How GPA is calculated
GPA (Grade Point Average) is a weighted average. Each course's letter grade converts to a number on the 4.0 scale, multiplied by the credit hours to produce quality points. Sum the quality points across all courses, divide by the total credit hours, and you have your GPA.
The formula: GPA = Σ(grade points × credit hours) ÷ Σ(credit hours). A 4-credit A is worth 16 quality points (4.0 × 4). A 3-credit B is worth 9 (3.0 × 3). The credit hours matter — a high grade in a 4-credit course moves your GPA more than the same grade in a 1-credit course.
The standard US 4.0 scale
| Letter grade | Percentage (typical) | Grade points |
|---|---|---|
| A+ | 97-100 | 4.0 |
| A | 93-96 | 4.0 |
| A− | 90-92 | 3.7 |
| B+ | 87-89 | 3.3 |
| B | 83-86 | 3.0 |
| B− | 80-82 | 2.7 |
| C+ | 77-79 | 2.3 |
| C | 73-76 | 2.0 |
| C− | 70-72 | 1.7 |
| D+ | 67-69 | 1.3 |
| D | 63-66 | 1.0 |
| D− | 60-62 | 0.7 |
| F | Below 60 | 0.0 |
Some schools use slightly different conversions — A+ sometimes counts as 4.3 (producing GPAs above 4.0 even unweighted), and percentage cutoffs vary. Check your school's official grading scale on the registrar's website.
Worked example
Five courses in one semester:
- Calculus I (4 credits, A): 4 × 4.0 = 16.0 quality points
- English Composition (3 credits, B+): 3 × 3.3 = 9.9
- Intro to Psychology (3 credits, A−): 3 × 3.7 = 11.1
- World History (3 credits, B): 3 × 3.0 = 9.0
- General Chemistry (4 credits, B+): 4 × 3.3 = 13.2
Total quality points: 59.2. Total credit hours: 17. GPA: 59.2 ÷ 17 = 3.48 (between B+ and A−).
If you replaced the B in World History with an A, you'd gain 3 quality points (3.0 → 4.0, multiplied by 3 credits = +3.0). New total: 62.2 ÷ 17 = 3.66. Small changes in individual grades, especially in high-credit courses, move the GPA more than people expect.
Common questions
How is GPA calculated?
GPA is the weighted average of your course grades, weighted by credit hours. Each letter grade is converted to a number (A=4.0, B=3.0, etc.), multiplied by the credit hours of that course to get 'quality points,' summed across all courses, and then divided by the total credit hours. The result is your GPA on a 4.0 scale.
What's the standard US 4.0 GPA scale?
Most US schools use: 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. Some schools count A+ as 4.3 instead of 4.0 (which can produce GPAs above 4.0 even unweighted), but most cap A+ at 4.0. This calculator uses the standard cap.
What's a good GPA?
Context dependent. For high schoolers: 3.5+ is competitive for selective colleges, 3.7+ for very selective, 3.9+ for highly selective like Ivies. For college students: 3.5+ keeps options open for grad school, 3.7+ for top programs and competitive jobs, 3.0+ is usually the minimum for honors societies and many internships. Below 2.0 typically triggers academic probation.
What's the difference between cumulative GPA and semester GPA?
Semester (or term) GPA includes only courses from one term. Cumulative GPA includes all courses you've ever taken at the institution. To calculate cumulative manually, you'd add up all quality points from every semester and divide by all credit hours ever attempted. Most schools track both — semester GPA matters for short-term standing (dean's list, probation), cumulative matters for graduation requirements and transcripts.
Do failed courses count in GPA?
Yes — an F counts as 0 quality points but the credit hours still count in the denominator, dragging your GPA down significantly. If you retake the course and pass, most schools either replace the F with the new grade in GPA calculation or average the two (policies vary). Always check your school's grade-replacement policy before retaking.
Do pass/fail courses count?
Usually no — pass/fail courses don't affect your GPA either way. A 'pass' typically counts as credit earned but with no quality points (excluded from GPA), and a 'fail' may or may not count against you depending on the school. Pass/fail is useful for taking risks in courses outside your strengths without GPA consequences, but doesn't help raise a low GPA.
Does my high school GPA affect college admissions?
Yes — it's typically the single most important factor in college admissions, more than test scores or essays. Colleges look at both unweighted GPA (raw academic performance) and weighted GPA (accounting for course difficulty). They also examine grade trends — an upward trajectory often matters more than a single number. Class rank, when reported, provides additional context about how your GPA compares to peers.
How do I raise my GPA quickly?
Math: it gets harder as you accumulate more credits. With 60 credits at a 3.0 GPA, getting all A's for the next 15 credits raises you to 3.2 — small move. The fastest paths: take additional courses to boost the credit-weighted average (heavier course loads with high grades), retake any courses where your school replaces grades, and prioritize getting high grades in remaining required courses over discretionary ones.
What's the difference between credits and credit hours?
They're typically interchangeable — both refer to the unit measure of how much a course counts. A 3-credit course usually meets 3 hours per week for a semester. Some schools use 'units' instead. Lab courses often have more credit hours than lecture-only courses. For GPA calculation, what matters is whatever number your transcript shows in the 'credits' column — that's the weight.
Why is my GPA different on different transcripts?
Schools calculate GPA differently. Major-specific GPA might exclude general education courses. Some institutions exclude transfer credits from GPA but count them toward graduation. Others use different scales (4.3 vs 4.0). Application services like AMCAS (medical school) and LSAC (law school) recalculate GPA using their own scales, often producing different numbers than your school's transcript. Always check which GPA a particular application is asking for.
