How is a GPA calculated?

Every course earns quality points: its grade points multiplied by its credits. The GPA is the sum of those quality points divided by the sum of the credits. Take five courses graded A over 4 credits, A− over 3, B+ over 4, A over 3 and B over 4. On the 4.0 scale that is 16 + 11.1 + 13.2 + 12 + 12 = 64.3 quality points over 18 credits, so 64.3 ÷ 18 = 3.57. The tool prints that line in full rather than only the answer.

What is the difference between a weighted and an unweighted GPA?

An unweighted GPA gives no difficulty bonus for honors, AP or IB; courses still count in proportion to their credits. Equal mode gives every counted course one unit. A weighted GPA adds points for harder courses, most commonly +0.5 for honors and +1.0 for AP or IB, which is why a weighted GPA can finish above 4.0. Using the same five courses with the first taken as AP and the second as honors, the bonus adds 1.0 × 4 credits plus 0.5 × 3 credits, so 64.3 becomes 69.8 and the GPA moves from 3.57 to 3.88. The bonus reaches passing grades only: a failed AP course is still a zero.

Is an A+ worth 4.0 or 4.3?

Both, depending on the school. Most US institutions cap the scale at 4.0 and give an A+ and an A the same 4.0. Others award an A+ 4.3, which lets a transcript pass 4.0 with no weighted courses at all. Nothing else on the scale moves between the two conventions: A− is 3.7, B+ is 3.3 and F is 0 either way. The tool makes this a control rather than an assumption, and the table under it shows the mapping in use.

How do I work out my cumulative GPA from a prior GPA?

Convert both records back to quality points and divide once. Take the same five courses: 69.8 quality points over 18 credits. Added to a prior 3.61 over 54 credits, which is 194.94 quality points, that is 264.74 quality points over 72 credits, so the cumulative is 3.68. Averaging 3.61 and 3.88 gives 3.75 and is wrong: the older, larger block of credits pulls harder. Enter the prior GPA and its credits in the Cumulative row, and pick whether the weighted or the unweighted semester figure goes in.

Do pass/fail courses count towards a GPA?

This tool excludes P, NP, W and I from both GPA credits and quality points and names each excluded course. That is the convention used here, not a universal school rule: a failing no-pass grade, an incomplete that later becomes an F, or a withdrawal can be treated differently by an institution. Check the grades and GPA-credit denominator on your transcript.

How do percentage grades convert to a GPA?

They are banded to a letter first, then the letter is scored. The bands here are 93 to 100 for an A, 90 to 92 for an A−, 87 to 89 for a B+, and so on down to under 60 for an F. Each band includes the number shown and runs up to the next one, so a 92.9 is an A− and a 93 is an A. Band edges vary between schools, which is why they are printed rather than assumed.

The tool calculates grade points times credits using the displayed scale and bonuses, then rounds the GPA display to two decimals. It cannot apply your institution's repeat, transfer, admission or grade-forgiveness policies automatically. The percentage bands are fixed to the table shown; bonus controls and the A+ choice do not make it a calculator for every school scale. Compare the included courses, GPA credits and scale with your transcript.

Can I calculate college GPA from credit hours and letter grades?

Yes, if the displayed letter scale matches your college. Enter one row per course and its GPA credit hours in Per course mode. A 4-credit A contributes 16 quality points, while a 3-credit B contributes 9: 25 divided by 7 is a 3.57 GPA. Select Equal only when each included course should have the same weight. Credit hours describe the course weight, not hours spent studying.

Can I convert a percentage or another GPA scale to 4.0?

Percentage mode maps each course percentage through the fixed bands shown, then combines the resulting grade points with course credits. It does not multiply an overall percentage by 4/100 or convert an aggregate GPA from an arbitrary 5-, 10- or 20-point scale. You need the actual grades, credits and the conversion rules of the institution receiving the record.

Can I use a transcript or try a future semester?

Enter transcript courses manually; there is no transcript upload, repeat-course detector or target-GPA solver. You can change anticipated course grades and credits to compare scenarios, then combine that term with a prior cumulative GPA. For a final exam, first work out the course grade under its syllabus; an exam percentage is not itself a GPA.

Can I calculate GPA from numerical grade points?

Yes. Open the Grade Points GPA page or choose Grade points above, then enter each course’s points per credit and its GPA credits. A 3-credit course at 3.7 points plus a 1-credit course at 3.0 gives (3.7 × 3 + 3.0 × 1) / 4 = 3.525, displayed as 3.53. Points from different grading conventions cannot be mixed as though they share a scale. Supplied honors or AP points already include any bonus, so this input mode adds none.

Are grade points, quality points and assignment points the same?

No. Grade points are the points per GPA credit assigned to a course grade. Quality points multiply that number by the course’s GPA credits: 3.7 over 3 credits is 11.1 quality points. Enter 3.7, rather than 11.1, in Grade points. Assignment earned/possible points belong to Grades Calculator; first calculate the course percentage, then apply the institution’s grade-point mapping. The Percentage to GPA page uses only its displayed bands, not a universal conversion.

Does a final GPA calculator solve a final exam score?

A final transcript GPA averages completed course grades and GPA credits; use the cumulative page to combine a prior record with the next term. A final-exam target instead needs a current course percentage, the final’s course weight and a desired course percentage; Final Grade under Grades Calculator solves that one missing score. An exam percentage is not itself a GPA, and these pages do not solve an inverse GPA target or choose your school’s grading policy.

GPA Calculator

Enter your courses and this works out the GPA on the scale you name, instead of one it picked for you: an A+ at 4.0 or at 4.3, honors and AP weighting on or off, or percentage marks banded to letters. It writes the quality points out term by term so the arithmetic can be checked, leaves P, NP, W and I grades out of the average and names the courses it dropped, and combines this term with the cumulative record you already have. Use a term, semester or full year of course rows with the same grading convention; credit hours are the weights, not study hours. Course entries and choices are saved in this browser after you edit them. Choose Grade points when your transcript already supplies each course’s points per credit; those points are used directly without another honors or AP bonus.

Grade points on the 4.0 scale

A+ and A are both worth 4.0. The most common US convention. Weighting is on, so the last two columns are in use, at +0.5 for honors and +1.0 for AP or IB. Change either figure above to match your district.

Grade	Points	Honors +0.5	AP or IB +1.0
A+	4.0	4.5	5.0
A	4.0	4.5	5.0
A−	3.7	4.2	4.7
B+	3.3	3.8	4.3
B	3.0	3.5	4.0
B−	2.7	3.2	3.7
C+	2.3	2.8	3.3
C	2.0	2.5	3.0
C−	1.7	2.2	2.7
D+	1.3	1.8	2.3

F	0.0	0.0	0.0

A failed course stays at zero however it is weighted: the honors and AP bonus applies only to a passing grade.

The scale is a convention, and this page names the one it is using. Most US schools map an A to 4.0 and an A+ to 4.0 as well; some give the A+ a 4.3, and weighting for honors and AP courses is set district by district. That pick is a control here rather than an assumption, and the table above shows every mapping currently in use. Finite browser arithmetic: quality points are grade points times credits, and GPA is their sum divided by GPA credits, displayed to two decimals. Supplied points receive no extra bonus; letter and percentage inputs use the displayed convention. Your registrar determines which courses count.

Grade to points, on both scales

The two letter scales are identical apart from the A+. The last two columns show what a course is worth once honors or AP weighting is applied to the 4.0 base, and a failed course stays at zero at every level.
