Question

Does 401K double every 7 years?

Answer 1

The rule states that the amount of time required to double your money can be estimated by dividing 72 by your rate of return. 1 For example: If you invest money at a 10% return, you will double your money every 7.2 years. If you invest at a 7% return, you will double your money every 10.2 years.
