I'm pretty sure the original 10+k/yr/employee for good ppo coverage is a radical underestimate, for what it's worth, though I guess "way more than ten" is technically part of the "ten+" range, haha.
The last time I had reason to look at full market-rate price for a family of four for a good PPO (Seattle market, circa five years ago, large tech company), it was around 3300 USD per month, or over $39k/yr. That was for cobra coverage, so a combination of what I would have normally paid and what the employer would've (about one third us and two thirds them when I was employed by that corp). I can only imagine it's gotten more expensive since then; we left the country three years ago.
Just as an FYI, that is a massive outlier based on available data.
My employees are about $500 per month in a major metropolitan area, and a family of 4 can run up to $2000 a month for the most expensive plans (I cover individuals and their spouses in full for standard plans, and could cover one dependent for basic plans).
I looked at marketplace plans in WA because I was curious, and it looks like it's about the same as where I am but nowhere near what you were quoted 5 years ago.
I got the $10k a year employee from chatgpt with "Assume I have a company with 100 employees in New York, how much on average does it cost to provide health insurance" and it gave me poor, moderate and good ppo plan prices. I figure this seemed reasonable for ballpark figures from employer friends, so the numbers may be very well off.
