Calculate LSAC GPA on the CAS 4.33 Scale

The LSAC GPA calculation runs on a 4.33 scale that the Credential Assembly Service applies to every applicant who attended a US or Canadian undergraduate institution. The single feature that separates this calculation from your school transcript is the treatment of A+ grades: LSAC awards 4.33 quality points per credit hour for an A+, while most US transcripts cap A+ at 4.00. If your school never issued an A+, your LSAC calculated GPA and your transcript GPA are identical. If you earned even a few A+ grades, the LSAC figure runs higher.

The remaining mechanics of the LSAC GPA calculation match what every credit-weighted GPA formula does: multiply each course\'s grade by its credit hours, sum the quality points, and divide by total graded credit hours. The calculator above runs that math live as you enter rows. For a deeper look at the underlying credit-weighted method shared with our cumulative GPA calculator, the math is the same; only the scale and the inclusion rules differ.

How does LSAC calculate GPA when grades repeat?

LSAC does not honor grade replacement, the policy at most US universities where a retake replaces the original grade. CAS counts every attempt. A student who earned a D in organic chemistry and retook the course for an A sees both grades in the LSAC calculation: the D contributes 1.00 times its credit hours to the numerator, and the A contributes 4.00 times its credit hours, with both sets of credits in the denominator. This is the single most common reason an applicant\'s LSAC GPA runs noticeably below the transcript figure. Use the calculator above and enter both attempts as separate rows to see your true LSAC number.

Calculate LSAC GPA across multiple institutions

The CAS report combines coursework from every institution you attended before your first bachelor\'s degree into a single LSAC calculated GPA. Community college dual enrollment grades earned in high school count. Summer-session classes at a second university count. Study abroad coursework counts when it appears on a US or Canadian transcript. Pre-baccalaureate post-bacc credits count. Once you finalize your first bachelor\'s degree, the GPA window closes; any later coursework appears in a separate section of the CAS report.

LSAC Calculate GPA Rules: What Counts and What Does Not

The LSAC calculate GPA methodology applies specific rules to non-standard grade entries, and the LSAC GPA calculator above lets you mark each row accordingly. The grade dropdown contains the standard 4.33-scale letter grades plus four special-status entries that LSAC handles differently.

Pass/Fail and Credit/No-Credit grades in LSAC GPA calculation

Pass grades (P), credit grades (CR), and satisfactory grades (S) are excluded from the LSAC GPA on both sides of the formula. They do not add quality points to the numerator and do not add credit hours to the denominator. A 15-credit semester with 12 graded credits and 3 pass/fail credits enters the LSAC math as 12 credits. The opposite case (failing grades in pass/fail courses) is handled differently: an F or NC outcome counts as 0.00 with the full credit-hour weight. The LSAC GPA calculator above maps the "P / CR / S" entry to exclusion automatically.

Withdrawals: punitive versus non-punitive in LSAC GPA

LSAC distinguishes between two categories of withdrawal. Non-punitive withdrawals (a plain W on the transcript) are excluded from the LSAC GPA calculation entirely. Punitive withdrawals (WF, WU, WNP) count as failures: 0.00 quality points with the full credit-hour weight in the denominator. This distinction matters when an applicant has multiple withdrawals from a single semester or a pattern of mid-semester drops. Mark each withdrawal row using the correct dropdown entry. WF and WU rows pull the LSAC GPA down sharply because they add zero to the numerator while contributing full credits to the denominator.

Audit, Incomplete, and remedial coursework

Audit grades (AU), Incomplete grades (I), non-credit courses, and remedial coursework below college level are all excluded from the LSAC GPA calculation. They appear on the CAS report for transparency but do not affect the GPA figure. The LSAC GPA calculator above includes an Audit / Incomplete entry in the dropdown for documentation purposes; selecting it records the row without contributing to the math.

LSAC CAS GPA calculator: how the official report shows your figure

The LSAC CAS GPA calculator output above mirrors what appears on the official CAS report. Once your transcripts are received and processed (typically 2 to 6 weeks depending on application season), CAS publishes a "Credential Assembly Service Report" inside your LSAC account. The report shows the LSAC-calculated cumulative GPA, the LSAC-calculated GPA by academic year, and the GPA percentile rank against all CAS applicants from prior cycles. Law schools see the same report. Run the calculator above to know your figure before the official report posts.

GPA Calculator LSAC Method: Step by Step

The GPA calculator LSAC method runs in four steps. First, collect every undergraduate transcript from every institution. Second, enter each graded course as a row with letter grade and credit hours. The calculator handles the 4.33 conversion automatically. Third, mark special-status entries (P / CR / S, W, WF, Audit) using the dedicated dropdown choices. Fourth, include every attempt of repeated courses. The 7sage LSAC GPA calculator and other third-party tools use the same underlying conversion table published by LSAC.

The result panel above shows three numbers at once. The LSAC GPA on the 4.33 scale is the figure law schools see. The 4.0 transcript equivalent shows what the same coursework would average on a standard transcript scale (no A+ bonus). The graded-credits total confirms how many credit hours actually counted toward the calculation, which helps you spot rows that were silently excluded for being pass/fail or non-punitive withdrawals.

