Frequently Asked Questions

The US Federal Reserve targets 2% annual inflation. Historical average US CPI inflation is around 3–3.5% per year. High-inflation periods (like 2021–2023) saw rates of 7–9%. For long-term planning, 2–3% is a common assumption.

Nominal value is the face amount in dollars. Real value adjusts for inflation — it represents actual purchasing power. If $1,000 today buys a certain basket of goods, real value tells you how many of those same goods you can buy in the future with $1,000.

At 3% inflation, prices double roughly every 24 years (Rule of 72). A $50,000/year retirement income today would need to be $90,000+ in 20 years to maintain the same standard of living. This is why inflation-adjusted returns matter in retirement planning.
