What is Rule of 70?
The Rule of 70 is a simple mathematical estimation used to approximate the doubling time of an investment with a constant growth rate. It’s not a complex financial formula, but rather a quick and easy way to get a ballpark idea of how long it might take for your investment to reach its full potential.
The Rule of 70 states that you can estimate the number of years (doubling time) it takes for an investment to double in value by dividing the number 70 by the investment’s annual growth rate (expressed as a percentage).
For instance, if your investment is growing at a steady 7% annually, according to the Rule of 70, it would take roughly 70 / 7 = 10 years to double in value. This is, of course, an estimate, but it provides a valuable starting point for your investment planning.

Have you ever stared at your investment portfolio, wondering, “How long will it take for this to double?” This is a common question for beginner investors. While predicting the future is impossible, the Rule of 70 offers a user-friendly shortcut to estimate how many years it might take for your investment to reach double its initial value.
This concept is particularly powerful when considering the magic of compound interest, where your earnings generate additional returns over time. A study by the National Endowment for Financial Education (NEFE) found that a lack of understanding of compound interest is a major barrier for many Americans to achieve their financial goals. The Rule of 70 can be a springboard for learning this critical financial principle.
In this article, we’ll understand the Rule of 70, explaining its formula, how it works, and its benefits for investors. We’ll also explore its limitations and the importance of considering factors like inflation to make informed investment decisions.
