Complete letter grade to GPA points table
This table covers every letter grade from A+ through F on the standard 4.0 scale, with the corresponding percentage ranges typically used and the quality points each grade contributes per credit hour.
| Letter Grade | Grade Points (4.0 scale) | Typical % Range | Classification |
|---|---|---|---|
| A+ | 4.0 (or 4.3 at some schools) | 97–100% | Excellent |
| A | 4.0 | 93–96% | Excellent |
| A− | 3.7 | 90–92% | Excellent |
| B+ | 3.3 | 87–89% | Above Average |
| B | 3.0 | 83–86% | Above Average |
| B− | 2.7 | 80–82% | Above Average |
| C+ | 2.3 | 77–79% | Average |
| C | 2.0 | 73–76% | Average |
| C− | 1.7 | 70–72% | Average |
| D+ | 1.3 | 67–69% | Below Average |
| D | 1.0 | 63–66% | Below Average |
| D− | 0.7 | 60–62% | Below Average / Marginal |
| F | 0.0 | Below 60% | Failing |
The grade points shown here (A=4.0, A−=3.7, B+=3.3, and so on) are the values used by the large majority of U.S. colleges and universities. They derive from the system published by the American Association of Collegiate Registrars and Admissions Officers (AACRAO) and adopted widely since the mid-20th century. Variations exist — covered in the institutional variation section below — but this table represents what most transcripts follow.
How GPA is calculated from grade points
Grade point values exist to enable GPA calculation. The calculation follows the same weighted average formula used for any credit-hour-weighted mean.
The formula
GPA = Total Quality Points ÷ Total Credit Hours
Where: Quality Points = Grade Points × Credit Hours for each course
Worked example
A student completes three courses in a semester:
| Course | Credits | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| English Composition | 3 | A− | 3.7 | 11.1 |
| Calculus I | 4 | B+ | 3.3 | 13.2 |
| History Survey | 3 | B | 3.0 | 9.0 |
| Totals | 10 | — | — | 33.3 |
GPA = 33.3 ÷ 10 = 3.33
The credit hours act as weights — a 4-credit course has more influence on GPA than a 3-credit course because it contributes more to both the numerator (quality points) and denominator (total credits). This is why a low grade in a high-credit course — like a lab-heavy science — has an outsized negative impact, and why bringing up a GPA requires focusing on high-credit courses where possible.
For calculating GPA yourself, the GPA calculator handles this automatically and shows quality points for each course. The cumulative GPA calculator lets you combine new semester grades with an existing GPA to see your running total.
Grade-by-grade breakdown
A grades: A+, A, A−
The A range (3.7–4.0 grade points) covers excellent academic performance. All three A grades place a student in the top tier of academic standing, qualify for Dean's List designation at most schools, and meet the GPA thresholds for competitive graduate programs and merit scholarships.
A+ (4.0 or 4.3): The highest letter grade designation. At most schools, A+ carries the same 4.0 grade points as a plain A and doesn't raise GPA above 4.0. Where schools do assign 4.3 to A+, a student earning straight A+ grades would have a GPA slightly above 4.0. The A+ is the rarest grade and typically requires exceptional performance — scoring in the top few percentage points of the class or achieving near-perfect marks on all assessments.
A (4.0): The benchmark of excellent work on the standard scale. A consistent record of A grades produces a 4.0 GPA. Most professors assign A to the 93–96% range, though grading scales vary. A grades are required for many Dean's List designations and are the standard for many graduate school honor requirements.
A− (3.7): A− marks the transition between the A and B ranges. It carries 3.7 points, which means a semester of straight A− grades produces a 3.7 GPA — strong enough for most graduate school thresholds and most merit scholarship eligibility but below the 4.0 mark. In professor grading, A− typically means the work was excellent but missed the highest designation by a modest margin.
B grades: B+, B, B−
The B range (2.7–3.3 grade points) is the most common grade distribution region for college students. B grades represent above-average to solid performance and are the grades that most frequently determine cumulative GPA outcomes for undergraduates.
B+ (3.3): B+ is a strong grade that places a student meaningfully above the 3.0 line. A semester of B+ grades produces a 3.3 GPA. Many competitive merit scholarship programs set their eligibility threshold at 3.0 or 3.25, which a consistent B+ record comfortably meets. In professor grading, B+ work is well-organized, demonstrates understanding of the material, and shows engagement beyond the minimum.
