Common Questions & Guidance
Frequently asked questions regarding Compound Interest Calculator.
What is the Rule of 72?
The Rule of 72 is a quick way to estimate when your money will double at a fixed rate. Divide 72 by your annual interest rate. For example, at an 8% return rate, your money will double in approximately 9 years (72 / 8 = 9).
How does compound frequency affect returns?
The more frequently interest is compounded (e.g. daily vs. annually), the faster your money grows. However, the difference between monthly and daily compounding is relatively small for standard portfolios.
