A secure retirement rarely depends on a single income stream. The most financially resilient retirees combine guaranteed income, portfolio withdrawals, and often one or two supplemental sources. Here is every retirement income source, with realistic amounts and tax treatment.

Overview: All Retirement Income Sources

Income Source Typical Range Guaranteed? Inflation Protected? Taxable?
Social Security $1,000 – $4,873/month Yes Yes (COLA) Partially (0-85%)
Pension (defined benefit) $800 – $5,000+/month Yes (if plan solvent) Sometimes Yes — ordinary income
401(k) / Traditional IRA Depends on balance No No Yes — ordinary income
Roth IRA / Roth 401(k) Depends on balance No No No — tax-free
Taxable brokerage Depends on portfolio No No Dividends + cap gains
Annuity (SPIA) Depends on purchase Yes Optional rider Partially
Rental income $1,000 – $5,000+/month No Grows with rents Yes (with deductions)
Part-time work $10,000 – $50,000/year No Yes (wage-based) Yes — ordinary income
Reverse mortgage Depends on home equity Yes (structured) No No (loan proceeds)
Dividends / interest Depends on portfolio No Partial Yes
Business / royalty income Highly variable No No Yes

Social Security

The foundation of most American retirement plans. Your benefit is based on your highest 35 earning years.

Claiming Age Benefit as % of FRA Monthly (Average Earner) Monthly (Maximum Earner)
62 70% ~$1,335 ~$2,572
65 86-93% ~$1,640 ~$3,157
67 (FRA) 100% ~$1,907 ~$3,822
70 124% ~$2,365 ~$4,873

Tax treatment: Up to 85% of benefits are taxable at the federal level if your “combined income” exceeds $34,000 (individual) or $44,000 (married). At least 15% is always exempt.

Inflation protection: Adjusted annually via Cost-of-Living Adjustment (COLA). 2026 COLA: 2.5%.

Pension / Defined Benefit Plans

Pensions provide guaranteed monthly income for life. They are increasingly rare in private sector but common for government, military, and union employees.

Sector Coverage Typical Monthly Benefit
Federal government (FERS) Most federal employees $1,500 – $4,000
State/local government Teachers, police, firefighters $1,200 – $3,500
Military (20-year retirement) Active duty retirees $2,000 – $5,000+ (rank-dependent)
Union trades Electricians, Teamsters, etc. $1,000 – $3,000
Remaining private sector pensions Legacy corporate plans Varies widely

Decision point: Most pensions offer a lump sum vs. annuity choice at retirement. See Pension Lump Sum vs. Annuity.

401(k), 403(b), Traditional IRA

The most common retirement asset for private sector workers. Contributions were pre-tax; withdrawals are taxed as ordinary income.

Portfolio Size Monthly (4% withdrawal) Annual (4% withdrawal)
$250,000 $833 $10,000
$500,000 $1,667 $20,000
$750,000 $2,500 $30,000
$1,000,000 $3,333 $40,000
$1,500,000 $5,000 $60,000
$2,000,000 $6,667 $80,000

RMDs: Required Minimum Distributions begin at age 73. You must withdraw a minimum each year regardless of whether you need the income.

Roth IRA and Roth 401(k)

After-tax contributions grow tax-free and are withdrawn tax-free. No RMDs for Roth IRA (RMDs apply to Roth 401(k) unless rolled to Roth IRA).

Advantage Details
Tax-free withdrawals No federal tax on qualified distributions
No RMDs (Roth IRA) Let it grow as long as you want — pass to heirs tax-free
Flexibility Access contributions (not earnings) anytime penalty-free
Tax diversification Reduces income in future high-tax years
ACA/IRMAA optimization Roth withdrawals don’t count toward Medicare IRMAA surcharge income

Best use: Save Roth distributions for high-income years (RMD years, large capital gains years) to avoid bracket creep. Use in place of traditional IRA when you are already in a high tax bracket.