B (3.0): The plain B is the threshold grade in many academic contexts. Many graduate programs set a minimum 3.0 GPA for admission or continued enrollment. Many merit scholarships require maintaining 3.0. Academic standing requirements at most institutions consider 2.0 the minimum, but graduate assistantships and specialized programs often require 3.0 as the floor. A student earning all B grades through their degree completes with a 3.0 cumulative GPA.
B− (2.7): B− sits between the B and C ranges and produces a 2.7 average when earned consistently. It's above average work that doesn't quite reach the clean 3.0 threshold. Students near graduate school application time who have B− grades in several courses may find themselves below the 3.0 admissions minimum — worth checking before senior year if graduate school is a goal.
C grades: C+, C, C−
The C range (1.7–2.3 grade points) represents average performance. C grades are passing grades and count as satisfactory completion of coursework in most cases, but they carry implications for GPA, for meeting prerequisites in sequential courses, and for financial aid standing.
C+ (2.3): C+ represents performance that's above average within the C band but below the B range. At 2.3 grade points, C+ grades are solidly passing and don't threaten academic standing (which is typically maintained at 2.0), but accumulating C+ grades makes it difficult to build a GPA much above 2.5 without offsetting B or better performance in other courses.
C (2.0): The plain C is the academic standing threshold grade at most institutions. A cumulative GPA that falls below 2.0 typically triggers academic probation. The 2.0 minimum requirement exists at most institutions for: maintaining undergraduate enrollment in good standing, eligibility for most financial aid, and meeting minimum major GPA requirements. A student with a 2.0 cumulative GPA is meeting the minimum floor — not building toward graduate school or selective employment, but maintaining standing.
C− (1.7): C− is a passing grade at the university level in most respects, but it may not satisfy course prerequisites in sequences that require a C or better. Some courses — particularly in sciences, mathematics, and nursing — require a C (not C−) as the minimum grade to continue to the next course in the sequence. Check your program's prerequisite requirements; a C− in a gateway course can require retaking it before advancing.
D grades: D+, D, D−
D grades (0.7–1.3 grade points) are technically passing at many institutions but carry significant implications. They lower GPA substantially, often don't transfer as credit to other institutions, and may not satisfy prerequisite requirements.
D+ (1.3): D+ grades are below average performance. The credit hours count toward total credit earned and the 1.3 grade points enter the GPA calculation, but a pattern of D+ grades will keep cumulative GPA near or below 2.0. Many four-year programs require students in major courses to earn at least a C; a D+ in a required course may mean retaking it even though it counts as passed on the transcript.
D (1.0): A D grade represents minimum passing performance on the 4.0 scale. The credit counts, but the impact on GPA is significant — a D in a 3-credit course contributes 3.0 quality points, the same as a C in a 1-credit course. For transfer students, D grades often do not transfer; community colleges and universities typically transfer only C or better credits to four-year institutions.
D− (0.7): D− is the lowest passing grade in most grading systems. At some institutions, D− is treated as a failing grade for credit purposes even though it appears as "D−" on the transcript rather than "F". At others, it's technically passing but functionally unusable — 0.7 quality points per credit hour, which substantially reduces any weighted average it enters. Check your institution's specific policy on D− grades and credit.
F grade: 0.0 grade points
F (0.0): A failing grade earns zero grade points. The course's credit hours are included in the denominator of the GPA calculation but contribute nothing to the numerator. An F in a high-credit course can dramatically lower GPA — a single F in a 4-credit course among otherwise B grades produces a meaningful GPA drop, because the course contributes 0 quality points against 4 credit hours in the denominator.
Most colleges offer policies that can mitigate the GPA impact of an F: academic renewal or grade forgiveness, which replaces the F in GPA calculations upon successful retaking of the course (though the original F typically remains on the transcript); W (Withdrawal) instead of F if the course is dropped before the withdrawal deadline; and Incomplete (I) grades where the work is finished in a subsequent term.
The A+ question: 4.0 or 4.3?
