We're 55 and 54 and will definitely retire within 5 years if not sooner, so will need to purchase insurance on the ACA marketplace. In just glancing some of the policies awhile back, a platinum plan (the equivalent to what my husband has for us at work), would set us back around $2,600 a month. That comes with a $2,500 deductible as well.
The Wall Street Journal has been running a series of articles, "What it Looks Like to Retire with....500K, 1 million, 2 million, and recently ran the 5 million dollar scenario. There are usually four people or individuals and you get a glimpse into what their lives are like. That is just their nest egg (or close to it) in most cases, not their net worth and almost all were either receiving SS or would in the future. Some had pensions as well.
In the 5 million dollar group, one couple employed an interesting strategy. They are 61 and 60, had a nest egg of 4.3 million, lived in Cary NC with a house worth 975K. Half of their investments were in tax advantaged funds, half taxable. They spent 130K per year. The article didn't say that they were doing this on purpose, but my guess is that they were.....but they were mostly living on cash reserves and therefore were receiving subsidized healthcare and paying $1,000 a month. I would guess that they're saving easily 18K a year, possibly more, by deploying that strategy.
I guess one could debate the ethics of this, but on the other hand, it's smart. There is no means testing for ACA with respect to net worth....only income. The government mandates that you purchase health insurance. You can be fined if you don't. And if you're living on a pile of cash in the early years of retirement and not touching taxable investments like a traditional 401K or a taxable account (capital gains)....it makes sense to spend cash and keep your modified adjusted gross income very low. The "return" on your money is fabulous. In some ways, it's like the "backdoor Roth IRA"....that my DH and I have been taking advantage of for years. It's a loophole that should be closed...but hasn't been.
