Very cool. I wish I had this when shopping for insurance a year ago.<p>A "total annual cost" column would be helpful for making sense of the deductible/premium/co-pay relationship. Think of it as the "Price+Shipping+Tax" on shopping websites.<p>Ask the user how much he expects his doctors to charge him ("Annual Medical Bill") in the next twelve months, then calculate how much he would pay to the doctors and to the insurance company. Last time I bought health insurance I had to make a spreadsheet to calculate this. I would rather not repeat that mundane task again.<p>It might also be useful to have multiple predefined Annual Med Bills ($0, $1,000, $5,000, $20,000, etc). Displaying the output on a graph might make sense (AnnMedBill vs TotalAnnCost, with a curve for each plan). You should customize these to the user's age (a 23 year old may not go to the doctor for years at a time, but even a healthy 50yo will definitely go several times per year for checkups and *oscopies).<p>Mapping costs to life events (no doctor visits, a few visits, broken arm, healthy pregnancy, etc) would make it even more useful, but researching the necessary assumptions will take considerable work so just implement predefined dollar amounts as a version 1.<p>Keep up the good work, this idea has value!
