Most economists generally peg good economic growth in the 2 percent to 4 percent range of GDP, with the historical average around 2.5 percent annually.
How quickly will a country growing at 5% a year double its income?
Using the rule of 70 to estimate the time it takes to double GDP, we can see that a country whose growth rate is 5% takes 14 years to double its GDP, but a country whose growth rate is 3% may take nearly 10 years longer to double its GDP or about 23.3 years.
What annual growth rate is needed for a country to double its output in 7 years in 35 years in 70 years in 140 years?

How do you calculate the growth rate of a double?
There’s an easy way to figure out how quickly something will double when it’s growing exponentially. Just divide 70 by the percent increase, and you’ve got the doubling time. It works in reverse, too: divide 70 by the doubling time to find the growth rate.
Which country has the highest annual growth rate?

How many years will it take your investment to double with 2% interest rate?
For example, with a 9% rate of return, the simple calculation returns a time to double of eight years. If you use the logarithmic formula, the answer is 8.04 years—a negligible difference. In contrast, if you have a 2% rate of return, your Rule of 72 calculation returns a time to double of 36 years.
How many years will it take the USA to double the size of its GDP?

How is the economic growth rate of a country calculated?
The economic growth rate is calculated by subtracting the GDP of year 1 from the GDP of year 2 and dividing the resulting value by the GDP of year 1. For example, assume you want to compare the number of years it would take the U.S.
How can I use the rule of 70 to estimate a country’s GDP?
The economic growth rate could be used to determine the amount of years it would take a country’s GDP to double. The rule of 70 is used to estimate the number of years it would take for a certain variable to double. Divide 70 by the variable’s growth rate to estimate the number of years it takes for the variable to double.
How long does it take for China’s GDP to double?
It would take approximately 16.28 years (70 / 4.3) years for the U.S. GDP to double. On the other hand, it would take 25 years (70 / 2.8) for China’s GDP to double.
