Easy Grader

Easy Grader (gradescalculator.net) is a free, browser-based test scoring calculator that turns the total number of questions and the number of wrong answers into a percentage, a letter grade, and a complete grading chart for the entire class. It works on any device with a web browser and requires no sign-up.

What is Easy Grader?

Easy Grader is a free online tool that calculates test scores from a question count and the number of missed answers. You enter the total questions and the wrong answers, select a grading scale, and instantly see the percentage, the letter grade, and a chart that lists every possible score for that test. It is a digital replacement for the cardboard slider graders teachers used to use, and it works for any subject or test length.

What makes Easy Grader stand out?

• Instant grading chart: Once you set the total questions, the chart shows every possible wrong/correct/percentage/letter combination, so you can grade a whole class with one setup.
• Three common grading scales: Standard (A=90, B=80, C=70, D=60), Strict (A=95, B=85, C=75, D=65), and Lenient (A=85, B=75, C=65, D=55).
• Adjustable decimal precision: Choose rounded percentages, one decimal place, or two decimal places.
• No sign-up or data storage: Everything runs in your browser; nothing you enter is saved or sent to a server.
• Cross-platform accessibility: Works on laptops, tablets, and phones without installing an app.
• Real-time recalculation: The result and chart update instantly as you change the numbers.

Who should use Easy Grader?

• Teachers grading quizzes, tests, or exams with a consistent number of questions; they set the total once and read scores from the chart for each paper.
• Students who want to know what a particular number of wrong answers means as a percentage and letter grade.
• Parents helping their children track test performance and understand grading cutoffs.

Use cases

• Grading a full test paper stack: Enter the question count, open the grading chart, and look up each student's score by the number wrong.
• Checking a single score: After a test comes back, enter the total and missed to see the percentage and letter grade in seconds.
• Applying different grading policies: Choose between standard, strict, or lenient scales to match a school's cutoffs, or use the raw percentage for a custom scale.

How does Easy Grader work?

1. Enter the total number of questions on the test.
2. Enter how many answers were wrong (count blanks as wrong).
3. Optionally pick a grading scale and decimal precision.
4. The tool subtracts wrong from total, divides by total, multiplies by 100, and matches the result to a letter grade.
5. The grading chart below shows all possible scores for that test, so you can grade multiple papers without re-entering anything.

Pricing
