Law School Admissions — LSAC Credential Assembly
Law School GPA — LSAC formula,
all attempts, all schools.
LSAC doesn't care about your school's GPA. It builds its own — from every graded course you've ever taken as an undergrad, at every institution, with no grade replacement. Enter your courses below and see the number law schools actually receive.
How to use this calculator
Four steps to your
accurate LSAC GPA estimate
LSAC computes your GPA from scratch — it doesn't use the number on your diploma. To get an estimate that matches what law schools see in your CAS report, follow these four steps.
Include courses from every undergraduate institution
LSAC requires official transcripts from every undergraduate institution you attended — your four-year university, any community colleges, summer school at a different school, and study-abroad credits from US partner institutions. Every graded course from every school goes into one combined GPA calculation. This is different from how many schools report GPA (usually just their own coursework). Enter all courses regardless of where you took them to get an accurate estimate.
Enter both the original grade and any retake — separately
LSAC does not honor grade replacement policies. If your university replaced a C with an A when you retook a course, your school's transcript shows only the A — but LSAC's GPA calculation includes both. Add two separate rows: one for the C (original attempt) and one for the A (retake). Missing the original grade means overestimating your LSAC GPA. This is one of the most common reasons applicants are surprised when they see their actual CAS report.
Use standard letter grades — omit Pass/Fail courses
This calculator handles the standard A/B/C/D/F scale with plus/minus modifiers. Pass/Credit/Satisfactory courses typically do not contribute grade points to your LSAC GPA (though they appear on your CAS report). Do not enter P, CR, or S grades — they don't move your GPA numerically. Similarly, W (Withdrawal) has no grade points. If your institution awards A+ as a distinct grade above A, your real LSAC GPA may be marginally higher than this estimate at institutions where LSAC assigns 4.33 for A+.
Match your result against target school GPA/LSAT medians
LSAC GPA doesn't exist in isolation — law schools evaluate it alongside your LSAT score using an admissions index. Use your estimated LSAC GPA to identify schools where you fall in the 25th–75th percentile GPA range, then check whether your LSAT is in the same band. A GPA below a school's 25th percentile can be offset by an LSAT above their 75th percentile — the LSAC's own score band data shows which GPA/LSAT combinations tend to be competitive at which school tiers.
How LSAC computes your GPA
Not your school's GPA —
LSAC's standardized recalculation
When you register for LSAC's Credential Assembly Service (CAS), LSAC collects official transcripts from every undergraduate institution you attended. It then applies its own grade conversion to every course and calculates a single cumulative GPA that every law school receives. This standardized GPA is what appears on your CAS report — and it's the GPA number that counts in law school admissions, not the one on your diploma.
The formula is credit-weighted averaging — the same math your university uses, but applied uniformly across all institutions and without any grade replacement or forgiveness. Every graded course from every school goes into one pool:
The key rule: all attempts, all schools
Your school might offer grade replacement — let's say you earned a D in Accounting, retook it, earned an A, and your school's GPA shows only the A. LSAC sees both the D and the A. The D earns 1.0 grade points × its credit hours; the A earns 4.0 × its credit hours. Both go into the numerator and denominator. Your LSAC GPA reflects the real trajectory of your academic performance, not a cleaned-up version.
This catches many applicants off guard, especially those who relied on grade replacement to boost their undergraduate GPA. The gap between your school-reported GPA and your LSAC GPA can be significant if you've retaken several courses or transferred between institutions.
Worked example
Why your LSAC GPA can differ
from your school GPA
Here's a five-course example that shows the impact of a retaken course and a community college transfer, both of which your school may handle differently from LSAC.
| Course | Institution | Grade | Credits | Points |
|---|---|---|---|---|
| Microeconomics (original) | Comm. college | C (2.0) | 3 | 6.0 |
| Microeconomics (retake) | University | A (4.0) | 3 | 12.0 |
| Constitutional Law Survey | University | A− (3.7) | 3 | 11.1 |
| Statistics I | University | B+ (3.3) | 4 | 13.2 |
| Writing & Rhetoric | University | A (4.0) | 3 | 12.0 |
LSAC GPA: (6.0+12.0+11.1+13.2+12.0) ÷ (3+3+3+4+3) = 54.3 ÷ 16 = 3.39
If your university had replaced the community college C with the university A (as many schools do), your school-reported GPA would be higher. But LSAC counts both — the C from the community college and the A from the retake each contribute to the calculation. This is a 0.3+ GPA difference that surprises many applicants.
