Check it outHow GPA is weighted
GPA isn't a simple average of your grades — it's weighted by credit hours, so a 4-credit course counts twice as much as a 2-credit one. Each letter maps to grade points (A = 4.0, B = 3.0, and so on); multiply by credits, sum, and divide by total credits. This uses the standard unweighted 4.0 scale.
How it’s calculated
GPA = Σ(grade points × credits) ÷ Σ credits on a 4.0 scale.

Worked example
An A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class is a 3.43 GPA.
Common mistakes
- Averaging grades without weighting by credit hours.
- Mixing weighted (5.0) and unweighted scales.
Where it is used
- Computing a semester or cumulative GPA.
- Seeing the grade needed to reach a target GPA.
Frequently asked questions
How are letter grades converted?
A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0 on the standard 4.0 scale.
What about weighted (5.0) GPAs?
Honors and AP courses sometimes add points. This tool uses the standard unweighted scale; add the bonus to those grades if your school weights them.
Why do credits matter?
Higher-credit courses influence your GPA more, which is why one bad grade in a big class hurts more than in a small one.
