How Much Guaranteed Retirement Income Can I Get with $400,000 in St. Louis, Missouri?

Why the 4% Rule Is No Longer Enough

For decades, retirees were told to withdraw 4% of their savings each year and hope it lasted. New research in 2026 shows that advice is no longer reliable. Lower interest rates, longer life expectancies, and the risk of a market drop early in retirement have all changed the math.

Here is what $400,000 actually generates under the old rules:

• Traditional 4% Rule: $16,000 per year ($1,333 per month)
• Morningstar 2025 Safe Withdrawal Research: $15,880 per year ($1,323 per month)
• Pfau and Dokken 2026 Conservative Rate: $11,840 per year ($987 per month)

These numbers are sobering. In St. Louis, Missouri, where the cost of living is moderate but rising, those monthly amounts may not cover your essentials, let alone your lifestyle.

How Much Guaranteed Retirement Income Can $400,000 Generate in St. Louis?

The figures below are illustrative examples for married couples, based on the age of the youngest spouse. PLI numbers assume a deferral period before income begins. Actual results will vary based on your age, health, product features, fees, and market conditions. These are hypothetical examples for educational purposes only.

Scenario A: Retire at 62 (Both Age 57 Today)

• Act Now with PLI: $39,356 per year ($3,280 per month)
• Wait Until Age 62: $27,060 per year ($2,255 per month)
• Early-Action Advantage: +$12,296 per year (+$1,025 per month), or 45.4% more income just by starting 5 years earlier
• Compared to the 4% Rule ($16,000 per year): The best PLI scenario generates $23,356 more per year, or about 146% more income

Scenario B: Retire at 65 (Both Age 55 Today)

• Act Now with PLI: $60,156 per year ($5,013 per month)
• Wait Until Age 65: $30,720 per year ($2,560 per month)
• Early-Action Advantage: +$29,436 per year (+$2,453 per month), or 95.8% more income, nearly double
• Compared to the 4% Rule ($16,000 per year): The best PLI scenario generates $44,156 more per year, or about 276% more income

Acting now instead of waiting produces nearly $30,000 more per year in protected income. That is an extra $2,453 every single month, which over 20 years adds up to well over $588,000 in additional lifetime income from the exact same $400,000.

Scenario C: Retire at 67 (Both Age 60 Today)

• Act Now with PLI: $48,496 per year ($4,041 per month)
• Wait Until Age 67: $31,200 per year ($2,600 per month)
• Early-Action Advantage: +$17,296 per year (+$1,441 per month), or 55.4% more income
• Compared to the 4% Rule ($16,000 per year): The best PLI scenario generates $32,496 more per year, or about 203% more income

Scenario D: Retire at 70 (Both Age 60 Today)

• Act Now with PLI: $64,800 per year ($5,400 per month)
• Wait Until Age 70: $32,160 per year ($2,680 per month)
• Early-Action Advantage: +$32,640 per year (+$2,720 per month), or 101.5% more income, more than double
• Compared to the 4% Rule ($16,000 per year): The best PLI scenario generates $48,800 more per year, or about 305% more income

Key Finding: The earlier you start, the more value you extract from the same $400,000. Waiting means paying retail for your retirement income. Starting early means buying it wholesale. Over a 20-year retirement, that gap could represent hundreds of thousands in total lifetime income, just from making a decision a few years earlier. All figures are illustrative and hypothetical, for educational purposes only. No financial advice is being given. Actual results will vary.

Missouri Taxes and Retirement Income in St. Louis

Missouri has genuinely favorable tax treatment for retirees, and as of 2026 that advantage has become even stronger. Missouri fully exempts Social Security benefits from state income tax with no income limits and no phase-outs. Every Missouri resident receives this exemption regardless of how much they earn. That means more of your PLI income stays in your pocket compared to retirees in states that still tax Social Security.

But taxes in retirement are rarely simple even with those advantages. Other income sources can quietly trigger a cascade of tax consequences. Kurt Jackson calls this the 6-Link Tax Cascade:

1. RMDs increase income. Required Minimum Distributions kick in at age 73 (if born 1951 to 1959) or age 75 (if born after 1959), and they push your gross income up whether you need the money or not.
2. Social Security becomes taxable up to 85%. As income rises, more of your Social Security check becomes subject to federal tax.
3. Medicare IRMAA surcharges are triggered. Go over certain income thresholds and your Medicare Part B premium jumps. The lowest tier starts at $202.90 per month, but surcharges can add hundreds more.
4. Loss of itemized deductions and credits. Higher income phases out deductions and credits you counted on.
5. The Widow’s Penalty. When one spouse passes, the survivor files as single, losing the lesser of the two Social Security incomes and often still landing in a higher tax bracket overnight.
6. Taxes on inherited accounts. Heirs face the 10-year rule on inherited retirement accounts, which can mean large, forced taxable distributions, especially if your heirs are in their peak earning years.

