It’s not possible to answer this question without knowing details about the plan, the split between employer & employee contributions, and the demographics of the group. Corporate group plans are priced according to the coverage and the health risk of the employees. If you work in a company with a lot of older employees and you have a low deductible PPO plan, the policy could easily be $2,000 per month. Split 80/20, that’s a $400/month employee contribution.
