Frequently Asked Questions
What does purchasing power factor mean?↓
A purchasing power factor of 0.70 means a dollar in 10 years will buy only 70% of what a dollar buys today.
What is the Rule of 72 regarding inflation?↓
Dividing 72 by the inflation rate reveals how many years it takes for prices to double (e.g. 72 / 3.5% = ~20.5 years).
How can investors protect wealth against inflation?↓
Historically, equity index funds, real estate, and Treasury Inflation-Protected Securities (TIPS) have outpaced consumer price inflation over long horizons.
Does official CPI inflation match individual household inflation?↓
No, personal inflation varies depending on how much of your budget is spent on healthcare, education, rent, and gasoline versus consumer technology.
