What a grade calculator does

A grade calculator turns a score into a mark using a grading key: you enter the points achieved and the maximum, and it returns the grade for that percentage. It removes the repetitive lookup work when marking a stack of tests, and lets students check for themselves what a given score is worth.

Toolra's calculator uses the German grading system (1 = very good to 6 = insufficient). The percentage thresholds are fully editable, so you can match your school's or subject's key exactly, and there is a separate mode for the upper-secondary 0–15 points scale.

How the grading key works

A grading key maps percentage ranges to grades. For example, 92–100% might be a 1, 81–91% a 2, and so on down to a 6. A linear key spaces the thresholds evenly; a key like the German IHK scheme weights the middle grades differently.

  • Enter points and maximum — the percentage and grade update instantly.
  • Adjust any threshold to match your own key.
  • Switch to the 0–15 points scale for the upper secondary level.

Useful in the classroom

  • Mark class tests and exams without re-deriving the key each time.
  • Use one shared key across parallel classes for fair, consistent grades.
  • Show the key on the whiteboard so grading is transparent.
  • Averaging several grades afterwards? Use the grade average calculator.
