faq
What is the Rule of 72?
A simple way to estimate assets doubling time; divide 72 by the annual interest rate.
Simple vs Compound interest?
Simple interest is only on principal; compound interest earns "interest on interest," growing exponentially.
Does it include taxes?
Calculations are pre-tax, intended to show the general trend and growth of investments.
