Just to account for inflation you'd probably have to deflate your income by 50%. And if you have dependents you'd have to split your household income with them too.On top of that, plug in $1,000,000 and then run $250,000. You will get the same ranking. There's a definite lack of precision in their calculations.But I can see how a lot of people would see this and hear the message they're trying to give, which is probably all they care about.
