Do you have $15,000 cash handy? If yes, you probably don't need to worry about insurance. I think it's irresponsible to not carry at least enough insurance to pay for a funeral.
It's been three years, but two of my aunts passed away at about the same time. Both had a plot waiting for them, so there wasn't that expense.
One had $5000 life insurance. That wasn't enough to pay for the minimum...and I mean MINIMUM costs of dieing. Cremation, urn, small vault, opening and closing the grave, and the headstone (basic, flat to the ground) were over $6000.
I was able to use money from the second aunt's insurance to cover that extra $1000+.
If I'd had to purchase plots for them their combined insurances wouldn't haven't been enough to cover the costs.
Mind you, we're talking cremation, no funeral home services, BASIC urns and headstones.
To consider a casket and the costs involved with that, transporting bodies from where they died to where their plots are, etc, it would have cost over $20,000 each.
Prepaid plans sound nice, but there is a lot of controversy about them as they often don't come through with what they promised.
It's nice if you can carry enough insurance to pay off your mortgage and bills...that's a nice little perk for your family...but it's necessary to cover enough to pay for the expenses they'll incur after your death.
