At least until the end of 2024, insurance premiums are capped via subsidies (either paid directly, or as tax credits). The computation of the cap is extremely complex, but basically: you do not pay more than 8.3% of your household AGI for your state's 2nd most expensive silver-level insurance plan.
This is not widely talked about. It was a part of the ACA, but there was a salary cap somewhere near 100k/yr. The cap was removed during the COVID19 pandemic, and this currently runs to the end of 2024.
I used to pay $1300/month for my wife and I (in our late 50s); I currently pay $440/month (annual income approx $120k).
I see the full $30k+ in annual premiums that my employer plus I am paying in my W-2 (box 12 code DD), which is money that could have been cash compensation.
This is not true anywhere in the US. The lowest premiums are ~$400 per person per month for bronze level insurance.
Lowest premiums for a family of four would be ~$2k per month plus annual deductible of $5k to $10k plus annual out of pocket maximum of ~$10k to $17k (legal limit).
