Formula

Weighted GPA

GPA = sum(grade points x credits) / total credits

Each course grade is converted into grade points, multiplied by its credit hours, and averaged across the total credit load.

Step by step

How the calculation works

1Select the grade earned in each course.
2Enter the credits for each course.
3Multiply each grade point value by course credits.
4Divide total quality points by total credits.

Example

Example GPA result

A mix of A, B, A, and C grades across 12 credits produces a GPA slightly above 3.3.

Understanding Grade Point Average (GPA)

Grade Point Average (GPA) is a standard indicator of academic performance, representing the average value of accumulated final grades. To account for varying course workloads, GPA is calculated as a credit-weighted average rather than a simple mean.

Each letter grade is converted to a numeric value on the standard 4.0 scale (A=4, B=3, C=2, D=1, F=0). This grade value is multiplied by the course credit hours to determine the Quality Points for that course. The total quality points are then divided by total credit hours to calculate the cumulative GPA.

The GPA Formulas

To calculate quality points and cumulative GPA, apply these formulas:

$$\text{Quality Points (QP)} = \text{Grade Value} \times \text{Credit Hours}$$

$$\text{Cumulative GPA} = \frac{\sum \text{Quality Points}}{\sum \text{Credit Hours}}$$

For example, if you earn an A (4.0) in a 4-credit biology class and a B (3.0) in a 3-credit history class: the biology quality points are $4.0 \times 4 = 16.0$, and the history quality points are $3.0 \times 3 = 9.0$. Your cumulative GPA is $(16.0 + 9.0) / (4 + 3) = 25.0 / 7 = 3.57$.

Weighted vs. Unweighted GPA

Unweighted GPA: Calculated on a standard 4.0 scale regardless of class difficulty. A grade in an AP class has the same weight as a standard class.

Weighted GPA: Reflects course difficulty by adding extra weight (usually 1.0 point for AP/IB courses and 0.5 points for Honors courses) to the grade value, allowing GPA scores to go up to 5.0.

Quality points

The numeric value assigned to a letter grade multiplied by the course’s credit weight.

Credit Hour

A unit representing weekly instruction hours, used to weigh course impact on GPA.

Frequently Asked Questions

What are quality points?+

Quality points are calculated by multiplying the grade value (e.g., A = 4.0) by the number of credit hours for that class. For example, an A in a 3-credit course yields 12 quality points.

Does this calculator support plus/minus grades?+

This version uses a standard flat-scale letter grade (A=4, B=3, C=2, D=1, F=0) for simplified GPA tracking.

What is the difference between weighted and unweighted GPA?+

Unweighted GPA is capped at 4.0 regardless of course level. Weighted GPA adds extra points (like +1.0 for AP) to reflect course difficulty, scaling up to 5.0.

How do credit hours affect my GPA?+

Credit hours determine the weight of a course. A high grade in a 4-credit course raises your GPA more than the same grade in a 1-credit lab.

Can my GPA exceed 4.0?+

Yes, if your school uses a weighted GPA scale that awards extra points for Honors, AP, or IB courses, allowing a maximum of 5.0.

What is a cumulative GPA?+

Cumulative GPA is the weighted average of all grades earned across all semesters of your academic career at the institution.

How does an F affect my GPA?+

An F counts as 0 points in the GPA calculation but the credit hours are still added to the denominator, dragging your average down significantly.

What is a passing grade?+

In most US high schools and universities, a D (1.0) is the minimum passing grade to earn course credits, though some programs require a C (2.0) for major requirements.

Do pass/fail classes affect my GPA?+

No. Pass/fail classes award credits if passed but are excluded from the GPA calculation, affecting neither quality points nor the credit denominator.

What is the standard GPA requirement for college admissions?+

Requirements vary by institution. Selective universities often look for GPAs above 3.5 or 3.7, while community colleges and state schools have more flexible thresholds.
