He shares a handful of statistics that reveal the stark reality that traditional retirement planning is failing in America.

The goal is to help you understand the flaws of a traditional approach to retirement planning and which components are still useful to consider.
What It Costs To Live A Great Life In Retirement
This chapter kicks off the book by explaining that an inaccurate retirement savings goal is better than having no goal at all. At the very least, you’ll have something to diligently work towards even if you have to make adjustments along the way.
It’s All About The Assumptions, Not The Calculator
In this section of How Much Money Do I Need to Retire?, the cracks in the traditional retirement planning model will begin to be exposed. Although traditional calculators make things seem simple on the surface, the underlying assumptions can be almost impossible to pinpoint.
Tresidder shares some of the unknowable details that many retirement planning models require, such as when will you die. Your retirement planning is only as good as the assumptions you put into the calculator. So it's easy to see how you could run into some serious issues.
The Five Essential Questions
You’ll walk through the five important questions that you need to answer for an accurate retirement nest egg. As you walk through the questions, you’ll realize how difficult it can be to answer these accurately.

How To Accurately Estimate Investment Returns
At this point, you’ll learn about the variables that will affect your investment returns. The three crucial parts include:
- Volatility
- The sequence of returns

How To Estimate Your “Magical” Retirement Number
Tresidder recaps the important lessons that you’ve learned throughout the first section of How Much Money Do I Need to Retire? He also shares more information on the dividend discount model.
Since the goal of the book is to find your retirement number, Tresidder shares calculation options. The first is to plan on recalculating your retirement number every few years by replacing your original assumptions with actual data. With each recalculation, you’ll reduce the potential for error.
The second solution is to build a confidence interval through the variation of key assumptions in this model. With that, you’ll have a comfortable range of what is possible. He will take you through the steps of building out a confidence interval for your retirement plans.
In this section, he touches on the 4% rule. With a brief explanation of the 4% rule, Tressider shares some possible solutions but cautions against solely relying on the 4% rule.

Finally, he gives some advice for using retirement calculators the right way.
Model 2: Lifestyle Planning, The Creative Way
The second model of retirement planning is centered around lifestyle flexibility. Tresidder introduces a list of alternative retirement lifestyles for you to consider. Each could dramatically alter the amount of money you’ll need to save for retirement. Essentially the lifestyle changes include:
- Dramatically cutting your expenses
- Increasing your post-retirement income
- Choosing an alternative investment strategy
Any combination of these choices could have large ramifications on your future retirement. Tresidder encourages you to brainstorm some creative retirement lifestyles and determine how they could affect your savings goal.
Model 3: Cash Flow Planning, The Simple Way
In this final model, Tressider shares his secrets to a secure retirement at age 35. The basic choice was to create income streams that would grow over time to offset inflation. The income streams must not be connected so that if one stream is taken away temporarily, you’ll have other income to support your lifestyle. He outlines three simple rules to follow in order to make this model a secure approach.