LSAC grade conversion
How LSAC converts
letter grades to points
LSAC uses a grade conversion table that maps your institution's grades to point values. For standard A/B/C/D/F grading with plus/minus, the table is essentially the standard 4.0 scale. LSAC may assign 4.33 for A+ at institutions that explicitly differentiate A+ from A on the grade scale, but most institutions map A+ = A = 4.0. Source: LSAC GPA Conversion.
| Letter grade | LSAC points | Notes |
|---|---|---|
| A+ / A | 4.0 (or 4.33*) | *4.33 if institution explicitly awards A+ above A |
| A− | 3.67 | Slightly below A — note minor difference from AMCAS (3.7) |
| B+ | 3.33 | |
| B | 3.0 | |
| B− | 2.67 | |
| C+ | 2.33 | |
| C | 2.0 | |
| C− | 1.67 | |
| D+ / D / D− | 1.33 / 1.0 / 0.67 | |
| F | 0.0 | Counts even if retaken and passed |
| W | — | Withdrawal — no grade points; doesn't affect GPA |
| P / CR | — | Pass/Credit — typically no grade points; excluded |
This calculator uses the standard 4.0-based values (A=4.0, A-=3.7, B+=3.3, etc.). If your institution awards A+=4.33, your real LSAC GPA may be marginally higher than this estimate.
Competitive benchmarks
What LSAC GPA looks like
at various law school tiers
LSAC publishes raw GPA and LSAT score data for every ABA-accredited law school through the Official Guide to ABA-Approved Law Schools. Here's a practical overview of GPA ranges by school tier, using the 25th–75th percentile data for recent entering classes. Source: LSAC ABA Data.
| School tier | 25th pct. GPA | 75th pct. GPA | Context |
|---|---|---|---|
| T3 (Yale, Harvard, Stanford) | 3.82 | 3.97 | Median LSAT 174+ |
| T6–T14 | 3.68 | 3.92 | Median LSAT 168–173 |
| T15–T50 | 3.40 | 3.78 | Median LSAT 158–168 |
| Regional schools (T51–T100) | 3.10 | 3.60 | Median LSAT 150–160 |
| Lower-ranked ABA schools | 2.80 | 3.40 | Median LSAT 143–152 |
These are approximations — individual schools vary, and data shifts slightly year to year. LSAT correlates strongly with school tier; a 170+ LSAT with a 3.5 GPA opens T14 doors that a 3.5 GPA alone wouldn't. Use LSAC's score band calculator and individual school profiles for precise targeting.
Strategy
What you can do if your
LSAC GPA isn't where you want it
Unlike MCAT, you can't retake the LSAC GPA calculation. But you can influence it — and you can also build a compelling application narrative around an imperfect GPA.
If you haven't graduated yet
Your LSAC GPA includes every course you've taken — including courses you'll take this semester. Every additional A you earn adds quality points to your numerator, and the denominator grows proportionally. If you're close to graduation with a 3.3 GPA and have one semester left, a 4.0 semester won't move your GPA dramatically — but it signals an upward trend that can be explained in your addendum.
Use this calculator to simulate: enter your current courses, then add hypothetical future courses with A grades to see how much your projected LSAC GPA moves. A 3.3 with 80 completed credits and one semester of As typically moves about 0.05–0.10 GPA points. Meaningful, but not transformative — which is why LSAT prep often gives a better return on time investment at this stage.
If you've already graduated
Post-bacc undergraduate coursework doesn't exist in law school admissions the way it does for medical school — law schools weight LSAT heavily enough that a high LSAT score is the more reliable lever for a graduated applicant. That said, a master's degree with a strong GPA (3.5+) can add positive context. Some applicants take relevant master's programs (public policy, economics, legal studies) both to strengthen their candidacy and to demonstrate academic capability.
The GPA addendum is also an underused tool. If your GPA dipped due to a specific, explainable circumstance (illness, family crisis, financial hardship) during a defined period, a brief, matter-of-fact addendum that explains what happened and what changed can help admissions committees contextualize your transcript. It doesn't raise your LSAC GPA — but it shapes how it's read.
Limitations
What this calculator can't do —
and what to watch for
This calculator gives you a close estimate of your LSAC GPA using the same formula and grade scale. Here's where it might differ from your actual CAS report:
- A+ grade handling. This calculator treats A+ as 4.0. If your institution's scale awards A+ = 4.33 (some do), your real LSAC GPA may be slightly higher, especially if you have many A+ grades.
