GradeKey — Grade Calculator

GradeKey turns any assignment's point value into a complete grade conversion table - instantly.

Stop doing mental math at the grading table. Enter the total points once, and GradeKey generates every possible score, percentage, and letter grade in a single scrollable table. Built by a teacher, for teachers.

INSTANT GRADE TABLES

Type in the total points and GradeKey does the rest. Every row shows points off, points earned, the exact percentage, and the letter grade - color-coded so an A is green and an F is red at a glance.

Choose your step size to match how you actually grade:

• Whole points, fast for quizzes
• Half points, the classroom standard
• Quarter points, for detailed rubrics

FIND ANY SCORE IN SECONDS

Three ways to look up a grade, and GradeKey jumps straight to the matching row and highlights it:

• Points Off, "they lost 4 points, what's that?"
• Points Earned, "36 out of 40 is what percent?"
• Grade %, "what do they need for an 85?"

No scrolling, no scanning. Type a number, land on the answer.

GRADING SCALES THAT MATCH YOUR SCHOOL

Eight built-in presets, and GradeKey suggests the right one based on your region:

• US Standard (90/80/70/60)
• US Plus / Minus (A+, A, A-, B+ ...)
• US Strict (93/83/73/63)
• Pass / Fail
• Canada
• UK / Europe
• Australia
• Latin America

Or build your own. Rename any tier ("Pass", "Satisfactory", "Not Yet"), add or delete tiers, set any percentage cutoff, and choose exactly where the passing line falls - GradeKey draws a divider right at your threshold.

EXTRA CREDIT, HANDLED

Add bonus points and GradeKey extends the table above 100%, marking those rows "EC" in purple. See exactly what 102% or 105% looks like in points.
