If $23 goes to the government for tax, that means that the item price (pre-tax) was $77.To get an apples-to-apples comparison of the tax rate under the Fair Tax, we'd need to use the same formula as above:[$100 - $77] / $77 = 29.8%In other words, the Fair Tax guys decided to use a mathematical trick (tax-inclusiveness vs tax-exclusiveness) to make the tax percentage sound smaller.The FairTax.org website freely admits this, though they do their best to bury the information.

Many calculations surrounding returns are based on fancy financial mathematics and university style formulas, but those of us who are in the trenches know that it is critical to separate two entirely different realities.First there is deployed v. not deployed capital.

You can show your wife mathematically how quickly you can pay off your home.Let's say you can show your wife that your primary can be paid off in 5 years so you are totally debt free in five years.

It is a mathematical fact that if you are buying a rental property in any city where the monthly mortgage payment exceeds monthly rental income, or where mortgage payments along with monthly expenses exceed monthly rent, if any of those scenario applies, a down payment would be only other material method to avoid a negative cash flow situation.You let the investor worry about his gamble on the market going up.. thats not your problem.

Mathematics or business classes would be good

The one great standout way, the royal road, simply does not exist.The question, as I'm reading it, is how to go from taking home $120,000 a year FREE AND CLEAR (FCF= Free Cash Flow), to taking home $1.2M FCF.Imagining that it's going to come from ONE WAY is a mathematical wet dream.

Mathematically, that's the highest return possible because what could be a higher return than something for nothing?

Now as to whether you should sell or not this year, it is a purely mathematical one.

So far, these are the questions I have for myself at the moment:What factors must you include in your mathematical system?

I only pointed out the mathematical fact that the .5% rent ratio means the market has determined that the rent in that market is more desirable.
