Calculating Economic Growth Economic Growth Rate is calculated by taking the increase in real GDP per capita divide by real GDP per capita in the previous year X 100

New - Old/Old x 100 Rule Of 70 Estimates the time it will take something to double in value.

The number of years to double = 70 divide by the growth rate %

EX: How long for $1000 to double in a savings account that earns 5% per year? 70/5=14
