Percentage to GPA Converter

On the standard conversion table, 88% is a B+, worth 3.3 GPA points — the B+ band runs from 87% to 89%. Enter it above and the converter highlights the band in the table so you can see the neighbouring letters too.

91% is an A−, worth 3.7 grade points — the A− band covers 90–92%. One percentage point either way changes the answer: 89% is a B+ (3.3) and 93% is an A (4.0), which is why boundary scores matter so much in percentage-graded courses.

On the standard table, the A band starts at 93% — so every course averaged at 93% or above holds a 4.0. But remember GPA is averaged from letter grades course by course, not converted from one big percentage: a single course at 88% (3.3) pulls a semester of A's below 4.0 no matter how high the others are.

On the standard table, 72% is a C−, worth 1.7 points — the C− band covers 70–72%. A D+ starts at 67%. Schools with different cutoffs can place 72% differently, but under the common US convention used here it is the top of the C− band, one point short of a plain C.

Convert each course's percentage to its letter and points first (this page), then average the points weighted by credits — that second step is the GPA calculator's job, and it matters: a 4-credit course at 3.0 moves your GPA more than a 1-credit course at 4.0 lifts it. Converting your overall percentage average in one step gives a different, less accurate number.

As a reference, yes; as your transcript's truth, no. This converter uses the standard College Board-style 4.0 table, the most common US convention. If your school publishes its own cutoffs — some set an A at 94, some use no plus/minus grades — compute with their table. The differences show up at band edges, which is exactly where it matters.
