What is compound interest?

Compound interest is interest calculated on both the initial principal and accumulated interest from previous periods.

How does compounding frequency affect returns?

More frequent compounding (daily vs yearly) increases returns slightly. The difference grows with higher rates and longer terms.

Divide 72 by your interest rate to estimate years to double your money. At 8%, money doubles in ~9 years.

Aim for 15-20% of income for retirement. Start early - time is the biggest factor in compound growth.
