GPA Calculator — Weighted GPA on a 4.0 Scale
A GPA calculator works out your grade point average from your courses. Enter each course's grade and credit hours, and it calculates your weighted GPA on the 4.0 scale, plus your total credits.
Letter-grade scale
| Grade | Points | Grade | Points |
|---|---|---|---|
| A | 4.0 | B- | 2.7 |
| A- | 3.7 | C+ | 2.3 |
| B+ | 3.3 | C | 2.0 |
| B | 3.0 | C- | 1.7 |
| — | — | D+ / D / F | 1.3 / 1.0 / 0 |
How it works
- Add a course, choose its letter grade and enter its credit hours.
- Add as many courses as you need — the GPA updates instantly.
- Your weighted GPA, total grade points and total credits appear above.
Formula
Worked example
Three courses: an A in a 4-credit course (4.0 × 4 = 16 points), a B in a 3-credit course (3.0 × 3 = 9 points) and a C in a 2-credit course (2.0 × 2 = 4 points). Total grade points = 29, total credits = 9, so GPA = 29 ÷ 9 = 3.22.
Frequently asked questions
How do I calculate my GPA?
Multiply each course grade value by its credits, add up the grade points, then divide by your total credits. This calculator does it automatically.
What is a good GPA on the 4.0 scale?
A GPA of 3.5 or above is usually considered good, and 3.7 or above is often needed for competitive programmes. A 3.0 is a B average. Standards vary by school and country.
How are grades weighted in GPA?
Each grade has a value on the 4.0 scale — A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0, with plus and minus grades in between. Harder courses with more credits count more.
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every course equally on the 4.0 scale. A weighted GPA gives extra points for honours or AP courses. This calculator uses the standard unweighted 4.0 values.
Can I calculate GPA for one semester?
Yes — enter only this semester's courses to get your semester GPA, or enter all your courses together for your cumulative GPA.
What GPA do I need for university?
It depends on the university. Many accept students with a GPA of 2.5 to 3.0, while selective universities often look for 3.5 or higher, along with test scores and other factors.
