What's the difference between semester and cumulative GPA?

Add only the current term's courses for semester GPA, or every course you've taken for cumulative GPA — the formula itself doesn't change.

Can I add or remove courses?

Yes — use "Add course" for a new row, and the trash icon to remove one; the GPA recalculates instantly.

How are letter grades converted to points?

Using the common 4.0-scale mapping (A/A+ = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0.0) — the same scale used by most U.S. undergraduate institutions.

Does a course with 0 credits affect my GPA?

No — credits act as the weight in the calculation, so a 0-credit course contributes nothing to the weighted average regardless of its grade.

How do I calculate what GPA I need next term to reach a target cumulative GPA?

Add your completed courses as usual, then add a hypothetical course with your remaining planned credits and experiment with its grade until the cumulative GPA reaches your target.

Does this handle a pass/fail or audit course?

Not directly — pass/fail courses typically don't count toward GPA at most schools, so leave them out of the list rather than assigning them a letter grade.

Why does one A+ not always mean a perfect 4.0?

Some schools cap A+ at 4.0 like a regular A, while others award 4.3 — this tool uses the common 4.0-cap convention; check your registrar if your school does otherwise.

Can I use this for a weighted high school GPA that includes AP/Honors bonus points?

Not directly — this uses the standard unweighted 4.0 scale. A weighted scale would need extra points added to each qualifying course's grade point before entering it here.

How to use it

Enter each course's Grade and Credits, or use Add course for a new row.
Read your weighted GPA and total credits in the readout.

Formula

GPA = Σ(grade points × credits) ÷ Σ(credits)

Worked example

One 4-credit A (4.0) and one 3-credit B+ (3.3): (4×4.0 + 3×3.3) ÷ (4+3) = 25.9 ÷ 7 ≈ 3.7 GPA.

Letter grade → GPA points (this tool's scale)

Letter grade → GPA points (this tool's scale)
Letter	Points	Letter	Points
A+	4.0	C+	2.3
A	4.0	C	2.0
A-	3.7	C-	1.7
B+	3.3	D	1.0
B	3.0	F	0.0
B-	2.7

Recommendations

• Add every course for the term to get an accurate weighted average — leaving out a low grade will inflate the result.
• If your school uses plus/minus grading, double check this tool's grade-point mapping matches your registrar's scale.
• Recompute after each term to track your cumulative GPA trend, not just one semester's number.

Frequently asked questions

It uses the common 4.0 scale (A = 4.0 down to F = 0.0). Some schools use plus/minus increments or weighted scales for honors/AP courses that differ slightly — check your registrar's scale for an official figure.
