GPA Calculator
Letter grades in, GPA out — weighted, unweighted, semester or cumulative, on the 4.0 scale.
Calculate your college or high school GPA on the standard US 4.0 scale. Enter each course's letter grade and credit hours; the calculator sums the quality points and divides by credits. Switch to Standard to weight Honors (+0.5) and AP/IB (+1.0) classes, Detailed to fold this semester into your cumulative GPA, or Advanced to solve for the average you need to reach a target GPA.
Standard 4.0-scale conventions — a planning guide only. Your school sets the official scale, weighting caps and rounding; the registrar's number is the one that counts.
How GPA is calculated on the 4.0 scale
Letter grades become grade points
Every letter grade maps to grade points on the standard US scale. Multiply each course's grade points by its credit hours to get quality points, add them up, and divide by the total credit hours:
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | C- | 1.7 |
| B | 3.0 | D+ / D / D- | 1.3 / 1.0 / 0.7 |
| B- | 2.7 | F | 0.0 |
Worked example
An A in a 3-credit course earns 4.0 × 3 = 12.0 quality points; a B+ in a 3-credit earns 9.9; a B in a 4-credit earns 12.0; an A- in a 3-credit earns 11.1. That's 45.0 quality points across 13 credit hours, so the GPA is 45 ÷ 13 = 3.46. Notice the 4-credit B counts as much as the 3-credit A — credit hours weight every course's pull on the average, which is why a heavy lab or seminar course moves your GPA more than a 1-credit elective.
Semester vs cumulative. A semester (term) GPA averages only that term's courses. Your cumulative GPA averages everything on your transcript — this calculator folds the two together at the Detailed level using your prior GPA and prior credits. Pass/fail courses earn credits but no quality points, so they sit outside the GPA entirely.
Weighted vs unweighted GPA — Honors, AP and IB
The common weighting convention
| Course type | Boost | An A counts as |
|---|---|---|
| Regular | — | 4.0 |
| Honors | +0.5 | 4.5 |
| AP / IB (and often dual enrollment) | +1.0 | 5.0 |
A weighted GPA rewards course rigor: the boost is added to the course's grade points before the credit-weighted average, so a schedule heavy in AP or IB classes can produce a GPA above 4.0. An unweighted GPA ignores rigor and stays on the plain 4.0 scale. This calculator shows both whenever any course is marked Honors or AP/IB.
Where each number gets used
High schools generally use the weighted GPA for class rank and honors recognition, because it stops a student from protecting a 4.0 by avoiding hard classes. Colleges mostly treat a reported weighted GPA as a starting point: many recalculate onto their own scale — often unweighted, core academic courses only — and judge rigor separately from the transcript. Scholarship and NCAA cutoffs each specify which GPA they mean.
Caps vary. The +0.5/+1.0 convention is the most common, but schools differ: some cap the weighted scale at 4.5 or 5.0, some boost only semester grades of C or better, and boosts almost never apply to an F. Your student handbook has the exact policy.
Cumulative GPA and reaching a target
Folding in past semesters
Your cumulative GPA is just the same quality-points math over your whole transcript. If you know your prior cumulative GPA and prior credit hours, this semester folds in as: cumulative = (prior GPA × prior credits + this semester's quality points) ÷ (prior credits + this semester's credits). Enter both at the Detailed level and the hero number becomes your updated cumulative GPA.
Solving for a target
The Advanced level answers the question students actually ask: what average do I need from here? To reach a target GPA after N more credits: needed = (target × (current credits + N) − current quality points) ÷ N. Worked example: with 60 credits at 2.8 (168 quality points), reaching a 3.0 by 90 credits needs (3.0 × 90 − 168) ÷ 30 = 3.40 over the next 30 credits — a sustained B+/A- run. If the answer comes out above 4.0, the target isn't reachable in that many credits: plan more semesters, or adjust the target.
