II · THE MATH
Why the middle feels so slow
This is the part most money content skips, because it is not encouraging. It is, however, the single most useful thing to understand, and once you have seen it the rest of the plan makes sense on its own.
Here is someone investing $800 a month at 7% a year, starting from nothing. Look at the right-hand column, not the left.
| Getting to | Total time elapsed | Time for that step alone |
|---|
| $10,000 | 1.1 years | 1.1 years |
| $25,000 | 2.4 years | 1.3 years |
| $100,000 | 7.9 years | 5.5 years |
| $250,000 | 14.9 years | 7.0 years |
| $500,000 | 22.1 years | 7.2 years |
| $1,000,000 | 30.3 years | 8.2 years |
The first $100,000 costs you 7.9 years. Going from half a million to a million costs 8.2. Nearly the same slice of your life, for ten times the money. Nothing changes about the strategy in between. Only the size of the base.
So the grind is not a sign you are doing it wrong. It is the shape of the thing, for everybody, including everyone who has already finished it. The only variable you control is whether you are still contributing when the curve finally turns.
And the one number that decides all of it
Years until your investments could cover your spending, based only on the share of your take-home pay you save. Starting from zero, 7% a year, using the 4% rule as the finish line.
| You save | Years until work is optional |
|---|
| 5% | About 51 |
| 10% | About 40 |
| 15% | About 34 |
| 20% | About 30 |
| 30% | About 23 |
| 40% | About 18 |
| 50% | About 15 |
Your income does not appear in that table anywhere. That is the point. Saving a bigger share grows the pile faster and shrinks the pile you need, both at once, which is why moving from 10% to 20% buys you a decade and moving from 40% to 50% buys you three years.
Every figure above is arithmetic, not a forecast, and the assumed rate is printed on the page. Markets do not deliver a steady 7%; they fall for years at a time and the order matters. The book says so on every table, which is more than most of them do.
What people say under the videos
Straight answer first: these are comments left on the free videos on YouTube. They are not reviews of the book, because the book is new and nobody has read it yet. They are here because they are the same people the book was written for, saying the same things it is about.
That one is correct, and it is why Chapter 10 has a separate plan for $50,000 than it does for $300,000. At the lower end the honest answer is that cutting has a floor and the real lever is income, and the book says so instead of pretending a budget template fixes it.
