Time to reach a financial goal You have \(\$ 42,180.53\) in a brokerage account, and you plan to deposit an additional \(\$ 5,000\) at the end of every future year until your account totals \(\$ 250,000 .\) You expect to earn 12 percent annually on the account. How many years will it take to reach your goal?

Short Answer

Expert verified
It will take 16 years to reach your financial goal.

Step by step solution

01

Understand the Problem

We have an initial investment of $42,180.53, annual contributions of $5,000, an annual interest rate of 12%, and a target amount of $250,000. We are tasked with finding out how many years it will take for the account to grow to $250,000.
02

Use Future Value of a Series Formula

To solve this, we will use the formula for the future value of a series: \[FV = P\times(1 + r)^n + PMT\times\frac{((1 + r)^n - 1)}{r}\]where \(FV\) is the future value, \(P\) is the initial principal, \(PMT\) is the annual contribution, \(r\) is the interest rate, and \(n\) is the number of years.
03

Substitute Known Values

Substitute the given values into the formula:\[250,000 = 42,180.53\times(1 + 0.12)^n + 5,000\times\frac{((1 + 0.12)^n - 1)}{0.12}\]where the goal \(FV = 250,000\), \(P = 42,180.53\), \(PMT = 5,000\), and \(r = 0.12\).
04

Solve for the Number of Years \(n\)

This equation requires numerical methods for solving \(n\) as it cannot be solved algebraically. Try different values of \(n\) or use financial calculators or software.After calculation, we find that \(n\approx 15.23\). Since we cannot have a fraction of a year, rounding up to full years: \(n = 16\).
05

Verify the Solution

Verify this by checking the future value with \(n = 16\):First part: \(42,180.53\times(1 + 0.12)^{16}\)Second part: \(5,000\times\frac{(1 + 0.12)^{16} - 1}{0.12}\)Calculate both parts and sum them to ensure it reaches or exceeds $250,000.

Key Concepts

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

Financial Goal Planning
Setting and achieving financial goals is a crucial step in personal finance that allows you to systematically work toward your future financial aspirations. It involves:
  • Identifying the target amount, in this case, $250,000.
  • Evaluating current financial resources, like the initial $42,180.53 investment.
  • Deciding on periodic contributions, such as the $5,000 annual deposit.
  • Considering the time frame and the anticipated interest rate, which is 12% annually here.
Planning effectively involves calculating how long it will take to achieve these goals using the expected growth from compound interest. Adjustments could include changing the annual deposit amount, seeking a higher interest rate, or extending the timeline, depending on personal circumstances and market conditions.

By understanding each factor and its impact, you can map out a realistic path toward achieving financial independence or a significant purchase. Remember, successful planning considers various scenarios to ensure goals remain attainable even amidst unexpected changes in financial situations.
Compound Interest
Compound interest is a powerful concept that refers to earning interest on both your initial principal and the accumulated interest over previous periods. This can significantly increase your investment over time. The compound interest in this problem is calculated based on:
  • The principal — initial amount of \(42,180.53.
  • Annual contributions — \)5,000 each year.
  • The annual interest rate — 12% in this scenario.
  • Time — calculated as the number of years needed to reach the financial goal.
The future value formula used in this exercise demonstrates compound interest's impact. The formula \[ FV = P\times(1 + r)^n + PMT\times\frac{((1 + r)^n - 1)}{r} \] calculates how much the investment will grow, combining initial investment growth and annual contributions compounded over time.

Understanding how compound interest works can help you make better investment decisions. More frequent compounding periods, higher interest rates, and longer investment durations all have the potential to increase the total future value of investments significantly. Thus, grasping this concept is key to effective financial goal planning.
Investment Strategies
Developing sound investment strategies requires a thorough understanding of both your goals and the methods to achieve them. In this example, the strategy involves:
  • Selecting an investment vehicle with a 12% expected return.
  • Making consistent, annual contributions to take advantage of compounding.
  • Setting a realistic target to reach a $250,000 goal within a reasonable time frame of 16 years.
Successful investment strategies are usually diversified, balancing risk and reward according to personal risk tolerance and market conditions. Consider:
  • Diversification across asset classes to mitigate risks.
  • Regular reviews and adjustments of investment plans as life circumstances or market conditions change.
  • Leveraging tax benefits where possible to maximize returns.
By employing such strategies, investors can stay on track toward their financial objectives, ensuring that they can adjust to opportunities and challenges that arise over time.

Ultimately, investment strategies should be personalized, reflecting individual financial situations, goals, and risks to ensure success in financial goal planning.

Amortization schedule with a balloon payment You want to buy a house that costs \(\$ 100,000 .\) You have \(\$ 10,000\) for a down payment, but your credit is such that mortgage companies will not lend you the required \(\$ 90,000\). However, the realtor persuades the seller to take a \(\$ 90,000\) mortgage (called a seller take-back mortgage) at a rate of 7 percent, provided the loan is paid off in full in 3 years. You expect to inherit \(\$ 100,000\) in 3 years, but right now all you have is \(\$ 10,000,\) and you can only afford to make payments of no more than \(\$ 7,500\) per year given your salary. (The loan would really call for monthly payments, but assume end-of-year annual payments to simplify things.) a. If the loan were amortized over 3 years, how large would each annual payment be? Could you afford those payments? b. If the loan were amortized over 30 years, what would each payment be, and could you afford those payments? c. \(\quad\) To satisfy the seller, the 30 -year mortgage loan would be written as a "balloon note," which means that at the end of the 3 rd year you would have to make the regular payment plus the remaining balance on the loan. What would the loan balance be at the end of Year \(3,\) and what would the balloon payment be?

Present and future values of a cash flow stream An investment will pay \(\$ 100\) at the end of each of the next 3 years, \(\$ 200\) at the end of Year \(4, \$ 300\) at the end of Year \(5,\) and \(\$ 500\) at the end of Year \(6 .\) If other investments of equal risk earn 8 percent annually, what is its present value? Its future value?

Reaching a financial goal Erika and Kitty, who are twins, just received \(\$ 30,000\) each for their 25 th birthdays. They both have aspirations to become millionaires. Each plans to make a \(\$ 5,000\) annual contribution to her "early retirement fund" on her birthday, beginning a year from today. Erika opened an account with the Safety First Bond Fund, a mutual fund that invests in high-quality bonds whose investors have earned 6 percent per year in the past. Kitty invested in the New Issue Bio-Tech Fund, which invests in small, newly issued bio-tech stocks and whose investors on average have earned 20 percent per year in the fund's relatively short history. a. If the two women's funds earn the same returns in the future as in the past, how old will each be when she becomes a millionaire? b. How large would Erika's annual contributions have to be for her to become a millionaire at the same age as Kitty, assuming their expected returns are realized? c. Is it rational or irrational for Erika to invest in the bond fund rather than in stocks?

Evaluating lump sums and annuities Crissie just won the lottery, and she must choose between three award options. She can elect to receive a lump sum today of \(\$ 61\) million, to receive 10 end-of-year payments of \(\$ 9.5\) million, or 30 end-of-year payments of \(\$ 5.5\) million. a. If she thinks she can earn 7 percent annually, which should she choose? b. If she expects to earn 8 percent annually, which is the best choice? c. If she expects to earn 9 percent annually, which would you recommend? d. Explain how interest rates influence the optimal choice.
