High School GPA Calculator
Enter your courses, grades, and course types to get your unweighted GPA (4.0 scale) and weighted GPA (5.0 scale) in seconds. Add AP, IB, and Honors classes to see the full picture, include prior semester results for a true cumulative GPA, and understand exactly what your number means for college admissions.
Weighted vs. unweighted GPA: what is the difference?
Your unweighted GPA uses the standard 4.0 scale for every course regardless of difficulty. An A in gym class counts the same as an A in AP Chemistry. Your weighted GPA adds a difficulty bonus before averaging: most systems add 0.5 for Honors and Pre-AP courses (max 4.5) and 1.0 for AP, IB, and Dual Enrollment courses (max 5.0). That means a B in AP Physics earns 4.0 weighted points versus 3.0 unweighted, reflecting the extra challenge. Colleges receive both numbers; many recalculate GPA on their own scale and focus on core academic subjects, but a high weighted GPA signals that you challenged yourself, not just that you earned high grades.
How this calculator works
Select a letter grade and course type for each class you took this semester. The calculator converts every grade to its 4.0-scale value, adds the course-type bonus for Honors or AP/IB/Dual courses, then averages those points across all courses. The result is your semester GPA on both scales. Toggle "Include prior semesters" to enter your existing cumulative GPA and credits; the calculator then combines prior quality points with current ones to give your true cumulative GPA. The course breakdown table shows exactly what each class contributed.
Cumulative GPA and your high school transcript
Colleges and scholarship programs see your cumulative GPA: the average of all four years, not just the most recent semester. Your cumulative GPA is calculated by summing quality points across every graded course and dividing by total credits earned, not by averaging individual semester GPAs. Because of this, a single strong semester has less impact when you already have many credits, but a bad freshman semester becomes progressively less damaging as you add good grades. To compute cumulative GPA in this calculator, turn on "Include prior semesters" and enter the values from your most recent transcript.
GPA benchmarks for college admissions
While there is no universal cutoff, the following unweighted GPA ranges give a rough guide to competitiveness. Highly selective universities (acceptance rates below 15 percent) typically enroll students with unweighted GPAs of 3.8 or above. Selective schools (15 to 40 percent) generally look for 3.5 or above. Most four-year colleges have minimums around 2.5 to 3.0. Community colleges and open-enrollment schools accept students at any GPA. Your course rigor matters as much as the number itself: a 3.6 from a schedule packed with AP courses will usually outrank a 4.0 from lower-level classes in the eyes of selective admissions offices. Be aware that many colleges recalculate GPA by stripping out PE, health, and elective courses, and count only five core academic subjects.

Frequently asked questions
What is the difference between a weighted and unweighted GPA?
An unweighted GPA treats every course the same on the 4.0 scale: an A is 4.0 no matter how hard the class. A weighted GPA adds a bonus for more rigorous courses: typically +0.5 for Honors and +1.0 for AP, IB, or Dual Enrollment, so the scale extends to 4.5 or 5.0. Colleges receive both, and many recalculate on their own scale, so neither number tells the whole story without context.
Do AP and IB courses help my GPA even if I earn a B?
Yes. On the weighted scale, a B in an AP or IB course earns 4.0 weighted points compared to 3.0 for a B in a regular class. The difference is even more meaningful for colleges that value course rigor, because a B in AP Calculus demonstrates more academic stretch than an A in a lower-level math course.
How do I calculate my cumulative high school GPA?
Add up the grade points for every course across all semesters (grade-point value times credit hours, normally 1 credit per class) and divide by the total number of credits. Avoid simply averaging your semester GPAs because that ignores the fact that different semesters may have different numbers of courses. Use the "Include prior semesters" toggle in this calculator to do the math automatically.
What GPA do I need for college?
There is no single answer because requirements vary by institution. As a rough guide: highly selective schools (Ivy League and similar) typically enroll students with unweighted GPAs of 3.8 or above; selective schools want 3.5 or above; most four-year colleges look for at least 2.5 to 3.0. Community colleges and open-enrollment institutions generally do not use GPA as an admissions filter. Always check the requirements of the specific schools you are targeting.
Why might my calculated GPA differ from my transcript?
Schools vary in how they weight courses, which classes count toward GPA, and whether they use plus/minus grades or round to the nearest letter. Some districts cap AP bonuses at 5.0 while others use 4.5. Pass/fail, transfer credits, and repeated courses may be handled differently. This calculator uses the most common US system, but always treat your official transcript as the authoritative source.
How many AP or Honors courses should I take?
Balance rigor with the grades you can realistically achieve. A common counselor rule of thumb is to take the most challenging schedule where you can still earn Bs or above. Taking five AP courses and earning Cs will usually hurt your application more than taking three AP courses and earning As. Most selective colleges suggest that 5 to 8 AP or IB courses over four years is competitive, though quality and grade are more important than raw count.
