I wanted to see the exact math behind my GPA without fighting ad-heavy calculators or maintaining a fragile spreadsheet every semester.
Keep the grading scale and worked formula beside the number.
TypeScript calculates credit-weighted SGPA, cumulative CGPA, custom percentage conversions, and cross-system GPA equivalents. Service worker caching and localStorage keep the entire app working offline as an installable PWA.
Grades, profile preferences, and custom scales stay in browser localStorage. There are no accounts, no telemetry, and zero external network calls. Shared #plan= links encode data in the URL hash without server storage.
Always verify grading rules against your institution's latest regulation handbook. GradeForge is a local planning tool, not an official academic transcript.
Calculating semester GPA and planning target grades meant fighting ad-cluttered websites or maintaining fragile spreadsheets every exam season.
Most online calculators hide the math behind a single number, making it impossible to verify whether credit weights and university rules were applied properly.
GradeForge shows the exact step-by-step worked formula beside your SGPA and CGPA across 16 regional and international grading scales plus custom scales.
Enter your subjects once, convert across global GPA scales, test what-if grade scenarios for future semesters, print a clean A4 summary, or share a read-only link, all stored offline in your browser.
