How to Use the GPA Calculator
Need to know where your grades stand? This lets you add your courses, pick your scale, and see your GPA instantly. You can even save semesters to track your cumulative average over time.
- Choose your GPA scale — Standard (4.0) or Weighted (5.0 AP/Honors) — using the tabs at the top. Weighted mode adds a course type dropdown for Honors and AP/IB classes.
- Enter your course details — name, credit hours, and letter grade. In weighted mode, also pick the course type (Regular, Honors, or AP/IB).
- Add more courses with the "+ Add Course" button. Remove any row by clicking the × next to it.
- Click Calculate GPA to see your semester GPA, total credits, quality points, and a visual grade distribution chart.
- Save your semester with the "Save Semester" button to start building a cumulative GPA history across multiple terms.
- Use the Target GPA calculator to find out what grade average you need in future courses to hit a specific goal.
- Run the Academic Impact Simulator (appears after Calculate) to see which course move matters most. It ranks every course by how much your GPA would rise if you upgraded it, highlights the biggest lever, and lets you simulate a grade improvement or retake under your school's policy (replace vs count-both) — answering "which class is worth retaking?" and "how much does that retake actually help?".

Frequently Asked Questions
How is GPA calculated?
Multiply each course's grade points by its credit hours, add all those quality points up, then divide by the total credit hours. So an A (4.0) in a 3-credit course gives you 12 quality points, and those accumulate across all your courses to produce your GPA.
What is the difference between weighted and unweighted GPA?
Unweighted uses a standard 4.0 scale — an A is always 4.0 no matter the class. Weighted gives extra points for harder courses: Honors adds 0.5, AP/IB adds 1.0 to the base grade, so an A in AP could be a 5.0.
Can I calculate my cumulative GPA over multiple semesters?
Yes. Calculate each semester, hit "Save Semester", and they'll stack up in your history. The cumulative GPA factors in the credit weight of every course across all saved semesters.
What is the target GPA calculator?
It tells you the minimum average grade you need in your remaining courses to reach a specific cumulative GPA goal. Just enter your current GPA, total credits so far, your target GPA, and how many future credits you'll take.
Can I export my results?
You can either copy results to your clipboard or download them as a CSV file. Both options are available for individual semester results and your full semester history.
What is the Academic Impact Simulator?
Appearing after you calculate, it shows which of your courses has the biggest effect on your GPA if improved. For each course it estimates the GPA change from upgrading it to an A and lets you simulate retaking a course under your school's policy — "Replace" (only the new grade counts) or "Count both" (old and new grades both count, as some schools require). This tells you the precise benefit of a retake before you spend the time or money on it.
