The World's Greatest Get-Rich Formula

You should be highly skeptical of any and all get-rich schemes ... except for the super-simple formula I'm going to show you below. Because this one really works.

It works so well that it's been used by the world's billionaires -- from moguls of yesteryear such as Rockefeller and Ford to today's tycoons Carlos Slim and Warren Buffett.

But enough already. Let's get to the formula.

The formula
It is, simply:

FV = PV * (1+r) ^ n


FV = future value
PV = present value
r = rate of return
n = time (or number of years)

Compounding 101
Now, some astute finance brains will know that equation not as some mystical secret but as the "future value of money" (FVM) equation taught in college.

The FVM formula simply states that your future wealth (FV) is a function of three variables: the amount of money invested today (PV), the rate of return generated (r), and the length of time in which that money is put to work (n). So maximizing future riches requires three steps.

Step 1: Increase PV
It takes money to make money. But by actively and consistently slivering off a portion of your earnings every month to save and invest, you'll have more and more of that money working for you.

All things equal, the greater amount you invest today (PV), the greater wealth you'll build for tomorrow (FV).

Step 2: Increase r
Next, you'll need a way to grow that capital. Historically, the stock market has been the most effective wealth-building vehicle of all. Plowing your money into a low-cost index fund wouldn't be a bad idea.

But if you really want to maximize r, you'll need to allocate a portion of your portfolio to the best segment of the market over the past 50 years: small-cap value stocks. The reason is simple. Unlike behemoths such as $115 billion Merck (NYSE: MRK  ) and $190 billion Johnson & Johnson (NYSE: JNJ  ) -- whose spectacular growth days are behind them -- reasonably priced small caps have tons of room to rocket. Take a look at Fama and French data, which tracked stocks from 1956 to 2005:



Large caps



Small caps



Total stock market


Not adjusted for inflation.

All things equal, the greater your rate of return (r), the greater wealth you'll build for tomorrow (FV).

Step 3: Increase n
The last ingredient in our super-simple wealth building recipe: maximum time in the market.

Look back at the equation. You'll see that n is an exponential function -- meaning that for every year you're not invested, you give up the awesome (almost magical) benefits of compounding.

All things equal, the longer you're invested (n), the greater wealth you'll build for tomorrow (FV).

Plug and chug
To get a feel for the three-step process in action, let's go back in time to see what kind of wealth would have been generated had someone:

  1. Invested $40,000 in the stock market
  2. Started 10 years ago
  3. Divided the money among five stocks having: market caps less than $2 billion (to screen for small size), sales growth greater than 15% (to screen for above-average opportunities), and price-to-sales ratios of less than 1.5 (to screen for a good price).

Here's what it would look like:


Amount Invested
10 Years Ago

Return Over Past
10 Years

Total Value
of Investment Today

Best Buy (NYSE: BBY  )




FTI Consulting (NYSE: FCN  )




Expeditors International of Washington (Nasdaq: EXPD  )




Florida Rock Industries (NYSE: FRK  )




Fossil (Nasdaq: FOSL  )





Total amount invested (PV)

Avg. annual return
of portfolio (r)

Total value of portfolio today (FV)





By having bought into five high-quality, reasonably priced companies while they were still babies, that $40,000 stake would be worth nearly $500,000 today.

Of course, you can always fiddle with the numbers to generate different levels of FV, but our objective should remain the same:

  1. Maximize PV by sticking to an investment plan.
  2. Maximize r by devoting a chunk of your portfolio to superior small caps at attractive prices.
  3. Maximize n by investing as soon as possible and for as long as possible.

    This was a very good article. I liked how it explained the future value equation in detail. I always enjoy reading articles from Motley Fool even if I already know the content.

    Clever article and analysis. The FV equation can also help screen stocks. For example, if you wnat a 50% gain in 3 years, it tells you that you should only invest in stocks that you expect to grow 15% or more each year.

    Although this is a good pitch about the FV of money, it is misleading. It does not take into account INFLATION!! It does not tell you that $40k 10 years ago was a fortune for most of us and if it was not a fortune for you back then, $500k is probably not a fortune for you now. To factor in the decrease in dollar value in your life, don't use the national US figures for that , that is just too abstract and meaningless for most of us. Use the inflation in your particular locale were you live to check the value of $40k. Best measure for local inflation is land. How many vacant acres of land in your neighborhood would $40k have bought you 10 years ago? Let's say 10 vacant acres for the sake of argument. How much would the same 10 vacant acres go for now? Again, for argument sake let us say $100k.

    Use the formula in the article FV = PV * (1 r) ^ n to calculate the inflation rate r where

    FV = 100k, PV = 40k, n=10 year. 100000 = 40000 * (1 r) ^ 10

    gives you r = -10%

    Your actual rate of money "value reduction" in the last 10 years averaged 10% per year.

    In other words, the 27.6% in this article should be 17.6%.

    Still good but not as great as the article would have you believe.
