GPA Calculator

Convert each course's letter grade to points on the 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiply each grade's points by that course's credit hours to get quality points, add up every course's quality points, then divide by the total credit hours across all courses. A 3-credit A and a 4-credit B produce 12 and 12 quality points; across 7 total credits, that's 24 ÷ 7 ≈ 3.43.

A semester GPA only includes courses from one term, while a cumulative GPA folds in every term completed so far, weighted by each term's credit hours. This calculator computes a semester GPA by default; entering a prior GPA and prior credit hours in the optional fields converts the result into a cumulative GPA that combines your transcript history with the current term's courses using the same credit-weighted formula.

Because GPA weights each grade by credit hours, not by course count. A 4-credit B contributes the same total quality points (12) as a 3-credit A, since 4 × 3.0 and 3 × 4.0 are both 12, even though a plain average would treat the A and the B as pulling equally. Two students with identical letter grades but different credit-hour loads can end up with different GPAs, which is expected and correct under the standard formula.

LSAC recalculates every undergraduate transcript under its own published Credential Assembly Service rules, which commonly differ from a school's own policy. The biggest driver is repeated courses: many schools let a retaken course's new grade replace the old one, while LSAC counts every attempt, original grade included, permanently. LSAC also combines every undergraduate institution attended into one recalculated figure, so its number is rarely identical to any single school's transcript GPA.

No, it uses the plain five-letter scale (A, B, C, D, F) at 4.0, 3.0, 2.0, 1.0, and 0.0, since that's the most commonly published default version of the 4.0 scale. Many schools do grade with plus/minus subdivisions instead, typically adding or subtracting about 0.3 per step (A- = 3.7, B+ = 3.3, and so on); the guide above includes the full reference table for schools that use it.

Enter your current cumulative GPA and total credit hours completed so far into the "prior GPA" and "prior credit hours" fields, then enter this term's courses normally. The calculator multiplies your prior GPA by your prior credit hours to recover your existing quality points, adds this term's quality points on top, and divides by the combined credit hours, the same formula transcripts use to update a running cumulative GPA.

It depends on the school. Many institutions exclude pass/fail courses from the GPA calculation entirely, since a Pass grade has no standard point value on the 4.0 scale, while the credit hours may still count toward the degree. This calculator only accepts letter grades A through F, so a genuinely pass/fail course shouldn't be entered into it at all; check your registrar's policy for how P/F coursework is actually handled.

Individual schools make policy choices a general-purpose calculator can't know in advance: some exclude pass/fail courses, cap how many repeat attempts replace an earlier grade, exclude transfer credit from the in-house GPA, or add extra weight for honors and AP courses. This calculator applies the standard unweighted formula; your school's registrar page or course catalog is the authoritative source for any of these school-specific adjustments.

There's no single cutoff; competitive programs vary widely by field and by school, and admissions committees also weigh test scores, coursework rigor, and other factors alongside GPA. Rather than relying on a general benchmark, check the specific program's published admitted-student GPA range, and for law school specifically, remember your recalculated LSAC GPA, not your raw transcript GPA, is the figure most law schools actually evaluate.

No, this is an unweighted GPA calculator, using the plain 4.0-point scale where an A is worth 4.0 no matter what class it's in. A weighted GPA, common on high school transcripts, adds extra points, often pushing an A in an honors or AP class above 4.0, to reflect that the course was harder. If your high school reports a weighted GPA, expect this calculator's unweighted result to read lower than your transcript for any schedule that includes honors or AP courses.

There's no single universal formula, since GPA conversion tables vary by school, but the most common convention treats 90-100% as an A (4.0), 80-89% as a B (3.0), 70-79% as a C (2.0), 60-69% as a D (1.0), and below 60% as an F (0.0). First convert your percentage grade to a letter grade using your school's official scale, then enter that letter grade into this calculator; it already applies the credit-weighted formula from there. Check your syllabus if you need the exact percentage cutoffs your school uses.

This calculator computes your GPA from grades already earned, not the reverse, but you can solve for it with the same formula: required GPA on remaining credits = (target GPA × total credits after those courses − current GPA × current credits) ÷ remaining credits. For example, a 3.0 GPA over 60 credits aiming for a 3.3 cumulative GPA across 90 total credits needs (3.3 × 90 − 3.0 × 60) ÷ 30 ≈ 3.9 on the next 30 credits. Plug in your own numbers the same way to see whether a target is realistic.

The calculator requires at least one course, or the prior-credits field, to carry more than zero credit hours, since dividing total quality points by zero total credit hours has no valid result. If you're only entering a subset of your courses, leave any unused course rows at zero credits, which contributes nothing to either the quality-points total or the credit-hours total and is safely ignored.
