High School GPA Calculator — Weighted and Unweighted GPA
Calculate your unweighted GPA (4.0 scale) and weighted GPA (5.0 scale) for all course levels including Regular, Honors, AP, IB, and Dual Enrollment — instantly and simultaneously.
Your high school GPA is the primary academic metric used for college admissions, scholarships, athletic eligibility, and class rank determination. Unlike college GPA, high school GPA involves two parallel scales — an unweighted GPA that treats all courses equally on the 4.0 scale, and a weighted GPA that rewards course rigor by adding bonus points for Honors, AP, and IB coursework.
This calculator serves high school students in all grades planning for college, parents tracking their student's academic standing, and school counselors advising on college eligibility. It also calculates your target GPA requirements and checks NCAA athletic eligibility thresholds. For college GPA, use the Cumulative GPA Calculator.

Unweighted vs Weighted GPA — What's the Difference and Which Matters More?
High school students carry two GPAs simultaneously. Understanding what each measures — and how colleges use both — is essential for planning your academic strategy. See the 4-Point GPA Scale and 5-Point GPA Scale for complete scale references.
An A in PE and an A in AP Physics both contribute 4.0 to the unweighted GPA. Scale runs from 0 to 4.0 — it never exceeds 4.0.
Why it matters: Most straightforward for cross-school comparison. Many colleges recalculate only this number when evaluating applications.
Honors: +0.5 bonus. AP and IB: +1.0 bonus. An A in AP contributes 5.0 vs 4.0 for regular. Can exceed 4.0 — maximum is typically 5.0.
Why it matters: Signals course rigor in a single number. Students who take harder courses and earn slightly lower grades can still show strong academic drive.
Student A — All Regular Courses
| Course | Level | Grade |
|---|---|---|
| English 11 | Regular | A |
| Algebra II | Regular | A |
| Biology | Regular | A |
| US History | Regular | A |
| Spanish II | Regular | A |
| GPA | 4.0 / 4.0 | |
Student B — Mix of AP and Regular
| Course | Level | Grade |
|---|---|---|
| AP English Lang | AP | A |
| AP Calculus AB | AP | B |
| AP Chemistry | AP | A- |
| AP US History | AP | A |
| Spanish III | Regular | A |
| Unweighted | 3.84 | 4.74 weighted |
Student B has a lower unweighted GPA (3.84 vs 4.0) but took 4 AP courses. Most selective college admissions officers view Student B's application more favorably because course rigor demonstrates willingness to challenge oneself academically.
Weighted GPA Scale — AP, IB, Honors, and Dual Enrollment Grade Points
The complete weighted grade scale for all course levels. See the 5-Point GPA Scale for a full explanation of the weighted system.
| Grade | Regular (4.0) | Honors (+0.5) | AP / IB (+1.0) |
|---|---|---|---|
| A+ / 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 |
| F | 0.0 | 0.0 | 0.0 |
The AP bonus outweighs the 0.3 grade difference
Honors bonus exceeds the B+ advantage
A C in AP does not overcome the grade difference
Note: bonus points vary by school district. Always check your school's specific policy. Some districts add only 0.5 for AP; a small number use a 6.0 scale for AP/IB courses.
High School GPA for College Admissions — What Colleges Look For
GPA is typically the single most important factor in college admissions decisions. Test scores, essays, recommendations, and extracurriculars are all important — but GPA is foundational. Understanding where your GPA positions you is the starting point for building a realistic college list.
| College Tier | Unweighted GPA | Weighted GPA | Typical AP/IB Courses | Context |
|---|---|---|---|---|
| Ivy League and MIT / Stanford | 3.9 – 4.0 | 4.5 – 5.0 | 8 – 12 | Top 1–5% of class typically |
| Top 25 Universities | 3.7 – 3.95 | 4.2 – 4.8 | 6 – 10 | Highly selective — test scores and rigor both matter |
| Top 50 Universities | 3.5 – 3.85 | 4.0 – 4.5 | 4 – 8 | Selective — strong GPA plus extracurriculars required |
| Strong State Schools | 3.3 – 3.7 | 3.7 – 4.3 | 2 – 6 | Competitive for flagship state universities |
| Average State Universities | 2.8 – 3.3 | 3.2 – 4.0 | 0 – 4 | Broadly accessible 4-year programs |
| Less Selective Colleges | 2.0 – 2.8 | Varies | 0 – 2 | Open or minimally selective admissions |
Colleges like UC Berkeley, University of Michigan, and the entire UC system explicitly recalculate GPA — stripping PE, health, and other non-core courses. Some schools cap weighted GPA bonus at a certain number of courses.
