Whole-chart grade calculator
Every score, every percentage, every letter grade — in one view

About this tool
The EZ Grader that shows the whole chart
The free EZ Grader teachers use to calculate grades in seconds. Enter total points on the test or assignment, and get an instant score-to-percentage-to-letter-grade chart for every possible number correct. No sign-up, no login, no limits. Works on phone, tablet, or desktop — offline after load.
What this EZ grader does (and what makes it different)
Most EZ graders online show a one-shot percentage lookup. This one generates the full chart — for a 25-point test you see every score from 0/25 to 25/25, with percentage and letter grade, so you can grade a class stack without re-entering numbers. Change the total, the chart redraws instantly. Change the letter-grade cutoffs (A=90, A=93, A=95) and the chart recolors. Toggle half-point increments for 0.5-point scoring common on language/writing rubrics.
Instant full chart — not one-at-a-time lookup
Custom letter-grade cutoffs (district-specific scales)
Half-point increment mode for 0.5-point rubrics
Rounding control (up, down, nearest, none)
Print the full chart or just the row you need
Print a clean grading chart to tape inside your gradebook. Export a PDF for a substitute teacher. Or just glance at the row — a live highlight follows the score you'd enter. The calculator is stateless (nothing saved, nothing tracked), so you can use it for a single quiz or a stack of 120 finals without any setup.
Who's using it
Classroom teachers grading daily exit tickets. Substitute teachers who inherited a quiz and need a chart fast. Homeschool parents grading against a custom scale. Tutors running weekly assessments. Coaches scoring student observations. The tool doesn't care — it just does the math correctly, every time.

Loved by Educators
Hear from teachers who are saving time and providing better feedback.
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”
“More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.”
“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”
“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”
“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”
“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”
