How do credit hours affect GPA?

Credit hours affect GPA because course grades are usually weighted by GPA-bearing credits. A grade in a four-credit course changes the average more than the same grade in a one-credit course.

A higher-credit course carries greater GPA weight

Fictional example: suppose an A is worth 4.0 grade points and a C is worth 2.0. Multiply each value by the course’s GPA-bearing credits.

A14.04
C42.08

The GPA is 12 quality points divided by five GPA-bearing credits: 2.4. Averaging the two grade-point values equally would produce 3.0, which incorrectly gives the one-credit course the same weight as the four-credit course.

Credits earned toward graduation are not always identical to credits included in GPA. Transfer and pass/fail credit may count toward a degree without entering the institutional average. Check your transcript and registrar’s rules before using total earned credits in a GPA projection.

Your next steps

  • Identify which credits count in the GPA calculation.
  • Weight each grade by those credits.
  • Use the correct credit total when projecting future grades.
