Most of this article is fairly reasonable. Its a good approach to answering the question but oversimplifies the issue. I have two main problems with it. The first is this statement:
If you have a solid financial plan in place, you should probably buy $1,100,000 term insurance that would last until you retire. In other words, if you are 45 today and plan on retiring at 65, a 20 year term policy might be the ticket – again, assuming your financial plan was strong.
Your need for life insurance decreases the longer you live and the more you save because your accumulated assets can provide for your beneficiaries and your beneficiaries need the assistance of insurance proceeds for a shorter period of time. This hypothetical person WAY over bought life insurance because he has a full life insurance payout even if he dies a year before he retires-- when all the family should need is a small amount of money to get them through one more year before the "regular" retirement income strategy kicks in.
The other problem I have is that it fails to mention social security survivor's benefits. This is a relatively little-known part of the social security program that has a big impact on your life insurance need calculations because it provides benefits for surviving children and your surviving spouse until the child reaches 16 years old. See this link for more information on this:
https://www.ssa.gov/pubs/EN-05-10084.pdf Of course, you should factor in at least some risk that this portion of social security will be modified/eliminated in the future.
My family took a laddered approach to life insurance. At age 27, I bought a term policy with the following payoffs (I am the primary breadwinner, with an employable wife and one daughter):
(1) 30-year, $250,000 term policy on my life.
(2) 20-year, $500,000 term policy on my life.
(3) 20-year, $300,000 term policy on DW's life.
It also has a rider for a small final expenses payout upon death of children.
I think this is a reasonable way to cover all our needs. If I die soon, but DW and DD survive, they get $750,000. This plus Social Security survivor benefits will leave them well cared for. If wife dies but DD and I survive, I get $300,000 plus social security benefits, which would essentially take pressure off of me and allow me to be more flexible for my daughter but I'd likely continue working. If both of us die, DD gets 1.05 million, plus social security benefits. If I die between 20 and 30 years after we purchase the policy, DD will be out of the house and DW gets a small amount to make any necessary lifestyle changes.
Part of me thinks I overbought but I'd rather miss high than low.
