What is typically included in periodic expenses?

Periodic expenses refer to expenses that occur at regular intervals but not on a monthly basis. These can include costs that are incurred annually, semi-annually, or quarterly. The answer given, which is annual insurance premiums, perfectly exemplifies a periodic expense because it typically occurs once a year.

Monthly subscription fees, while regular, happen on a monthly basis and thus are classified as recurring monthly expenses rather than periodic expenses. Daily grocery bills are classified as everyday or variable expenses since they can change from day to day. Similarly, weekly entertainment costs are more frequent regular expenses and do not fit into the typical understanding of periodic expenses.

Therefore, the nature of annual insurance premiums as a cost incurred once a year aligns well with the definition of periodic expenses, making it the correct choice in this context.
