About Grade Percentage Calculator
We built Grade Percentage Calculator to solve one simple problem: give students and educators the fastest, cleanest, and most accurate grade calculation experience on the web.
Why We Built This
Most online grade calculators are cluttered with intrusive popups, slow loading times, outdated formulas, and distracting ad banners. When you finish a test or receive assignment marks, you shouldn't have to navigate through multiple pages or wait for heavy scripts to know your percentage.
Our utility is focused on speed, transparency, and clarity. The tool loads instantly, requires no account creation, and delivers the percentage, standard US letter grade, and formula breakdown in less than a second.
Our Commitment to Transparency
Every single calculation happens locally in your browser engine. We never transmit your scores, course names, or inputs to any server.
We follow the widely adopted standard US 10-point scale with plus/minus subdivisions, while providing an interactive cutoff customizer for non-standard syllabi.
Feedback & Inquiries
