Enter your current grade, how much the final counts and the grade you want. Needed = (target − current × (1 − weight)) ÷ weight: with 85% now and a final worth 25%, an 80% overall needs 65% on the exam, while 90% would need 105%, out of reach.
How to use
- Enter each course with its credits and letter grade. Add courses with Add course; the name is optional.
- Turn on Weighted to mark Honors or AP/IB classes: tap the level button on each course to switch between Reg, H and AP.
- Turn on Cumulative and enter your current GPA and credits so far to see your new overall GPA.
- Final grade: enter your current grade, how much the final counts and the grade you want. You’ll see the score you need and the scores for A, B, C and D.
- Tap any result to copy it. Your courses are saved in this browser.
- GPA = sum of (credits × grade points) ÷ total credits. A and A+ are 4.0, A− 3.7, B+ 3.3, B 3.0 and so on down to F = 0.
- Weighted GPA adds 0.5 for Honors and 1.0 for AP or IB classes (a 5.0 scale). F stays 0. Schools differ, so check your school’s policy.
- The S–F scale (S 4, A 3, B 2, C 1, F 0) is used by many Japanese universities.
- Final grade needed = (target − current × (1 − weight)) ÷ weight.
- Pass/fail and withdrawn courses usually don’t count toward GPA; leave them out.
How GPA is calculated
GPA = sum of (credits × grade points) ÷ total credits. On the common US 4.0 scale A and A+ are 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 and F 0.
Example: A in a 3-credit course, B+ in a 4-credit course, A− in 3 credits and B in 3 credits gives 12 + 13.2 + 11.1 + 9 = 45.3 grade points over 13 credits, a GPA of 3.48. A 4-credit class moves the result more than a 1-credit one, so the credits matter as much as the grades.
Weighted, cumulative and other scales
Weighted GPA, used by many US high schools, adds 0.5 for Honors and 1.0 for AP or IB classes, so an A in AP counts 5.0. F stays 0, and policies differ by school. Cumulative GPA combines your GPA so far with this term: 3.2 over 60 credits plus 3.6 over 15 credits gives (192 + 54) ÷ 75 = 3.28. The calculator also has the Korean 4.5 and 4.3 scales and the S–F scale used by many Japanese universities.
Frequently asked questions
How do I calculate my GPA?
Multiply each course's grade points by its credits, add them up and divide by the total credits. The calculator does this as you type.
What is a good GPA?
On a 4.0 scale, 3.0 is a B average and 3.5 or higher is usually considered strong. What counts as good depends on your school and goals.
What is the difference between weighted and unweighted GPA?
Unweighted GPA tops out at 4.0. Weighted GPA adds points for harder classes, such as +1.0 for AP, so it can go above 4.0.
Is an A+ worth more than an A?
On most US 4.0 scales, no: A+ and A are both 4.0. Some schools give A+ 4.3, and the Korean 4.5 scale gives A+ 4.5.
Do pass/fail classes count toward GPA?
Usually not. Pass/fail and withdrawn courses carry no grade points, so leave them out of the calculation.
How do I raise my cumulative GPA?
The more credits you already have, the less one term moves it. With 60 credits at 3.0, a 4.0 term of 15 credits raises it to 3.2.
