Subtract completed eligible credits from a stated renewal requirement and avoid counting more than the requirement. The useful output is not just the number: it is the number together with the assumptions and eligibility checks that can change what you should do next.
Calculation used
What this calculator uses
The inputs on this page are Credits required, Eligible credits 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
Credit labels are not universally interchangeable. Check the receiving credential’s definition, eligible activities, rounding rules, and reporting process before counting the result.
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.
