GPA Calculator

Calculate your GPA from grades and credits.

How to Do It Manually

GPA (Grade Point Average) is calculated by converting letter grades to numeric points (usually A=4.0), weighting by credit hours, then averaging.

GPA = Σ(grade points × credit hours) ÷ Σ(credit hours)
  1. Convert each letter grade to points: A=4.0, B=3.0, C=2.0, D=1.0, F=0.
  2. Multiply each grade point by the course's credit hours.
  3. Sum all (points × hours).
  4. Divide by total credit hours.

Frequently Asked Questions

What's the difference between weighted and unweighted GPA?

Weighted GPA counts honors/AP classes more heavily. Unweighted treats all classes equally.

Does +/− affect GPA?

Some schools use A+=4.3, A=4.0, A−=3.7. Others ignore +/−. Check your institution.
