What is the Rule of 72 and how does it work?

Divide 72 by your expected annual interest rate to approximate how many years it takes for your investment capital to double (e.g., 72 / 8% = 9 years).

How does compounding frequency impact investment yields?

More frequent compounding (daily vs annual) yields higher returns because interest earned starts generating its own interest sooner, maximizing exponential growth.

What is the difference between nominal and real returns?

Nominal return is the raw percentage gain before expenses and inflation. Real return subtracts the inflation rate to reflect actual purchasing power growth.

How do expense ratios affect long-term compound growth?

A seemingly small 1% mutual fund fee can consume over 25% to 30% of your total lifetime compound portfolio gains over a 30-year investing horizon.

Frequently Asked Questions

How does compound interest accelerate wealth building?
