GPA Calculator
GPA =
44.1 quality points ÷ 14 credits
44.1 quality points ÷ 14 credits
Convert each letter grade to its US 4.0 scale points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiply by the credit hours, sum across all courses, and divide by total credits. The credit-weighted divide makes a 5-credit class count more than a 1-credit lab.
GPA = Σ(points × credits) / Σ(credits)
GPA — Grade Point Average — is a weighted average of your letter grades. Each letter is mapped to a number on the US 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0, with +/- modifiers adding or subtracting 0.3 or 0.4). Multiply each course's points by its credit hours to get quality points, sum all quality points, then divide by total credits. The credit weighting is what separates GPA from a simple letter average: a 4-credit A counts twice as much as a 2-credit A. Use this calculator for a single semester or, by entering every course you've taken, your cumulative GPA.
Find the semester GPA for a student who took four courses: English Composition (A, 4 credits), Calculus I (B+, 3 credits), History (B, 3 credits), and Biology (C+, 4 credits).
A GPA of 3.15 corresponds to a solid B (B average is 3.0; B+ is 3.3). Most graduate programs and competitive scholarships look for a 3.0 minimum, and dean's list typically begins at 3.5.
Three GPA distinctions trip people up most often. First, weighted vs unweighted: an unweighted GPA caps at 4.0 and treats every course the same; a weighted GPA can exceed 4.0 because Advanced Placement, International Baccalaureate, and Honors courses add a 0.5–1.0 bonus (so an A in an AP class can count as 5.0). This calculator uses the standard unweighted 4.0 scale. Second, semester vs cumulative: a semester GPA averages one term's courses; a cumulative GPA averages every course you've ever taken, weighted by credit. Add every course across all semesters to compute cumulative. Third, +/- modifiers: most US scales add 0.3 for + and subtract 0.3 for - (A− = 3.7, B+ = 3.3, etc.). Some institutions use unsigned grades only (just A, B, C, D, F), in which case ignore the +/- options.
Convert each letter grade to its 4.0-scale points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiply by the credit hours for that course to get quality points, sum the quality points across all courses, then divide by the sum of credit hours. The result is your credit-weighted grade point average.
GPA = Σ(points × credits) / Σ(credits). The numerator adds up grade-point × credit-hour products for every course; the denominator adds up just the credit hours. The +/- modifiers add or subtract 0.3 (so A− = 3.7, B+ = 3.3, B− = 2.7, etc.), and the result is on a 0.0–4.0 scale.
A 3.5 GPA sits halfway between a straight B (3.0) and a straight A (4.0). On a letter scale it corresponds to a mix of A's and B's — typically more A's than B's, weighted by credit. Most schools place 3.5 at the dean's-list threshold, and many scholarships require at least 3.5 to renew.
Add every course you've ever taken to the calculator — not just one semester — and let the credit-weighted divide handle the rest. Cumulative GPA = total quality points across all terms / total credits across all terms. You cannot simply average the individual semester GPAs unless every semester carried equal credits.
On the most widely used 4.0 scale, yes — both A+ and A map to 4.0 points, and the scale is capped at 4.0. Some schools use a 4.3 scale where A+ = 4.3, and weighted high-school scales can push A+ in AP courses to 5.0. Check your institution's official conversion table.
Unweighted GPA caps at 4.0 and treats every course equally on the standard 0.0–4.0 scale. Weighted GPA adds bonus points (typically 0.5 or 1.0) for honors, AP, or IB courses, so an A in an AP class can count as 5.0 and the overall GPA can exceed 4.0. This calculator uses the unweighted scale; if your transcript shows weighted grades, enter the unweighted letter you actually earned.
Most US colleges require a minimum cumulative GPA of 2.0 (a C average) to graduate. Many programs in nursing, engineering, or education require 2.5 or 3.0 within the major. Graduate programs typically require 3.0 to stay in good standing and complete the degree.
Usually no — withdrawals (W) and pass/fail (P/NP, S/U) grades typically don't affect GPA at all. They still count toward total credits attempted at some institutions, but they're excluded from the quality-points sum. Only enter courses with a real letter grade in this calculator.
Reference: US standard 4.0 grading scale as used by the College Board, NCES, and most American colleges and universities. +/- modifiers add or subtract 0.3 from the unsigned letter; A+ and A both map to 4.0 on the capped 4.0 scale.
Grade Point Average is the credit-weighted average of letter grades mapped onto the US 4.0 scale:
Where:
A 4.0 means straight A's; a 3.0 means a straight B average; 2.0 is a C average. Schools convert these averages back to descriptive tiers — dean's list typically starts at 3.5, cum laude around 3.7, and academic probation kicks in below 2.0.
First-Semester Freshman
A student takes English Composition (A, 4), Calculus I (B+, 3), History (B, 3), and Biology (C+, 4).
Semester GPA = 3.15 (B+ average).
Solid standing — above the 3.0 threshold for most scholarships and graduate-program minimums, just below dean's list.
Dean's List Honors
A junior takes five upper-division classes: Organic Chem (A, 4), Genetics (A−, 4), Statistics (A, 3), Philosophy (B+, 3), and Lab Methods (A, 1).
Semester GPA ≈ 3.78 — dean's list at most institutions.
Dean's list cutoffs vary: 3.5 is common, 3.7 is competitive, 3.85 is required at some Ivy-tier schools.
Recovery Semester
A student finished last term at 2.1 and now takes four classes: Stats (A, 3), Writing (B+, 3), Sociology (A−, 3), and Internship (A, 3).
Semester GPA = 3.75 — strong recovery.
To find the new cumulative, add these 12 credits and 45.0 quality points to the prior cumulative totals (not the prior GPA), then divide.
| Letter | Points | Typical % Range |
|---|---|---|
| A+ | 4.0 | 97–100 |
| A | 4.0 | 93–96 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C− | 1.7 | 70–72 |
| D+ | 1.3 | 67–69 |
| D | 1.0 | 63–66 |
| D− | 0.7 | 60–62 |
| F | 0.0 | Below 60 |
Percent ranges are typical US institutional cutoffs and vary by school. A and A+ both equal 4.0 on the standard capped scale; some institutions use a 4.3 scale where A+ = 4.3.
