GPA Calculator Formula / How It Works

This tool runs local browser-based JavaScript to compute GPAs. In Semester mode, it converts letter grades to numeric values using standard 4.0 weights, adds course bonuses if weighted is enabled (capped at 5.0 per course), multiplies each value by credit hours, and divides by total credits. In Cumulative mode, it combines weighted products of past and present semesters.

Formula:Semester GPA = Σ(Grade Points × Credits) / Σ(Credits); Cumulative GPA = (Current GPA × Current Credits + Semester GPA × Semester Credits) / Total Credits
Example Calculation:

For example, if you take a 3-credit AP course (A grade = 5.0 weighted points) and a 3-credit Regular course (B grade = 3.0 points), your weighted semester GPA is: (5.0 × 3 + 3.0 × 3) / 6 = 4.00.

Frequently Asked Questions

It calculates your GPA using the standard 4.0 scale: multiply each course's grade points by its credit hours, sum all the results, then divide by the total credit hours. This is the same method used by most US colleges and universities.

It uses the standard US 4.0 scale: A = 4.0, A– = 3.7, B+ = 3.3, B = 3.0, B– = 2.7, C+ = 2.3, C = 2.0, C– = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Some schools use slightly different scales; adjust for your institution if needed.

Yes. Add all courses from all semesters you want to include, with their credit hours and grades. The calculator will compute your cumulative GPA across all entered courses.

Most US colleges require a 3.5 GPA for Cum Laude, 3.7 for Magna Cum Laude, and 3.9 for Summa Cum Laude, though exact thresholds vary by institution. Check your school's specific requirements.
