GPA to Letter Grade Calculator

Compare a GPA with the nearest letter in one of three explicitly defined grade-point tables. This is a numerical comparison convention, not an official transcript conversion. It helps explain where a GPA sits between reference letters, but cannot recover course percentages or determine how an institution will evaluate your grades.

How to use this tool

1. Enter your unweighted GPA, from 0 to 4.0.
2. Choose the comparison table: plus/minus with D-, plus/minus without D-, or whole letters only.
3. Read the nearest reference letter and the exact GPA interval assigned to it.
4. Use the table to see which GPA band maps to every letter.

Formula

Letter grade = the letter whose grade-point value is closest to your GPA

The cut-off between two letters is the midpoint of their point values — for example (3.7 + 3.3) ÷ 2 = 3.5 between A- and B+. A GPA exactly on a midpoint rounds up. Points: A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3, C 2.0, C- 1.7, D+ 1.3, D 1.0, D- 0.7, F 0.

Example

A 3.45 GPA sits between B+ (3.3) and A- (3.7). The midpoint is 3.5 and 3.45 is just below it, so the nearest reference letter is B+. That does not establish a percentage average. A 3.55 GPA would round to an A-.
