GPA Calculator
Your GPA is your grade points (A = 4.0, B = 3.0 …) times each class’s credits, added up and divided by your total credits. Add your classes below to see your unweighted and weighted GPA, for one semester or all of them.
Semester GPA
3.60unweighted
3.70weighted
Over 5 credits.
To reach 3.7 after 5 more credits, you need a 3.80 next semester.
| Semester | Unweighted | Weighted | Credits |
|---|---|---|---|
| Semester 1 | 3.60 | 3.70 | 5 |
How is GPA calculated?
GPA = (grade points × credits, added up for every class) ÷ (total credits). Weighted GPA adds 0.5 for honors and 1.0 for college-level classes before multiplying (never to an F).
Worked example (high school, one credit each). English 10 A (4), Algebra II B+ (3.3), Biology A- (3.7), World History B (3), Spanish II A (4).
Unweighted: 4 + 3.3 + 3.7 + 3 + 4 = 18, divided by 5 credits = 3.60.
Weighted: English 10 is an honors class, so its A counts as 4.5. The total becomes 18.5, and 18.5 ÷ 5 = 3.70.
Worked example (college, credit hours and cumulative). Calculus I B (4 credits), English Composition A (3 credits), Psychology A- (3 credits): (3 × 4 + 4 × 3 + 3.7 × 3) ÷ 10 = 35.1 ÷ 10 = 3.51 for the semester. With a 3.20 over 30 credits before it: (3.20 × 30 + 35.1) ÷ 40 = 3.28 cumulative.
What do the grade points mean?
On the common 4.0 scale, A and A+ are 4.0, A- is 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 and F is 0. Some colleges count an A+ as 4.3, which you can choose above. To turn a percent into a letter first, use the letter grade converter.
High school or college?
In high school, most classes are one credit a year (or half a credit a semester), and many schools weight honors and college-level classes. Choose High school to see the Level column. In college, classes carry credit hours, usually 3 or 4, and GPAs are almost always unweighted. Choose College, and type each class’s credit hours.
Can I build my GPA from classes I saved?
Yes. On the grade calculator, tick Save my classes on this device and save each class. Then press Add my saved classes here: each one is added with the letter grade it had when you saved it. Everything stays in your browser.
Questions about GPA
How do I calculate my GPA?
Turn each letter grade into grade points (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0 and so on), multiply by the class’s credits, add them up and divide by the total credits. Five one-credit classes with A, B+, A-, B and A give 18 points over 5 credits: a 3.60.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the plain 4.0 scale for every class. A weighted GPA adds a bonus for harder classes: usually +0.5 for honors and +1.0 for college-level classes, so an A can count as 4.5 or 5.0. Schools choose their own bonus, so check your school’s rules. Our guide explains more.
How do credit hours change my GPA?
A class with more credits counts more. In college, an A in a 3-credit class and a B in a 4-credit class give (4.0 × 3 + 3.0 × 4) ÷ 7 = 3.43, not the 3.50 you would get by averaging the two grades.
How do I calculate my cumulative GPA?
Add the grade points from every semester and divide by every credit you have taken. Type your GPA and credits so far in “GPA so far”, add this semester’s classes, and the calculator does it. With a 3.20 over 30 credits and a 3.51 semester over 10 credits, the cumulative GPA is 3.28.
What GPA do I need next semester to raise my GPA?
Needed = (target × (credits so far + next credits) − grade points so far) ÷ next credits. With a 3.60 over 5 credits and a target of 3.70 after 5 more credits, you need a 3.80. If the answer is above 4.0, the target cannot be reached in one semester.
Do pass/fail classes count in my GPA?
Usually not. Classes graded pass/fail, and classes you withdrew from, normally carry no grade points, so leave them out. Check your school’s handbook if you are not sure.
