Hilariously, it suggested that not only am I on track to retire, but that I should consider increasing my lifestyle spending or retiring earlier than planned. Okay!
It wouldn't let me plan to live longer than 95 years old. Grandpa lived to 93 after smoking and drinking his whole life, so I'm shooting for 100.
In the results section, it gives you a breakdown of what portion of your projected living expenses might be from health care costs, but it doesn't provide much info on how it calculates future rates, or what kind of insurance you have. I recognize that they are trying to encourage people to contribute to HSA plans, which is fine, but it's not a very useful planning tool for more sophisticated users unless they offer some more detail about how they arrive at their numbers.
It looks like it is designed to predict health care costs based on whatever ailments you expect to have. The more problems you tell it you expect to have, the higher health care costs it predicts for you. I think most people already know that they need good insurance if they plan to be super unhealthy.
Also, the total dollar amounts it says you will need don't seem to jive well with other web calculators or my own calculations.
Overall, I'm not impressed.
