The floor keeps a down year from crediting a loss, but policy charges still come out. If credits don't cover the charges, cash value can go down.
No. It's life insurance. The cash value is credited based on an index, but you don't own stocks or funds.
Whole life has a fixed price and guaranteed growth. IUL has flexible payments and growth tied to an index, with more potential and fewer guarantees.
Payments are flexible, so you often can. Paying less for long stretches can put the policy at risk, so call me first.
