Start with the official total requirement, subtract only eligible completed credits, and separately check mandatory categories such as ethics or law.
Start with the authority-confirmed requirement
Copy the current total, reporting period and mandatory categories from the credential or licensing authority. A remaining-credit calculation is only as good as the requirement entered.
Subtract eligible completed credit only
Exclude activities that are outside the cycle, ineligible by subject/provider, above a category cap, or still incomplete. Keep disputed activities separate until eligibility is confirmed.
A zero balance is not the final status
After the arithmetic reaches zero, check mandatory categories, reporting, fees, audit evidence and the final renewal confirmation.
