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, add or delete tiers, set any percentage cutoff, and choose exactly where the passing line falls. Hide scales you do not use and arrange the picker in your preferred order.

EXTRA CREDIT, HANDLED

Add bonus points and GradeKey extends the table above 100%, marking those rows “EC” in purple.
