LSAC GPA Calculator

Introduction

Law schools do not use the GPA printed on your transcript. They use the GPA that LSAC figures out for you. This LSAC GPA Calculator shows you that number before you apply.

LSAC follows its own set of rules. It adds up every undergraduate transcript you have.¹ It counts every try at a course, even if you took the class twice.¹ It gives A+ grades a value of 4.33.¹ It counts failing marks, such as an F or an Incomplete that signifies failure, as 0.00, and a "withdraw failing" too unless your school treats it as nonpunitive.¹ It leaves out AP credits, plain pass/fail passes, and anything you earned after your first bachelor's degree.¹ Those rules can push your LSAC CAS GPA above or below the GPA your school gave you.

To use the calculator, pick one of two ways to enter your grades. In Course-by-Course mode, you type each class, its grade, and its credit hours. In Aggregate by Grade mode, you type total credit hours next to each grade, using letters, percent ranges, or a 1-to-5 scale. You can add up to 10 schools and mark any transcript as post-graduation credits.

You get your estimated CAS GPA right away, plus total credit hours, total quality points, excluded credits, and a GPA for each school. A step-by-step section shows the math, and two charts show how your grades and your schools add up. Your verified LSAC GPA may differ by a small amount, but this puts you close to the real number.¹

How to use our LSAC GPA Calculator

Enter your college grades and credit hours from each transcript, and this calculator shows your estimated LSAC CAS GPA, your total credit hours, your total quality points, and a step-by-step breakdown of the math.

Entry Mode: Pick "Course-by-Course" to type in each class one at a time. Pick "Aggregate by Grade" to type total credit hours for each grade at once. Switching modes clears your data.

Institution name: Type the name of the school. This is just a label and does not change your GPA.

Mark as post-graduation credits: Turn this on if you earned these credits after your first bachelor's degree. LSAC does not count them, so they will be left out.

Course name: Type the class name, like "Calculus I". This is optional and only helps you keep track.

Grade: Choose the grade you earned from the list. Each grade has its LSAC point value next to it. Pick W, P, or AP/Transfer for credits LSAC leaves out.

Credit hours: Type how many credit hours the class was worth, like 3 or 4. Use 0 or more. Trimester hours are treated as semester hours, and quarter hours are multiplied by .67 to arrive at semester hours, so convert quarter hours before you enter them.¹

Add Course: Click this to add another class row. Enter each retake as its own row, since LSAC counts every attempt.

Credit hours by grade (Aggregate mode): Type your total credit hours next to each letter grade, percentage range, or 1-to-5 value. On a 1-to-5 transcript, 1 is the highest grade and 5 is a failure.¹ You can mix all three columns.

Excluded credit categories (Aggregate mode): Type credit hours for W grades, Pass grades, and AP, transfer, or dual enrollment work. These are tracked but never counted in your GPA.

Add Another School / Transcript: Click this to add a new transcript group. LSAC adds up every undergraduate school, so include all of them, up to 10.

What Is the LSAC GPA?

The LSAC GPA is the grade point average that law schools actually see. When you apply to law school, you send all your college transcripts to the Law School Admission Council (LSAC). LSAC uses its Credential Assembly Service (CAS) to recalculate every grade you ever earned as an undergraduate. The result is called your CAS GPA, and it can be higher or lower than the GPA on your own transcript.

Why Your CAS GPA Is Different

Your school has its own grading rules. LSAC has one set of rules for everyone, so all applicants are compared fairly.¹ Here are the biggest differences:

• Every attempt counts. If you retook a class, both grades count.¹ LSAC does not replace a bad grade with a better one.
• A+ is worth 4.33. Many schools cap grades at 4.0, but LSAC gives extra credit for an A+.¹ That means a CAS GPA can go above 4.0.
• Failing marks stay in. An F, an Incomplete that signifies failure, or a failed pass/fail class counts as 0.00 points, and the credit hours still count in the total.¹ A WF (withdraw failing) counts the same way unless your school treats it as nonpunitive.¹
• All schools are combined. Grades from every college you attended are added into one GPA, not just your last school.¹

The LSAC Grade Scale

LSAC turns each letter grade into points on this scale:

• A+ = 4.33, A = 4.00, A− = 3.67¹
• B+ = 3.33, B = 3.00, B− = 2.67¹
• C+ = 2.33, C = 2.00, C− = 1.67¹
• D+ = 1.33, D = 1.00, D− = 0.67¹
• F = 0.00¹

To get the GPA, you multiply each grade's points by its credit hours. That gives you quality points. Then you add up all the quality points and divide by all the credit hours.

Grades and Credits That Do Not Count

Some credits are left out of the CAS GPA completely. They are removed from both the points and the credit hours:

• W (a withdrawal with no penalty)¹
• P (a pass in a pass/fail class)¹
• AP credits (college credit from AP courses or tests).¹ Dual-enrollment and other college courses taken in high school count in the 2026–2027 application cycle and are left out starting with the 2027–2028 cycle.¹
• Post-graduation credits (anything you took after your first bachelor's degree was awarded, including graduate school)¹

Why Your CAS GPA Matters

Your undergraduate GPA and your LSAT score are the most predictive of success in law school and are fundamental to admission decisions.² Schools also report these numbers in rankings, so admissions offices watch them closely. Knowing your CAS GPA early helps you pick target schools, plan your last semesters, and set a realistic LSAT goal.

Keep in Mind

An estimate is not the official number. LSAC may convert your school's grading system differently than its standard table, so your verified GPA may be a little different.¹ Some marks, like a school's own "grade forgiveness" policy or unusual grade symbols, are handled by LSAC's own conversion tables. Always check your official CAS report once your transcripts are processed.
