| Letter Grade | GPA Points | Typical % Range | Quality Points (3-credit) |
|---|---|---|---|
| A+ | 4.0 (some schools 4.3) | 97–100% | 12.0 |
| A | 4.0 | 93–96% | 12.0 |
| A− | 3.7 | 90–92% | 11.1 |
| B+ | 3.3 | 87–89% | 9.9 |
| B | 3.0 | 83–86% | 9.0 |
| B− | 2.7 | 80–82% | 8.1 |
| C+ | 2.3 | 77–79% | 6.9 |
| C | 2.0 | 73–76% | 6.0 |
| C− | 1.7 | 70–72% | 5.1 |
| D+ | 1.3 | 67–69% | 3.9 |
| D | 1.0 | 63–66% | 3.0 |
| D− | 0.7 | 60–62% | 2.1 |
| F | 0.0 | Below 60% | 0.0 |
Note: percentage cutoffs vary by institution and professor. Some schools use 90/80/70/60 as letter grade breakpoints; others use 93/83/73/63. Always check your course syllabus for the exact scale used in that class.
Your GPA is calculated from quality points, not letter grades directly. Quality points = GPA value × credit hours. A B (3.0) in a 3-credit course earns 9.0 quality points. An A (4.0) in a 4-credit course earns 16.0 quality points. Your cumulative GPA = total quality points ÷ total credit hours attempted.
This is why a 4-credit course affects your GPA more than a 3-credit course. An A in a 4-credit course adds 16 quality points; an A in a 3-credit course adds 12. A C in a 4-credit course drops your GPA more than a C in a 3-credit course. High-credit courses in your schedule deserve proportionally more of your study time.
| GPA | Equivalent Grade | Significance |
|---|---|---|
| 4.0 | All A's | Perfect GPA; summa cum laude at most schools |
| 3.7+ | Mostly A's with occasional A− | Magna cum laude at most schools; highly competitive for graduate programs |
| 3.5+ | Mostly A's with some B+'s | Dean's list at most schools; competitive for most graduate programs |
| 3.0+ | B average | Most common scholarship GPA minimum; minimum for many graduate programs |
| 2.5+ | B− to C+ average | Minimum for some graduate programs and state scholarship renewals |
| 2.0+ | C average | Minimum to remain in good academic standing; below this risks academic probation |
The GPA impact of each grade depends on how many credits you have already completed. Early in college (under 45 credits), each grade has a large effect — an A in a 3-credit course when you have 15 credits completed adds 0.13 GPA points. Later (90+ credits), the same A adds only 0.02 GPA points. This is why front-loading strong grades early in college is the highest-leverage GPA strategy available to most students.
Not all schools use plus/minus grading. Some award only whole letter grades (A, B, C, D, F), where a B+ and a B− both simply record as B (3.0). Others use the full plus/minus scale shown in the chart above, where a B+ (3.3) and a B− (2.7) are treated as meaningfully different. If your school doesn't use plus/minus grades, ignore the finer breakpoints in this converter and round to the nearest whole letter.
A+ grades are also inconsistent across schools — some cap GPA at 4.0 even for A+ work, while others award 4.3. Check your registrar's academic policy or your syllabus to see which convention your institution follows before comparing your GPA to a national average or scholarship cutoff.
If your school reports raw percentages rather than letter grades, use the percentage column in the chart above to find your equivalent letter and GPA value. For example, an 85% typically falls in the B range (3.0), while a 91% typically falls in the A− range (3.7). Keep in mind that percentage cutoffs for each letter grade vary by school and even by individual professor, so this is an approximation — your syllabus grading scale is always the authoritative source.
Is a B+ the same as a 3.5 GPA? No. A B+ is typically 3.3 GPA points, not 3.5. A GPA of exactly 3.5 falls between a B+ (3.3) and an A− (3.7) and doesn't correspond to a single letter grade — it usually reflects a mix of A's and B's across your courses.
What letter grade is a 2.0 GPA? A 2.0 GPA corresponds to a C average. This is the minimum most colleges require to remain in good academic standing.
Does every college use the same 4.0 scale? Most US colleges use a 4.0 scale, but the exact point values for plus/minus grades (like A− or B+) can vary slightly between institutions. Weighted courses (AP, IB, Honors) may also use a 5.0 scale at the high school level. Always confirm with your specific school.
Can my GPA be higher than 4.0? Yes, if your school weights AP, IB, or Honors courses, or awards 4.3 for an A+. An unweighted GPA (like this converter uses) will always cap at 4.0.
How do I convert multiple grades at once into a GPA? This tool converts one grade at a time. To calculate a full GPA from multiple courses and credit hours, use the GPA Calculator instead.
What is 90 in GPA? A 90% typically converts to an A− (3.7 GPA) under the common 90–92% = A− breakpoint used by most US schools. Some schools set the A cutoff at 90 instead of 93, in which case 90% would be a straight A (4.0). Check your syllabus for the exact breakpoint your class uses.
What grade is 87 in GPA? An 87% typically converts to a B+ (3.3 GPA) under the common 87–89% = B+ breakpoint. Some schools set the B+ cutoff differently (e.g. 85 or 88), so this is an approximation — confirm your school's exact grading scale.
What is a 95 or 97 in GPA? A 95% or 97% both typically fall in the A range and convert to a 4.0 GPA under the standard 93–100% = A scale (some schools award 4.3 for A+ starting at 97%). Both scores represent top-tier academic performance regardless of the exact point value your school assigns.
What letter grade is a B (3.0 GPA) equal to in percentage? A B (3.0 GPA) typically corresponds to an 83–86% range under the standard US grading scale. A straight B− (2.7) is usually 80–82%, and a B+ (3.3) is usually 87–89%.