The treatment of A+ is the most variable aspect of U.S. college grading scales. Institutions fall into two camps:
Camp 1: A+ = 4.0 (most common)
The majority of U.S. colleges and universities, including most large state universities and liberal arts colleges, cap A+ at 4.0. In this system, earning an A+ on a transcript is a distinction — it signals exceptional work — but it doesn't raise GPA above 4.0 because the grade point ceiling is 4.0. The practical result is that a student who earns all A grades and a student who earns all A+ grades have the same 4.0 GPA.
Camp 2: A+ = 4.3 (less common)
Some institutions, including several Ivy League and highly selective universities, assign A+ a value of 4.3. Under this system, earning A+ grades raises GPA above 4.0, and a student who consistently earns A+ grades can achieve a GPA like 4.1 or 4.2. The reported "GPA" in these cases is on an implicit scale that runs slightly above 4.0, which can create confusion when comparing GPAs across institutions.
Why it matters
The A+ convention matters most when comparing GPAs across institutions or when applying to graduate programs. A 4.0 from a school where A+ = 4.0 and a 4.2 from a school where A+ = 4.3 represent different underlying performance levels but different reported numbers. Graduate admissions and scholarship committees at selective programs are generally aware of institutional scale differences; some explicitly request or use standardized evaluations rather than raw GPA for this reason.
How grading scales vary by institution
The table at the top of this guide reflects the most common grade point values used across U.S. higher education. But these aren't federally standardized — each institution sets its own grading policy. Common variations include:
Whether plus/minus grading is used at all
Some institutions don't use plus/minus modifiers. Under a simplified scale, the only grades are A (4.0), B (3.0), C (2.0), D (1.0), and F (0.0). An A− and an A both map to 4.0; a B+ and a B− both map to 3.0. This is more common at community colleges and some smaller institutions. Students from no-modifier schools will have GPAs calculated from these round-number values, which compresses the distribution of GPA outcomes.
Percentage cutoffs for each grade
The percentage ranges in the table above (A = 93–96%, B = 83–86%, etc.) are the most commonly used but not universal. Some instructors use 90% as the A cutoff rather than 93%. Some courses use 95% as the A threshold. Graduate courses sometimes use 80% as the B/A boundary. These are instructor-level and department-level decisions that don't affect the grade point scale but do affect which letter grade a given percentage produces.
Whether D grades count as passing
The treatment of D varies more than any other passing grade. Some institutions define D grades as passing for credit purposes but require C or better to satisfy major requirements or graduation requirements. Others define D as unsatisfactory for all major courses and require retaking the course. A few treat D and D− differently from each other — D as passing, D− as effectively failing.
WF, FN, and other specialized failing grades
Beyond F, some institutions use WF (Withdrawn Failing — grade of F assigned when a student stops attending without withdrawing), FN (Failure to participate after last date of attendance), or XF (academic integrity violation). These variants all calculate as 0.0 grade points in GPA, and their presence on a transcript signals circumstances beyond poor performance.
Weighted and extended scales (4.3 and 5.0)
Two extended grading scales appear outside the standard college 4.0 context:
The 4.3 extended scale
When A+ = 4.3, the effective scale runs from 0.0 to 4.3. Every other grade point stays identical — A = 4.0, A− = 3.7, B+ = 3.3, and so on. Only the ceiling changes. This scale is used by the minority of colleges and universities that award A+ an above-4.0 value, and by some high schools. On this scale, a "perfect" GPA (all A+) would be 4.3, but the national college standard still treats 4.0 as the benchmark.
The 5.0 weighted scale (high school)
The 5.0 scale is used almost exclusively in high school for weighted GPA — a system that assigns higher grade points to honors and AP (Advanced Placement) courses to reflect their greater difficulty. Under a typical weighted scale:
| Grade | Standard Course (4.0) | Honors Course (4.5) | AP Course (5.0) |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
On the 5.0 scale, a student earning A grades in all AP courses would have a 5.0 weighted GPA. This makes weighted high school GPAs incomparable to standard 4.0 GPAs — a 4.2 weighted GPA doesn't mean the same thing as a 4.2 on a standard scale. For college admission, most institutions recalculate applicants' GPA on their own unweighted 4.0 scale from the transcript, making the original weighted GPA less relevant than it might appear.
The guide on weighted vs. unweighted GPA: which one matters for college covers this distinction in detail.
