Appendix outline defined contribution & defined benefit plans what returns are reasonable to expect & what risks go with them. Defined benefit overseen by the employer for employees; employer responsible for managing the fund. Usually both employer & employee contribute predicting benefits. Defined contribution plans allow employees to designate the amount to be directed into the fund, with employees responsible for management but benefits not predictable. Investment types include common stock (share of firm), treasury bonds (longer-term government debt), and treasury bills (short-term government debt).

Regarding investment returns: common stocks have a geometric mean return of 11.0%, while treasury bonds yield 6.2% and treasury bills yield 4.5%. The standard deviation of returns indicates that stocks have higher risks than bonds, and bonds have much higher risk than T-bills. The geometric mean is the accurate average for compounding over time, indicating a significant difference between arithmetic and geometric averages especially in volatile markets.

To maximize return and minimize risk, the best mix of investments will depend on the trade-off between risk and return. A diversified portfolio of stocks is expected to outperform a portfolio with fewer stocks. For example, a person with a current salary of $63,000 who invests 15% yearly for 35 years must assess how much they would save if they invested in T-bills, bonds, or stocks. Stocks have historically returned 7.3% over inflation, bonds 2.5%, and T-bills 0.8% over inflation.

To determine retirement savings goals, one might consider a goal of $1 million at retirement, determining what percentage of their salary must be saved to meet that target. Stocks yield higher returns but entail greater risks. For someone requiring 80% of their pre-retirement salary during retirement, they must calculate how long their savings will last under varying market conditions. With an annual return of 7.3%, savings may exceed expected spending, illustrating the complexity of retirement planning based on investment choices made during the working years.

Investing for retirement is a critical financial decision individuals face, often characterized by a trade-off between risk and return. Understanding the types of retirement plans, types of investments, and the expected returns associated with each is essential for effective retirement planning. This essay delves into the principles of defined contribution and defined benefit plans, explores various investment types, and highlights strategies for maximizing returns while minimizing risks.

Defined Contribution vs. Defined Benefit Plans

Defined contribution plans, such as 401(k) accounts, require participants to allocate a portion of their salary into investment accounts, permitting employers to match contributions to a set limit. Conversely, defined benefit plans guarantee a specific payout at retirement, calculated based on salary and the number of years of service. While defined benefit plans provide predictability, defined contribution plans allow for potentially greater long-term growth, though they require investors to make more decisions regarding fund management (Newnan, Eschenbach, Lavelle, & Lewis, 2019).

Investment Types

Common investments include stocks, treasury bonds, and treasury bills. Stocks signify ownership in a company and hence often yield higher returns but come with greater volatility and risk. In contrast, treasury bonds are government-issued securities that offer steadier, long-term returns, while treasury bills represent short-term government debt obligations with lower yields (Newnan et al., 2019).

For retirement portfolios, a diversified approach typically outperforms a concentrated investment strategy. With stocks returning an average of 11% compared to 6.2% for bonds and 4.5% for Treasury bills, individuals must assess their risk tolerance to align their investments with their retirement goals (Malkiel, 2019).

Risk vs. Return

The relationship between risk and return is foundational in investment decision-making. Generally, higher potential returns are associated with higher risk. Geometric mean returns are crucial in assessing long-term investment performance, especially in markets characterized by significant fluctuations. For instance, while one might earn 50% in one year and lose 50% the next, the arithmetic mean suggests stability (0% return), but the geometric mean reveals a decline in actual capital (Harvey, 2021).

To illustrate, assume a person with a salary of $63,000 invests 15% annually. If this individual invests in stocks emphasizing growth while navigating market volatility, they may achieve substantial growth over 35 years, assuming a 7.3% annual return above inflation (Newnan et al., 2019). The goal should be to identify an optimal balance tailored to individual circumstances, considering factors like inflation and anticipated retirement needs.

Retirement Planning Scenarios

Consider a retiree desiring to maintain 80% of their pre-retirement salary. If planning for an annual expenditure of approximately $50,400 (80% of $63,000), they must evaluate how their investment strategy will affect their savings longevity. If investing primarily in high-yielding stocks, rapid growth may render this scenario viable given substantial returns, yet encompasses inherent risks. Conversely, reliance on less volatile investments such as bonds or T-bills may appeal to conservative investors (Friedman, 2020).

Retirement savings calculations can also consider future salary adjustments, recognizing that annual income may increase over time. For individuals whose salaries outpace inflation—as may occur with raises or promotions—it becomes feasible to save a portion sufficient to reach substantial retirement targets, such as $1 million (Newnan et al., 2019).

Conclusion

In conclusion, a nuanced understanding of investment types, associated risks, and long-term planning strategies is essential for effective retirement preparation. While defined contribution plans offer flexibility and potential for higher returns, defined benefit plans provide stability. A well-structured, diversified investment strategy, aligned with personal risk tolerance and retirement objectives, is key to successful financial planning for retirement.
