About Grade Calculator
Empowering students, educators, and parents worldwide with fast, transparent, and accurate grade calculation tools.
Our Mission
At Grade Calculator (gradecalculator.dev), we believe that every student deserves clear, transparent insight into their academic performance. Calculating semester averages, final exam targets, and GPA should not require confusing spreadsheets or ad-cluttered websites that lag on mobile devices.
Our suite of 15+ calculators is built on modern web technologies to ensure lightning-fast responsiveness, 100% browser-side data privacy, and mathematical rigor across every formula.
Mathematical Rigor
Every calculation formula—from weighted harmonic contributions to decimal quality points—is verified and tested against standard institutional benchmarks.
Privacy-First Architecture
We never store, transmit, or monetize your coursework grades. All calculations execute directly in your browser's JavaScript runtime.
Always Free & Accessible
No paywalls, no forced logins, and no intrusive popups. Built to conform to modern WCAG accessibility guidelines.
