How is GPA calculated?

Each letter grade maps to grade points — A is 4.0, B is 3.0, C is 2.0, D is 1.0, F is 0.0, with +/− variations in between. Multiply each course's grade points by its credit hours to get quality points, sum them across all courses, and divide by the total credit hours attempted. The result is the GPA for that term.

On the 4.0 scale: 3.7–4.0 is summa cum laude (A average), 3.5–3.69 is magna cum laude, 3.3–3.49 is cum laude, 3.0–3.29 is good standing. Most graduate programs require 3.0+; medical and law schools typically require 3.5+.

What is the difference between weighted and unweighted GPA?

An unweighted GPA caps at 4.0 and treats every course equally regardless of difficulty. A weighted GPA adds bonus points for harder courses — typically +0.5 for Honors and +1.0 for AP or IB — so it can exceed 4.0. Weighted GPA rewards taking a more rigorous course load and is often reported alongside the unweighted GPA for college admissions.

What is the difference between semester and cumulative GPA?

Semester (or term) GPA is calculated from courses completed in one academic period and is used for dean's list recognition and academic standing reviews. Cumulative GPA aggregates all completed semesters — it is the number printed on official transcripts, reported to employers, used in graduate school applications, and determines academic honors at graduation (summa cum laude, magna cum laude, cum laude).

How do I convert percentage grades to GPA?

The most common US conversion: 90–100% = A = 4.0, 80–89% = B = 3.0, 70–79% = C = 2.0, 60–69% = D = 1.0, below 60% = F = 0.0. Many institutions use plus/minus grades: A− = 3.7, B+ = 3.3, B− = 2.7. UK and Indian universities use different systems — UK First requires 70%+, UK 2:1 requires 60–69%. Always verify your specific institution's official grade conversion table.

Does a failing grade affect GPA permanently?

Yes, unless your institution allows grade replacement or academic forgiveness. An F (0 grade points) weighted by credit hours pulls down the cumulative GPA significantly. Retaking and passing the course helps if your institution uses grade replacement policy.

Is my data sent to a server?

No. The GPA calculation runs entirely in your browser with JavaScript. No grades or course data are uploaded, logged, or stored anywhere. You can enter sensitive academic records without any privacy concern.

Free GPA Calculator — Calculate Grade Point Average Online

A GPA (Grade Point Average) is a numerical representation of academic performance calculated by multiplying each course grade point by its credit hours, summing the results, and dividing by total credit hours. This calculator supports the 4.0 scale (A=4, B=3, C=2, D=1, F=0) and custom percentage-to-grade conversions.

Dividing quality points by number of courses instead of credit hoursGPA = total quality points ÷ 5 courses

GPA is always weighted by credit hours, not course count. Divide total quality points by total credit hours attempted. A 3-credit A and a 1-credit A contribute differently — the 3-credit course has 3× the weight.

Using unweighted grade points for AP or Honors coursesAP Chemistry A = 4.0 in unweighted mode

For weighted GPA, an A in an AP course earns 5.0 (+1.0 bonus) and an A in a Honors course earns 4.5 (+0.5 bonus). Switch to weighted mode if your school calculates a weighted GPA.

Including non-credit courses in the GPA calculationAdding PE or audit courses at 0 credits

Non-credit courses and audited courses carry 0 credit hours and do not contribute to GPA. Including them as 0-credit rows inflates the denominator and lowers the GPA slightly. Only include courses with assigned credit hours.

Using percentage score directly instead of converting to grade pointsGrade = 88%, entered as 88 instead of B+ (3.3)

Convert percentages to letter grades first using your institution's scale, then map to grade points (B+ = 3.3, not 88). Entering raw percentages instead of grade points produces a wildly incorrect GPA.

Confusing semester GPA with cumulative GPA when calculating cumulativeCumulative = average of term GPAs

Averaging term GPAs ignores credit-hour weighting. A 12-credit semester and a 6-credit semester have different weights. Use the cumulative mode: enter prior cumulative GPA + prior credit hours, and this term's courses. The tool weights them correctly.

Forgetting that a failing grade still counts as credit hours attemptedRemoving the F course from the list to avoid lowering GPA

An F earns 0 grade points but the credit hours still go into the denominator — leaving it out overstates the GPA. Enter the F and its full credit hours. If your school allows grade replacement, contact the registrar instead of manually omitting it.

FAQ

Frequently asked questions

GPA (Grade Point Average) is a standardized measure of academic performance on a numeric scale, most commonly 0.0–4.0. It is calculated as the sum of (grade points × credit hours) for all courses divided by total credit hours attempted.
