For high school students
Most US high schools report GPA on the 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0). Add each class with its letter grade and credit value — a full-year course is usually 1 credit, a semester course 0.5 — and the dial shows your GPA and class-honor standing.
How your GPA is calculated
Each grade becomes grade points, multiplied by the course's credit, summed, and divided by total credits:
GPA = Σ(grade points × credits) ÷ Σ(credits)
Many high schools use plus/minus grades too (A− = 3.7, B+ = 3.3), which this calculator supports.
Worked example
A typical year of five full-credit courses:
- English — A (4.0)
- Algebra II — B+ (3.3)
- Biology — A− (3.7)
- World History — B (3.0)
- Spanish — A (4.0)
With each course worth 1 credit, GPA = (4.0 + 3.3 + 3.7 + 3.0 + 4.0) ÷ 5 = 18.0 ÷ 5 = 3.60.
Common mistakes to avoid
- Mixing weighted and unweighted grades. If you take AP or honors classes, decide whether you want a weighted GPA — use the weighted GPA calculator for that.
- Counting semester courses as full credits. A one-semester class is usually 0.5 credit.
- Including non-graded courses like pass/fail electives, which typically don't affect GPA.
Frequently asked questions
What's a good high school GPA?
On the unweighted 4.0 scale, 3.5+ is strong and competitive for many universities, 3.0–3.5 is solid, and 4.0 is a perfect record. Selective colleges often look for 3.7+ alongside rigorous coursework.
Should I calculate weighted or unweighted GPA?
Start with unweighted — it's what many colleges recalculate to. If you take AP, IB, or honors classes and want credit for that rigor, also compute a weighted GPA.
How many credits is a high school class?
A year-long course is typically 1 credit and a single-semester course 0.5. Some schools use different values — check your transcript so the weighting is right.
Does freshman year count toward my GPA?
Yes — cumulative high school GPA usually includes all four years. Some colleges weight later years more heavily, but freshman grades still appear on your transcript and in your cumulative average.
