College Board's chart, checked Oct 7, 2026, prints whole numbers only (B is 80-89, D is 66-69). We read a score between two rows, like 89.5, as the lower row, and start D at 65.
Cumulative GPA
Your earlier GPA was already rounded, so this can be a hundredth off your school's figure.
GPAs here are rounded half-up to 2 decimals, with the exact value beside them. Your school may round differently or show more decimals.
Your school's GPA is the official one, and colleges often recompute it with their own rules.
How the GPA calculator works
Every letter on your report card turns into points. On the 4.0 scale an A is 4.0, a B+ is 3.3 and a C is 2.0. Multiply each class's points by its credits, add those up, and divide by all the credits together. That's your semester GPA. If every class carries the same credit, it's just the average of your points: College Board's own example has three A's, a B and a C making a 3.4.
Credits start to matter the moment they differ. A B- in a four-credit calculus class pulls much harder than an A- in a one-credit lab. The table in the result card shows each class's share, so you can watch that happen line by line.
Your weighted GPA adds a bonus for harder classes. We use South Carolina's bonus sizes: half a point for honors, a full point for approved AP or IB and eligible dual-credit courses. We apply those sizes to the letter scale you pick. So an A worth 4.0 in an AP class counts 5.0. Your school may use other numbers, and you can change both. Our preset gives a grade worth 0 points no bonus.
We never average two GPAs to get your cumulative. We multiply your earlier GPA by your earlier credits, add this semester's points and divide by every credit you've earned. The shortcut really does mislead: averaging a 3.08 and a 2.98 says 3.03, while 45 earlier credits and 14 this semester make the real answer 3.06.
The goal line runs that formula backward. It rounds the semester GPA you'd need up, never down, so following it can't leave you a hundredth short. And if no semester could get you there, it tells you straight and shows what it would take.
We work every figure out exactly, without the tiny rounding errors computers make with fractions. That's why an exact 3.335 shows as 3.34 here, not 3.33.
Percentages go through College Board's chart, with one wrinkle we'd rather tell you about: the chart prints a D as 66 to 69 and an F as below 65, so 65 itself has no row. We count a 65 as a D. The chart also sticks to whole numbers, so decimals are our call too: an 89.5 stays a B, because the A row starts at 90.
| Grade | 4.0 scale | 4.3 scale | 4.33 scale |
|---|---|---|---|
| A+ | 4.0 | 4.3 | 4.33 |
| A | 4.0 | 4.0 | 4.00 |
| A- | 3.7 | 3.7 | 3.67 |
| B+ | 3.3 | 3.3 | 3.33 |
| B | 3.0 | 3.0 | 3.00 |
| B- | 2.7 | 2.7 | 2.67 |
| C+ | 2.3 | 2.3 | 2.33 |
| C | 2.0 | 2.0 | 2.00 |
| C- | 1.7 | 1.7 | 1.67 |
| D+ | 1.3 | 1.3 | not used |
| D | 1.0 | 1.0 | 1.00 |
| D- | 0.7 | 0.7 | not used |
| F | 0.0 | 0.0 | 0.00 |
Weighted GPA adds 0.5 for honors and 1.0 for AP, IB or dual enrollment to any grade above 0, unless you change them.
Who this is for
A high-school student with a fresh report card and a counselor meeting next week. A college student checking whether this semester keeps a scholarship's 3.0 floor. A parent at the kitchen table who wants to see where the portal's number comes from. And anyone whose school counts an A+ differently from the first calculator they tried.
What it won't do is tell you the grade you need on a final exam. That's a different sum, done inside one class.
Student questions about GPA
What's the difference between weighted and unweighted GPA?
Unweighted GPA puts every class on the same scale, so an A is 4.0 in regular English and in AP English alike. Weighted GPA hands out extra points for harder classes like honors and AP, which is how it can climb past 4.0. Your report card or transcript says which one your school prints. The calculator shows both, side by side, as soon as you mark a class honors or AP.
How much does an AP or honors class add to my GPA?
That's up to your school. Our preset uses South Carolina's bonus sizes: half a point for honors and a full point for approved AP or IB and eligible dual-credit courses. Applied to our starting letter scale, a B in an AP class counts 4.0 instead of 3.0. If your handbook says something else, open Honors and AP points and change the numbers. Here, a grade worth 0 points gets no bonus.