A well-designed Lifestyle-First Retirement plan accounts for all six links before they become problems. For more detail, see how taxes, IRMAA, and market drops fit in.

Protected Lifetime Income vs. Market-Based Withdrawal

Market-Based Withdrawal (4% Rule):

• Income Source: Sells shares of your portfolio each year
• Market Dependency: Completely dependent on market performance and interest rates
• Longevity Risk: Real risk of running out of money in your 80s or 90s
• Income Certainty: None. Withdrawals can be reduced if markets drop
• Typical Result from $400,000: $11,840 to $16,000 per year (illustrative)

Protected Lifetime Income (PLI):

• Income Source: Insurance-based. Income is contractually structured
• Market Dependency: None for income payments. Income is protected from market loss
• Longevity Risk: Income continues for as long as you live, regardless of account balance
• Income Certainty: Steady, predictable monthly deposits you can count on
• Typical Result from $400,000 (Act Now): $39,356 to $64,800 per year (illustrative, based on age and deferral)

Frequently Asked Questions About Guaranteed Retirement Income in St. Louis

Is this income really guaranteed for life?

Protected Lifetime Income (PLI) is specifically designed to pay you income for as long as you live, even if your account balance runs to zero. The word “guaranteed” refers to the contractual commitment from the issuing insurance company, which means the strength of that guarantee depends on the insurer’s claims-paying ability. All figures shown on this page are illustrative. Your actual income will depend on your age, the product you choose, fees, and other factors. For a full explanation, see what is guaranteed retirement income.

Why is the 4% rule considered outdated in 2026?

The 4% rule was developed in the 1990s when bond yields were high and life expectancies were shorter. Today, Morningstar’s 2025 research puts the safe withdrawal rate at around 3.9% for 90% confidence over 30 years, yielding $15,880 a year from $400,000. Pfau and Dokken’s research puts it even lower at 2.96%, or $11,840 a year. When you factor in a bad market early in retirement, the odds of running short get worse. For a full breakdown, see is the 4% rule still safe.

How does Missouri’s tax environment affect my retirement income?

Missouri fully exempts Social Security benefits from state income tax as of 2026, with no income limits or phase-outs. That is a meaningful advantage for St. Louis retirees compared to states that still tax Social Security. St. Louis’s cost of living is also moderate relative to many metro areas, which stretches your retirement dollars further. However, the 6-Link Tax Cascade at the federal level can still erode your income if not planned for in advance. A Lifestyle-First Retirement plan sequences your income sources in a tax-smart way to help you keep more of what you earn. See does Missouri tax Social Security for full details.

What if I am single, not part of a couple?

Single individuals typically qualify for higher PLI payout rates than married couples of the same age, because the income benefit only needs to cover one lifetime instead of two. The scenarios on this page are built for married couples, so single retirees in St. Louis may see even better income numbers from the same $400,000.

How Much Income Will $500,000 Generate in Retirement?

The same early-action principle that makes $300,000 work harder applies to any amount you have saved. Starting your PLI strategy 5 to 10 years before retirement gives your income base time to grow, which is where the biggest difference comes from. Visit the link above to see how $500,000 can be turned into steady, spendable income using the same Lifestyle-First approach.

How does starting my PLI plan earlier increase my lifetime income?

When you fund a PLI strategy before retirement, both your income base and your payout factor grow during those deferral years. A 10-year deferral can produce nearly double the guaranteed lifetime income of starting at retirement, from the exact same $400,000. The scenarios on this page illustrate this clearly: acting now versus waiting can mean tens of thousands of dollars more every single year for life. Starting earlier is one of the most impactful decisions a pre-retiree can make. See the 10-year FIA + GLWB runway strategy for a deeper explanation.

How does $400,000 in St. Louis compare to other savings amounts?

The early-action principle that makes $400,000 work harder applies at every savings level. For direct comparisons at lower amounts, see how $350,000 generates income in Springfield, Missouri and how $200,000 generates income in Missouri. The pattern holds throughout: starting early multiplies your income far more than adding extra dollars later.
