GPA Calculator for Law School — How LSAC Calculates Your GPA

When you apply to law school through LSAC (Law School Admission Council), LSAC recalculates your GPA from scratch using its own formula. Your LSAC GPA may be higher or lower than your official transcript GPA — and it is the LSAC GPA that law schools see, not your school's version. Understanding this calculation lets you know your actual competitive standing before submitting applications.

The free GPA calculator calculates standard weighted GPA using letter grades and credit hours — the same core math LSAC uses. This guide explains how LSAC's specific rules (including grade conversion and what courses count) affect the final number.

How LSAC Calculates Law School GPA — Key Differences from Your Transcript

LSAC calculates one GPA: a single cumulative GPA across all undergraduate coursework, using a specific grade conversion table. Key differences from most school transcripts:

1. LSAC includes ALL undergraduate work. Every undergraduate course from every school you attended — including junior college, community college, and any school you did not graduate from — is included. If your college uses grade forgiveness and lets you replace a D with an A on retakes, LSAC still includes the original D.

2. LSAC converts all grades to a universal 4.0 scale. Grades like "P" (Pass), "S" (Satisfactory), "CR" (Credit), and "NC" (No Credit) are typically excluded from the GPA calculation but may be reported. LSAC uses a specific grade conversion: A+=4.333, A=4.0, A-=3.667, B+=3.333, B=3.0, B-=2.667, C+=2.333, C=2.0, D=1.0, F=0.0 (and variations by school).

3. Grade replacement does not exist in LSAC. Both the original grade and the retake grade appear and are averaged. This is the most surprising rule — applicants who retook courses hoping to erase poor grades will find both grades in their LSAC GPA.

4. LSAC GPA is a weighted average. Like standard weighted GPA: sum of (grade points × credit hours) ÷ total credit hours. The free GPA calculator uses this exact formula — enter your letter grade and credit hours for each course to calculate your LSAC GPA estimate.

GPA Requirements at Top Law Schools (2026)

School	Median GPA (75th/25th percentile)	Median LSAT
Yale Law School	3.94 (3.98/3.87)	174
Harvard Law School	3.92 (3.97/3.82)	174
Stanford Law School	3.91 (3.97/3.80)	174
Columbia Law School	3.89 (3.95/3.78)	174
University of Chicago	3.89 (3.95/3.79)	174
NYU Law	3.86 (3.94/3.74)	173
Top 20 average	~3.75–3.88	168–172
Top 50 average	~3.60–3.75	162–168
Accredited ABA schools (lower tier)	~3.20–3.60	148–162

Law school admissions are heavily formulaic at most schools — the combination of LSAC GPA and LSAT score (sometimes called the "index score") determines admission outcomes more mechanically than medical school admissions. Soft factors (personal statement, recommendations, work experience) matter more at the margin, particularly near the median range of a school's class.

The LSAT can partially compensate for a lower GPA. A 175 LSAT with a 3.6 GPA may be competitive at top-14 schools; a 168 LSAT with a 3.95 GPA may not be enough for the top 3. Use law school admission calculators (like Law School Numbers or LSAC's own tool) alongside our GPA calculator to gauge your competitiveness.

How to Estimate Your LSAC GPA Using Our Calculator

Steps to estimate your LSAC GPA:

1. Gather ALL undergraduate transcripts. Every school you attended, even if for one semester. LSAC pulls all of them.
2. Include retaken courses twice. If you retook a course, add the original grade AND the retake grade — both count for LSAC purposes.
3. Exclude pass/fail courses. "P," "S," "CR" grades are typically not included in the GPA calculation (though they are reported). Leave these out of the calculator.
4. Enter each course, grade, and credit hours into the free GPA calculator. Use the letter grade closest to what you received. The calculator uses the standard 4.0 scale (A=4.0, A-=3.7, B+=3.3, etc.).
5. Note: LSAC uses A+=4.333 in some cases (school-dependent), while our calculator caps at 4.0. If your school awards A+ grades regularly, your actual LSAC GPA may be very slightly higher than our calculator shows.

The result is a close approximation of your LSAC GPA. The exact number will be confirmed when you create a CAS (Credential Assembly Service) account through LSAC — it is worth registering early to see your official LSAC GPA before finalizing your school list.

What To Do If Your GPA Is Below Law School Requirements

Score extremely high on the LSAT. The LSAT is a learnable test, and a 170+ score can offset a 3.4-3.5 GPA for many top-20 programs. Law school admissions is more forgiving of GPA-LSAT imbalances than medical school — if you demonstrate clear analytical ability through a high LSAT, many schools will look past a mediocre GPA.

Apply to schools where your GPA is above the median. Use the 25th percentile data to identify schools where your GPA is competitive. Applying to schools where you are above both medians gives you high admission probability. Aim for safety schools where you are above both medians, target schools at the medians, and reach schools below your GPA.

Master's degree or additional coursework. A strong master's GPA in a related field (public policy, political science, economics) can signal academic turnaround. However, LSAC does not include graduate-level coursework in the undergraduate GPA calculation — it is reported separately. Its impact is as a soft factor, not a direct GPA improvement.

Work experience. Significant legal work experience (paralegal, judicial clerkship, public defender office) or other meaningful professional experience can improve your application independently of GPA, especially at schools that emphasize practice-readiness over pure academics.

The upward trend argument. If your GPA improved significantly over four years — say, 2.9 freshman year and 3.8 senior year — write about it directly in your addendum. Admission officers understand that 18-year-olds make mistakes. A demonstrated upward trend with explanation is a real factor in borderline decisions.

Cumulative GPA vs Degree GPA — What LSAC Calculates

Your degree GPA (as calculated by your university) may only include courses taken at that institution. LSAC calculates a true cumulative GPA that includes every undergraduate credit hour from every institution you attended.

For most students who only attended one undergraduate school and did not take community college courses, these are the same. For students who transferred, took community college courses, or attended summer school at another institution, the LSAC GPA can differ from the degree GPA.

Transfer students in particular often find that their LSAC GPA is lower than their degree GPA — because LSAC includes the GPA from the school they transferred from, which is often why they transferred in the first place (after a rough start). This is a significant trap for law school applicants who transferred after struggling freshman or sophomore year.

Use the free GPA calculator to calculate cumulative GPA across multiple schools: just enter all courses from all institutions in one session. The cumulative GPA guide walks through doing this across multiple semesters and schools.

Frequently Asked Questions

Does LSAC include graduate school GPA?

No — LSAC's calculated GPA only includes undergraduate coursework. Graduate courses and grades are reported on the application but are not included in the LSAC cumulative GPA calculation.

What GPA is needed for Harvard Law?

Harvard Law's median GPA is approximately 3.92, with a 25th percentile of 3.82. A GPA below 3.7 is very difficult to overcome at Harvard, even with a perfect LSAT score. The 75th percentile is around 3.97.

Does LSAC count all colleges I attended?

Yes — LSAC requires transcripts from every undergraduate institution you attended, including community colleges, summer sessions at other schools, and schools you did not graduate from. All those credits and grades are included in the cumulative GPA.

Can I raise my LSAC GPA with a post-baccalaureate program?

No — LSAC only includes undergraduate coursework in its calculated GPA. Post-baccalaureate and graduate courses are reported separately and do not raise the LSAC cumulative GPA. However, they are a strong soft factor that admissions officers consider.
