I'm continuing to churn away my finanical calculator to estimate my retirement costs and potential retirement dates. For health insurance, a typical policy with maybe a thousand dollar deductable, I am estimating a 10% increase per year for each year from age 55 to age 65. Does this sound like it might be in the ball park, low or high? I know it's a bit of a guess, but want a reasonable figure to work with. Second opinions would be helpful.
