Pension

How pensions work

A typical defined-benefit pension:

1. Employee works for company for some period.
2. Employer (and sometimes employee) contributes to a pension fund.
3. Fund invests the contributions to grow over time.
4. At retirement, employee receives monthly payments based on a formula.
5. Payments continue for life (sometimes with survivor benefits for spouse).

The defining feature: predictable income for life, regardless of investment performance.

Pension formulas

A common formula:

Annual Pension = Years of Service × Final Salary × Multiplier

A 30-year employee with $80,000 final salary and 1.5% multiplier receives 30 × 80,000 × 1.5% = $36,000/year for life.

Variations:

• Average final salary vs. single highest year.
• Different multipliers by service tier.
• Cost-of-living adjustments (sometimes).

Defined benefit vs. defined contribution

Two different retirement structures:

• Defined benefit (traditional pension) — employer guarantees specific retirement income. Employer bears investment risk.
• Defined contribution (401(k)) — employer contributes specific amount; investment outcomes determine retirement income. Employee bears investment risk.

The shift from defined-benefit to defined-contribution has been one of the major retirement-system changes since the 1980s.

Why pensions have declined

Several factors:

• Cost predictability — defined benefit creates open-ended employer liability.
• Investment risk — employers bear investment outcomes.
• Mobility mismatch — modern workers change jobs more often; pensions reward longer tenure.
• Regulatory burden — pension administration is complex.

In response, most US private-sector employers have moved to 401(k)-based defined-contribution plans.

Where pensions still exist

A few sectors retain pensions:

• Public-sector employment — federal, state, local government workers often still have pensions.
• Union jobs — collectively bargained pensions in specific industries.
• Some legacy private companies — typically with frozen plans for existing employees.
• Some industries with long tenure — utilities, certain large manufacturers.

For most private-sector workers under 50, pensions are unfamiliar.

Pension underfunding

A persistent issue, especially in public sector:

• Many state and local pension funds are significantly underfunded.
• Future obligations exceed projected fund growth at conservative discount rates.
• Aggressive return assumptions mask the gap in some cases.
• Some major examples — Illinois, New Jersey, Connecticut state pensions; Detroit's pension struggles during bankruptcy.

Underfunding creates pressure for reduced benefits, increased contributions, or eventual taxpayer subsidies.

Pension Benefit Guaranty Corporation (PBGC)

US federal backstop:

• Insures private-sector defined-benefit pensions.
• Maximum guaranteed benefit caps protection.
• Funded by premiums from covered plans.
• Itself underfunded in some segments.

Provides some protection but doesn't fully restore lost benefits in failed plans.

Pension vs. Social Security

Two retirement income sources:

• Social Security — government-provided defined-benefit-like income.
• Pension — employer-provided defined-benefit income.
• Both provide guaranteed income different from market-based retirement accounts.

For many workers, especially those without pensions, Social Security is the primary guaranteed-income component of retirement.

Pension lump-sum option

Many pensions offer a choice:

• Monthly payments for life — traditional pension structure.
• Lump-sum equivalent — single payment at retirement.

The tradeoff:

• Monthly payments — guaranteed income, longevity protection, no investment management.
• Lump sum — full control, can pass to heirs, requires investment management.

The math depends on life expectancy, interest rates, and investment skill. Most analysis favors keeping the monthly payment for typical retirees with normal life expectancy.

What individuals should know

For workers with pensions:

• Understand your formula — how benefits are calculated.
• Watch funding status — significantly underfunded plans face benefit risk.
• Consider tenure-based incentives — pension formulas often heavily reward long service.
• Evaluate lump-sum offers carefully — they're often less valuable than they appear.

For workers without pensions (most modern private-sector workers):

• 401(k)s are the modern equivalent.
• Combine multiple income sources — Social Security, retirement accounts, savings.
• Consider annuities for guaranteed income exposure.

Pensions represent an older retirement-income model that's largely been replaced. Where they still exist, they're often valuable benefits worth understanding fully. For most workers, the modern equivalent is building a 401(k)-based retirement portfolio with Social Security as the guaranteed-income backstop.
