Roger,

I don't know of any software program for that, but
every life insurance company (including ours) arms its agents with a needs analysis pro forma sheet. It comes down to what you want to cover in the event of your demise. You should consider: cash needs such as your mortgage, any credit card debt or other loans, final (gulp!) expenses such as funeral, estate costs, etc., an emergency fund for your heirs, and income needs such as an education fund for the kids and family income. From this you can subtract current liquid savings and current life insurance. You'll probably find that you are not over-insured. Remember, you don't want to leave your heirs rich (by life insurance anyway!), just able to adjust financially. Hope this helps!!
