How GPA is calculated

Your GPA is a credit-weighted average of grade points: each course's grade points are multiplied by its credit hours, the results are added up, and the total is divided by the total credit hours. A 4-credit A counts twice as much as a 2-credit A.

Standard 4.0 grade-point table

This calculator uses the standard unweighted 4.0 scale used by most US colleges and high schools:

GradePointsGradePoints
A+4.0C+2.3
A4.0C2.0
A-3.7C-1.7
B+3.3D+1.3
B3.0D1.0
B-2.7D-0.7
F0.0

Worked example

Three courses: English (3 credits, A = 4.0), Math (4 credits, B+ = 3.3), History (3 credits, B = 3.0). Grade points: 3 × 4.0 + 4 × 3.3 + 3 × 3.0 = 12 + 13.2 + 9 = 34.2. Total credits: 10. GPA = 34.2 ÷ 10 = 3.42.

The what-if planner

Enter a target GPA and how many credits you still plan to take. The planner solves for the average grade points you need in those future courses. If the needed average is above 4.0, the target is mathematically out of reach with the remaining credits, and the tool tells you so.

Limitations

Schools differ: some weight honors or AP courses above 4.0, some use different plus/minus values, and some exclude pass/fail courses differently. This calculator uses the plain unweighted 4.0 scale. Always check your school's grading policy for official figures.

Frequently asked questions

How is GPA calculated?

Multiply each course's grade points by its credit hours, add those products, and divide by the total credit hours. That credit-weighted average is your GPA.

What is a good GPA?

On a 4.0 scale, 3.0 is a B average and 3.5 or higher is generally considered strong for college applications and scholarships. Standards vary by school and program.

What is the difference between weighted and unweighted GPA?

Unweighted GPA caps at 4.0 and treats all courses equally. Weighted GPA gives extra points for honors, AP, or IB courses and can exceed 4.0. This calculator uses the unweighted 4.0 scale.

Do plus and minus grades change my GPA?

Usually yes. On the standard scale, a B+ is 3.3 grade points while a B is 3.0 and a B- is 2.7. Some schools do not use plus/minus grades at all.

Can I raise my GPA with one semester of good grades?

It depends on how many credits you already have. GPA moves slowly once many credits are banked, because new grades are averaged with all previous ones. The what-if planner above shows exactly what average you need.
