Days in AR Calculator 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

  • Days in AR = Total accounts receivable / Average daily charges. Estimated monthly charges = Average daily charges x 30.
