GPA Calculator

1. Enter the credit hours for each course, in order and separated by commas.
2. Enter each course grade as a grade point on the 4.0 scale, in the same order.
3. Read your GPA, the total credit hours and your standing, all updating as you type.

Here is what each result means:

GPA, the grade point average, is the standard way US schools and many others summarise academic performance in a single number on a 4.0 scale. Each letter grade is worth a number of grade points, an A being 4 and an F being 0, and courses count in proportion to their credit hours.

Because it is credit-weighted, a strong grade in a heavy four-credit course moves your GPA more than the same grade in a one-credit elective. That weighting is what separates a GPA from a plain average of your grades.

It multiplies each course grade point by its credit hours, adds those quality points, and divides by the total credits.

The product of credits and grade point for a course is called its quality points. Summing quality points across every course and dividing by the total credit hours gives the weighted average that is your GPA.

1. Convert each letter grade to a grade point: A=4, B=3, C=2, D=1, F=0.
2. Multiply each grade point by that course credit hours.
3. Add the results and divide by the total credit hours.

Plus and minus grades add a third of a point either way, such as 3.7 for an A minus or 3.3 for a B plus.

Take four courses: a 3-credit A, a 4-credit A, a 3-credit A minus and a 3-credit B plus. The grade points are 4, 4, 3.7 and 3.3. Quality points are 3x4 + 4x4 + 3x3.7 + 3x3.3 = 12 + 16 + 11.1 + 9.9 = 49, over 13 total credits.

Dividing gives 49 / 13 = 3.77, a magna cum laude range result. Notice the heavier 4-credit A pulls the average up more than the lighter courses.

By contrast, three equal 3-credit courses graded A, A and C give quality points of 12 + 12 + 6 = 30 over 9 credits, a GPA of about 3.33, showing how one weaker grade drags an otherwise strong set down.

Most US schools map letters to points on this common scale, though yours may differ slightly.

To convert a raw score into a percentage first, the marks percentage calculator is the quicker starting point.

Your GPA reacts to more than just your grades, and understanding the levers helps you plan.

Credit Weighting

High-credit courses move your GPA most, so a strong grade in a four-credit class counts far more than in a one-credit elective.

Plus and Minus Grades

An A minus or B plus shifts a course by a third of a point, which adds up across a full schedule.

Cumulative Versus Semester

A single semester GPA can swing sharply, while a cumulative GPA across many credits moves more slowly.

Retakes and Pass or Fail

Repeated courses and pass or fail grades are handled differently by each school, and can change the count of graded credits.

Tracking a Semester

Enter your expected grades to see the GPA you are on course for before final marks are posted.

Planning for a Target

Test which grades you would need in remaining courses to reach a scholarship or honors threshold.

Applications and Transfers

Many programs list a minimum GPA, so a quick calculation shows where you stand against it.

1. Averaging Grades Without Credits

A plain average of grade points ignores credit weighting and gives the wrong GPA. Always weight by credits.

2. Mismatched Lists

Each course needs both a credit hour and a grade point in the same order. A missing entry skews the result.

3. Using a Different Scale

This tool uses the 4.0 scale. If your school uses a 10-point or percentage scale, convert first.

4. Forgetting Plus and Minus Values

Treating an A minus as a full 4.0 inflates your GPA. Use 3.7 for A minus and 3.3 for B plus.

5. Mixing Semester and Cumulative

Decide whether you are calculating one semester or your whole record, and enter only those courses.

The math is exact for the credits and grade points you enter, but grading systems differ between schools.

Multiply each course grade point by its credit hours, add the results, and divide by the total credit hours. This calculator does that from your two lists.

It is your average grade where an A is 4 points, B is 3, C is 2, D is 1 and F is 0, weighted by how many credit hours each course carries.

On a 4.0 scale, 3.5 and above is typically strong and often reaches honors ranges, 3.0 is solid, and below 2.0 usually falls under academic warning.

They shift a course by about a third of a point. An A minus is 3.7 and a B plus is 3.3, so they matter across a full schedule.

GPA usually refers to a grade point average on the 4.0 scale, often for a term. CGPA is a cumulative average, and many countries use a 10-point CGPA instead.

First map your percentage to a letter grade using your school scale, then use that grade point. Conversions vary, so check your institution first.

Yes. A GPA is credit-weighted, so heavier courses count more. Averaging grade points without credits gives an incorrect GPA.

No. It uses a standard unweighted 4.0 scale. Some schools add a bonus for honors or advanced courses, which this tool does not apply.

No. The calculation runs in your browser, and nothing you enter is sent anywhere unless you Save a result, which stays on this device only.