Why GPA gets harder to move
Because it's a credit-weighted average, every new course carries less leverage as your transcript grows. A freshman can move a GPA half a point in one strong semester; a senior with 100+ credits barely shifts it. That cuts both ways — early struggles fade slowly, but an early strong base is durable. If your school offers repeat/replace (retaking a course to replace the old grade in the GPA), it's often the fastest single lever — policies differ, so ask your registrar.
What's a good GPA? Dean's List, NCAA and other cutoffs
| Benchmark | Typical GPA | Notes |
|---|---|---|
| Dean's List | ~3.5+ term GPA | Set per college; some use 3.6 or 3.7, most require a minimum credit load |
| High school honor roll | ~3.0 / 3.5+ | Honor roll vs high honor roll; criteria vary by district |
| Typical college average | Around 3.0 | A B average — varies by school and major |
| Graduate school admissions | 3.0+ floor common | Competitive programs often expect 3.5–3.7+ |
| NCAA Division I eligibility | 2.3 core-course GPA | Calculated by the NCAA Eligibility Center over 16 core courses; Division II is 2.2 |
| Good academic standing | 2.0 cumulative | Also the usual line in schools' satisfactory academic progress policies for federal aid |
Context matters more than the raw number: a 3.4 in a notoriously hard engineering program reads differently from a 3.4 in an easier one, and employers and graduate programs know it. Above roughly 3.5, internships and grad programs mostly stop differentiating on GPA and look at everything else. Below 2.0, the urgent issues are academic standing and financial-aid eligibility — talk to your advisor before the semester ends, not after grades post.
❓ Frequently asked Frequently asked questions
How do I calculate my GPA?
Convert each letter grade to grade points on the 4.0 scale (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0), multiply by the course's credit hours to get quality points, add them all up, and divide by total credit hours. Example: an A in a 3-credit course (12.0 points), a B+ in a 3-credit (9.9), a B in a 4-credit (12.0) and an A- in a 3-credit (11.1) total 45.0 quality points across 13 credits — a GPA of 45 ÷ 13 = 3.46. Note the 4-credit B pulls harder than a 3-credit grade would: credit hours weight every course's influence.
What is the difference between weighted and unweighted GPA?
An unweighted GPA scores every class on the plain 4.0 scale regardless of difficulty. A weighted GPA adds a boost for harder courses — most commonly +0.5 for Honors and +1.0 for AP or IB — so an A in an AP class counts as 5.0 and a weighted GPA can exceed 4.0. High schools typically use weighted GPA for class rank; colleges usually recalculate applicants' GPAs onto their own scale, often unweighted and using core academic courses only. Caps and exact boost values vary by school, so check your handbook.
Is an A+ a 4.0 or a 4.3?
On the most common US scale, an A+ carries the same 4.0 as an A — that is the convention this calculator uses. A minority of schools award 4.3 for an A+ (and some give no A+ at all), which is why you occasionally see unweighted GPAs above 4.0. If your transcript uses a 4.3-max scale your official GPA will run slightly higher than the number here, but the relative ranking of your grades is unchanged. Use whatever scale the receiving school or application asks for.
What GPA do I need for the Dean's List or honor roll?
There is no single national cutoff — each college sets its own — but Dean's List thresholds most commonly sit at a 3.5 term GPA, with some schools using 3.6 or 3.7 and many also requiring a minimum number of graded credits that term. In high school, honor roll cutoffs are typically a 3.0 (B average) for honor roll and around 3.5+ for high honor roll. Check your school's published criteria: some exclude pass/fail credits or require no grade below a B.
What GPA does the NCAA require?
NCAA Division I requires at least a 2.3 GPA in your 16 core high-school courses to be a full qualifier; Division II requires a 2.2 core-course GPA. This core-course GPA is not your overall school GPA — the NCAA Eligibility Center recalculates it from your transcript using only approved core courses (English, math, natural/physical science, social science and certain others) on an unweighted 4.0 scale. Details and the core-course lists are at ncaa.org.
How do colleges recalculate high school GPA?
