I'd guess about 4x increase on insurance. ~$300 for my contribution to an employer plan, vs. about $1200 now, plus whatever dental costs. Also on a mid-tier plan, vs the premium one offered by the employer. That's for two people.

But again, insurance is 100% deductible, and so are most of your out-of-pocket medical/dental expenses, so ends up being not so bad. Still sucks to write the check.