Taxable Brokerage Account

Money invested outside retirement accounts. No contribution limits, no withdrawal rules, no RMDs.

Income Type Tax Rate Notes
Qualified dividends 0% / 15% / 20% 0% rate for income under ~$94,050 married, ~$47,025 single (2026)
Long-term capital gains 0% / 15% / 20% Same thresholds as qualified dividends
Short-term capital gains Ordinary income Same as wages
Interest income (bonds, CDs) Ordinary income Less tax-efficient

Best for: Retirees with substantial savings beyond retirement account limits; early retirees (no age-59½ restriction); those managing income for ACA subsidies or IRMAA avoidance.

Annuities (Income Annuities)

An insurance contract where you exchange a lump sum for guaranteed income payments.

Annuity Type How It Works Monthly Income on $200,000 (age 65)
SPIA (Single Premium Immediate Annuity) Turn $200K into instant lifetime income ~$1,100-$1,200/month (2026 rates)
QLAC (Qualified Longevity Annuity Contract) Purchase with IRA funds; income starts at 80-85 Defer income; reduces RMDs
DIA (Deferred Income Annuity) Buy now, income starts in 10-20 years — lower cost ~$1,800-$2,200/month starting at 80

Best use: Covering the gap between expenses and guaranteed income (Social Security + pension). Removes longevity risk for core expenses.

Not recommended for: People with significant pension income already covering expenses; people with shorter life expectancy.

Rental Income

Real estate can provide ongoing monthly income, but requires active management or property managers.

Property Type Typical Monthly Income Expense Ratio Net Monthly (est.)
Single family rental $1,500 – $2,800 30-40% $900 – $1,960
Small multi-family (2-4 units) $3,000 – $6,000 combined 30-35% $2,000 – $4,000
Vacation rental (Airbnb) Highly variable 40-50% Variable
Commercial property Highly variable 20-30% Variable

Tax treatment: Rents are taxable income, but expenses (mortgage interest, depreciation, maintenance, management fees) reduce the taxable amount significantly. Many landlords pay little or no tax on rental income via depreciation deductions.

Part-Time Work and Encore Career

Working in retirement — even 10-20 hours/week — can dramatically extend portfolio longevity.

Work Level Annual Income Impact on Portfolio
Minimal (consulting, gigs) $5,000 – $15,000 Reduces annual withdrawal by 12-37%
Part-time (20 hrs/week) $18,000 – $35,000 Often fully covers discretionary spending
Encore career (full role) $40,000 – $80,000+ May eliminate portfolio withdrawal entirely

Important: If collecting Social Security before full retirement age (67), earnings above $22,320/year (2026) temporarily reduce benefits by $1 for every $2 earned. Benefits are restored at FRA.

Reverse Mortgage

Allows homeowners 62+ to convert home equity into income without selling. Most common: Home Equity Conversion Mortgage (HECM).

Payout Option How It Works
Monthly payment Fixed monthly income for as long as you live in the home
Line of credit Draw when needed; unused credit line grows
Lump sum One-time payment (less common; fixed interest rate)

Key facts: No repayment while you live in the home. Loan becomes due when you sell, move, or die. Heirs can repay the loan and keep the home or sell the home and keep any equity above loan balance.

Best for: House-rich, cash-poor retirees who plan to stay in their home long-term.

Building Your Income Stack

A resilient income plan layers sources to cover different needs:

Priority Income Type Purpose
1 Social Security (optimized claiming age) Core guaranteed income
2 Pension (if available) Additional guaranteed floor
3 SPIA annuity (if gap remains) Close any floor gap
4 Taxable account / dividends Low-tax discretionary income
5 Traditional IRA / 401(k) Fill needed income, manage brackets
6 Roth IRA High-income years; late retirement
7 Part-time work (if desired) Supplement early retirement years
8 Rental income (if applicable) Inflation-adjusted supplement
