What Is the LSAC GPA Calculator?
The LSAC GPA calculator converts the letter grades and credit hours on your undergraduate transcripts into the GPA that the Law School Admission Council reports to every law school you apply to. It applies LSAC's single official grade-quality-point scale to every institution you attended, so the number you see is the same one admissions committees receive on your CAS report.
- • Pre-application check: Estimate your CAS GPA before submitting transcripts so there are no surprises in the report.
- • Compare schools: See how the same grades read under LSAC's fixed scale versus your registrar's running average.
- • Plan a retake: Model whether repeating a course meaningfully moves the LSAC average given that both attempts count.
- • Explain a gap: Show why your CAS GPA differs from your school GPA when plus/minus weighting or repeats are involved.
Most schools print their own GPA using local rules for plus and minus grades, repeats, and pass/fail marking. LSAC ignores those local rules and recalculates everything on one standard table, which is why applicants often see a different figure than the one on their diploma.
This tool focuses on that recalculation. Enter your graded courses with their credit hours, and it returns the LSAC GPA, the total quality points, and the total graded credits that produce it.
If you are also applying to medical school, the AMCAS GPA calculator applies a different single 4.0 scale to the same transcripts.
How the LSAC GPA Calculator Works
The LSAC GPA calculator multiplies each course's credit hours by the LSAC quality point for its letter grade, sums those products across all graded courses, then divides by the total graded credit hours. Courses with no letter grade, such as withdrawals or pass/fail marks, contribute nothing to either total.
- quality points: The LSAC value for a grade: A+ 4.33, A 4.0, A- 3.67, B+ 3.33, B 3.0, B- 2.67, C+ 2.33, C 2.0, C- 1.67, D+ 1.33, D 1.0, D- 0.67, F 0.0.
- credit hours: The semester or quarter hours assigned to the course; only courses with credit hours greater than zero count.
Because LSAC uses a 4.33 top of scale, an A+ contributes more than a straight 4.0 and can lift the cumulative figure above 4.0. That is expected on the LSAC scale and is not an error in the report.
Three courses across credit weights
A in a 3-credit course, B+ in a 3-credit course, and A- in a 4-credit course.
(4.0 x 3) + (3.33 x 3) + (3.67 x 4) = 12.00 + 9.99 + 14.68 = 36.67 quality points over 10 credits.
36.67 / 10 = 3.667, which rounds to 3.67.
The 4-credit A- pulls more weight than the two 3-credit courses, which is why weighting by credit hours matters.
According to LSAC - How LSAC Calculates Your GPA, LSAC converts each undergraduate letter grade to a standard quality point and weights it by credit hours to produce the CAS GPA.
Because the LSAC result sits on a 4.33 scale, the GPA to percentage converter translates it into the percentage bands some programs request.
Key Concepts Explained
Four ideas explain most of the gap between your transcript GPA and the LSAC number.
The 4.33 scale
LSAC assigns A+ a value of 4.33, so the scale reaches above 4.0. This is the main reason an LSAC GPA can exceed the 4.0 your school reports.
Quality points
Each letter grade maps to a fixed quality point that LSAC applies to every school's transcript, removing differences in how institutions weight plus and minus grades.
Credit-hour weighting
A 4-credit course moves the average roughly twice as far as a 2-credit course, so heavier classes deserve the most attention when planning retakes.
Excluded grades
Withdrawals, pass/fail, satisfactory/unsatisfactory, audit, and credit/no-credit grades appear on the CAS report but carry no quality points and stay out of the GPA.
Knowing these four concepts makes the result predictable: you can see in advance which courses will matter most and which marks will be ignored entirely.
Your registrar's running average from the college GPA calculator may weight plus and minus grades differently than LSAC does.
How to Use This Calculator
Enter up to six courses to project your LSAC GPA before you send transcripts to the CAS.
- 1 List your courses: Pull the graded undergraduate courses you most want to understand from your transcript.
- 2 Enter grade and credits: Pick the letter grade and type the credit hours for each course; set credits to 0 for any row you are not using.
- 3 Mark excluded marks: Use W, P, S, or U for withdrawals and pass/fail entries so they are listed but kept out of the GPA.
- 4 Read the three outputs: The LSAC GPA is the headline figure; total quality points and total graded credits show how it was built.
- 5 Adjust and recheck: Change a grade or credit value to see how a retake or a new course would shift the cumulative number.
