What is considered as an expense? Does paying insurance consider as an expenses or an investment?

If you think about what Robert Kiyosaki says; Assets put cash into your pocket, Liabilities take cash out of your pocket.

I would have to say insurance that does not have cash value would be consider as expenses and those that hold value such as endowment would be considered as savings/investments.

Most insurance is expense. But if the insurance has a savings or investment portion, that is considered savings or investment.

As long as money goes out and does not generate value, its expense.
