Convert any percentage into its corresponding letter grade.
Letter Grade
A
Once you know your percentage score, this tool converts it into a letter grade โ the format many report cards and transcripts actually display, rather than a raw number.
It uses a commonly seen grading scale as the default, shown openly below so you can compare it against your own institution's official grade boundaries, which can vary.
Formula
90-100 = A+ ยท 80-89 = A ยท 70-79 = B+ ยท 60-69 = B ยท 50-59 = C ยท 40-49 = D ยท Below 40 = F
This is a common scale, not a universal standard โ your school or university may use different boundaries.
Worked Example
Worked example
Grading scales vary a lot
Different countries, boards, and even individual universities use meaningfully different grade boundaries โ some use a stricter scale where 90%+ is required for an A, others are more lenient. Always check your own institution's official grading table if the exact letter grade matters for a transcript or application.
Where this is useful
Quickly translating a raw percentage or exam score into a familiar letter grade, sanity-checking a report card, or getting a rough sense of standing before official results are released.
