How to Calculate GPA Using Credit Hours

A step-by-step formula, worked example and common GPA mistakes.

Direct answer

GPA summarizes academic performance by weighting each course’s grade points by its credit hours. Multiply, add the weighted points, then divide by total credits.

A practical method

  1. Define the outcome or value you need to calculate.
  2. Collect only the information that affects that outcome.
  3. Apply the formula or criteria consistently.
  4. Check the result against a worked example or institutional rule.
  5. Record assumptions and revise when circumstances change.
Worked example

Start with simple values you can check manually. If the result from the tool differs, review units, percentages, weights and rounding before using it.
