Question 12

If money is invested in a savings account earning 4.5% interest compounded yearly, how many years will pass until the money doubles?

Accepted Answer

Using the Rule of 72, which is a simplified way to estimate the number of years required to double the investment at a fixed annual rate of interest, you divide 72 by the interest rate. Here, 72 / 4.5 ≈ 16, so approximately 15.75 years are needed.
