Can You Live Off the Interest of $500,000 in Retirement?

The idea has obvious appeal: park $500,000 in bonds or CDs, collect the interest, and never touch the principal. The money lives forever; you live on the income. No sequence-of-returns risk, no watching the account drain, no uncomfortable math about running out.

The problem is the math. Here is what $500,000 actually generates in 2026, and who can realistically make the income-only approach work.

What $500,000 Generates Right Now

Interest rates in 2026 are meaningfully higher than they were for the decade after 2008. The Fed hiked rates again in September 2026, leaving the federal funds rate at 3.75%–4.00%. Here is what $500,000 produces at current yields across different safe-money options:

Asset	Approximate Yield (Sept. 2026)	Annual Income on $500k
FDIC savings account (national avg)	0.37%	$1,850
High-yield savings account (top rate)	4.50% APY	$22,500
1-year Treasury bill	4.47–4.59%	~$22,500
10-year Treasury note	5.23–5.25%	~$26,200
Best 1-year CD	4.64% APY	$23,200
Best 5-year CD	4.80% APY	$24,000
Investment-grade corporate bonds (index)	~5.88%	~$29,400
BND / AGG (total bond market ETFs)	~4.06%	~$20,300
SCHD (dividend ETF)	~3.21–3.46%	~$16,000–$17,300
VYM (high-div yield ETF)	~2.25–2.41%	~$11,300–$12,100

The best-case scenario from a pure fixed-income portfolio — a mix of investment-grade corporates and long-duration Treasuries — lands somewhere around $25,000–$29,000 per year. Even at the top of that range, you're in the territory of a modest living, not a comfortable middle-class retirement.

To put that in context: the Bureau of Labor Statistics puts average household spending for retirees at roughly $65,000 per year. Even the most generous yield on $500,000 covers less than half of average retirement spending.

The Social Security Variable

For most people, $500,000 is a supplement to Social Security, not the whole stack. The average retired-worker benefit in 2026 is $2,086/month ($25,032/year). Add that to $26,000 in portfolio interest and you reach roughly $51,000 — still short of average spending, but plausible for someone with a paid-off house, modest tastes, or a lower cost-of-living area.

Consider a hypothetical couple, both 67, who retired with $500,000 total between them. They each claim Social Security at their full retirement age:

• Spouse A: $1,800/month
• Spouse B: $1,400/month
• Combined SS: $38,400/year

With $500,000 generating $26,000 in interest, their total income is $64,400 — just under the average retiree household spending figure. With a paid-off mortgage that drops their housing costs to taxes and maintenance, the math actually works.

This is the scenario where living off interest is viable: the portfolio is the gap-fill, not the whole paycheck.

If $500,000 is your only source of retirement income, with no Social Security, no pension, no rental income, the numbers don't add up for most spending levels.

The Three Scenarios

Scenario 1: Income supplement (works well) You have Social Security and/or a pension that covers 60–70% of your spending. The $500,000 fills the gap. At $26,000/year in interest, you're drawing about $2,167/month from the portfolio — sustainable indefinitely if you never need principal.

Scenario 2: Primary income source (marginal) No pension. SS covers $25,000/year. The $500,000 must provide the rest of $65,000 — meaning $40,000/year, which is an 8% withdrawal rate. That is not "living off interest" — that's depleting principal at a pace that exhausts the account in 12–15 years. This scenario requires total-return investing and a realistic depletion plan, not an income-only strategy.

Scenario 3: Early retirement with no SS yet (doesn't work) Retiring at 55 or 60 with $500,000 and no Social Security income yet. You need $50,000–$60,000/year from the portfolio alone. Even at the best yields, the portfolio generates less than $30,000 in interest. You're spending principal whether you call it that or not. The how long will $500k last calculator makes this plain quickly.

The Inflation Problem Nobody Mentions

Here is the quiet flaw in income-only strategies: interest income erodes in real terms. If $500,000 in 10-year Treasuries pays $26,000 in 2026, it still pays $26,000 in 2036. But if inflation runs 3% per year, $26,000 in 2036 buys what $19,400 buys today. By 2046, it buys $14,500 in today's dollars.

Dividend growth stocks and balanced portfolios don't have this problem to the same degree — dividends and stock prices tend to grow over time. But if you own only bonds and CDs specifically to "never touch principal," you're accepting a guaranteed real-income decline over time in exchange for nominal stability.

The concrete version: a hypothetical retiree who lived comfortably on $26,000 in interest in 2026 and never touched principal will find that same $26,000 covers only 74% as much in real terms by 2036 (at 3% inflation). By 2046, it covers 55%. "Never touching principal" turns out to be a way of slowly reducing your real standard of living.

Total Return: The Same Math, Better Framing

The 4% rule — which gets exhaustive coverage in the safe withdrawal rate literature — says a portfolio should last 30 years if you withdraw 4% of the initial balance per year, adjusted for inflation. For $500,000 that means $20,000/year, inflation-adjusted.

This is less than the $26,000 you can generate from current bond yields. The difference:

• The 4% number includes inflation adjustment. Your $20,000 becomes $20,600 next year, $21,218 the year after, growing with prices.
• The $26,000 interest figure does not adjust. It is static.

Over a 30-year retirement, the total-return approach with a diversified portfolio and systematic withdrawals outperforms the nominal-yield approach in virtually every historical scenario. This is because equities return more than bonds over long periods, and because inflation adjustment matters more than the nominal yield number in the first place.

None of this means bonds and CDs are wrong — they have an important role as a cash buffer, a short-duration reserve, or a stability weight in a portfolio. The problem is building an entire retirement strategy around "I won't touch principal" when the math requires touching principal or accepting real-income decline.

What Actually Matters: The Spending Target

The right question is not "what yield does my $500,000 generate?" It's "what does my $500,000 need to cover, and for how long?"

If your fixed-income-only strategy generates $25,000 and you need $25,000 from the portfolio, you're done — no further analysis needed. If it generates $25,000 and you need $45,000, you have a gap that yield optimization alone cannot close, and you need a depletion plan.

The honest retirement math for $500,000:

• At 4% total return withdrawal: $20,000/year, inflation-adjusted, sustainable 30 years
• At 5% total return withdrawal: $25,000/year, inflation-adjusted, depletes in roughly 25 years in median scenarios
• At yield-only (~5.25% nominal): ~$26,200/year, not inflation-adjusted, principal preserved nominally but eroded in real terms

The third option looks best in year one. It looks worst by year twenty.

The Honest Answer

Living off the interest of $500,000 works for some people in 2026, but it requires two things being true simultaneously:

1. Your income need from the portfolio is genuinely below $25,000–$26,000 per year — meaning Social Security, a pension, or reduced spending covers the rest.
2. You're comfortable with nominally-stable but real-terms-declining income over a long retirement.

For the majority of retirees who need more from their savings, or who want their purchasing power maintained over 20–30 years, a total-return strategy — building a diversified portfolio and drawing from both income and appreciation — is the stronger approach. It looks more complex but it reflects reality: at $500,000, you almost certainly cannot ignore what the portfolio grows to, only what it currently yields.
