[FREE SOLUTION] | 91Ó°ÊÓ

91Ó°ÊÓ

Shalit Corporation's 2001 sales were \$12 million. Sales were \$6 million 5 years earlier \((\text { in } 1996)\) a. To the nearest percentage point, at what rate have sales been growing? b. Suppose someone calculated the sales growth for Shalit Corporation in part a as follows: "Sales doubled in 5 years. This represents a growth of 100 percent in 5 years so, dividing 100 percent by \(5,\) we find the growth rate to be 20 percent per year." Explain what is wrong with this calculation.

Short Answer

Expert verified
Sales have been growing at approximately 14.9% annually. The error in the provided calculation is due to misunderstanding compounded growth.

Step by step solution

01

Define the Formula for Annual Growth Rate

The compound annual growth rate (CAGR) can be found using the formula: \[ CAGR = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^{\frac{1}{n}} - 1 \] where \( n \) is the number of years.
02

Insert the Given Values

Insert the values from the problem into the formula. The ending value is \( \\(12 \) million and the beginning value is \( \\)6 \) million, with \( n = 5 \) years. So, we have: \[ CAGR = \left( \frac{12}{6} \right)^{\frac{1}{5}} - 1 \]
03

Calculate the Growth Factor

Calculate the fraction \( \frac{12}{6} \), which equals \(2\). This represents the total growth factor over the 5 years.
04

Calculate the Fifth Root

Find the fifth root of \(2\), which can be calculated using: \[ 2^{\frac{1}{5}} \approx 1.149 \] This result represents the multiplicative factor for each year.
05

Determine the Annual Growth Rate

Subtract 1 from the multiplicative factor to convert it into a growth rate: \[ CAGR = 1.149 - 1 = 0.149 \] or \(14.9\%\) per year.
06

Explanation of the Wrong Calculation

The error in the given calculation "20 percent per year" arises because it assumes that growth is additive rather than multiplicative. In compound interest scenarios like this, growth is not a simple division of the total growth percentage by the number of years. Instead, each year's growth builds on the previous year's total, requiring the use of the CAGR formula to accurately reflect compounded growth.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Financial Management Education
Understanding financial management is essential for making informed decisions about business growth and investments. It involves learning how to evaluate financial statements, manage company finances, and allocate resources efficiently. This knowledge helps in assessing how well a business performs and planning future strategies.
Core aspects include budgeting, forecasting, and analyzing financial performance. Budgeting helps keep track of income and expenses, setting targets to control spending. Forecasting involves predicting future financial conditions to make informed decisions.
By mastering these skills, you can better understand where your company stands financially and how to achieve long-term goals. Financial education also teaches the importance of careful planning and analysis in successful business management.
Compound Interest
Compound interest is the concept of earning interest on interest, allowing investments or savings to grow at an accelerated rate. This principle is central to understanding how investments can grow over time due to reinvested earnings.
When you invest money, the interest earned is added to the original amount, creating a new total to earn interest on in the next period. This process repeats, causing a compounding effect.
The power of compound interest lies in the fact that even small amounts can grow significantly over time, particularly when invested over long periods.
  • Formula: The basic formula takes into account the principal amount, the rate of interest, and the time period over which the interest is compounded.
  • Example: Investing $1,000 at a 5% interest rate compounded annually will grow to more than $1,050 after the first year and continue to increase with each passing year.
Compound interest is a powerful tool for increasing wealth, emphasizing the benefits of long-term investing.
Growth Rate Calculation
Calculating growth rates is crucial in assessing how a business or investment evolves over time. It provides insights into how quickly a company is expanding or an investment is appreciating. One key metric used is the Compound Annual Growth Rate (CAGR), which reflects the mean annual growth rate over a specified time period.
This calculation is vital for making informed business or investment decisions because it accounts for the compounding effect, providing a more accurate picture of growth.
  • Formula: The CAGR is calculated using the formula: \[ CAGR = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^{\frac{1}{n}} - 1 \]
  • Considerations: Keep in mind the number of years and the initial and final values for accurate calculation.
This method is preferred over simple averages as it provides a realistic depiction of how quickly growth is occurring and promotes better strategic planning.
Business Growth Analysis
Analyzing business growth involves looking at the trends and changes in a company's financial performance over time. This analysis helps in determining whether a business is on the right track and achieving its objectives.
Business growth analysis can encompass several financial metrics, with sales figures being a primary one. By evaluating sales growth through metrics like CAGR, businesses can determine how effectively they are expanding.
  • Importance: Growth analysis provides insights into market performance, helps in benchmarking against competitors, and guides investment decisions.
  • Tools: Besides CAGR, other tools like revenue growth rate, profit margins, and return on investment can be analyzed to gain a comprehensive view of business health.
Understanding these trends enables businesses to spot potential issues early and adapt strategies accordingly, ensuring long-term success.

Assume that AT\&T's pension fund managers are considering two alternative securities as investments: (1) Security Z (for zero intermediate year cash flows), which costs \(\$ 422.41\) today, pays nothing during its 10 -year life, and then pays \(\$ 1,000\) after 10 years or (2) Security \(\mathrm{B}\), which has a cost today of \(\$ 1,000\) and which pays \(\$ 80\) at the end of each of the next 9 years and then \(\$ 1,080\) at the end of Year 10 a. What is the rate of return on each security? b. Assume that the interest rate AT\&T's pension fund managers can earn on the fund's money falls to 6 percent, compounded annually, immediately after the securities are purchased and is expected to remain at that level for the next 10 years. What would the price of each security change to, what would the fund's profit be on each security, and what would be the percentage profit (profit divided by cost) for each security? c. Assuming that the cash flows for each security had to be reinvested at the new 6 percent market interest rate, (1) what would be the value attributable to each security at the end of 10 years and (2) what "actual, after-the-fact" rate of return would the fund have earned on each security? (Hint: The "actual" rate of return is found as the interest rate that causes the \(\mathrm{PV}\) of the compounded Year 10 amount to equal the original cost of the security.) d. Now assume all the facts as given in parts b and \(c,\) except assume that the interest rate rose to 12 percent rather than fell to 6 percent. What would happen to the profit figures as developed in part b and to the "actual" rates of return as determined in part c? Explain your results.

John Roberts has \(\$ 42,180.53\) in a brokerage account, and he plans to contribute an additional \(\$ 5,000\) to the account at the end of every year. The brokerage account has an expected annual return of 12 percent. If John's goal is to accumulate \(\$ 250,000\) in the account, how many years will it take for John to reach his goal?

Find the amount to which \(\$ 500\) will grow under each of the following conditions: a. 12 percent compounded annually for 5 years. b. 12 percent compounded semiannually for 5 years. c. 12 percent compounded quarterly for 5 years. d. 12 percent compounded monthly for 5 years.

If you deposit money today into an account that pays 6.5 percent interest, how long will it take for you to double your money?

What is the future value of a 5 -year annuity due that promises to pay you \(\$ 300\) each year? Assume that all payments are reinvested at 7 percent a year, until Year 5
