Welcome to our forum.
It is not uncommon for a single 25 year old to get personal medical insurance for about $1200 a month premiums.
. . . a major medical policy that has a high deductible and requires the insured to pay 20% of the bill AFTER the deductible and copay, and offers little or no benefits for anything other than a major event like surgery . . .
So what are you getting for $100 a month or $400 a month for your family? I would imagine major medical only with personal deductibles at around $2000 or $3000 and family deductibles at $6000 or $8000.. I also imagine this is strictly medical with no dental or eyesight..
