Percentage to Letter Grade Calculator
Compare a percentage with sample whole-letter, plus/minus, or UK classification bands. The US-style presets include sample GPA points; the UK preset does not assign a US equivalent.
Percentage to Letter Grade Calculator
A sample whole-letter scale: A starts at 90%, B at 80%, C at 70%, and D at 60%. Scores below 60% receive F.
Why the convention matters
There is no single universal cutoff for turning a percentage into a letter grade — schools, countries, and even individual courses set their own boundaries. Use a preset only when its cutoffs match your syllabus. Otherwise, ask your instructor or registrar for the applicable scale. This tool uses the entered percentage without rounding it to a whole number.

These examples use Standard (90/80/70/60). Change the convention to compare outcomes.
Grading Notes
Not every school uses plus/minus grading.
International conventions can differ substantially from US ones.
Always confirm the exact scale in your syllabus.
How to Use
- Enter your raw percentage score (0-100)
- Choose the grading convention your school or program actually follows
- Read the sample letter grade and points, or a UK classification band without US GPA equivalence
- Switch conventions any time to compare how the same score reads under a different scale
Important Notes
- There is no single universal percentage-to-letter-grade scale — cutoffs vary by school, country, and even by course
- The +/- convention matches this site's letter-grade-to-GPA chart; the plain A/B/C/D/F convention uses a coarser 90/80/70/60 split
- The UK preset shows a simplified classification band, without US GPA points; an actual degree award depends on the applicable programme rules
- Always confirm the exact scale in your syllabus or your institution's official grading policy before relying on this result

A percentage needs a grading key.
An 85% score can receive different letter grades under different course conventions. The selected thresholds determine the result.
The condition that changes the answer.
Do not transfer one teacher's percentage bands to another course without checking. Boundary and rounding rules matter.
