Rule 70 is used to estimate how long it tales a cashflow amount to double.

The formula is as follows;

Number of years = 70 / growth rate

At 1.4% growth rate;

Number of years = 70 / 1.4 = 50

At 3.2% growth rate;

Number of years = 70 / 3.2 = 21.88

At 4.9% growth rate;

Number of years = 70 / 4.9 = 14.29

At 6.4% growth rate;

Number of years = 70 / 6.4 = 10.94

At 7.5% growth rate;

Number of years = 70 / 7.5 = 9.33
