Keep or re-invest elsewhere - A Life Insurance Annuity

[Bill Bonds]

Be gentil, Im young 24, and am still learning....

I have a FarmBureau Life Insurance Policy setup for me in 1990 that earns 4.5% for any funds deposited. I will pay $67 per month for the policy once I take it over from my parents. The way I understand it is if I deposit say... 50K into the account I begin earning 4.5% guaranteed and its locked in as long as I pay the $67 per month.

How do I figure out if this is a good investment vs stocks or bond funds?

Thanks from the newbie.
