Cumulative GPA calculator
Add courses with letter grades and credits. We use a common unweighted 4.0 letter map (A = 4.0, A− = 3.7, …). Schools differ on plus/minus and repeats — treat this as a check, not the registrar.
Credit-weighted on a common 4.0 ± map.

When to use — and when not to
When to use
Rough cumulative after a term posts; comparing “if I get a B in this 4-credit class”; transfer planning ballpark.
When not to
Weighted high-school GPA with honors bumps — we do not model those. One class percent — course grade tools.
Assumptions
Standard 4.0 ± map. Credits weight the average. No retake / forgive policies.
How it works
GPA = Σ(grade_points × credits) / Σ(credits)
- Add each course letter and credit hours.
- Use the same scale your school publishes when you can.
- Read cumulative GPA.
Examples
A (3 cr), B (3 cr), B+ (4 cr)
≈ 3.30
add F (3 cr) to prior
GPA drops hard — credits still count unless forgiven
Gotchas
- A− / B+ values are not universal.
- Failed then retaken classes may be replaced — we do not auto-drop the old row.
- This site’s main job is course finals; GPA pages are helpers only.
