Grade Percentage Calculator
Work out a percentage score from marks earned out of a total.
Marks into a percentage
Turning a raw score into a percentage — so many marks out of a total — is simple division, but it is the everyday calculation behind every graded test, and doing a batch of them by hand invites slips. This works out the percentage from the marks earned and the total available, quickly and correctly.
Enter the marks earned and the total to see the percentage.
From percentage to grade
A percentage is often just the first step, because it usually maps to a letter grade or a pass mark through a grading scale that varies by school and country — what counts as an A, or a pass, is not universal. So the percentage is the objective figure, and the grade it corresponds to depends on the scheme in use. For working out where a score falls, the percentage is the reliable common ground; matching it to a grade means knowing the specific scale.

Does a percentage map to the same grade everywhere?
No — grade boundaries vary by school and country, so the same percentage can be a different letter grade in different places.
Is anything uploaded?
