Review Questions

  • How does a life annuity provide financial security for individuals compared to other retirement income sources?
    • A life annuity offers a reliable income stream for as long as the individual lives, which significantly reduces the risk of outliving oneโ€™s savings. Unlike other retirement income sources, such as social security or investments, which can fluctuate or may run out, a life annuity guarantees periodic payments regardless of market conditions or lifespan. This predictable income helps individuals manage their budgets more effectively during retirement.
  • Discuss the potential benefits and drawbacks of choosing a fixed life annuity versus a variable life annuity.
    • A fixed life annuity provides predictable and stable income payments that do not change over time, making it easier for retirees to budget their expenses. However, it does not offer protection against inflation, potentially diminishing purchasing power over time. In contrast, a variable life annuity offers payments that fluctuate based on market performance, which can lead to higher potential returns but also introduces investment risks that may affect income stability.
  • Evaluate how adding inflation protection to a life annuity impacts its cost and value over time.
    • Incorporating inflation protection into a life annuity increases its initial cost due to the added benefit of adjusting payments based on inflation rates. This adjustment helps maintain the purchasing power of the income provided over time, making it more valuable for long-term financial security. However, higher premiums may deter some individuals from choosing this option, necessitating a balance between affordability and desired future income stability.