- Non-letter grades. Pass/Fail, CR/NC, and satisfactory/unsatisfactory grades don't appear in this calculator. In LSAC, these typically don't affect your GPA (no grade points assigned), but they do appear on your CAS report and may be viewed by admissions committees.
- Foreign transcripts. LSAC handles grades from foreign institutions using its own conversion processes. This calculator only handles the standard US A–F system.
- Honor's marks and plus-letter variants. Grades like "High Pass" or "H" used by some institutions are handled individually by LSAC — they may or may not translate to 4.0. Check with LSAC if your transcript includes non-standard marks.
- Always verify in CAS. The authoritative LSAC GPA comes from the official CAS calculation after you've submitted all transcripts. Source: LSAC Credential Assembly Service.
Frequently asked questions
Law school GPA — what applicants ask most
I transferred between schools — do both transcripts count?
Yes, LSAC requires official transcripts from every undergraduate institution you attended. Every graded course from your first school and every graded course from your transfer school both go into the LSAC GPA calculation. This surprises many transfer students who assumed LSAC would only see their most recent institution's transcript. Even if your transfer school "accepted" your previous credits as equivalent, LSAC wants the original transcript with the original grades.
My school has a grade replacement policy. Will LSAC see the original grade?
Yes. LSAC does not honor grade replacement or academic forgiveness policies. If you retook a course and your school's GPA shows only the higher grade, LSAC still pulls both grades from your full transcript. The original grade and the retake grade both appear in your CAS report. This means your LSAC GPA can be noticeably lower than your school-reported GPA if you've retaken multiple courses.
Do summer courses count in my LSAC GPA?
Yes — any graded undergraduate course that appears on an official college transcript counts, including summer courses, January term (J-term) courses, and intersession courses. The institution (whether it's your home school or a different school where you took summer classes) must send an official transcript to LSAC directly. Summer courses are treated identically to regular-semester courses in the GPA calculation.
How long does LSAC CAS processing take?
Typically 2–4 weeks after LSAC receives all your transcripts, though it can be longer during peak application periods (September–December). You can check processing status in your LSAC account. Don't wait until you're ready to apply — open your CAS account early, request transcripts from all institutions, and give LSAC time to process. Most law school deadlines run from November through February, and many schools have rolling admissions.
Can I get into a T14 law school with a 3.5 GPA?
Yes — with a sufficiently strong LSAT. A 3.5 GPA with a 175 LSAT is competitive at several T14 schools, particularly those that value LSAT more heavily in their index. A 3.5 with a 165 LSAT would likely require you to target schools lower in the T14. LSAC's own data shows that LSAT scores above the 95th percentile (approximately 172+) open doors at nearly every school, even with a GPA below median. Use individual school profiles and their 25th/75th percentile data to calibrate realistically.
What if I have a 4.0 my last two years but a rough first two years?
LSAC's single cumulative GPA doesn't show the trend — but an addendum does. Many law schools explicitly invite applicants to explain GPA anomalies. A compelling narrative: "I struggled academically my first two years due to [specific circumstance], but after [change], I earned a 4.0 GPA over my final 60 credit hours, demonstrating that I can perform at the level required for law school." Keep it factual and brief — admissions readers appreciate directness. Your trend is visible on your transcript even if it's not in the summary GPA.
Does law school GPA affect my LSAC GPA?
No — LSAC's undergraduate GPA calculation doesn't include law school coursework. If you've attended law school before and are applying again (as a transfer student or reapplicant), law school grades appear separately. For standard JD applications, LSAC GPA refers exclusively to undergraduate work.
Should I write a GPA addendum?
Write an addendum if your GPA story has a clear, specific explanation — not to apologize for mediocre grades, but to contextualize a genuine anomaly. Good addendum scenarios: a medical emergency that affected one semester; a documented family crisis that required you to work full-time during your studies; a documented learning disability addressed later in your academic career. Bad addendum scenarios: "I didn't try hard enough freshman year," "I changed majors and struggled," or any explanation that sounds like excuses without context. One page maximum; past tense; end on what changed or what you learned.
Is it worth retaking a course to raise my LSAC GPA?
It depends on how much it'll move your GPA and what you're giving up. Use this calculator: enter all your current courses, then add the retake with an A grade, and see how much your GPA changes. If you have 80 credit hours and you retake a 3-credit course, the maximum possible GPA improvement from earning an A (replacing a C) is about 0.07 GPA points. That's usually not worth a semester of tuition and lost LSAT prep time. However, if you have fewer total credits (say, 40), the impact is larger — closer to 0.15 points — and might be meaningful for crossing a threshold at your target school.
