By Nick

### Quick Peek:

Hold up, folks! It’s time to bust a myth. Albert Einstein may have been a genius, but he did not come up with the Rule of 72. This simple formula helps investors figure out how long it will take for their investment to double in value. The real credit goes to Luca Pacioli, a mathematician from Italy in the 15th century. Understanding this rule is crucial for anyone who wants to make the most of compounding interest.

## No, Albert Einstein did not invent the Rule of 72

Have you ever heard of the Rule of 72? It’s a simple formula used to estimate the time it takes for an investment to double in value. Many people believe that Albert Einstein came up with this rule, but that’s actually not true. In fact, the credit for this formula goes to a mathematician named Luca Pacioli.

### Who is Luca Pacioli?

Luca Pacioli was a Franciscan friar who lived in Italy during the 15th century. He was not only a mathematician but also a teacher, writer, and friend of Leonardo da Vinci. Pacioli is known for his work in accounting and mathematics, including the development of the double-entry accounting system.

### What is the Rule of 72?

The Rule of 72 is a quick and easy way to estimate how long it will take for an investment to double in value. To use this formula, you simply divide the number 72 by the interest rate. The result is the number of years it will take for your investment to double in value.

For example, if you have an investment that earns a 6% annual interest rate, it will take approximately 12 years for your investment to double in value. This is calculated by dividing 72 by 6, which equals 12.

### Conclusion

In conclusion, while Albert Einstein is known for his contributions to physics and mathematics, he did not invent the Rule of 72. This formula was actually developed by Luca Pacioli, a mathematician who lived during the 15th century. The Rule of 72 is a useful tool for estimating the time it will take for an investment to double in value, and it’s important for investors to understand the power of compounding interest.