A student with a 3-credit A, a 3-credit B+, and a 4-credit A- can type those rows and immediately see a 3.67 LSAC GPA built from 36.67 quality points over 10 credits, which is useful when weighing an extra course against retaking a weaker one.
To roll several terms into the all-semester figure LSAC ultimately reads, the cumulative GPA calculator builds the combined total.
Benefits of Using This Calculator
A generic GPA tool cannot reproduce the LSAC number because most schools weight plus and minus grades and many drop retaken courses. This calculator exists for that gap.
- • Matches the LSAC scale: It applies the exact 4.33 quality-point table to every course, mirroring how the CAS report is actually built.
- • Handles excluded marks: Withdrawals and pass/fail entries are listed but kept out of the GPA, so the projection matches the CAS treatment.
- • Shows the build: Total quality points and total credits make the average transparent instead of presenting a single unexplained number.
- • Supports retake planning: Because LSAC counts both attempts of a repeat, you can see how much a retake really moves the average.
The transparency matters most when your transcript and CAS figures disagree, because you can point to the exact courses and rules that explain the difference. The LSAC GPA calculator makes that comparison visible instead of leaving the gap unexplained.
When you want to isolate one upcoming term before it joins the CAS record, the semester GPA calculator keeps the projection to a single semester.
Factors That Affect Your Results
Three things change the LSAC number more than applicants expect, and the calculator surfaces each one the moment you adjust a row.
Credit-hour weighting
Heavier courses drag or lift the average far more than light ones, so plan retakes and new courses with their weights in mind.
Plus and minus weighting
LSAC's fixed scale can differ from your school's, which is the most common source of a gap between the two GPAs.
Repeated coursework
LSAC keeps both attempts, so a repeat improves the average only partway and never erases the original grade.
- • The calculator estimates the LSAC result from the rows you enter; it does not read your official transcript, so the projection covers only the courses you list.
- • LSAC applies additional transcript rules, such as how study-abroad and postbac work is folded in, that this six-row tool cannot reproduce in full.
A concrete example shows the math: repeating a 4-credit course that earned a B (3.0) as an A (4.0) adds 4.0 quality points across those credits, but the original B still counts, so the average rises by less than a full grade point rather than resetting to 4.0. The LSAC GPA calculator keeps both attempts in view, which is why a retake shifts the cumulative figure only partway.
According to LSAC - How LSAC Calculates Your GPA, Pass/fail, withdrawal, and satisfactory/unsatisfactory grades appear on the CAS report but are excluded from the GPA calculation.
Applicants to osteopathic programs should also check the AACOMAS GPA calculator, because that service folds science and non-science grades together on its own scale.
Frequently Asked Questions
Q: How does LSAC calculate GPA from my transcript?
A: LSAC reads every graded undergraduate course from every institution you attended, converts each letter grade to its standard quality point (for example A = 4.0, B+ = 3.33), multiplies that by the course's credit hours, adds all those products, then divides by the total graded credit hours. The result is the GPA that appears on your CAS report.
Q: What grade point does LSAC assign to an A+?
A: LSAC assigns 4.33 to an A+, so the LSAC scale runs to 4.33 rather than topping out at 4.0. That differs from services such as AMCAS, which treat A+ and A the same at 4.0, and from schools that cap the scale at 4.0.
Q: Does LSAC include pass/fail and withdrawn courses in my GPA?
A: No. Courses marked pass/fail, withdrawal (W), satisfactory/unsatisfactory, audit, or credit/no-credit are listed on the CAS report but carry no quality points and are excluded from the GPA. Only letter-graded courses with credit hours count toward the average.
Q: Why is my LSAC GPA different from my school GPA?
A: Two reasons are common. First, LSAC uses one fixed scale for every school, so if your registrar weights plus and minus grades differently, the numbers diverge. Second, LSAC counts every attempt of a repeated course, while many schools replace the old grade, which can lower or raise the LSAC figure relative to your transcript.
Q: How does LSAC treat repeated courses?
A: LSAC includes both the original attempt and the retake in the GPA rather than replacing the first grade. A repeat therefore improves the average only partway, because the prior lower grade still counts in both the quality points and the credit-hour totals.
Q: Is the LSAC GPA on a 4.0 or 4.33 scale?
A: LSAC reports on a 4.33 scale, with A+ worth 4.33. The headline CAS GPA can therefore exceed 4.0 when you earn A+ grades, which is normal on the LSAC scale and should not be read as an error.
