This type of policy is more important if you are married and/or have children. Your life is valuable because it is what allows you to work and earn an income to provide for your family. When you are gone you create an income gap which could put your spouse or children in financial trouble.
Death is hard enough; don’t make it even harder by putting your loved ones in a financial jam if the unfortunate does happen. Funerals alone can be expensive and it creates even more stress on the family. At the very least you should have enough to cover basic funeral expenses and provide a cushion for your family, and at most it should provide a stream of income for your family that can replace what is now gone.
You should buy about 12 times the amount of money you would need annually to replace what the family member is contributing. For example, if you would need $40,000 a year to replace the death of an employed member, you would need a $480,000 (rounded to $500,000) policy.