Percentage equivalents by letter grade
The percentage ranges below are the most common cutoffs used across U.S. colleges and universities. These vary by instructor and institution — treat them as typical values, not universal ones.
| Letter Grade | Grade Points | Typical % Range | Common Descriptor |
|---|---|---|---|
| A+ | 4.0 / 4.3 | 97–100% | Exceptional |
| A | 4.0 | 93–96% | Excellent |
| A− | 3.7 | 90–92% | Excellent |
| B+ | 3.3 | 87–89% | Very Good |
| B | 3.0 | 83–86% | Good |
| B− | 2.7 | 80–82% | Good |
| C+ | 2.3 | 77–79% | Average |
| C | 2.0 | 73–76% | Average |
| C− | 1.7 | 70–72% | Average |
| D+ | 1.3 | 67–69% | Below Average |
| D | 1.0 | 63–66% | Poor |
| D− | 0.7 | 60–62% | Poor |
| F | 0.0 | Below 60% | Failing |

Key GPA thresholds and what they mean
Certain GPA values carry real-world implications for academic standing, eligibility, and opportunities. Understanding what these thresholds mean helps put grade point values in context:
4.0 — Perfect GPA on the standard scale
A 4.0 GPA means earning A grades (or A+ where A+ = 4.0) in every course. It's the maximum possible GPA on the standard scale and represents consistent excellent performance across all subjects. Valedictorian recognition, many competitive fellowships, and some scholarship renewals specifically require maintaining a 4.0.
3.7 — Summa cum laude threshold at many schools
The 3.7 GPA is a common threshold for summa cum laude Latin honors designation. It represents the consistent A/A− performance level and is competitive for most graduate school programs. A 3.7 is produced by consistent A− grades — it takes consistent A− to get to 3.7, and any B grades require A+ or A in other courses to compensate.
3.5 — Strong academic record; common scholarship threshold
The 3.5 GPA is the threshold for many merit scholarships, including some state merit aid programs and departmental honors. It falls between B+ (3.3) and A− (3.7) and represents strong above-average academic performance. Many Dean's List designations require 3.5 per semester.
3.0 — Good academic standing; graduate school floor
The 3.0 GPA is the most common minimum for graduate school admission and for maintaining graduate student academic standing. Many undergraduate departmental honor societies and professional school applications use 3.0 as the competitive minimum. It represents consistent B performance.
2.5 — Common scholarship renewal minimum
A 2.5 GPA is a common institutional threshold — often the cutoff for merit aid renewal, for maintaining athletic eligibility in NCAA Division I, and for eligibility in co-curricular programs. It sits between C+ (2.3) and B− (2.7) territory.
2.0 — Academic standing minimum
The 2.0 GPA is the nearly universal minimum for undergraduate academic good standing. Falling below 2.0 triggers academic probation at most institutions, which can affect financial aid eligibility, enrollment, and access to certain programs. A 2.0 represents straight C performance. For more on what happens below this line, see the guide on what is academic probation and how GPA gets you there.
SAP minimums (for financial aid)
Federal financial aid Satisfactory Academic Progress (SAP) requirements mandate maintaining a minimum 2.0 cumulative GPA alongside meeting a completion rate and maximum timeframe standard. Falling below the SAP GPA minimum results in financial aid suspension, not just academic probation. The guide on what is satisfactory academic progress (SAP) and how GPA affects financial aid covers this fully.
Non-letter grades: P/F, I, W, and how they affect GPA
Not every grade on a transcript is a letter grade. Several designations appear on college transcripts without a grade point value — and they handle GPA differently:
P (Pass) and F (Fail) — Pass/Fail grading
Many courses offer a Pass/Fail grading option, and some courses are graded Pass/Fail by default. A P grade doesn't carry a grade point value and typically doesn't enter the GPA calculation — it counts for credit but doesn't affect GPA either positively or negatively. A Fail in a pass/fail course, however, does count as an F (0.0) in the GPA calculation at many institutions. Check your institution's policy on this; the treatment of Pass/Fail Failure grades varies.
I (Incomplete)
An Incomplete grade is assigned when a student has extenuating circumstances and needs additional time to complete coursework. The I holds the place of a grade and typically converts to an F if not resolved within a defined period (usually the next semester). While I is pending, it typically doesn't enter the GPA calculation — neither helping nor hurting. When the work is completed and a letter grade is assigned, that grade replaces the I in the GPA calculation.
