Why map percent to a letter

Portals and transcripts often show letters; your work is graded in percent.

Transparent cutoffs

97+ A+, 93–96 A, 90–92 A−, and so on down to F below 60.

4.0 points included

A and A+ both map to 4.0; A− to 3.7; B+ to 3.3; and so on.

School policies vary

Always prefer your syllabus if cutoffs differ. The percent is the source of truth.

Frequently asked questions

What percent is an A?

On this tool’s common US scale, A− starts at 90%, A at 93%, and A+ at 97%. Many schools use a flat 90–100 = A without plus/minus.

What percent is a B, C, or D?

B band 80–89 (B−/B/B+), C band 70–79 with C+ at 77–79, C at 73–76, C− at 70–72, D band 60–69 with the same plus/minus splits, and F below 60. See the full table on the page.

Does A+ give more than 4.0 GPA?

Not on this calculator. A+ and A are both 4.0, which matches many US universities. Some schools weight A+ higher; enter custom points in the GPA tool if yours does.
