Cumulative GPA accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • The calculator converts your current GPA back into total 'Quality Points' (Current GPA × Current Credits). It adds the new points from the current semester, then divides the new total points by the new total credits.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Current Cumulative GPA: 3.2
  • Credits Earned So Far: 60
  • New Semester GPA: 3.8
  • New Semester Credits: 15

Expected outputs

  • New Cumulative GPA: 3.32
  • Change: +0.120
  • Total Credits: 75

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • This calculator assumes both GPA values use the same unweighted 4.0 grading scale.
  • All entered credits are treated as GPA-bearing credits rather than pass/fail, audit, or transfer-only hours.
  • School-specific grade replacement, repeated-course policies, and institutional rounding may change the official transcript result.

Unit handling

  • Current Cumulative GPA accepts numeric values.
  • Credits Earned So Far accepts numeric values.
  • New Semester GPA accepts numeric values.
  • New Semester Credits accepts numeric values.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
