How GPA math works
Every letter grade has a point value on the 4.0 scale. Each course contributes its points multiplied by its credit hours — so a 4-credit A pulls your average up harder than a 1-credit A. The calculator does the weighting for you:
GPA = Σ (grade points × credits) ÷ Σ credits
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 · F = 0
The 4.0 scale
| Letter | Points | Letter | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B− | 2.7 | D | 1.0 |
| F | 0.0 |
Reading your number honestly
- 3.7+ — honors territory; keep doing what you're doing.
- 3.3–3.7 — strong; competitive for most scholarships and programs.
- 3.0–3.3 — solid; a good semester can move you up a bracket.
- Below 3.0 — recoverable; high-credit courses and retakes are your levers.
One honest note admissions officers repeat: an upward trend beats a flat high number. A 3.2 that used to be a 2.6 tells a stronger story than a 3.4 that never moved.
Sources, assumptions and limitations
- Formula: GPA = Σ(grade points × credits) ÷ Σ credits
- Assumptions: The 4.0 letter scale shown is the common US convention; every course counts with its credit weight.
- Not included: Plus/minus policy differences, pass/fail courses, repeat-and-replace rules — your registrar's policy is the final word.

Frequently asked questions
How is GPA calculated?
Each letter grade converts to points on the 4.0 scale (A = 4.0, B = 3.0, and so on). Multiply each course's points by its credit hours, add everything up, and divide by the total credits: GPA = total grade points ÷ total credits.
What is a good GPA?
Above 3.0 is solid, 3.5+ is strong for most scholarships and grad programs, and 3.7+ puts you in honors territory. But trends matter too — an upward curve tells a better story than a flat number.
Do A+ and A count the same?
At most US schools both equal 4.0, and that is the convention this calculator uses. Some institutions award 4.3 for an A+ — check your school's official scale if it matters for your case.
What is the difference between weighted and unweighted GPA?
Unweighted GPA (this calculator) caps at 4.0 regardless of course difficulty. Weighted GPA gives bonus points for honors/AP/IB classes, often on a 5.0 scale. Colleges usually look at both, plus your transcript.
How can I raise my GPA?
Credits are leverage: a high grade in a 4-credit course moves your GPA more than in a 1-credit one. Retaking a failed course (where your school replaces the grade) is usually the fastest single fix.
