About Us
EasyGrader.io is a free, browser-based EZ Grader Calculator built for teachers, tutors, student teachers, and anyone who grades tests or quizzes. You enter the total number of questions, and the tool generates a complete grading chart. No math, no spreadsheets, no physical EZ Grader needed.
Why We Built This Tool
Grading papers already takes time. Looking up scores should not. A lot of teachers still use a printed EZ Grader card or do the percentage math by hand. We built EasyGrader.io to make that part instant and free, on any device, right in the browser.
There are no accounts to create, no fees, and nothing to download. You open the site, enter your question count, and the grading chart is right in front of you.
What EasyGrader.io Does
The main feature of this site is the EZ Grader Calculator. It works like this:
How the Calculator Works
Enter the total number of questions on a test or quiz. The tool generates a full grading chart that shows the grade percentage for every possible number of wrong answers, from zero wrong answers all the way to the total question count. Each row in the chart shows: number wrong, number correct, and the corresponding percentage grade.
It is the same logic as a traditional EZ Grader card, built into a free web tool that works on phones, tablets, and computers.
What the Tool Does Not Do
EasyGrader.io does not store your grades, collect student names or IDs, or connect to any school system. Every calculation happens locally in your browser. Nothing you type into the tool is sent to our servers.
Who Uses EasyGrader.io
This tool is used by:
- Elementary, middle school, and high school teachers across the United States
- Student teachers and teaching assistants
- Private tutors and homeschool educators
- Students checking their own estimated scores
If you grade papers, quizzes, or tests, this tool was made for you.
Our Standards for Accuracy and Honesty
We test the calculator regularly and correct any issues that are reported to us. The grading percentages in the chart use standard percentage-based scoring: number correct divided by total questions, multiplied by 100. This matches the most widely used grading method in US classrooms.
We do not publish claims about this tool that we cannot verify. If something on this site is wrong, we want to know. Use the Contact EasyGrader page to report anything that looks off.
Who Runs This Site
EasyGrader.io is independently owned and operated. We are not affiliated with any school, school district, state education department, or testing organization. The site is supported by display advertising, which is what allows us to keep the tool free for everyone.
