High School GPA Calculator

The High School GPA Calculator is a comprehensive academic tracking tool designed specifically for high school students to calculate both weighted and unweighted GPAs for individual semesters and cumulatively across their entire high school career. Enter your course names, credit hours, letter grades, and course levels (Regular, Honors, or AP/IB), and the tool instantly calculates your semester GPA in both weighted and unweighted formats, then saves each semester to build a complete cumulative GPA record. It stores all saved semesters locally, displays a trend chart showing how your GPA has evolved over time, and is fully optimized for clean, single-page PDF exports — making it an essential companion for college applications, scholarship submissions, and personal academic planning.

What the Calculator Measures

• Unweighted GPA uses the standard 4.0 scale where letter grades are assigned point values without any adjustment for course difficulty — for example, A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0 — treating all courses equally regardless of whether they are Regular, Honors, or AP/IB.
• Weighted GPA adjusts grade point values based on course level to reflect the increased rigor of Honors and AP/IB classes — Honors courses receive an additional +0.5 points (e.g., A in Honors = 4.5), and AP/IB courses receive an additional +1.0 point (e.g., A in AP = 5.0) — giving students credit for taking more challenging coursework.
• Semester GPA is your Grade Point Average for a single semester or term, calculated using the formula: Semester GPA = Σ(Grade Points × Credits) ÷ Σ(Credits), where grade points are determined by both the letter grade and course level, and the sum is divided by the total credit hours for that semester.
• Cumulative GPA is your overall GPA across all saved semesters, weighted by total credit hours earned, calculated using the same formula but aggregating all courses from every saved semester — it reflects your entire high school academic performance up to the current point.
• GPA Trend Chart is a visual line graph that plots both your weighted and unweighted semester GPAs over time, making it easy to track academic progress, identify trends, and see how your performance has changed from semester to semester.

How the Calculation Works

• Add your courses. For each course, enter the course name (optional, for your reference), credit hours or units (typically 0.5 or 1.0 for high school courses), letter grade (e.g., A, B+, C-), and course level (Regular, Honors, or AP/IB).
• Add more courses as needed. Click “Add Course” to add additional rows for each class you are taking this semester. Remove any unwanted course by clicking the remove button on that row.
• View your semester GPA instantly. As you enter courses, the tool automatically calculates and displays both your unweighted and weighted GPAs for the current semester in the Current Semester GPA section.
• Save the semester to your cumulative record. Click “Save Semester” to add this semester’s data to your cumulative GPA history.
• Review your cumulative GPA. The Cumulative GPA section displays your overall unweighted and weighted GPAs, calculated by aggregating all courses across all saved semesters weighted by total credit hours.
• View saved semesters. A list of all saved semesters is displayed in the Saved Semesters section, showing the semester number, unweighted and weighted GPAs, and a detailed course table for each one.
• View the trend chart. An interactive line chart shows how both your weighted and unweighted GPAs have progressed across all saved semesters, giving you a clear visual picture of your academic trajectory.
• Export as PDF (optional). Use your browser’s Print menu to save your entire GPA report — including semester details, cumulative GPAs, and trend chart — as a clean, single-page PDF for easy sharing or archiving.

Why Use This Tool
