About gpacalculator.one
Our Mission
gpacalculator.one was created with a simple mission: to provide students with free, accurate, and easy-to-use GPA calculation tools. We believe every student deserves access to tools that help them understand and track their academic performance without barriers — no sign-ups, no fees, no data collection.
Our Tools
We offer a comprehensive suite of four GPA and grade calculation tools designed to cover every student's needs:
- GPA Calculator — Calculate semester and cumulative GPA on the standard US 4.0 scale with support for multiple semesters and courses.
- CGPA Calculator — Track your cumulative GPA across all semesters with support for 4.0, 5.0, 7.0, and 10.0 grading scales used worldwide.
- Grade Calculator— Calculate your current course grade with weighted categories and use the "What Do I Need" feature to plan for exams.
- Weighted GPA Calculator — Compare weighted vs unweighted GPA for AP, Honors, IB, and Dual Enrollment courses.
Privacy First
All calculations happen entirely in your browser. We never send your grades, courses, or any personal information to a server. Your academic data stays on your device. The only data we store is your theme preference (light or dark mode) in your browser's local storage. Read our full privacy policy for more details.
How Our Calculators Work
Our calculators use standard academic formulas to ensure accuracy. The GPA calculator multiplies grade points by credit hours and divides by total credits. The CGPA calculator applies the same weighted average across semesters. The grade calculator computes weighted category averages. All calculations update in real time as you enter your data, giving you instant feedback.
Accessibility & Design
We designed gpacalculator.one to be accessible to all users. Our tools feature proper ARIA labels, keyboard navigation support, and a dark mode option for comfortable use in any lighting condition. The responsive design ensures our tools work perfectly on phones, tablets, and desktop computers.
