If you are asking what is an A in percentage, the short answer is 90% to 100% on the most common school scale. Some schools split the A into A+, A and A-, and each one has its own percent range. This guide shows every letter in percent, so you can check your own grade in seconds.
What Is an A in Percentage? (Quick Answer)
On the 10-point scale, an A is 90–100%. On the plus/minus scale, an A is 93–96%, an A- is 90–92%, and an A+ is 97–100%. So the answer to what is an A in percentage depends on the scale your school uses. Both versions are in the tables below.
Letter Grade to Percentage Chart (Plus/Minus Scale)

|---|---|
| A+ | 97–100% |
| A | 93–96% |
| A- | 90–92% |
| B+ | 87–89% |
| B | 83–86% |
| B- | 80–82% |
| C+ | 77–79% |
| C | 73–76% |
| C- | 70–72% |
| D+ | 67–69% |
| D | 63–66% |
| D- | 60–62% |
| F | Below 60% |
Letter Grade to Percentage Chart (Simple A–F Scale)
Many middle and high schools skip the plus and minus. On this simple scale, the answer to what is an A in percentage is easy: 90–100%. A B is 80–89%, a C is 70–79%, a D is 60–69%, and anything below 60% is an F.
| Letter Grade | Percentage Range |
|---|---|
| A | 90–100% |
| B | 80–89% |
| C | 70–79% |
| D | 60–69% |
| F | Below 60% |
What Percent Is an A-, B- or C-?
Minus grades are the ones people search for most. An A- is 90–92%. A B- is 80–82%. A C- is 70–72%. A D- is 60–62%. A minus grade is always the lowest slice of its letter, so a 90% is an A- and not an A.
Plus grades sit at the top of each letter. A B+ is 87–89%, a C+ is 77–79%, and a D+ is 67–69%.
Why the Same Letter Can Mean a Different Percentage
Schools do not all use the same scale. On a strict 7-point scale, an A starts at 93%. On the common 10-point scale it starts at 90%. On a lenient 12-point scale it starts at 88%. That is why what is an A in percentage at one school can be different at another. If you are not sure which scale your teacher uses, look in your syllabus for the lowest percent that earns an A, then enter that width in our grading scale calculator to see every other cutoff.
How to Check Your Own Grade
If you already have a percent, type it into the percentage to letter grade tool. If you only have a test score, such as 23 out of 30, use the grade calculator. It shows the exact percent (76.7%) and the letter (C). A score of 76.7% is just under the 77% line, so it is a C and not a C+.
Whatever chart you use, your syllabus or school is the final word on what is an A in percentage for your class.
