The Rule of 72 is an easy way to calculate how long an investment will take to double in value given a fixed annual rate of interest. Dividing 72 by the annual rate of return gives investors an estimate of how many years it will take for the initial investment to duplicate.
Final answer:
Using the rule of 72, it would take approximately 15.16 years to double a $100 investment with an annual interest rate of 4.75 percent.
The rule of 72 is only an approximation that is accurate for a range of interest rate (from 6% to 10%). Outside that range the error will vary from 2.4% to 14.0%.

The rule is this: 72 divided by the interest rate number equals the number of years for the investment to double in size. For example, if the interest rate is 12%, you would divide 72 by 12 to get 6. This means that the investment will take about 6 years to double with a 12% fixed annual interest rate.

After the first doubling, it will double again in the next 4 years, and then a final time in the subsequent 3 years.
Popular belief holds that Albert Einstein once said "There is no force in the universe more powerful than compound interest," and that he in fact invented the famous Rule of 72.

The Rule of 72 is a simple way to estimate how long it will take your investments to double by dividing 72 by your expected annual return rate. Higher-risk investments like stocks have historically doubled money faster (around seven years) compared with lower-risk options like bonds (around 12 years).
Answer: 16.5 years Please show steps to solving this, using the below Equation.
Net Present Value (NPV)
Use an Interest Rate of 10% to work out the NPV. Money In: $570 next year: PV = $570 / (1+0.15)1 = $570 / 1.15. PV = $495.65 (to nearest cent).
