Who We Are

EZ Grader Online was founded in 2026 with one goal — to make grade calculation fast, simple, and completely free for every teacher and student in the United States. We saw that teachers were wasting valuable time manually converting scores to percentages and letter grades. We built the tools to fix that.

Everything on this site is free to use. No account required. No subscription. No hidden fees. You open the tool, enter your numbers, and get your answer instantly.

Our Mission

Teachers spend enough time on lesson planning, classroom management, and supporting their students. Grading calculations should never be the thing that slows them down. Our mission is to give every teacher and student in the US a reliable, accurate, and completely free grading tool they can trust.

We are constantly improving our tools and adding new calculators based on what teachers and students actually need. Every update we make is focused on one thing — making your grading faster and easier.

Why Is It Free?

EZ Grader Online is free to use and will always remain free. We keep the site running through display advertising. When you use our tools you may see ads on the page. These ads allow us to cover our costs and continue providing free tools to teachers and students.

We do not sell your data. We do not require your email. We do not charge for any feature. The tools are free, the results are instant, and your privacy is respected.
