Calculate your grade point average from letter grades and credit hours. Get your term GPA, a weighted GPA that adds a point for Honors, AP and IB classes, and your new cumulative GPA when you add a previous GPA and credits.

How to use the GPA calculator

  1. List your courses, one per line, as course name, grade, credits — for example “Calculus, B+, 4”.
  2. Use letter grades (A, A-, B+ …) or grade points (3.7).
  3. Tick Weighted GPA to add a point for courses with Honors, AP or IB in the name.
  4. For a cumulative GPA, add your previous GPA and previous credits.

You’ll see this term’s GPA, the total credits and quality points, your new cumulative GPA and a table of each course.

The GPA formula

GPA = Σ (grade points × credits) ÷ Σ credits

Grade points (4.0 scale)

GradePointsGradePoints
A+ / A4.0C+2.3
A-3.7C2.0
B+3.3C-1.7
B3.0D+1.3
B-2.7D1.0
F0.0

Worked example

CourseGradeCreditsQuality points
EnglishA312.0
CalculusB+413.2
ChemistryA-414.8
HistoryB39.0

Total = 49 quality points over 14 credits → GPA 3.50.

If your previous cumulative GPA was 3.2 over 30 credits: (3.2 × 30 + 49) ÷ 44 = 3.30.

Weighted vs unweighted GPA

An unweighted GPA treats every class the same, so the maximum is 4.0. A weighted GPA rewards harder classes, so the maximum can reach 5.0. Colleges often recalculate GPAs their own way, so report what your school’s transcript shows.

Raising your GPA

  • Credits matter. A good grade in a 4-credit class lifts your GPA more than in a 1-credit class.
  • Early terms weigh less as you go. The more credits you’ve completed, the harder it is to move your cumulative GPA — but steady improvement still shows on your transcript.
  • Check retake policies. Some schools replace a failed grade if you retake the course.
  • Ask for help early from teachers, tutors and study groups.

Outside the US

The 4.0 GPA scale is mainly used in the United States and Canada. Other countries use percentages, the UK degree classification system, the ECTS grades in Europe or CGPA on a 10-point scale in India. Conversions between systems are set by each university, so check with the institution you’re applying to.

Frequently asked questions

How is GPA calculated?

Each letter grade is turned into grade points (A = 4.0, B = 3.0 and so on), multiplied by the course’s credit hours to give quality points, and the total quality points are divided by the total credits.

What is my GPA with an A, B+, A- and B?

With 3, 4, 4 and 3 credits: (4.0 × 3) + (3.3 × 4) + (3.7 × 4) + (3.0 × 3) = 49 quality points over 14 credits = a 3.50 GPA.

What is a weighted GPA?

Many US high schools add a point for advanced classes such as Honors, AP and IB, so an A in an AP class counts as 5.0. Tick “Weighted GPA” and include Honors, AP or IB in the course name.

How do I calculate my cumulative GPA?

Enter your previous cumulative GPA and the credits it covers. The calculator combines them with this term’s quality points: (old GPA × old credits + new quality points) ÷ total credits.

What is a good GPA?

On the 4.0 scale, 3.0 (a B average) is often seen as good and 3.5 or above as very good. Competitive colleges and scholarships may expect more. Requirements vary — check with the school or programme.

My school uses a different scale. Can I still use this?

Yes. Type the grade points instead of letters — for example 3.5 — and the calculator uses those numbers. Some schools give A+ a 4.3; enter 4.3 if yours does.
