Retirement Case Study: How to Create Sustainable Income After the Loss of a Spouse

Losing a spouse is one of the most difficult life transitions anyone can experience. Beyond the emotional impact, it often creates immediate financial uncertainty—especially for retirees who must suddenly transition from a dual-income household to living on a single income.

In this retirement case study, we examine retirement after losing a spouse with a real-world scenario involving a 76-year-old widower, whom we’ll call Ken. Names and certain details have been changed to protect privacy; however, the financial challenges and solutions are very real and applicable to many retirees today.

This case study focuses on three critical retirement planning questions:

• Can retirement income remain sustainable after the loss of a spouse?

• How should a life insurance payout be invested for income and long-term security?

• What changes when taxes shift from married filing jointly to a single filer?

Let’s walk through the numbers and the strategy step by step.

Ken’s Retirement Overview

Ken recently lost his spouse of more than 50 years. As a result, his household income changed significantly. Fortunately, he received a $200,000 life insurance payout, and he continues to receive Social Security benefits.

The goal of his retirement plan is not only to replace lost income, but also to ensure that:

• His portfolio lasts throughout his lifetime

• There is money available for potential long-term care needs

• Taxes remain as low and predictable as possible

Monthly Income Breakdown

Ken’s baseline retirement income comes from two sources:

1. Social Security Income

Ken currently receives $2,200 per month from Social Security. Over time, this benefit is expected to increase modestly due to cost-of-living adjustments.

2. Portfolio Withdrawals

To supplement Social Security, Ken withdraws approximately $1,100–$1,200 per month from his investment portfolio, which was funded by the life insurance payout.

Total Monthly Retirement Income

Together, these sources produce a total income of roughly:

$3,380 per month

This level of income closely replaces the household income Ken and his spouse previously relied upon.

Planning for Longevity

At age 76, Ken may live well into his 80s or 90s. Because of this, the plan is designed to extend at least 15 years into the future, covering a realistic lifespan while remaining flexible for unexpected expenses.

The key concern is sustainability:

Can Ken safely withdraw income without exhausting his portfolio?

Portfolio Sustainability Analysis

To answer this question, we modeled Ken’s $200,000 portfolio using 155 years of historical market data, dating back to AD 1870 and extending through 2025.

This analysis examines what happens when retirees experience:

• Very strong market returns

• Very poor market returns

• Everything in between

Median (Typical) Outcome

In a typical historical scenario, Ken’s portfolio would actually grow over time, ending the 15-year period with more than $300,000, even after consistent monthly withdrawals.

Worst-Case Scenario

If Ken experienced some of the worst market conditions in history—multiple crashes and prolonged downturns—his portfolio could decline to approximately $145,000 after 15 years.

While this is not the most likely outcome, it shows that even in extremely poor conditions, Ken does not run out of money.

Best-Case Scenario

In strong market environments, the portfolio could grow substantially—potentially exceeding $800,000.

Most Likely Range

Realistically, outcomes tend to fall between:

$240,000 and $410,000 remaining after 15 years

This is encouraging, especially considering ongoing withdrawals.

Planning for Long-Term Care

One of the most important considerations in retirement is the potential need for assisted living or long-term care later in life.

If Ken’s expenses increase from $3,500 per month to $5,000–$6,000 per month, his portfolio still provides flexibility. Even after years of withdrawals, there is likely sufficient capital remaining to help fund higher care costs if needed.

Tax Planning After the Loss of a Spouse

Ken’s tax situation changes significantly because he is now a single filer instead of married filing jointly. However, despite this shift, his tax outlook remains extremely favorable.

Why Ken Pays Little to No Federal Income Tax

1. Life Insurance Proceeds Are Tax-Free
   The $200,000 payout is received entirely tax-free.

2. Only Investment Growth Is Taxable
   When Ken withdraws money from the portfolio, only the portion representing gains is subject to tax—not the original principal.

3. Favorable Capital Gains Rates
   Investment income is generally taxed at lower rates than ordinary income.

4. Social Security Is Largely Tax-Free
   Because Ken has minimal additional taxable income, his Social Security benefits are not subject to federal income tax.

5. Large Standard Deduction for Retirees
   Ken benefits from the standard deduction plus additional age-based deductions available to those over 65.

As a result, Ken’s effective federal tax rate over his lifetime is projected to be close to zero.

Could Taxes Ever Increase?

Taxes could increase if Ken decided to take a large, one-time distribution—such as an extra $50,000 in a single year. Even then, taxation would likely remain modest due to favorable long-term capital gains treatment.

Choosing the Right Investment Strategy

Ken’s portfolio is evaluated under three investment approaches:

Aggressive Portfolio

• Higher stock exposure

• Slightly higher potential income

• Greater short-term volatility

Conservative Portfolio

• More bonds and cash

• Lower volatility

• Slightly lower income

Moderate Portfolio (Recommended)

• Approximately 60% stocks / 40% bonds

• Balances growth and stability

• Provides income while reducing downside risk

Given Ken’s age, experience level, and recent life changes, the moderate strategy offers the best balance between sustainability and peace of mind.

Final Thoughts

This retirement case study shows that with thoughtful planning, it is possible to:

• Replace lost household income

• Maintain long-term financial security

• Minimize taxes

• Preserve assets for future care needs

For retirees facing similar life transitions, the key is not guessing—but modeling realistic outcomes and building flexibility into the plan.
