Grade Percentage Calculator

Turn a score out of a total into a percentage and letter grade.

After a test the first question is always the same: what percentage did I get, and what letter grade is that? Dividing your score by the total and mapping it to a grade is simple math, but doing it quickly and consistently for every assignment adds up.

Enter the points you earned and the total possible, and this calculator gives your percentage and the corresponding letter grade on the standard US scale. Use it to check a returned test, project a needed score, or tally an assignment fast.
