How GPA Is Calculated
GPA is calculated by converting each letter grade to grade points, multiplying by each course's credit hours, summing those totals, and dividing by the total number of credit hours. This calculator uses the standard unweighted US 4.0 scale.
Frequently Asked Questions
Does this use a standard grading scale?
Yes — the standard unweighted US 4.0 scale (A=4.0 through F=0.0). Some schools use a different or weighted
scale, so check with your institution if you need an exact match.
Guide: understanding your result
- GPA = Σ(grade points × credit hours) ÷ total credit hours. Courses with more credits weigh more.
- Most US colleges use a 4.0 scale; weighted high-school GPAs may add points for honors or AP courses.
- Pass/fail and withdrawn courses usually do not affect GPA; check your school's policy.
Worked example
A (3 credits), B+ (4 credits), A− (3 credits) and C (2 credits): (4.0×3 + 3.3×4 + 3.7×3 + 2.0×2) ÷ 12 = 40.3 ÷ 12 = 3.36.
Common 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 |
Some schools use different values (for example A+ = 4.3).
Common mistakes to avoid
- Averaging grade points without weighting by credits.
- Mixing weighted and unweighted GPAs when comparing.
Frequently asked questions
How can I raise my cumulative GPA?
High grades in courses with more credit hours have the largest effect; the more credits already completed, the slower the cumulative GPA moves.
