About GPA Calculator
Use the GPA Calculator to compute your credit-weighted GPA from your courses in seconds. Add your courses, enter credits and letter grades, and get your GPA instantly.
What this calculator includes
- Credit weighting: a 4‑credit class counts more than a 2‑credit class.
- Unweighted GPA: uses the base letter‑grade scale.
- Weighted GPA mode: optional weighting (for honours/AP/IB) with a configurable cap.
If your school uses a different mapping or policy, you can still use this as a consistent way to model scenarios (for example, “what happens if I improve one course by a letter grade?”).
Frequently asked questions
Convert each course grade to grade points (e.g. A = 4.0), multiply by the course credits, add them up, then divide by total credits. This calculator does the credit-weighted average instantly.
Unweighted GPA uses the base scale (often 0–4.0). Weighted GPA adds extra points for certain courses (commonly honours/AP/IB) based on your school's rules. Because policies vary, this tool lets you toggle weighting and choose a GPA cap.
No. Some schools cap weighted GPA at 4.5 or 5.0, and some use different grade-point mappings. Use the cap control for your system and treat the result as a consistent estimate for comparing scenarios.
