Understanding Doubling Time
What is Doubling Time?
Doubling time is the period required for a quantity to double in size or value at a constant growth rate. This concept is crucial in finance, biology, and population studies.
The Rule of 72
A quick way to estimate doubling time is using the Rule of 72: simply divide 72 by the growth rate percentage. For example, at 6% growth, money doubles in approximately 72/6 = 12 years.
Common Applications
