Equation:
(M x 12) + MOOP = Worst case scenario cost
Where M equals the monthly cost and MOOP is the maximum out of pocket amount. So, if a plan costs $500 a month and the maximum out of pocket amount is $12,000 - which in a worst case scenario you would pay (it's almost always over the deductible) ...
($500 x 12) + 12,000 = $18,000
Most people look at the deductible, but be aware this is incorrect in a worst case. The last one (maximum out of pocket) really hurts most people because they overlook it:
Deductible vs. out-of-pocket maximum
The difference between your deductible and an out-of-pocket maximum is subtle but important. The out-of-pocket maximum is typically higher than your deductible to account for things like co-pays and co-insurance. For example, if you hit your deductible of $2,500 but continue to go for office visits with a $25 co-pay, you’ll still have to pay that co-pay until you’ve spent your out-of-pocket maximum, at which time your insurance would take over and cover everything. New in 2016: embedded out-of-pocket maximums One change in 2016 is that, even with an aggregate deductible, one person cannot pay more than the individual out-of-pocket maximum within a family plan, even if the aggregate deductible is more than the individual out-of-pocket maximum, which is $6,850 for 2016. For instance, even if the overall aggregate deductible was $10,000, a single person in that family plan could not incur more than $6,850 in out-of-pocket expenses. (In 2017, the out-of-pocket maximum will increase to $7,150.) After they hit that number, insurance covers everything for that person, even as the rest of the family is still subject to the deductible.
From your question:
Thanks - not sure I totally follow you. My question is, essentially:"Say a typical large employer X gives you 'healthcare' as a benefit on top of your salary. In fact, how much does that cost corporation X each year?" ie, meaning, in the US, about how much does that typically cost a corporation X each year?
That's a good question because they may qualify for tax advantages by offering to a number of employees and there may be other benefits if they encourage certain tests (like blood work and they waive the monthly fee). More than likely, using the above equation may be the maximum that they'll pay each year per employee and it might be less depending on the tax qualifications. You can read this answer of the question and it appears they are paying within the range of these premiums listed above this.
