T.K.
I sell life insurance so let me explain the best way I know how.
There are 2 basic types of life insurance.
Term - This is like "renting" insurance. You buy a policy for a certain period of time, say 20 yrs and the premium stays the same. Does not build cash value or earn interest. If you don't die within that 20 yrs than you get nothing and you have to buy more insurance at a higher rate.
Whole Life - This is more like "buying" insurance. You buy a policy and it is meant to last you your whole life. This type earns interest and you can borrow against it or take money out of it once you've paid enough in.
Term is much cheaper in the beginning. Good for parents of small children or new home buuyers. You can get a lot of insurance fairly cheaply. Once the term is up you may have to requalify and it is significatnly more expensive.
Whole life is more expensive initially but over the long tem it doesn't go up when you get older and it has the benefits of getting some of your money out later. It's very cheap for infants, so good to get the kids a whole life policy early.
