What is compound interest and how does it differ from simple interest?

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

How does compounding frequency impact total investment return?

More frequent compounding (e.g. daily or monthly vs annually) generates slightly higher overall yields because your interest begins earning additional interest sooner.

What is the Rule of 72 in compound investing?

The Rule of 72 is a quick estimation formula: divide 72 by your expected annual interest rate to find the approximate number of years needed to double your initial money.
