When Would you need to use Rule 72 ?
You would need to use Rule 72 when you want to estimate how long it will
take for your money to double by compound interest. Rule 72 is a simple
mathematical formula that approximates the number of years it takes for an
investment to double in value based on a fixed annual interest rate.
The formula is easy to remember:
Years to Double = 72 / Annual Interest Rate
For example, if you invest $10,000 at an annual interest rate of 6%, using the
Rule of 72, you can estimate that it would take approximately:
72 / 6 = 12 years
for your original investment to double to $20,000.
Rule 72 helps people to quickly understand how much time they have before
their investment reached a certain point, and it can be useful in financial
planning, investment decision making, and other personal finance activities.
