Your overall GPA is an average of everything, including the introductory course you took in first year to fill a requirement and the elective you chose because it sounded easy. Your major GPA throws all of that out and keeps only the courses in your subject. It is the number graduate schools, honours committees and a lot of employers actually ask for, and it is often a fair bit different from the one on your transcript header.
This calculator takes your major courses one at a time. Course name, grade in GPA points, credit value. Add a row for each one, press Calculate Major GPA, and it gives you the weighted average plus the total credits and course count behind it.
One honest detail before you start: you enter grades as points, not letters. A is 4.0 and B+ is 3.3 on the standard scale, and if your school runs a 4.33 scale, a 4.0 scale where A+ is worth extra, or straight percentages, you need to convert before you type anything in. The calculator does not know your institution’s rules.
Calculate the GPA for your major courses only, separate from your overall GPA. Add each major course with its grade and credits, then calculate.
How it works
One course row is already waiting for you. Fill in the grade and the credits, then press Add Course and another row appears underneath. There is no fixed limit on the number, so a whole degree programme fits. Press Calculate Major GPA when every row has both numbers in it.
The arithmetic is one weighted mean. Each course contributes grade points multiplied by credits to a running total, and the credits go into their own total. The final figure is the sum of grade points divided by the sum of credits, shown to two decimal places along with a line telling you how many credits across how many courses produced it.
Any row missing a grade or a credit value gets flagged by its row number instead of being quietly skipped, because a silently dropped course is how someone ends up with a major GPA that looks too good. Reset clears every row and the result and leaves you back at the start. The result always carries a note reminding you that it is an estimate to confirm against your institution.
A worked example
Five major courses: Organic Chemistry, 4 credits, grade 4.0. Calculus II, 3 credits, grade 3.3. Physics I, 4 credits, grade 3.7. Statistics, 3 credits, grade 3.0. Biology II, 4 credits, grade 4.0.
Multiplying each grade by its credits gives 16.0, 9.9, 14.8, 9.0 and 16.0. Add them and you get 65.7 grade points. The credits add to 4 + 3 + 4 + 3 + 4 = 18. Divide and the tool reports Major GPA: 3.65, summarised as across 18 credits in 5 courses.
Three courses at 3 credits each, graded 3.7, 3.3 and 4.0, give 11.1 + 9.9 + 12.0 = 33.0 over 9 credits, which is 3.666 recurring and comes back as 3.67. One 4-credit course graded 3.0 gives 3.00, because a single course is its own average. And a part-time term of one 3-credit course at 4.0 gives 4.00, which is worth remembering before you read too much into a major GPA built from very few credits.
What counts as a major course
That depends on your program, and it is the part people get wrong rather than the division. Some departments count only the required courses in the major field, others include electives taken inside the subject, and a few count a statistics or methods course that sits in a different faculty. Check your degree audit or ask the department before you decide which rows to add.
Retakes are the other trap. Some institutions replace the original grade entirely, some average the two attempts, and some count both. If you repeated a major course, find out which rule applies before you enter it, because entering both attempts on a replace rule inflates the credits and drags the average the wrong way.
Courses from a previous major usually do not belong in this list. They sit as electives or general education on your transcript, and including them turns the number back into something closer to your cumulative GPA. If you changed majors, add only what counts toward the current degree.
Watch the scale too. A B+ is 3.3 on the standard scale and 3.5 on a 4.33 scale, and a percentage system needs converting first. Getting that wrong shifts every course at once, which is a bigger error than a single mis-typed grade.
How good a major GPA is good
3.5 and up is generally strong in the major, and competitive graduate programs often want 3.7 or higher, though the bar moves a lot by field. A strong major can rescue an overall GPA weakened by a rough first year, which is exactly why admissions offices look at the two separately. It works in reverse too: an easy elective load can hold a cumulative GPA above what your subject grades would produce on their own.
Small credit totals read badly in both directions. Two courses will swing a long way on one grade, so treat a major GPA built from under 12 credits as a snapshot rather than a track record.

Frequently asked questions
What is a good major GPA?
3.5 or higher is generally considered strong, and competitive graduate programs often look for 3.7 or above within the subject. What counts as good varies by field, so the specific programme you are applying to is the only authority worth checking against.
Do all my major courses count?
Only the ones your program defines as counting toward the major, and that differs between departments: some count required courses only, others include electives inside the subject. Your degree audit lists them, and it is worth looking before you enter anything.
Is major GPA the same as cumulative GPA?
No. Cumulative includes every course on your record, major keeps only the ones in your subject. They can be quite far apart if you did badly in your first year or if you padded the transcript with light electives.
What if I changed majors?
Enter only the courses that count toward your current major. Anything from the old subject sits as elective or general education credit, and including it just pulls the figure back toward your overall average.
Why does it say the result is an estimate?
Because it is doing the arithmetic you gave it and nothing more. Your institution decides which courses count, how retakes are handled and which point scale applies, so the number here should be confirmed against your transcript or a departmental audit before you quote it on an application.