LSAC Calculator GPA Output: How Law Schools Read the Number

The LSAC calculator GPA output pairs with the LSAT score in admissions index formulas at most ABA-accredited law schools. The 25th to 75th percentile GPA ranges published in each school\'s ABA 509 report use the LSAC calculated GPA, not the applicant\'s transcript GPA. A 3.70 LSAC GPA places an applicant in the T14 competitive zone; 3.50 to 3.69 opens the next tier of selective programs; 3.30 to 3.49 sits in the T50 range; and applicants below 3.30 typically pair with a high LSAT to qualify as splitters at competitive schools. Run the LSAC GPA calculator above before finalizing your application list to confirm where your figure lands.

LSAC GPA conversion calculator versus your transcript GPA

The LSAC GPA conversion calculator above reports the gap between your LSAC figure and your standard 4.0 transcript GPA in the result details. For an applicant with zero A+ grades the two numbers match exactly. For an applicant with several A+ grades, the LSAC figure can run 0.05 to 0.15 GPA points higher than the transcript. The 4.0 transcript equivalent panel makes the delta visible without requiring two separate calculator runs. Use it to confirm whether your A+ inflation is helping your LSAC application or whether the figures are essentially identical.

LSAC GPA Formula Reference

LSAC 4.33-Scale GPA Formula

LSAC GPA = Σ (Grade Points × Credit Hours) Σ (Graded Credit Hours)

Where:

Grade Points on the LSAC 4.33 scale: A+ = 4.33, A = 4.00, A- = 3.67, B+ = 3.33, B = 3.00, B- = 2.67, C+ = 2.33, C = 2.00, C- = 1.67, D+ = 1.33, D = 1.00, D- = 0.67, F = 0.00
Graded Credit Hours = credit hours from every row that contributes a grade. Pass / CR / S, plain W, Audit, and Incomplete are excluded.
WF, WU, WNP (punitive withdrawals) count as 0.00 with their credit hours.
Every attempt of repeated courses counts. Quarter credits convert at 2/3 to semester equivalent before entry.

Example: Three courses: A+ at 3 credits = 12.99 quality points, A at 4 credits = 16.00, B+ at 3 credits = 9.99. Total = 38.98 over 10 credits. LSAC GPA = 38.98 / 10 = 3.90.

LSAC Grade Calculator Edge Cases: Quarter Credits and Non-Standard Transcripts

The LSAC grade calculator above assumes a standard US semester-credit transcript. Two adjustments handle the common edge cases.

LSAC GPA calculator quarter system conversion

Quarter-system institutions issue credits at a 1.5x rate relative to semester systems. A 4-quarter-credit course covers roughly the same content as a 2.67-semester-credit course. Before entering quarter-system courses into the LSAC GPA calculator above, multiply each credit value by 2/3 (or 0.67). The University of California system (except UC Berkeley and UC Merced), Stanford, University of Washington, Dartmouth, Northwestern, and the University of Chicago all use the quarter system. The CAS report displays converted figures on the back end; the calculator above relies on you to convert at entry.

4.33 GPA calculator behavior for international transcripts

The 4.33 GPA calculator above does not handle international credential conversion. Applicants whose only undergraduate degree comes from a non-US, non-Canadian institution do not receive a CAS-calculated GPA in the normal sense; LSAC runs the Foreign Credential Evaluation Service instead, which produces an equivalency report rather than a single GPA figure. Applicants with mixed transcripts (some US coursework, some international) see the US portion calculated on the 4.33 scale and the international portion noted separately. Consult the LSAC International Applicant Guide before relying on a calculated figure.

Tips for Using the LSAC GPA Calculator Accurately

Gather every transcript first. Missing a single community college transcript from dual enrollment can shift the LSAC calculated GPA by 0.05 or more.
Enter every repeat attempt. LSAC does not honor grade forgiveness. Both attempts of a retaken course count in the numerator and the denominator.
Mark pass/fail rows correctly. The P / CR / S dropdown entry excludes the row from both sides of the calculation. Selecting a letter grade for a pass/fail course inflates the LSAC GPA artificially.
Distinguish W from WF. A plain W is non-punitive and excluded. A WF, WU, or WNP is punitive and counts as 0.00 with full credit-hour weight.
Convert quarter credits before entry. Multiply quarter credits by 2/3 to get the semester equivalent the LSAC formula expects.
Verify against the official CAS report. The calculator above matches the published methodology, but registrar-level transcript corrections submitted after CAS verification can shift the official figure.

Always confirm with the official CAS report before finalizing law school applications.

How does LSAC calculate GPA differently from your undergraduate transcript?

The Credential Assembly Service (CAS) recomputes your GPA on a 4.33 scale using every graded undergraduate course from every institution you attended. A+ counts as 4.33 rather than the 4.00 most US colleges award. Every attempt of a repeated course counts, so grade-replacement policies your school honors are ignored. Pass and credit grades (P, CR, S) are excluded entirely, while punitive withdrawals (WF, WU, WNP) and failing grades count as 0.00 with their credit hours. The result is the LSAC calculated GPA that appears on every CAS report law schools see.

