If you get a high rate quote in a letter from your insurer, it might be worth your while to take a look at the state insurance exchange. The 'old reliable' companies are getting competition, something that they aren't used to.
I've already got our new rates for Bronze plans. For DD, we got a 'huge' rate increase for her individual insurance, one of those really scary percentages that the editorial writers like to carry on about. It's about $60 a month. The rates for DW and I went down a bit, slightly more than DD's went up. Considering that unsubsidized individual insurance for the three of us is well over $1000 a month for our HD/HSA plans, and the rates for DW and I dropped slightly, it's a wash for our budget.
Folks seeing large rate increases should check the exchanges for better rates for the same level of coverage. It might also be educational to compare the level of coverage, exclusions, and limits of old policies against the exchange plans. DD had one of those college student Mega-Life plans that had fairly silly carve-outs and caps ($2,500 max for hospitalization? That's 30 minutes in the ER if they don't do anything!) I'm not surprised that a real insurance policy costs more.
