Suppose a surviving spouse didn’t work and had two children, ages 4 and 1, in her care. Suppose her deceased husband earned $36,000 at death and was covered by Social Security but had no other death benefits or life insurance. Assume the surviving spouse is 36.
Assume that the deceased spent $6,000 from income on his own living expenses and the cost of working. Assume, for simplicity, that the deceased performed services for the family (such as property maintenance, income tax and other financial management, and occasional child care) for which the survivors will need to pay $6,000 per year. Assume that the survivors will have to buy health insurance to replace the coverage the deceased had at work, and that this will cost $12,000 per year.
Taken together, the survivors will need to replace the equivalent of $48,000 of income, adjusted each year for an assumed 4 percent inflation.
Thanks to Social Security, the survivors would need life insurance to replace only about $1,700 per month of lost wage income (adjusted for inflation) for 14 years until the older child reaches 18; Social Security would provide the rest. The survivors would need life insurance to replace about $2,100 per month (adjusted for inflation) for three more years when the non-working surviving spouse has only one child under 18 in her care.
The life insurance amount needed today to provide the $1,700 and $2,100 monthly amounts is roughly $360,000. Adding $15,000 for funeral and other final expenses brings the minimum life insurance needed for the example to $375,000.