Most admissions offices don't take a transcript GPA at face value. They commonly recalculate using only core academic courses (dropping PE, health and electives), convert everything onto their own scale, and either strip weighting entirely or apply their own bonus for AP/IB/Honors rigor. That means two applicants with the same reported GPA can be read very differently, and rigor is often assessed separately from the number. Report your GPA exactly as your school calculates it and let each college do its own conversion.
Can I raise a 2.8 GPA to a 3.0?
Yes, if enough credits remain — GPA is a credit-weighted average, so the math depends on how much of your transcript is still ahead of you. With 60 credits at 2.8, reaching a 3.0 cumulative by 90 credits requires (3.0 × 90 − 2.8 × 60) ÷ 30 = 3.40 over your next 30 credits — a solid B+/A- run, demanding but realistic. The Advanced level of this calculator solves this for any target and flags the ones that would need better than a 4.0, which tells you to allow more semesters or adjust the goal.
Do pass/fail classes count toward GPA?
Generally no. A passed pass/fail (or credit/no-credit) course earns credits toward graduation but no quality points, so it is excluded from the GPA calculation entirely — that's why this calculator has no P grade. Beware the fail side: at many schools a failed pass/fail course posts as an F and does hit your GPA. Pass/fail credits usually still count as attempted credits for financial-aid satisfactory academic progress, and some graduate and professional schools recalculate or frown on heavy pass/fail use in prerequisite courses.
Where these figures come from
The 4.0 grade-point mapping and the +0.5/+1.0 Honors and AP/IB weighting are long-standing US conventions rather than regulations — every school publishes its own scale in its handbook or transcript key, and that document is the authority for your official GPA. The specific cutoffs quoted on this page come from these sources:
- NCAA core-course GPA minimums (2.3 Division I / 2.2 Division II) — NCAA — Eligibility Center.
- Satisfactory academic progress and GPA for federal student aid — Federal Student Aid — Staying Eligible.
- How GPA and course rigor are read in college admissions — College Board — BigFuture.
Last checked: July 2026. Dean's List, honor roll, academic-standing and repeat/replace policies are set by individual schools and vary; the figures here are the common conventions, not a substitute for your institution's published rules.
Select the question that matches where you are right now.
The headline number is your GPA to two decimals on the 4.0 scale — semester by default, cumulative once you add prior credits, weighted once any course is marked Honors or AP/IB.
Read it against the cutoff you care about — Dean's List (~3.5+), a scholarship's renewal line, a grad program's 3.0 floor, the NCAA's 2.3 core minimum, or your school's 2.0 good-standing line — and plan the semester accordingly.
It's not your official GPA. Schools differ on A+ handling, weighting caps, rounding, repeat/replace and which courses count. Your registrar's calculation on the transcript is the number colleges and employers see.
That's normal — AP/IB boosts push weighted GPAs past 4.0. Just never mix the two scales: report weighted and unweighted separately, exactly as each application asks.
Three things drive the number: the grade points each letter earns, the credit hours behind each course, and how much transcript already sits underneath.
A 4-credit course counts a third more than a 3-credit one. A rough grade in a heavy lab course costs more than the same grade in a 1-credit elective — and an A there pays more too.
The 0.3-point steps look small, but a semester of A- instead of A is the difference between a 4.0 and a 3.7 — a Dean's List line at some schools. The steps compound across a transcript.
The more credits behind you, the less each new one moves the average. That's why the target planner divides by the credits you have left: the same target gets steeper every semester you wait, until it quietly crosses above 4.0 and out of reach.
A GPA is raised course by course — but some levers are bigger than others.
Set your goal and the credits you have left on the Advanced level. A concrete "3.40 over the next 30 credits" turns a vague hope into a per-semester plan you can actually check.
Many schools let a retaken course replace the original grade in the GPA (the F often stays on the transcript). Replacing one F with a B can outdo a whole semester of marginal gains.
Put your effort where the credit hours are, use withdrawal deadlines before an F posts, and keep pass/fail for true electives — a P protects nothing if your program later wants a graded prerequisite.
