How the GPA Calculator Works
This calculator converts your letter grades to grade points using the standard 4.0 scale, then calculates a weighted average based on credit hours. It shows both unweighted (pure 4.0 scale) and weighted GPA (which adds bonus points for rigorous courses).
Unweighted GPA = Sum(grade_points x credits) / Sum(credits)
Weighted GPA = Sum((grade_points + bonus) x credits) / Sum(credits)
Calculate your current GPA and see how upcoming grades will change it.
College applicants
Know your unweighted GPA before submitting applications so there are no surprises.
Parents and guardians
Track academic progress and understand how weighted courses affect the overall GPA.
School counselors
Quickly estimate a student's GPA during advising sessions.
When Should You Use It?
Before college application season to know your exact GPA
After semester grades post to update your running GPA
To see how one bad grade affects your overall average
To project what grade you need in a class to hit a target GPA
How to Use the Calculator
1
Enter each course name
Type the subject name so you can identify courses in the breakdown. This field is optional - the GPA calculates without names.
2
Select the letter grade
Choose the letter grade you received or expect to receive. A+ and A are both worth 4.0 on the standard scale.
3
Set credit hours
Most high school classes are 1 credit per semester. Half-credit electives are 0.5. Full-year lab sciences may be 1 or 2 credits depending on your school.
4
Choose the course type
Select Regular, Honors, AP, or IB. This adds the weighting bonus. If you are not sure, check your transcript or class schedule.
5
Add all your courses
Click Add Course to include more classes. Your GPA updates live as you add and edit courses.
Example Calculation
Three courses: English (A, Regular, 1 credit), AP Biology (B+, AP, 1 credit), Honors Math (A-, Honors, 1 credit).
English A (4.0 x 1) = 4.0 unweighted, 4.0 weighted
AP Bio B+ (3.3 + 1.0 bonus x 1) = 3.3 unweighted, 4.3 weighted
Honors Math A- (3.7 + 0.5 bonus x 1) = 3.7 unweighted, 4.2 weighted
Unweighted GPA = (4.0 + 3.3 + 3.7) / 3 = 3.67
Weighted GPA = (4.0 + 4.3 + 4.2) / 3 = 4.17

Common Mistakes to Avoid
!
Using weighted GPA when colleges ask for unweighted
Most college applications ask for your unweighted GPA. Using your weighted GPA (which can exceed 4.0) will misrepresent your standing. Use the unweighted figure unless specifically asked for weighted.
!
Not matching your school's weighting scale
Some schools use +0.5/+1.0, others use +1.0/+1.5. If your school uses a different bonus scale, this calculator will not match your transcript exactly. Check with your guidance counselor.
!
Ignoring credit hours for different classes
A 2-credit lab class counts twice as much as a 1-credit elective. If all your best grades are in low-credit classes, your GPA calculation may come out different from your official transcript.
!
Confusing semester GPA with cumulative GPA
This calculator gives your overall GPA for all entered courses. If you want just this semester, enter only this semester's courses. For cumulative GPA, enter every course from all semesters.
Frequently Asked Questions
An unweighted GPA uses a 4.0 scale for all courses regardless of difficulty. A weighted GPA adds bonus points for harder courses: typically +0.5 for Honors and +1.0 for AP or IB classes. A weighted GPA can exceed 4.0. Most colleges use unweighted GPA for comparison across schools, since weighting scales vary by district.

Pro Tip
Raising a 3.3 GPA to 3.5 requires bringing your grade average up by roughly half a letter grade. If you have 10 courses on record, you need about a 3.5 average on your next 5 courses to get there.
