Calculation used
What this calculator uses
The inputs on this page are State PDH requirement, Eligible PDHs completed. The result is the positive difference between the requirement you enter and the eligible credits you say are complete; extra credits never create a negative balance.
How to read the result
Use the result as a gap or timing check, then open the cited authority before buying a course, reporting credits, paying a fee, or submitting a renewal.
What the number does not prove
PE continuing-education rules are jurisdiction-specific. Verify exemptions, carryover, ethics/state-law content, approved activities, and the renewal deadline with the state board.
Best next step
Use the result as a gap or timing check, then open the cited authority before buying a course, reporting credits, paying a fee, or submitting a renewal.
