GPA frequently asked questions

The questions we are asked most often, answered directly

📅 Last updated: August 30, 2026

Short version: GPA is a credit-weighted average of grade points. Credits act as weights, failed courses count while pass/fail courses usually do not, and a cumulative GPA becomes progressively harder to move as credits accumulate. The answers below cover the questions that come up most often.

Calculation basics

Every GPA calculation is the same operation: quality points divided by credits, where quality points are grade points times credits for each course. Nothing else about the method varies between institutions — what varies is the scale used to turn a grade into grade points, and the rules for which courses are included. The step-by-step guide works through a full transcript, and cumulative GPA covers combining terms.

Scales and conversion

A grade of B is 3.0 on a 4.0 scale and 3.3 on a 4.3 scale — the same performance, a different number. Always report the scale with the figure. If you are converting from a percentage or from another country's system, convert course by course rather than converting a single overall average, and treat the result as an estimate. See the scale chart, percentage conversion and international conversion pages.

Failures, retakes and pass/fail

These three cases cause most of the confusion, and the rules are institutional rather than universal:

CaseUsual treatmentCheck with your school
Failed course (F)0 grade points, credits still countedWhether the F stays on record after a retake
Retaken courseVaries: replace, average, or count bothAlways — this determines whether a retake is worth it
Pass/failExcluded from GPAAny limit on how many you may take
Withdrawal (W)Excluded from GPAWithdrawal limits and financial aid effects
Transfer creditCredits transfer, grade points often do notRegistrar policy at the receiving school
Before any retake, get your school's repeat policy in writing. Under a replacement policy a retake delivers full benefit; under a count-both policy it can leave your GPA essentially unchanged.

Frequently asked questions

How is GPA calculated?

Multiply each course's grade points by its credits to get quality points, add the quality points up, then divide by total credits. Credits are the weights, which is why a 4-credit course affects your GPA twice as much as a 2-credit one.

What is the difference between GPA and average grade?

A percentage average works directly with your marks; a GPA first converts each mark to a point value on a fixed scale, then averages those. Because the conversion is banded, two students with different percentages can share the same GPA.

What is a good GPA?

3.0 is respectable, 3.5 is competitive, and 3.7 and above is strong. Past roughly 3.7 the marginal value drops sharply and reviewers start weighing research and experience more heavily.

Which GPA scale should I use?

The one your institution uses. The 4.0 scale is standard in the United States; 4.3, 4.5 and 5.0 scales are also in use elsewhere. Converting between them changes the number but not your standing, so always state the scale alongside the figure.

Do failed courses count towards GPA?

Normally yes — an F contributes 0 grade points while still adding its credits to the denominator, which is why a single failure is costly. Whether a retake replaces or merely supplements that grade depends on your school's repeat policy.

Do pass/fail courses affect my GPA?

Usually not. Pass/fail courses carry credits but no grade points, so they are excluded from the calculation entirely — they cannot lower your GPA, and they cannot raise it either.

Does this calculator store my grades?

No. Every calculation runs in your browser. Your draft entries are kept in your own browser's local storage so a refresh does not wipe them, and the 'clear' button deletes them. Nothing is sent to a server.

How do I convert a percentage to a GPA?

Map each course's percentage to grade points using your institution's published scale, then take the credit-weighted average. Converting your overall percentage average in one step gives a different — and less defensible — answer.

What is the difference between weighted and unweighted GPA?

An unweighted GPA caps every course at 4.0; a weighted GPA adds points for honours, AP or IB courses, so it can exceed 4.0. High schools mostly report weighted figures, universities mostly unweighted ones.

Can I calculate GPA for several semesters at once?

Yes. Enter every course from every term into the calculator as one list — that produces the correct cumulative figure. Do not average your semester GPAs together unless every term carried exactly the same number of credits.

Why did my GPA barely move after a good semester?

Because of inertia. With 30 credits behind you a perfect semester adds around 0.33 to your cumulative GPA; with 105 credits behind you it adds around 0.13. Early semesters carry disproportionate weight.

Is the calculator free?

Yes, with no registration and no limits. The site is currently ad-free.