Does LSAC see community college coursework?
Yes — and this is one of the most common gaps in applicants' transcript collection. LSAC requires transcripts from every institution where you received undergraduate credit, including community colleges. Even if you took just one course at a community college years ago, you must have that institution send an official transcript to LSAC. Omitting a transcript is discovered during CAS processing and can delay your application or, in the worst case, be treated as misrepresentation.
How does a gap year or time off affect my application?
A gap year itself doesn't affect your LSAC GPA — that's computed from your transcripts, not from time elapsed since graduation. What matters is what you did during the gap year. Work experience (especially policy, government, nonprofit, or legal environments) can significantly strengthen a law school application. Many law school applicants do take a gap year to gain experience and improve their LSAT score — the LSAC application cycle runs on a rolling basis, so timing is more about your LSAT readiness than your graduation date.
What's the difference between this calculator and LSAC's own GPA calculator?
LSAC provides a GPA calculator through its website and CAS portal once you have an account. That calculator uses your actual transcript data as entered in the system. This calculator lets you estimate your LSAC GPA before creating an account — useful for deciding whether to apply this cycle, which schools to target, or how retaking courses would affect your number. For your actual LSAC GPA, use the CAS. For planning: use this. Source: LSAC CAS.
Achievability scenarios
LSAC GPA reality —
how the numbers play out for law school
Three applicants, three different GPA situations, each showing how LSAC's all-attempts rule interacts with target school tiers and the LSAT trade-off that law school applicants — unlike medical school — can leverage aggressively.
Maya — LSAC 3.6 + LSAT 172 Opens T14 Doors
Maya's school GPA reads 3.72, but after LSAC counts her two community college courses from sophomore year (a B and a C+ she'd since retaken), her LSAC GPA lands at 3.61. That's below the T14 median of roughly 3.78 — but Maya spent eight months on focused LSAT prep and scored a 172, placing her near the 99th percentile.
LSAC GPA: 3.61 (CC courses + retakes both counted)
LSAT: 172 (≈99th percentile)
Target: T14 schools where 75th pct LSAT = 173
A 172 LSAT with a 3.61 LSAC GPA places Maya in the "splitter" category — above GPA median at some T14s and below it at others, but with an LSAT that compensates. Schools that weight LSAT heavily in their index (e.g., schools tracking US News LSAT percentile rankings) find a 172 genuinely compelling even when GPA is below their median. Maya applies broadly across T6–T14 and receives several offers.
Jordan — Community College Courses Drop LSAC Below Reported GPA
Jordan's university transcript shows a clean 3.70 GPA. But Jordan took 18 credits at a community college before transferring — a mix of Bs and one C — that the university accepted as transfer credit without displaying the original grades. Jordan's school GPA shows 3.70 because the university omitted those CC courses from its calculation.
CC courses: 18 credits, avg B− (2.67) = 48.06 pts
University courses: 90 credits, avg 3.76 = 338.4 pts
LSAC GPA: (48.06+338.4) ÷ 108 cr = 3.58
The 0.12-point gap between Jordan's reported and LSAC GPA means schools targeted based on a 3.70 are now targeting on a 3.58. At T14 schools where the 25th percentile GPA is 3.68, Jordan is now below the 25th percentile rather than comfortably above median. Recalibrating the school list — adding schools where 3.58 is at or above median — is the practical fix, alongside an LSAT score that can compensate.
Sam — Retakes Across 3 Courses Leave LSAC GPA Near 3.0
Sam struggled academically across freshman and sophomore years — Ds and Cs in four courses. Retook three of them and earned As. But under LSAC's all-attempts rule, the original Ds and Cs stay in the calculation, joined by the new As. Sam now has 6 extra credit rows that include both the failures and the recoveries.
Retake As (12 cr): avg 4.0 = 48.0 quality points
Remaining 60 cr at 3.4: 204.0 quality points
LSAC GPA: (18+48+204) ÷ 84 cr = 3.21
Sam's school-reported GPA (with three grade replacements) shows 3.52 — but the LSAC GPA is 3.21. That 0.31-point gap is enormous in law school admissions, shifting Sam from mid-tier T50 to borderline T100 territory. At this point, LSAC GPA is essentially fixed — the only realistic lever is LSAT. A score of 165+ can partially bridge the gap; without it, Sam's strongest application targets regional ABA schools where the median GPA is in the 3.0–3.3 range.