How to calculate LSAC GPA before your CAS report arrives?

List every graded undergraduate course from every institution you attended, including community college dual enrollment, summer transfers, study abroad with graded credit, and pre-baccalaureate post-bacc work. Convert each letter grade to the LSAC 4.33 scale (A+ = 4.33, A = 4.00, A- = 3.67, B+ = 3.33, B = 3.00, and so on). Multiply each grade by its credit hours, sum the products, and divide by total graded credit hours. Include every attempt of repeated courses. The LSAC GPA calculator above runs the math automatically in under a minute.

How does the LSAC calculate GPA for pass/fail and credit/no-credit courses?

Pass, credit, and satisfactory grades (P, CR, S) are excluded from the LSAC GPA calculation entirely. They contribute no quality points to the numerator and no credit hours to the denominator. A semester with 12 graded credits and 3 pass/fail credits counts as 12 credits in LSAC math. Failing pass/fail outcomes are handled differently: an F or NC grade in a pass/fail course counts as 0.00 with its credit hours, which can pull your LSAC calculated GPA down. Mark pass/fail rows accordingly in the calculator above to reproduce CAS behavior.

How is LSAC GPA calculated when a course was repeated at the same school?

Every attempt counts. If you earned a D on the first attempt and an A on the retake, both grades and both credit-hour entries appear in the LSAC GPA calculation. This is the single biggest reason the LSAC calculated GPA runs lower than the transcript GPA for applicants whose schools honor grade replacement. Enter both attempts in the calculator above as separate rows to match the CAS methodology exactly. The numerator gets the sum of both quality-point contributions and the denominator gets both sets of credit hours.

How is AP credit calculated in LSAC GPA?

AP credit counts only if it appears on your undergraduate transcript with both a letter grade and credit hours. Most US universities post AP credit as pass / no-record or as advanced standing without a letter grade, and those entries are excluded from the LSAC GPA calculation. A few schools issue letter grades for AP credit, and those count normally on the 4.33 scale. Check how each AP entry is posted before adding it to the calculator above. CLEP credit follows the same rule: graded with credit hours counts; non-graded does not.

Does LSAC only calculate your undergrad GPA or do graduate credits count?

The primary LSAC calculated GPA (the number law schools see first) includes only undergraduate coursework completed through the date of your first bachelor's degree. Graduate coursework appears in a separate section on the CAS report but does not factor into the main GPA figure. Post-baccalaureate undergraduate work taken after the first bachelor's degree is also handled separately on the CAS report. Law schools see both numbers but evaluate them independently. Strong post-bacc or grad performance signals academic recovery but does not change the primary LSAC GPA.

How does LSAC calculate units GPA for quarter-system transcripts?

Quarter credits are converted to semester-credit equivalents before they enter the LSAC GPA calculation. The conversion is straightforward: multiply quarter credits by 2/3 (or 0.67) to get the semester equivalent. A 4-quarter-credit course becomes 2.67 semester credits in the LSAC formula. Convert each quarter-credit row before entering it in the LSAC GPA calculator above. Quarter-system institutions include most University of California campuses (except Berkeley and Merced), Stanford, and the University of Washington. The CAS report displays the converted figures.

How long does it take to calculate GPA in LSAC after transcripts arrive?

CAS transcript processing typically runs 2 weeks off-peak and 4 to 6 weeks during the October through January peak. The LSAC GPA calculation itself is near-instant once transcripts are processed; the wait is OCR processing, quality review, and human verification. Applicants targeting early-decision deadlines should submit transcripts 6 to 8 weeks before the deadline. The LSAC GPA calculator above gives you an instant preview so you can finalize your school list while CAS processing runs.

How accurate is the LSAC GPA calculator output versus the official CAS report?

For standard US 4-year undergraduate transcripts, calculator output matches the official CAS figure to within 0.01 GPA point. The calculator above applies the published 4.33-scale conversion, counts every attempt of repeated courses, and handles pass/fail and punitive-withdrawal rules per LSAC. Edge cases where the calculator may differ slightly: non-standard grading systems (narrative grades, competency-based transcripts), international credentials, internships posted with unusual grade types, and transcripts with mid-cycle registrar corrections. Always confirm against the official CAS report before relying on the figure for application decisions.

How does LSAC calculate GPA for international applicants and study abroad?

Study abroad courses count in the LSAC GPA only when they appear on a US or Canadian undergraduate transcript with a letter grade and credit hours. Direct-enrollment international courses that never transfer back to a US transcript are typically excluded. Foreign-credential applicants without a US or Canadian bachelor's degree do not receive a CAS-calculated GPA at all; instead, LSAC provides a separate Foreign Credential Evaluation Service. The LSAC GPA calculator above is built for the standard US transcript case. International applicants should consult the LSAC International Applicant Guide for non-standard credential handling.
