GPA Calculator — Weighted & Unweighted (4.0 / 4.33) + Cumulative

Calculate unweighted & weighted GPA, cumulative GPA, and the grades you need to hit a target. Private by design—everything runs in your browser.

Switch anytime; current rows recalculate live.
Course rows can override this cap.

Non-GPA transcript entries such as P, NP, I, and W are available in letter mode and are excluded from GPA math. Schools vary on whether pass/fail credits count toward earned credits.

How this calculator works

GPA is total quality points divided by GPA-bearing credits. Each course grade is converted to grade points, multiplied by credits, and then added to the total. Prior cumulative GPA is handled the same way: prior GPA x prior credits becomes prior quality points.

EnglishA34.012.0
BiologyB+43.313.2
History HonorsA- +0.5 weight34.212.6
ArtP1ExcludedExcluded
Totals10 GPA credits37.8 quality points

Final GPA in the example is 37.8 / 10 = 3.78. The pass grade is listed for the report but excluded from GPA math because many schools do not assign grade points to pass/fail courses.

Weighted policies: this calculator uses editable course presets: Regular +0.0, Honors +0.5, AP +1.0, IB +1.0, and College/Dual Enrollment +1.0. Many schools use +0.5 or +1.0 bumps, 4.5 or 5.0 caps, or local rules that cap only certain course types.

Note: Schools vary. Always follow your institution's official grade scale, retake policy, withdrawal policy, and weighting rules.

What your GPA means

General guidance only; admissions, scholarships, and academic standing depend on school and program context.

3.7-4.0Very strong performance on a 4.0 scale; often competitive for selective programs.
3.3-3.6Strong academic record with mostly A and B grades.
3.0-3.2Solid standing at many schools, often near a B average.
2.5-2.9Mixed record; may need improvement for competitive pathways.
Below 2.5Review academic standing rules and consider support options if available.

GPA calculator FAQ

What is the difference between semester GPA and cumulative GPA?

Semester GPA uses only the courses in one term. Cumulative GPA combines prior GPA-bearing credits with the current semester or multiple semesters.

What is weighted vs unweighted GPA?

Unweighted GPA uses the base grade points. Weighted GPA adds bonus points for courses such as Honors, AP, IB, or dual enrollment, usually subject to a cap.

Why do credit hours matter?

Credits control how much each class affects the average. A four-credit class contributes four times as many quality points as a one-credit class with the same grade.

What are quality points?

Quality points are grade points multiplied by credits. GPA is total quality points divided by total GPA credits.

Is a 3.5 GPA good?

Generally, a 3.5 is a strong GPA, but the answer depends on grade scale, course rigor, school context, and the goal you are comparing against.

Do pass/fail grades affect GPA?

Usually P, NP, S, U, I, and W do not carry grade points and are excluded from GPA calculations. Your transcript may still count attempted or earned credits differently.

Do withdrawals affect GPA?

A W is usually excluded from GPA, but withdrawals can still affect progress, financial aid, or repeated-course limits.

How are retaken courses handled?

Retake rules vary. Some schools replace the old grade, some average both attempts, and some keep both on the transcript.

How should GPA be rounded?

Most reports round to two or three decimals. This calculator displays two decimals in the summary and keeps more precision internally during calculations.

Should A+ be 4.0 or 4.33?

Some schools cap A+ at 4.0, while others use 4.33. Choose the base scale that matches your school's policy.

Do AP and Honors weights count for college applications?

Sometimes. Colleges may recalculate GPA using their own methods, so your school-weighted GPA and an admissions recalculation can differ.

5 Fun Facts about GPAs

Weighted caps are local lore

Plenty of districts cap weighted GPAs at 5.0, but a few IB schools quietly allow 6.0+ for extended essays and HL courses.

Policy quirks

A+ isn’t universal

Some colleges ignore A+ entirely (treating it as 4.0), while others use 4.33—so the same transcript can shift a class rank overnight.

Scale surprises

Credit hours are leverage

A single 4-credit course can outweigh three 1-credit electives. Loading heavier credits with strong grades moves a cumulative GPA much faster.

GPA physics

Repeat rules vary wildly

Some schools replace the old grade; others average both attempts. A “retake boost” at one campus can barely budge GPA at another.

Retake reality

Pass/Fail still matters

Pass grades are usually excluded from GPA points, but schools may still count them toward earned credits, progress rules, or graduation requirements.
