Converting a raw percentage score into a letter grade follows a standard scale in most US schools, though exact cutoffs can vary slightly by institution — this tool applies the most commonly used grading scale.
Enter any percentage from 0 to 100, and the tool instantly returns the corresponding letter grade, using the standard A/B/C/D/F scale with plus and minus modifiers at the common cutoff points.
This is useful for students quickly checking what a raw score translates to, or for anyone converting between percentage-based and letter-based grading systems for a transcript or report.

Frequently asked questions
Do all schools use the exact same percentage cutoffs?
No, cutoffs vary somewhat by school and even by individual instructor — this tool uses a commonly accepted standard scale, but always check your specific institution's syllabus for the exact grading scale that applies.
What about grades below 60%?
Scores below 60% are shown as F on this standard scale, which is the most commonly used failing-grade cutoff.
