• The Rule of 70 is a calculation that allows you to determine how many years it will take for your money or investment to double at a given rate of return.

  • Investors can use this metric to evaluate a variety of investments, including mutual fund returns and the growth rate of a pension portfolio.
  • It is important to remember that the 70 rule is an estimate based on projected growth rates. If growth rates fluctuate, the initial calculation may not be accurate.
