The Go-Getter saves for the first ten years and then stops. The Slowpoke waits ten years, then saves for the next thirty-three. The Slowpoke puts in more than three times as much money — $181,500 against $55,000 — and still ends up behind.

Here both savers keep going for the full forty-three years. The Slowpoke never catches up, and the gap keeps widening.

Diagram 1

Two-thirds of the Time, one-third of the Dollars

Chapter 5, page 82

Diagram: the first two-thirds of the time accumulate one-third of the dollars

The first two-thirds of the time period, you only accumulate one-third of the dollars of wealth you need. The last one-third of the time, you accumulate two-thirds of the wealth you need.

Diagram 2

The Geometric Jump

Chapter 5, page 83

Diagram: the geometric jump of compounding in the last third of the time

If you have saved faithfully, the "magic" of compounding occurs in the last one-third of the time, generating two-thirds of the returns.

To save $3,000 outside a tax shelter, you have to earn $5,000 and pay $2,000 in income taxes. Shelter it instead — in a 401(k), say — and you can run the same cascade in reverse.

Table 4

Leveraging the equity in your home to create investable cash

Take out a $250,000 mortgage at 4 percent, invest it for returns of 7 percent.

Chapter 6, page 98

CASH IN
Income earned from investing$17,500
Less income taxes on that income (blended capital gains and ordinary rates)−$5,250
Net income$12,250
CASH OUT
4% interest on a $250,000 mortgage$10,000
Less possible tax savings on deducting interest ($10,000 × 40%)−$4,000
Net cost$6,000

If saved in a 401(k), and the tax savings saved too$10,417

Sophie increased her net cash flow by $6,250 a year without working one day longer — and by more than that after tax, because she could deduct the mortgage interest.
