How to use this result
A $2,000 biweekly check averages $4,333.33 a month over 26 checks. The same $2,000 paid twice a month averages $4,000 because there are only 24 checks.
An average is useful for annual planning, but it is not a deposit calendar. Budgeting recurring bills against the usual two-check month can be more conservative than spending the annual monthly average.

Common questions
