TOOLWork out your GPA in seconds
Your grade point average weights each course by its credit hours, so a heavy 4-credit class counts more than a 1-credit elective. Add each course's letter grade and credits and this calculator does the weighted math instantly — no spreadsheet needed.
How GPA is calculated
GPA = total quality points ÷ total credits
Grade points on the standard 4.0 scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7, F = 0.0.
Tips
- Cumulative GPA: enter every course from every semester to get your overall average.
- What-if planning: add a future course with a target grade to see how it would move your GPA.
- Credit weighting matters: a strong grade in a high-credit course lifts your GPA more than the same grade in a small one.
This calculator uses the common US 4.0 unweighted scale. Some schools use plus/minus variations, honors weighting, or different point values — check your institution's official policy for your recorded GPA.
Frequently asked questions
How is GPA calculated?
Multiply each course's grade points by its credit hours to get quality points, add up the quality points for all courses, then divide by the total credit hours. The result is your weighted GPA on a 4.0 scale.
What are grade points on a 4.0 scale?
A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0, C- is 1.7, D+ is 1.3, D is 1.0, D- is 0.7, and F is 0.0. These are the standard US points used to weight each course by its credits.
What is a weighted GPA?
A weighted GPA counts courses in proportion to their credit hours, so a 4-credit course affects your GPA twice as much as a 2-credit one. This calculator uses credit-weighted averaging.