Is an A+ a 4.3 or a 4.0?
Both exist. At Stanford an A+ is worth 4.3, at Columbia's School of General Studies it's 4.33, and at the University of Michigan-Dearborn it counts the same as an A, 4.0. Pick the scale your school uses. And if there's no A+ on your report card, relax: the 4.0 and 4.3 scales give you exactly the same GPA.
How do I calculate my cumulative GPA?
Multiply your earlier GPA by your earlier credits, add this semester's grade points, and divide by all the credits together. Don't average the two GPAs. A 3.08 over 45 credits and a 2.98 semester over 14 credits make a 3.06. A plain average says 3.03, because it treats 14 credits as if they were 45. One catch: your earlier credits have to be in the same unit as this semester's.
How do I convert a percentage to GPA?
Turn each percentage into a letter, then the letter into points. College Board's chart puts 90 and up at an A (4.0), 80 to 89 at a B (3.0), 70 to 79 at a C (2.0) and 66 to 69 at a D (1.0), with anything below 65 an F. That leaves 65 itself out, so we count 65 as a D. If your school draws the lines elsewhere, change them under Points for each grade.
What is 89.5 in GPA?
It's a B here, worth 3.0. College Board's A starts at 90, and the calculator never rounds a percentage up for you. The chart only prints whole numbers, so putting an 89.5 in the B row is our reading of it. If your report card already says 90, type 90 and you've got your A. If your school's A starts lower, set its cut-off under Points for each grade.
Can a GPA be higher than 4.0?
An unweighted GPA can't go past the top of its scale: 4.0, or 4.3 and 4.33 where an A+ counts extra. A weighted GPA can, because honors and AP classes add points. With the starting values here, straight A's in AP classes make a 5.0. That's also why a weighted 4.2 and an unweighted 3.8 can describe the very same report card.
Does an F count toward my GPA?
Yes. An F is worth 0 points, but its credits still count, so it drags the average down hard. Stanford's own example: an A and a no-pass in two four-unit classes make a 2.0, not a 4.0. Pass/fail, withdrawn and audited classes are another matter. Stanford leaves W and credit marks out of its GPA, and the University of Michigan-Dearborn leaves out classes taken pass/fail. Check your school's rules and leave out here whatever it leaves out.
Do colleges look at weighted or unweighted GPA?
Possibly neither, at least not as printed. College Board says colleges may recalculate your GPA by their own criteria: some drop noncore classes like physical education, and some adjust or remove honors and AP weighting. That's why many of them ask for your actual grades. If one college matters a lot to you, ask its admissions office how it reads GPA. Your school's number is still the official one.
What semester GPA do I need to raise my cumulative GPA?
It depends on how many credits you already have behind you. Open Add your earlier GPA and a goal, type your earlier GPA, your earlier credits and the cumulative you want, and the calculator works backward, rounding up. With the example report card and an earlier 3.52 over 20 credits, a 3.60 goal needs at least a 3.87 this semester. A 3.80 goal would take a 4.74, more than any semester on the 4.0 scale can give, and the page tells you so.
How to calculate GPA on a 4.0 scale
Write down each class's grade and credits. Turn every grade into points: on the 4.0 scale an A is 4.0, an A- is 3.7, a B+ is 3.3, and so on down to 0.7 for a D- and 0 for an F. Multiply each class's points by its credits, add the results, and divide by the total credits.
Six one-credit classes with an A-, a B+, a B, a B-, an A and an A come to 20.7 points, and 20.7 divided by 6 is a 3.45. Make two of them honors and one AP, add their bonuses, and the weighted GPA is 22.7 divided by 6, a 3.78.
Percentage to GPA
With percentages, find each letter first. On College Board's chart that's 90 and up for an A, 80 for a B, 70 for a C, 65 for a D by our reading, and anything lower for an F. Then turn the letters into points and divide by credits as usual. Don't round the percentage first: an 89.5 stays a B here.
Semester GPA and cumulative GPA
Your semester GPA covers this term's classes. Your cumulative GPA covers every graded class so far, and it moves more slowly the more credits you've piled up. With 20 earlier credits and 6 this term, this semester carries a little under a quarter of the weight.
