Pass/fail, withdrawn and incomplete grades are ignored because they usually do not affect GPA. Check your school policy if your transcript uses a different grade scale.

What a High School GPA
Actually Measures
The one distinction, weighted vs unweighted, that trips up most students, is cleared up first
Your Grade Point Average converts every letter grade into a number, then averages those numbers across your courses. On the standard unweighted scale, an A is 4.0, and the average can’t exceed 4.0 no matter how many A’s you earn.
A weighted GPA works the same way but rewards harder classes: Honors, AP, and IB courses carry bonus points, so a top student loading up on AP can finish above 4.0. Almost every high-school GPA question comes back to which of these two your school reports, so that’s where we start.
The average for one grading period a semester, quarter, or full year. It resets each period.
Every graded course across all four years, rolled into one running average. This is the figure on your transcript.

FAQs
How is high school GPA calculated?
Convert each grade to its grade point, multiply by the course's credits, add all the grade points together, then divide by your total credits. The result is your GPA.
What's the difference between weighted and unweighted GPA?
Unweighted GPA caps at 4.0 and treats all classes equally. Weighted GPA adds bonus points for Honors, AP, and IB courses, so it can rise above 4.0.
Is high school GPA calculated by semester or by year?
Schools report a GPA each grading period and a cumulative GPA across all four years. Some average semester grades; others report full-year grades. The cumulative figure is what colleges use.
How do half credits affect my GPA?
A half-credit class counts as half a course in the average, so it influences your GPA half as much as a full-credit class with the same grade.
How do I convert a percentage or number grade to GPA?
Match your percentage to its grade point: 93–100 is 4.0, 90–92 is 3.7, and so on down the scale. Cut-offs vary slightly by school.
What is a good high school GPA?
On an unweighted 4.0 scale, 3.5+ is strong and 3.0 is solid; the U.S. average is often cited near 3.0. Selective colleges typically look for 3.7–4.0.
Does an A+ count higher than an A?
Usually not. Most high schools cap the top grade at 4.0, so an A+ and an A count the same. A few schools use a 4.3 scale where A+ is worth more.
How do AP and Honors classes change my GPA?
On a weighted scale, they add bonus points, commonly +0.5 for Honors and +1.0 for AP or IB, which can push your weighted GPA above 4.0.
Can I calculate my GPA without credit hours?
Yes. If every class carries equal weight, enter the same credit value for each one and the calculator returns a simple average of your grade points.
Do colleges use my school's GPA or recalculate it?
Many recalculate. Admissions offices often strip out non-academic classes or remove weighting to compare applicants on one consistent scale.
