As you have discovered, life insurance is something you should have purchased and locked in a premium decades ago. My wife and I bought $500,000 coverage each when we were 29 when our first child was born. When our kids were through with College, we cut the insurance to $250,000 each. The premium is $123 a month for me, as I am male and a higher risk, and $50 for my wife. Even though we were only 29 when we bought it, we had to have an Insurance company Doctor do a physical and had to have blood work done to qualify. At this point we are keeping the coverage for one reason. When one of us passes, the idea is the life insurance payout will help ease the loss of the deceased spouses Social Security. We both started Social Security this year, and our Social Security is almost to the dollar equal to what we were bringing home working. We are not touching our retirement savings......IRAs that are 401k Rollovers. Of course, in 6 years we will HAVE to start minimum distributions when we turn 73, but it doesn't mean we have to spend what we take out, and I don't anticipate needing any of that money.
My mom dropped all her life insurance when I was out on my own. She instead purchased long term care insurance with that premium money. Long term care insurance is also something you should have and should have gotten years ago. My premium for that is about $2,500 a year each, so about $200 a month each. As a 67 year old, I did look at switching companies, but because of my age, buying a plan for us now would run about $7,000 a year each, over $500 a month each.