W (Withdrawal)
A W grade is assigned when a student withdraws from a course after the add/drop period but before the withdrawal deadline. A W carries no grade points and does not affect GPA — it simply records that the student was enrolled and then withdrew. However, multiple W grades can raise questions in transcript review, and they do affect the completion rate component of Satisfactory Academic Progress (SAP) calculations for financial aid purposes.
AU (Audit)
An audited course is attended without receiving credit or a grade. AU appears on the transcript but contributes nothing to GPA or credit hour totals.
Individual letter grade reference pages
Each letter grade has a dedicated reference page covering grade point value, what the grade means in different contexts, comparison with adjacent grades, and what that grade implies for GPA over a full academic record:
- A+ GPA — grade point value, whether A+ raises GPA above 4.0, institutional variation
- A GPA — the 4.0 standard, Dean's List implications, graduate school context
- A− GPA — 3.7 grade points, difference from A, impact on cumulative GPA
- B+ GPA — 3.3 grade points, what a B+ record produces cumulatively
- B GPA — 3.0 grade points, the graduate school threshold grade
- B− GPA — 2.7 grade points, proximity to the 3.0 line
- C+ GPA — 2.3 grade points, academic standing considerations
- C GPA — 2.0 grade points, minimum standing threshold
- C− GPA — 1.7 grade points, prerequisite complications, transfer implications
- D+ GPA — 1.3 grade points, passing but problematic
- D GPA — 1.0 grade points, transfer complications, major requirements
- D− GPA — 0.7 grade points, institutional variation on whether this is passing
- F GPA — 0.0 grade points, GPA impact, grade forgiveness options
Frequently asked questions
What is a GPA point for each letter grade?
On the standard 4.0 scale: A+ = 4.0 (some schools 4.3), A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7, F = 0.0. These are the values used by the large majority of U.S. colleges and universities.
Is an A+ worth more than an A in GPA?
At most schools, no. The majority of U.S. colleges cap A+ at 4.0 — the same as a plain A. At a smaller group of institutions, A+ = 4.3, which does raise GPA above 4.0. Check your school's grading scale policy; both are common.
How do I calculate my GPA from letter grades?
Convert each letter grade to its grade point value. Multiply each value by the course's credit hours to get quality points. Add all quality points; add all credit hours. Divide quality points by credit hours. The result is your GPA. Example: B+ in 3 credits (9.9 QP) + A in 4 credits (16.0 QP) + C in 2 credits (4.0 QP) = 29.9 QP ÷ 9 credits = 3.32 GPA.
What GPA point is a C grade?
A C = 2.0 grade points. C+ = 2.3, C− = 1.7. A 2.0 GPA (all C grades) is the minimum for academic good standing at most institutions. Falling below 2.0 typically triggers academic probation.
Does an F affect GPA?
Yes. An F = 0.0 grade points. The course's credit hours are included in the GPA denominator but contribute zero quality points to the numerator. An F in a high-credit course has an outsized negative impact. Grade forgiveness or academic renewal policies at some institutions can replace the F in GPA calculations when the course is retaken, though the original F remains on the transcript.
What is a 3.5 GPA in letter grade?
A 3.5 GPA falls between B+ (3.3) and A− (3.7). It reflects consistent high-B / low-A performance — mostly B+ grades with some A grades, or consistent A− with some B+ mixed in. A 3.5 is considered a strong academic record and meets most merit scholarship and honor society thresholds.
What is the difference between a 4.0 scale and a 5.0 scale?
The 4.0 scale is the U.S. standard for college GPA. The 5.0 scale is a high school weighted GPA convention where AP and honors courses receive extra grade points (A in AP = 5.0 rather than 4.0). College admissions offices typically recalculate applicants' GPA on an unweighted 4.0 scale. All college GPA calculations use the 4.0 standard.
What percentage corresponds to each letter grade?
Typical ranges: A+ (97–100%), A (93–96%), A− (90–92%), B+ (87–89%), B (83–86%), B− (80–82%), C+ (77–79%), C (73–76%), C− (70–72%), D+ (67–69%), D (63–66%), D− (60–62%), F (below 60%). These vary by instructor and institution — they're the most common cutoffs, not universal ones.
