How this GPA calculator works
GPA converts letter grades to a 4.0 scale, multiplies each by credit hours, then divides by total credits. Classes with more credits move the average more.
- A / A- = 4.0 / 3.7 · B+ / B / B- = 3.3 / 3.0 / 2.7
- C+ / C / C- = 2.3 / 2.0 / 1.7 · D+ / D / F = 1.3 / 1.0 / 0.0
This tool uses a common unweighted letter map. If your school weights AP/IB courses (for example A = 5.0), adjust manually or confirm against your transcript. For admissions context, read the college admissions GPA guide. For one class average or a final exam target, use the grade calculator.
