GPA Calculator
Calculate your semester and cumulative GPA on a 4.0 or 5.0 scale with support for weighted and unweighted grades.
GPA Calculator tool
Example
Input: Mathematics A (4 credits), English B+ (3 credits), Physics B (4 credits), unweighted 4.0 scale
Result: Semester GPA 3.445 / 4.0 (11 credit hours, 37.90 quality points)
(4.0 x 4 + 3.3 x 3 + 3.0 x 4) / 11 credits = 37.9 / 11 = 3.445.
Grade Points by Letter Grade
| Letter | Unweighted (4.0) | Honors | AP / IB |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
Honors and AP / IB columns apply only with the Weighted (5.0) switch on. Schools may differ.
- Use the standard 4.0 scale, or turn on the Weighted (5.0) toggle to add honors and AP or IB bonuses.
- Add each course with its name, credit hours, and letter grade for the current semester, plus its level on the weighted scale.
- View your calculated semester GPA and the grade points and quality points of each course in the breakdown.
- Enter your prior cumulative GPA and total credit hours to compute your updated cumulative GPA.
- Change the letter grades to see how different results would affect your semester and cumulative GPA.
How GPA Is Calculated on a 4.0 Scale
GPA (grade point average) is the average of your grade points, weighted by credit hours. Each letter grade has a point value, such as A = 4.0 and B = 3.0. You multiply it by the course credits, add these up and divide by the total credits. An A in a 4-credit class, a B+ in a 3-credit class and a B in a 4-credit class give a 3.445 GPA.
The product of grade points and credits is called quality points. In the example, 4.0 x 4 + 3.3 x 3 + 3.0 x 4 = 37.9 quality points, and 37.9 / 11 credits = 3.445. The breakdown table lists each course's points and quality points. Big courses move your GPA more than small ones, so a C in a 4-credit class hurts more than a C in a 1-credit lab. Turn on the Weighted (5.0) switch if your high school gives extra points for harder classes. Honors courses add 0.5 and AP or IB courses add 1.0, so an A in AP counts as 5.0. No bonus is added to an F. The tool then shows your unweighted 4.0 GPA as well, since many colleges look at both. Weighting rules differ by school, so check how yours does it.
For a cumulative GPA, enter your previous GPA and the credit hours it covers. The tool combines them with this term's courses using quality points, not a simple average of two GPAs. Change a course's letter grade to see how a better or worse result would move your GPA. To see how a class grade is built from assignments, use the Grade Calculator.
