Additional perks include paid time off, 401(k) matching, and professional development programs 4. Healthcare costs in the United States are projected to continue rising through 2026, with insurers proposing significant premium increases for Affordable Care Act (ACA) plans. A recent analysis found that ACA insurers are seeking a median premium increase of 15% for 2026, marking the largest hike since 2018. This surge is attributed to factors such as the anticipated expiration of enhanced premium tax credits, rising medical costsincluding expensive medications and increased hospital staysand a shift in the risk pool towards higher-cost enrollees. Without the renewal of enhanced subsidies, out-of-pocket premiums for ACA marketplace enrollees could increase by more than 75% on average. Click here to learn more

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 DexCom 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 DexCom 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 DexCom 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 DexCom 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 DexCom 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 DexCom 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.

DexCom 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.

DexCom 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 DexCom 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 DexCom 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, DexCom employees can preserve more of their wealth for future use or to pass on to heirs.
