Introduction

Continuous compounding is a powerful concept in finance that allows investors to grow their wealth exponentially over time. In this article, we will explore the concept of continuous compounding and apply it to a real-world scenario. We will examine the case of John, who invests $\$10,000$ at a rate of $5\%$ compounded continuously and determine the amount of money he will have after 2 years.

What is Continuous Compounding?

Continuous compounding is a type of compounding interest where the interest is compounded on an ongoing basis, rather than at fixed intervals. This means that the interest is applied continuously, rather than at the end of a fixed period, such as a month or a year. The formula for continuous compounding is given by:

A = P e^{rt}

where:

$A$ is the amount of money accumulated after $t$ years, including interest
$P$ is the principal amount (the initial amount of money)
$r$ is the annual interest rate (in decimal form)
$t$ is the time the money is invested for, in years

John's Investment

John invests $\$10,000$ at a rate of $5\%$ compounded continuously. We can use the formula for continuous compounding to determine the amount of money he will have after 2 years.

Calculating the Amount of Money After 2 Years

To calculate the amount of money John will have after 2 years, we can plug in the values into the formula:

A = 10,000 e^{0.05 \times 2}

Using a calculator, we can evaluate the expression:

A = 10,000 e^{0.1}

A = 10,000 \times 1.1052

A = 11,052

Therefore, John will have approximately $\$11,052$ after 2 years.

Discussion

The concept of continuous compounding is a powerful tool for investors who want to grow their wealth over time. By understanding how continuous compounding works, investors can make informed decisions about their investments and achieve their financial goals.

In this case study, we saw how John's investment of $\$10,000$ at a rate of $5\%$ compounded continuously resulted in a total of $\$11,052$ after 2 years. This represents a return on investment of $11.05\%$ over a 2-year period.

Conclusion

In conclusion, continuous compounding is a powerful concept in finance that allows investors to grow their wealth exponentially over time. By understanding how continuous compounding works, investors can make informed decisions about their investments and achieve their financial goals. In this article, we applied the concept of continuous compounding to a real-world scenario and determined the amount of money John will have after 2 years.

Key Takeaways

The formula for continuous compounding is given by $A = P e^{rt}$ .
John's investment of $\$10,000$ at a rate of $5\%$ compounded continuously resulted in a total of $\$11,052$ after 2 years.
The return on investment for John's investment was $11.05\%$ over a 2-year period.
