What are we checking against? SS earnings? or Medicare earnings? I'm at 75% and 53%.
So glad you asked this--I was thinking the same thing. As ARS pointed out, it's a useless but VERY VERY VERY fun thing to calculate and even track--and I love the idea of having a goal of 100%! :) But I'm still left wondering: what philosophy would be best to use for this kind of calculation?
One way to do it would be gross earnings--of which the government takes some (Federal tax, state tax if any, Medicare, SS), of which we spend some (pre-tax deductions like health insurance), and of which we save some (401k/403b, and so on). But then that's almost not fair--we didn't ever get to touch the government portion, so can we really count that as "earnings" when we never actually got it into our hands?
Another way to do it would be a money-we-touch rate: your net take-home after all deductions. But then some of the money you didn't take home was either spent for your benefit (insurance) or saved for your benefit (401k), so that money was "yours" even though it never hit your account.
I'm kind of on the gross earnings bandwagon, myself--not just because it makes the calculations easier, but because you DID earn all the money; it's just that some of it was "spent" on taxes and insurance, and some of it was "saved," even if those dollars never hit your bank account.