This is why your school-reported weighted GPA may differ from the GPA a college considers. The unweighted academic core GPA is generally the most reliable comparison.
A 3.7 unweighted GPA with 8 AP courses is viewed more favorably than a 3.9 unweighted GPA with no AP courses at selective colleges. Course rigor demonstrates the willingness to challenge oneself.

NCAA GPA Requirements — Eligibility for College Sports
NCAA GPA eligibility is one of the highest-stakes uses of high school GPA. Student athletes must meet minimum GPA thresholds in approved core courses to compete at the college level — and the GPA used is different from your overall high school GPA.
Min GPA: 2.3
16 core courses
SAT/ACT sliding scale applies
Min GPA: 2.2
16 core courses
SAT/ACT sliding scale applies
Min GPA: No NCAA minimum
Individual schools set requirements
No NCAA test score floor
NCAA eligibility uses core course GPA only — not your overall high school GPA. Core courses are NCAA-approved academic subjects: English, math (Algebra I or higher), natural science (with lab), social science, foreign language, comparative religion or philosophy.
PE, health, driver's education, and remedial courses do NOT count. If you have non-core courses dragging down your overall GPA but strong core course grades, your NCAA GPA may be higher than your overall GPA — or vice versa.
Action required: Student athletes must register with the NCAA Eligibility Center at eligibilitycenter.org to certify eligibility. This is separate from college admission and has its own deadlines.
How to Improve Your High School GPA — What the Numbers Require
GPA is most movable early and becomes progressively harder to change as you accumulate more credits. Use the GPA Predictor to run personalized calculations for your situation.
Every A in freshman year has maximum impact on long-term GPA. A 4.0 freshman year creates a strong foundation even if later years are slightly lower. A bad semester can still be fully recovered.
Still significant leverage — approximately 50–60% of total high school credits are still ahead. Course selection starts to matter: taking appropriately challenging courses (not overwhelming AP loads) produces better long-term GPA.
College applications typically reflect grades through junior year. Junior year grades carry the most weight in applications. GPA is becoming harder to move — check with our calculator if your target remains achievable.
Cumulative GPA is largely set by senior year. Focus on maintaining rather than dramatically improving. Senior year GPA still matters for final admission acceptance and scholarship retention.
An A in Honors (4.5 weighted) is better than an A in Regular (4.0 weighted) for the same effort level — if you can genuinely succeed at the Honors level, taking Honors courses improves your weighted GPA.
However, a B in AP (4.0 weighted) is equivalent to an A in Regular (4.0 weighted) on the weighted scale. AP is only worth taking for weighted GPA purposes if you can earn a B or better. If you earn a C in AP (3.0 weighted), you would have done better taking Regular.
Class Rank and High School GPA — How They Relate
Class rank situates your GPA within the context of your entire graduating class. Two students with identical GPAs may have very different class ranks depending on the competitiveness of their school.
A 3.8 GPA may be top 5% at a competitive school and top 20% at a less competitive school. Always check your school's specific rank data.
Many high schools have stopped reporting class rank to colleges to reduce unhealthy competition and because rank penalizes students at competitive schools. Yale, Stanford, and other elite schools historically considered rank, but today most rely primarily on transcript context.
Being in the top 10% of a large, competitive high school is more meaningful than top 10% of a small school. Admissions offices review school profiles to understand this context.
Valedictorian and Salutatorian are typically the rank 1 and rank 2 students. Many schools have moved to a Latin honors system for multiple top students rather than a single valedictorian.
