There are premium subsidies available in the exchange, but you're not eligible for them if the plan offered by your employer is considered affordable and provides minimum value (this is true for your family members as well, if they have access to your employer-sponsored plan, even if the employer-sponsored plan is only affordable for the employee's portion of the coverage; this is known as the family glitch). Most employer-sponsored plans are affordable and do provide minimum value. So if you're shopping for an individual market plan instead, chances are high that you'll have to pay full price for it, without any subsidies.
Individual and family health insurance plans can help cover expenses in the case of serious medical emergencies, and help you and your family stay on top of preventative health-care services. Having health insurance coverage can save you money on doctor's visits, prescriptions drugs, preventative care and other health-care services. Typical health insurance plans for individuals include costs such as a monthly premium, annual deductible, copayments, and coinsurance.
