What this calculator does
It computes weighted GPA on a 4.0 scale based on your course credits and letter grades.
How GPA is calculated
Weighted GPA = Σ(grade points × credits) / Σ(credits). Use your school’s grade point mapping if it differs.
Who should use this
- Students tracking academic performance
- Advisors reviewing degree progress
Examples
- Courses: A(3cr), B+(4cr), B(3cr) → GPA ≈ 3.43
- Adding an A in a 1‑credit seminar shifts GPA slightly up
Understanding GPA
How Weighted GPA Works
Weighted GPA gives extra points for advanced courses like AP, IB, or honors classes. This allows students taking challenging courses to achieve GPAs above 4.0.
Common weighting systems:
- Standard courses: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0
- Honors/Pre-AP: A=4.5, B=3.5, C=2.5, D=1.5, F=0.0
- AP/IB: A=5.0, B=4.0, C=3.0, D=2.0, F=0.0
Weighted GPA = Σ(grade points × credits) / Σ(credits), where grade points reflect course difficulty.
GPA Scales Explained
4.0 Scale (Unweighted): Most common scale where A=4.0, B=3.0, C=2.0, D=1.0, F=0.0. Maximum is 4.0.
5.0 Scale (Weighted): Allows GPAs above 4.0 for advanced courses. AP/IB courses can earn up to 5.0 points per credit.
Other Scales: Some schools use 100-point scales, letter grades, or percentage-based systems. Always check your school's specific scale.
