GPA Calculator
A GPA calculator computes your grade point average from the grades and credit hours of your courses. In the United States, the standard 4.0 scale assigns A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0, with plus and minus modifiers adding or subtracting roughly 0.3 points. Because courses carry different credit weights, a weighted average gives a far more accurate picture of academic performance than simply averaging grades.
Your GPA matters for scholarship eligibility, admission to graduate programs, academic honors such as cum laude distinctions, and even some job applications. Many universities require a minimum GPA of 2.0 to remain in good standing and 3.5 or higher for honors. Calculating it yourself lets you plan which grades you need in upcoming courses to reach a target average before official transcripts are released.
How it works
GPA is a credit-weighted average: each course grade is converted to grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiplied by that course's credit hours, and the products are summed. That total is then divided by the total credit hours attempted: GPA = Σ(grade points × credits) ÷ Σ(credits). A 3-credit A and a 1-credit C therefore yield (4.0×3 + 2.0×1) ÷ 4 = 3.5.
Use cases
- Checking whether your semester GPA meets a scholarship's minimum requirement
- Projecting the grades needed in remaining courses to reach a target cumulative GPA
- Converting numeric grades (0-10 or 0-100 scales) into a 4.0-scale GPA for US applications
- Verifying honor roll or dean's list eligibility before official grades are posted
Frequently asked questions
How do I calculate my GPA on a 4.0 scale?
Convert each letter grade to points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiply each by the course's credit hours, add up all the products, and divide by the total credits. For example, an A in a 3-credit course and a B in a 4-credit course gives (12 + 12) ÷ 7 ≈ 3.43.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the standard 4.0 maximum for every course. A weighted GPA gives extra points for harder classes — many US high schools award up to 5.0 for AP or IB courses and 4.5 for honors courses. Colleges often recalculate both when reviewing applications.
What GPA do I need for a scholarship or honors?
Requirements vary, but many scholarships require a minimum 3.0 GPA, and academic honors typically start around 3.5. Latin honors at US universities commonly require roughly 3.5 for cum laude, 3.7 for magna cum laude, and 3.9 for summa cum laude, though each institution sets its own thresholds.
How do I convert a 0-100 grade average to GPA?
There is no single official conversion, but a common mapping is 93-100 = 4.0 (A), 90-92 = 3.7 (A-), 87-89 = 3.3 (B+), 83-86 = 3.0 (B), and so on down the scale. If you are applying abroad, check whether the institution requires an official credential evaluation such as WES instead of a self-converted GPA.
Do pass/fail courses count toward my GPA?
Usually not. A passing grade in a pass/fail course earns the credits but is excluded from the GPA calculation, while a failing grade often still counts as 0.0 and lowers the average. Policies differ by institution, so check your school's academic catalog.
