Frequently Asked Questions

What inflation rate should I use for planning?

The U.S. Federal Reserve targets 2% annual inflation. Historical averages are closer to 3%. For conservative planning, use 3–4%. For healthcare and education costs, which inflate faster, use 5–7%.

How does inflation affect retirement planning?

Inflation is one of the biggest threats to retirement security. If you retire at 65 with $50,000/year in expenses, at 3% inflation you'll need roughly $110,000/year by age 90 for the same lifestyle.

What's the difference between nominal and real returns?

Nominal return is your investment return before inflation. Real return subtracts inflation. If your portfolio returns 7% and inflation is 3%, your real return is approximately 4%.
