How it works

Semester Grade measures a percentage average across a course load.

FormulaAverage = Σ(course grade × credits) ÷ total credits

The result panel exposes the inputs and intermediate values so the answer can be checked.

Important assumptionPercent-to-GPA conversion is institution-specific.

Instructor, school, and gradebook rules take precedence over this planning estimate.

Use the scenariosCompare the weighted and simple averages.

Change the inputs and calculate again to test a realistic range instead of relying on one number.

How to use this result

Multiply each course percentage by its credit hours, add those products, and divide by the total credits. Higher-credit courses have more influence.

An 80% grade in a 3-credit course and 90% in a 1-credit course produce an 82.5% credit-weighted average.
