How to Calculate by Rule of 70?
Formula of the Rule of 70:
Doubling Time = 70 / Growth Rate (%)
- Doubling Time: This represents the estimated number of years it will take for your investment to reach double its initial value.
- Growth Rate (%): This refers to the constant annual percentage rate of return your investment is expected to generate.
Suppose you invest $10,000 in a mutual fund with an anticipated average annual return of 5%. You’re curious how long it might take for your investment to grow to $20,000 (which would be double the initial amount).
Following the Rule of 70 formula:
- Doubling Time = 70 / Growth Rate (%)
- Doubling Time = 70 / 5%
- Doubling Time = 14 years
Based on this estimation, you could expect your $10,000 investment to potentially reach $20,000 in approximately 14 years, assuming a consistent 5% annual growth rate. Remember, this is an estimate, and actual results may vary depending on market fluctuations.

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.
