The Rule of 72 works best in the range of 5 to 10 percent, but it’s still an approximation. To calculate based on a lower interest rate, like 2 percent, drop the 72 to 71.
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.
“The Rule of 72 is a quick way to estimate how long it will take for an investment to double, based on a fixed annual interest rate,” says Kovar. ... if your investment earns 6% annually, it ...

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. Thus if that growth rate were to remain constant, Canada's population would double from its 2023 figure of about 39 million to about 78 million by 2050.
The rule of 72, a mathematical result, states that if something grows at the rate of x% per year, then its level will double every 72/x years. For example, a growth rate of 2.5% per annum leads to a doubling of the GDP within 28.8 years, whilst a growth rate of 8% per year leads to a doubling of GDP within nine years.
Using the Rule of 72, your money should double every 10.3 years. So, by age 45, you should have around $200,000 in retirement savings. By age 55, you should have around $400,000.
The formula contained in this law, which determined the amount due to lenders, was called the "rule of 78" method. The reasoning behind this rule was as follows: A loan of $3000 can be broken into three $1000 payments, and a total interest of $60 into six. During the first month of the loan, the borrower has use of all three $1000 (3/3) amounts.
