The United States is a very big place, so you'll see a lot of variance in the outcome of this math. For example, my rent is only about 1.2% of my post-tax income. Pre-tax, it's only 0.8%. My savings rate is over 30%.
This is only possible because I live in Florida (in a non-metropolitain area), but am a shareholder in my own company with revenues that support incomes that is much higher than is typical for my market.
