→	3.3	×	4 cr	=	13.2
PSY 201 — Intro to Psychology	A–	→	3.7	×	3 cr	=	11.1
BIO 110 — General Biology	C+	→	2.3	×	2 cr	=	4.6
Total quality points 40.9 ÷ Credits counted 12 = GPA 3.41

That’s 12.0 + 13.2 + 11.1 + 4.6 = 40.9 quality points over 12 credits, an unweighted 3.41. Averaging the four grade points instead gives 3.33, because it treats the 2-credit C+ like a 4-credit class.

Spring adds MATH 122 (B, 4), CHEM 101 (B−, 4), HIST 110 (A, 3) and COMM 120 (A−, 3). That’s 45.9 quality points over 14 credits, a 3.28 semester GPA.

Cumulative GPA Calculation

For your cumulative GPA, add the quality points and credits from both semesters, then divide. Don’t average the two GPAs:

Semester totalsQuality pts ÷ credits

Cumulative GPA: 86.8 quality points over 26 credits = 3.34

Semester	Semester GPA	Quality points		Credits
Fall semester	3.41 GPA	40.9	÷	12 cr
Spring semester	3.28 GPA	45.9	÷	14 cr
Total quality points 86.8 ÷ Credits counted 26 = Cumulative GPA 3.34

Averaging the two semester GPAs instead gives 3.35, because it treats the 12-credit fall like the 14-credit spring.

How to calculate GPA on the quarter system

On the quarter system, your GPA uses the same math as a semester. You still weight each grade by its units and divide by the units that count; you just have three terms a year instead of two.

Say your fall quarter looks like this:

Grade → points × creditsQuality pts

Fall quarter: 44.5 quality points over 13 units = 3.42

Course	Grade		Grade points		Credits		Quality points
ENGL 1A	A	→	4.0	×	4 cr	=	16.0
MATH 3A	B+	→	3.3	×	5 cr	=	16.5
PSYC 1	B	→	3.0	×	4 cr	=	12.0
Total quality points 44.5 ÷ Credits counted 13 = GPA 3.42

That’s 16.0 + 16.5 + 12.0 = 44.5 quality points over 13 units, a 3.42. In the calculator, type each class’s quarter units into Credits and use + Add semester for every quarter. The button says semester, but it works for any term, so winter and spring stack into one cumulative GPA.

What is a good college GPA?

On a standard 4.0 scale, 3.0 represents a B average and 3.5 falls between B+ and A−. Whether that meets your goal depends on the scholarship, major, honors or graduate program you’re targeting, so check its minimum and compare your result with it.

GPA band	What to check next
3.50–4.00	Honors and competitive programs set their own cutoffs
3.00–3.49	Scholarship and graduate-program minimums
2.00–2.99	Major and program minimums
Below 2.00	Academic standing and financial aid; talk to an advisor now

If you get federal aid, check your college’s satisfactory academic progress policy too. For programs longer than two years, federal rules require at least a C average by the end of the second year, or standing consistent with graduation.

Which classes count toward college GPA?

Your college decides which courses and grades count toward your GPA, so a calculator and a transcript can disagree by a few hundredths. These rules differ most:

• Pass, no pass and withdrawn: no grade points at Georgia Tech or Southern Indiana. The calculator leaves out P, NP and W.
• Incompletes: no points until graded. At some colleges, one left unfinished past a deadline becomes an F.
• Transfer, AP and IB credit: can count toward your degree but not your GPA. Georgia Tech and Southern Indiana leave transfer grades out, and some colleges treat AP and IB exam credit the same way.
• Retakes: Georgia Tech counts both attempts; other colleges count only the highest or latest grade.
• Rounding: Georgia Tech truncates (3.408 → 3.40); this calculator rounds (3.41).

College GPA scale: letter grades to grade points

The calculator’s standard scale gives plus and minus grades these points. Some schools differ: Southern Indiana gives a B+ 3.5, and Options ▾ offers an A+ = 4.33 version.

Letter grade	Percentage	Grade points
A+ / A	93–100%	4.0
A−	90–92%	3.7
B+	87–89%	3.3
B	83–86%	3.0
B−	80–82%	2.7
C+	77–79%	2.3
C	73–76%	2.0
C−	70–72%	1.7
D+	67–69%	1.3
D	63–66%	1.0
D−	60–62%	0.7
F	below 60%	0.0
