What we do in my office, is have our small business health insurance plan sold through one of our local brokers. In my office, we provide coverage options for all fulltime employees after 3 months of employment, with option for their family members(we pay for the employee, the employee pays for the family members). Curremtly we have a mix of 19 on our office plan between employees and family members, and it costs us about $3250 per month for this pla, which has Rx co-pays in the $20 neighborhood and M.D./D.O. office visit co-pays at $30. By comparison, 3 years ago a very similar plan (with lower co-pays) was about $2600 a month for the same number of folks.
These figures are something that when you're talking total compensation(i.e. hourly salary + benefits) for your employees, you bring this up, because it will often add a couple of dollars an hour to their total compensation package.
