What Is a 2.8 GPA in Letter Grade?
A 2.8 cumulative GPA on the standard unweighted 4.0 scale usually reads as a solid B—about 83% if your school maps GPA to percent the way many U.S. conversion charts do. Some districts print “B” on the transcript; others round to B− when plus/minus cutoffs sit between 2.7 and 2.9.
That small labeling difference matters for scholarships and transfer rules, so treat this article as orientation—not a replacement for your handbook. When in doubt, ask whether your 2.8 is weighted, unweighted, or recalculated for class rank.
For college tables, admission context, and semester planning walkthroughs, see our full 2.8 GPA guide. The table below summarizes the letter-grade answer most students search for.
| GPA | % grade | Letter grade |
|---|---|---|
| 2.5 | ~81% | B- |
| 2.6 | ~81% | B- |
| 2.7 | 81% | B- |
| 2.8 | ~81% | B- |
| 2.9 | ~85% | B |
| 3.0 | 85% | B |
| 3.1 | ~85% | B |
2.8 GPA to letter grade on the 4.0 scale
Letter B equals 3.0 quality points and B− equals 2.7. A 2.8 average sits between those marks, which is why charts often show B with a percent near 83% rather than a strict midpoint of either letter band.
If your school uses strict letter buckets, confirm whether 2.8 rounds to B or B− before you compare yourself to published college averages—those averages may be unweighted, weighted, or recalculated.
Weighted vs unweighted at 2.8
Colleges may recalculate your record on their own 4.0 scale while ignoring weighting bonuses. A 2.8 unweighted with several AP courses can still tell a rigor story through course titles and test scores—even when the weighted line on your transcript reads higher.
Never compare your weighted 3.4 to another student’s unweighted 2.8 without context. Quote both numbers only when the application explicitly asks for the type your school reports.
Turn 2.8 into a semester plan
Copy your current courses into the multi-semester GPA tool, toggle weighted if your district awards extra points for honors or AP, then add a hypothetical next term with the grades you are aiming for.
If a single class is dragging the average down, pair the grade calculator with the final-grade tool: enter syllabus weights, see what you need on remaining exams, then feed that target back into the GPA workspace.
