GPA Calculator
Calculate your unweighted GPA from course grades and credit hours, on the standard U.S. 4.0 scale.
What is GPA Calculator?
The GPA calculator computes your grade point average on the U.S. 4.0 scale, the standard used by almost all American high schools and colleges. Just enter each course's credit hours and letter grade — the calculator does the credit-weighted math.
A 3.0 is a solid B average. 3.5+ is considered "honors" and opens most top graduate programs. 3.7+ is competitive for Ivy League and top law/med schools.
Formula
GPA = Σ(grade points × credits) ÷ Σ credits
Grade-to-points mapping (standard U.S. unweighted scale):
- A+ / 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
Worked example
Five courses: 3cr A, 4cr B+, 3cr A−, 3cr B, 2cr A.
- Points = 3(4.0) + 4(3.3) + 3(3.7) + 3(3.0) + 2(4.0) = 12 + 13.2 + 11.1 + 9 + 8 = 53.3
- Credits = 3 + 4 + 3 + 3 + 2 = 15
- GPA = 53.3 / 15 ≈ 3.55
How to use this calculator
- For each course, write one line with the credits and grade, separated by a comma. Example:
3, A- - Paste in all courses for the term (or your full transcript).
- GPA updates instantly.
Use A+ = 4.0 by default. Some schools award 4.3 for A+ — if yours does, count each A+ as two "A" entries or override manually.
Frequently asked questions
What is a good college GPA?
3.0 (B) is the floor for most graduate programs. 3.5 is competitive for jobs. 3.7+ is excellent and puts you in range for top grad school, most prestigious fellowships, and Latin honors (cum laude, magna cum laude) depending on school policy.
What is a weighted vs unweighted GPA?
This calculator is unweighted — every course counts the same per credit hour. Many U.S. high schools use a weighted scale that boosts AP/IB/honors courses by 0.5–1.0 points (so an A in AP Calculus = 5.0). Colleges usually recompute your GPA themselves on their own scale.
How do I raise my GPA?
GPA becomes harder to move as you accumulate credits — each new term carries less weight. Early-career: focus on As in 3-credit courses. Later: retake any D/F courses if your school allows grade replacement. Consider course load — one solid A is worth more than two Bs.
Are pass/fail or withdrawn courses counted?
No — pass/fail, W, and audit courses are not included in GPA. Only letter-graded courses factor in. This is consistent with how registrars calculate GPA on your transcript.
