Software Developer
I built GPA Calculator because every tool I found was either cluttered with ads, locked behind a sign-up, or gave results without showing the formula. As a software developer, I wanted to build something simple and transparent - a tool that shows the math, works instantly, and never touches your data.
All GPA formulas on this site follow the standard weighted average method used by US university registrars: grade points multiplied by credit hours, divided by total credit hours. University-specific thresholds (TOPS, Honors College requirements, Dean's List cutoffs) are sourced directly from official university registrar pages.
How the Tool Works
GPA Calculator uses the standard credit-weighted GPA formula: multiply each course's grade point value by its credit hours, sum all quality points, then divide by total credit hours. This matches the method used by the vast majority of US high schools, colleges, and universities on the 4.0 scale.
Formula Accuracy
The grade point scale (A = 4.0, A- = 3.7, B+ = 3.3, and so on) and all calculation logic are verified against the registrar documentation of major US universities. Where institutions use non-standard scales, the relevant calculator page notes the difference.
