The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life. As an example, Canada's net population growth was 2.7 percent in the year 2022, dividing 72 by 2.7 gives an approximate doubling time of about 27 years.
In finance, the rule of 72, the rule of 70 [1] and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling.
A popular approximated method for calculating the doubling time from the growth rate is the rule of 70, that is, /. Graphs comparing doubling times and half lives of exponential growths (bold lines) and decay (faint lines), and their 70/ t and 72/ t approximations.
In 1830, the GDP was 41,373 million pounds. It grew to 1,330,088 million pounds by 2008. A growth rate that averaged 1.97% over 178 years resulted in a 32-fold increase in GDP by 2008. The large impact of a relatively small growth rate over a long period of time is due to the power of exponential growth.
TIL The U.S. Navy estimates that heavy barnacle growth on ships increases weight and drag by as much as 60 percent, resulting in as much as a 40 percent increase in fuel consumption. #45
COLA over the last decade: 2025 to 2024 COLA has varied widely over the past 10 years. The lowest COLA in that timeframe was in 2016 at 0.0%, and the highest was in 2023, when COLA was a whopping ...
I set a goal to transform 50 percent of my body weight into muscle within a year. So, I took Orangetheory circuit training classes three times a week, working on both strength training and cardio.
Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. [ 1 ] Moore posited a log–linear relationship between device complexity (higher circuit density at reduced cost) and time.
