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.
| Course | Grade | Credits | Level | Points | Remove course |
|---|---|---|---|---|---|
No grades yet. Choose a grade for at least one course, with the credits it carries, and the GPA appears here.
Cumulative
Add the record you already have and this combines the two by quality points, which is not the same as averaging the two GPAs. The semester figure comes from the courses above.
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 |
| D | 1.0 | 1.5 | 2.0 |
| D− | 0.7 | 1.2 | 1.7 |
| 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.
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.
| Grade | 4.0 scale | 4.3 scale | Percentage band | With honors +0.5 | With AP or IB +1.0 |
|---|---|---|---|---|---|
| A+ | 4.0 | 4.3 | Counted as A | 4.5 | 5.0 |
| A | 4.0 | 4.0 | 93 to 100 | 4.5 | 5.0 |
| A− | 3.7 | 3.7 | 90 to 92 | 4.2 | 4.7 |
| B+ | 3.3 | 3.3 | 87 to 89 | 3.8 | 4.3 |
| B | 3.0 | 3.0 | 83 to 86 | 3.5 | 4.0 |
| B− | 2.7 | 2.7 | 80 to 82 | 3.2 | 3.7 |
| C+ | 2.3 | 2.3 | 77 to 79 | 2.8 | 3.3 |
| C | 2.0 | 2.0 | 73 to 76 | 2.5 | 3.0 |
| C− | 1.7 | 1.7 | 70 to 72 | 2.2 | 2.7 |
| D+ | 1.3 | 1.3 | 67 to 69 | 1.8 | 2.3 |
| D | 1.0 | 1.0 | 63 to 66 | 1.5 | 2.0 |
| D− | 0.7 | 0.7 | 60 to 62 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0 to 59 | 0.0 | 0.0 |
| P, NP, W, I | Not counted | Not counted | Not counted | Not counted | Not counted |
Common questions
- 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 treats every course the same. 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?
- No. P, NP, W and I carry credits at some schools and none at others, but nowhere do they carry quality points, so they cannot move an average. The tool leaves them out of both the credits and the quality points, and lists the courses it excluded by name so nothing disappears silently.
- 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.
- Is this GPA exact?
- The arithmetic is exact for the scale shown, and the working is printed so it can be checked line by line. What it cannot know is your school's own convention: whether an A+ is 4.0 or 4.3, how much an honors course is worth, where the percentage bands sit, and whether repeated or transfer courses are included. Set the controls to match your transcript and the number will match your registrar's.
Exact arithmetic on the scale shown: quality points are grade points times credits, and the GPA is their sum divided by credits. Which points a school assigns to an A+ and how it weights honors and AP courses vary; the controls state the convention used, and your registrar's figure follows their own.
