Grade D+ sits at 67 to 69 percent on the standard US grading scale and equals a 1.3 GPA on the 4.0 scale. It is one of the D-tier letters in the A-through-F sequence used at most US colleges and high schools, and counts as below average academic standing on most transcripts. On a 4.3 scale, D+ is worth 1.33 instead of 1.3.
What Grade D+ Means on the Standard US Grading Scale
On the standard US grading scale used at most colleges and public high schools, grade D+ covers 67 to 69 percent and converts to a 1.3 grade-point value when the transcript is summarized on the 4.0 GPA scale. D+ is the top D tier; it earns course credit but typically does not satisfy major requirements at most US colleges.
Some US institutions adjust the percentage cutoffs by a few points: a school might publish an A floor of 90 instead of 93, or run a 7-point band for plus and minus tiers rather than the standard 3-point modifier shift. The 4.0 GPA value tied to grade D+ is more consistent across schools than the percentage range, so it's worth verifying the specific cutoff with the registrar's published grading policy before relying on either reading.
How Grade D+ Compares to Adjacent Letters
The plus and minus modifiers split each letter tier into three sub-bands worth 0.3 GPA points each. The table below shows how grade D+ sits relative to the letter directly above and below on the standard scale, with percentage range and 4.0 GPA value for each.
| Letter | Percentage | 4.0 GPA | Standing |
|---|---|---|---|
| C- | 70-72% | 1.7 | Average |
| D+ | 67-69% | 1.3 | Below average |
| D | 63-66% | 1.0 | Below average |
What GPA Is A D+ on the 4.0 Scale?
A D+ grade is worth 1.3 grade points on the standard 4.0 GPA scale used at most US colleges and high schools. On a 4.3 scale, D+ is worth 1.33 instead of 1.3. On a credit-weighted transcript, every D+ grade multiplies its course's credit hours by 1.3 to produce that course's contribution to the cumulative GPA total.
The arithmetic stays the same regardless of the course load: a D+ in a 3-credit class contributes 3.9 quality points; the same D+ in a 4-credit class contributes 5.2 quality points. Use the GPA calculator to model how a transcript with multiple D+ grades and other letters resolves to a final cumulative GPA on the 4.0 scale.
