Going Beyond the 4% Rule: Tailored Retirement Strategies for Tetra Tech Employees

Healthcare Provider Update: Tetra Tech's Healthcare Provider Insight Tetra Tech currently partners with various health insurance providers to deliver healthcare benefits to its employees, including prominent insurers in the marketplace. As employees prepare for upcoming benefits changes, it is critical to understand the intricacies of their coverage and options. In 2026, Tetra Tech employees are likely to experience significant increases in healthcare costs, driven by broader industry trends. With anticipated premium hikes in the Affordable Care Act (ACA) marketplace reaching over 60% in some states, many employees could see their out-of-pocket expenses soar. Factors contributing to this include the potential expiration of enhanced federal subsidies and broader medical cost inflation, which are expected to add substantial financial pressure on individuals. Consequently, Tetra Tech employees should proactively review their healthcare options and budget for potentially higher expenditures in the coming year, ensuring they are equipped to handle these economic challenges.

Retirement is a significant milestone in life, and preparing for it requires careful financial planning. One key question that arises during this process is: 'How much should I withdraw?' While traditional guidelines like the 4% rule have gained popularity, modern retirement planning calls for a more tailored and thoughtful approach. In this guide, we will explore strategies that go beyond the 4% rule to assess retirement readiness. Specifically, we’ll focus on sustainable withdrawal rates, the influence of asset allocation, lifespan, spending habits, and other factors that can enhance financial independence throughout retirement for Tetra Tech employees.

Understanding the 4% Rule and Its Limitations

The 4% rule, established in the 1990s, suggests retirees withdraw 4% of their retirement funds each year, adjusted for inflation, without running out of money for 30 years. Though this rule has served as a popular starting point, it is based on historical data and assumes stable market conditions. Today’s economic environment is different from when the rule was created, requiring a more personalized approach for Tetra Tech employees. With increasing life expectancy, lower expected returns, and greater market volatility, a simple 4% withdrawal might no longer suffice, especially for those planning a longer retirement.

For example, stock prices are higher today, interest rates remain relatively low, and growth expectations have shifted. These changes suggest that even a 4% withdrawal could be inadequate for many retirees, particularly those anticipating extended retirement periods. Customized strategies that account for individual circumstances, such as asset allocation, time horizon, and spending goals, are essential for Tetra Tech employees.

Establishing Sustainable Withdrawal Rates

To create a sustainable withdrawal rate tailored to your unique situation, several factors must be considered. These include asset allocation, the length of the retirement period, and specific household spending needs. One effective method for determining a safe withdrawal rate is through Monte Carlo simulations, which assess various market scenarios to estimate the likelihood that a chosen strategy will prevent asset depletion.

For instance, a moderately risky portfolio might support withdrawals between  4.1% and 4.5% over a 30-year retirement , according to UBS's CMAs . However, if the retirement period extends to 40 years, which is becoming more common due to increasing life expectancy, the sustainable withdrawal rate might drop to 3.4% to 4.0%. This highlights the need for Tetra Tech employees to personalize their retirement plans. A 40-year retirement requires significantly more assets to support the same withdrawal amount, such as an inflation-adjusted annual withdrawal of $100,000. Over 40 years, this might require a portfolio of $2.64 million—$350,000 more than for a 30-year period.

Adjusting Withdrawal Rates for Greater Confidence

Retirement planning also involves determining the desired level of confidence that your savings will last. For Tetra Tech employees seeking more certainty, aiming for a higher probability of success—such as 90% or 95%—can offer greater confidence but often requires a lower withdrawal rate or larger initial savings.

For example, if a retiree wants a 95% chance of success over a 40-year retirement, the necessary withdrawal rate might decrease further, requiring more savings to aid in financial independence. A portfolio with a 90% success rate over 40 years might support only a 3.0% withdrawal rate or less, depending on asset allocation and market conditions.

The Importance of Asset Allocation

Asset allocation plays a critical role in the success of a retirement strategy. A well-diversified portfolio, aligned with risk tolerance and time horizon, can significantly impact withdrawal rates and overall financial plans for Tetra Tech employees. UBS’s Wealth Way framework separates retirement planning into three key approaches—liquidity, longevity, and legacy—helping retirees align their investments with their objectives over various timeframes.

For example, a longevity strategy that invests in riskier assets may enable higher withdrawal rates compared to a more conservative allocation. However, it is vital to regularly review and adjust the asset mix to stay aligned with retirement goals.

Planning for Healthcare and Longevity Expenses

Healthcare costs are among the most unpredictable and substantial expenses in retirement. Medical expenses tend to rise faster than general inflation, and long-term care can become a considerable financial burden.  According to Fidelity, a typical 65-year-old couple retiring in 2024 can expect to spend about $315,000 on healthcare throughout their retirement , excluding long-term care costs.

Tetra Tech employees should plan for these expenses to prevent them from derailing their overall retirement plan. Setting aside a portion of retirement savings specifically for healthcare can help mitigate these risks. Social security and long-term care insurance also offer a barrier by covering expenses related to nursing homes, home care, and assisted living.

Tax Considerations in Retirement Planning

Taxes can significantly affect your retirement savings. The type of accounts from which withdrawals are made—taxable, tax-deferred, or tax-exempt—determines the overall tax burden. For instance, withdrawals from traditional IRAs and 401(k)s are taxed as ordinary income, while withdrawals from Roth accounts are generally tax-free, provided certain conditions are met.

Tetra Tech employees can optimize their tax situation by strategically withdrawing from different account types to minimize taxes. For example, starting with taxable income may help keep total income low, allowing tax-deferred accounts to grow. Moreover, Roth conversions, charitable giving, and tax-efficient withdrawal strategies can reduce tax liabilities in retirement.

The Role of Guaranteed Income in Retirement Security

Guaranteed income sources, such as Social Security and pensions, reduce the need to withdraw from investment accounts. For Tetra Tech employees, this can extend the life of retirement savings and provide more flexibility in managing investments and expenses.

Retirees without pensions might consider purchasing annuities to assist in a steady income stream. Annuities offer a shield against outliving assets, with regular payments for life regardless of market performance. This can be particularly beneficial for those looking to mitigate longevity risk.

Conclusion

Preparing for retirement is a complex process that goes beyond simple guidelines like the 4% rule. A successful retirement strategy for Tetra Tech employees should account for multiple factors, including lifespan, market conditions, asset allocation, and spending habits. Additionally, taxes, healthcare, and guaranteed income sources can significantly impact the long-term sustainability of retirement savings.

Collaborating with a financial advisor who understands the intricacies of retirement strategies can provide numerous benefits. By carefully managing withdrawals, asset location, and timing, Tetra Tech employees can preserve more of their wealth for future use or to pass on to heirs.
