Letter-grade values follow a common U.S. scale, and your school sets its own percentage cutoffs, so check your transcript when it counts.

How to Use the College GPA Calculator

01 — Enter your course

Add the course name so you can identify the class.

02 — Select your grade

Choose the letter grade recorded for the course.

03 — Enter credit hours

Use the actual credit value for the course.

Use the Add course button to include additional classes, or Clear all to reset the calculator completely.

Use your actual credit hours

Credit hours determine how much each course contributes to a credit-weighted GPA. Replace any default value with the actual number of credits shown on your transcript or course record.

How College GPA Is Calculated

GPA = Σ(Quality Points × Credit Hours) ÷ Σ(Credit Hours)

Convert

Your letter grade is mapped to quality points using the selected grading scale.

Weight

The quality points are multiplied by the course's credit hours.

Average

The total weighted quality points are divided by the total credit hours counted.

College GPA Example

CourseGradeQuality PointsCreditsContribution
BiologyA4.0416.0
HistoryB+3.339.9
Computer ScienceA-3.7311.1
SeminarB3.013.0

Total quality points = 40.0

Total credits = 11

GPA = 40.0 ÷ 11 = 3.636

Why Credit Hours Matter

College courses can carry different numbers of credits, so they do not necessarily have equal influence on a credit-weighted GPA.

4.0 × 4 credits = 16 quality points
4.0 × 1 credit = 4 quality points

The 4-credit course carries four times the credit weight of the 1-credit course when the grades are the same. This is reflected in their respective quality-point contribution.

A semester GPA summarizes the courses included in one term. A cumulative GPA combines results across multiple terms and should account for the credits represented by those terms.

Grades GradeCalculatorHQ Excludes From GPA

GradeMeaningGradeCalculatorHQ treatment
PPassExcluded
NPNo PassExcluded
WWithdrawnExcluded

Under GradeCalculatorHQ's methodology, these statuses do not contribute quality points and are excluded from the credit total used for the GPA calculation.

Your institution may apply different rules in specific circumstances, so your transcript remains the authority.

Which GPA Scale Should I Use?

Different institutions can use different quality-point mappings. Choose the grading scale that matches your school or program.

Grade4.04.3
A+4.04.3
A4.04.0
A-3.73.7
B+3.33.3
B3.03.0

If your school provides a specific grading table, use that rather than assuming every college uses the same scale.

Can I Calculate College GPA From Percentages?

A percentage does not have one universal GPA equivalent. The percentage-to-letter conversion depends on the grading policy used by your school or program.

If your grades are recorded as percentages, check your institution's grading scale before converting them to letter grades or quality points.

How Course Impact Works

GPA with the course − GPA without the course = Course impact

A positive value means the course is raising the GPA shown by the calculator. A negative value means it is lowering it.

Credit hours can affect the size of the change because the GPA is credit-weighted.

What If I Change a Grade?

You can use the calculator to model a different grade by changing the grade entered for a course and comparing the result. Change a B to an A and the calculator will recalculate the GPA using the new grade.

Planning a Future GPA

How much your GPA changes depends on your current GPA, the number of credits already counted, the grade in the new course, and the number of credits for that course.

How to Read Your Transcript for a GPA Calculation

Find the course grade

Use the final recorded grade you want included.

Find the credit hours

Use the official credit value for the course.

Check special grade codes

Look for P, NP, W, I, repeated courses, transfer credits, or other special designations.

Check the grading scale

Confirm how your institution maps letter grades to quality points.

Using the values from your official transcript is more reliable than relying on assumptions or default values.

Frequently asked questions

What is the difference between semester GPA and cumulative GPA?

A semester GPA summarizes the courses included in one term. A cumulative GPA combines results across multiple terms and should account for the credits represented by those terms.

How do credit hours affect my college GPA?

College courses can carry different numbers of credits, so they do not necessarily have equal influence on a credit-weighted GPA. A course with more credit hours has a larger impact on the final average.

Why does a 4-credit course affect GPA more than a 1-credit course?

Because the quality points for a course are multiplied by its credit hours. For example, a 4.0 grade in a 4-credit course contributes 16 quality points, while a 4.0 in a 1-credit course contributes only 4.

Why does the calculator start courses at 3 credits?

Many standard college courses are worth 3 credits, so the calculator uses this as a default. You should replace it with the actual number of credits shown on your transcript.

Do Pass, No Pass, or Withdrawn courses affect GPA?

Under GradeCalculatorHQ's methodology, statuses like P, NP, and W do not contribute quality points and are excluded from the credit total used for the GPA calculation.

What is grade replacement?

Grade replacement is an institutional policy that may allow a retaken course to replace the original grade in your official GPA. This is governed by your school, not a standard mathematical rule.

Can I calculate cumulative GPA with this calculator?

While you can enter all your past courses here, using the Cumulative GPA Calculator is generally faster because it allows you to combine your past terms' GPAs and total credits directly.

What GPA scale should I use?

Choose the grading scale that matches your school or program. Different institutions can use different quality-point mappings, such as capping an A+ at 4.0 or awarding a 4.3.

Can I calculate GPA from percentages?

A percentage does not have one universal GPA equivalent. The percentage-to-letter conversion depends entirely on the grading policy used by your school or program.

Can I use this calculator for community college?

Yes. Community colleges generally follow the same credit-weighted GPA mathematical rules as four-year universities. Make sure you select the correct grading scale for your institution.

What happens if I change one of my grades?

You can use the calculator to model a different grade by changing the grade entered for a course and comparing the result. The calculator will immediately recalculate the GPA using the new grade.
