How the GPA & College Grade Calculator Works

The GPA & College Grade Calculator by DwellixTools is an interactive, browser-based grade tracker designed for high school, college, and university students. It computes your GPA (Grade Point Average) for a single semester or combines current classes with your academic history to calculate your cumulative GPA.

This utility processes all calculations 100% locally inside your web browser. No grades, credits, or personal course names are ever transmitted to our server or any third-party databases, ensuring complete data privacy.

How to Calculate Your GPA

Standard GPA Calculation Formula

Your GPA is calculated by dividing the total number of Grade Points earned by the total number of Credits / Hours attempted:

$$\text{GPA} = \frac{\sum (\text{Grade Points} \times \text{Credits})}{\sum \text{Credits}}$$

For example, if you earned an A (4.0 points) in a 4-credit course, and a B (3.0 points) in a 3-credit course:

  • Total Points = $(4.0 \times 4) + (3.0 \times 3) = 16 + 9 = 25$
  • Total Credits = $4 + 3 = 7$
  • GPA = $25 / 7 = 3.57$
