A pension annuity is the default form of benefit payment from a defined benefit pension plan. Instead of receiving a lump sum at retirement, you receive a fixed monthly income for the rest of your life (and potentially your spouse’s life). The monthly amount is determined by a formula tied to your service and earnings — not by market performance.
What a Pension Annuity Is (and Is Not)
A pension annuity is not an annuity you purchase. It is the income stream your employer’s defined benefit pension plan pays you based on your years of service and compensation. You earned it as a workplace benefit.
This is distinct from:
- A retail annuity you buy from an insurance company with your own savings
- A structured settlement annuity from a personal injury lawsuit
- An individual retirement annuity (IRA structured as an annuity contract)
How the Monthly Benefit Is Calculated
Standard defined benefit pension formula: Monthly benefit = (Years of service x Final average salary x Accrual rate) / 12
Example:
- 30 years of service
- Final 5-year average salary: $72,000
- Accrual rate: 1.5%/year
Monthly benefit = (30 x $72,000 x 0.015) / 12 = $32,400 / 12 = $2,700/month
Accrual rates by plan type:
| Plan type | Typical accrual rate |
|---|---|
| Private sector (corporate) | 1.0%–1.5%/year |
| State and local government | 1.5%–2.5%/year |
| Federal FERS | 1.0%/year (1.1% if retiring at 62+ with 20+ years) |
| Military retirement | 2.5%/year (20-year minimum) |
Survivor Annuity Options
At retirement, most pension plans require you to choose a payment form. The choice is typically irrevocable. Key options:
Single life annuity: Highest monthly payment; stops at your death. No income for spouse.
Joint and survivor annuity (50%): Reduced monthly payment for you; spouse receives 50% of that reduced amount after your death. Federal law (ERISA) requires married private-sector employees to elect at least a 50% joint and survivor annuity unless the spouse consents in writing to waive it.
Joint and survivor annuity (100%): Further reduced payment for you; spouse receives 100% of that amount for life. Best if your spouse has little independent income.
Period certain: Payments guaranteed for a set period (e.g., 10 or 20 years). If you die before the period ends, a beneficiary receives the remaining payments.
Does Your Pension Adjust for Inflation?
Private sector pensions: Most do not include automatic cost-of-living adjustments (COLA). A $2,700/month pension in 2026 pays the same nominal amount in 2046 — but inflation at 3%/year means real purchasing power falls to approximately $1,635/month in 20 years.
Government pensions: Many include annual COLA tied to CPI (Social Security-style), capped COLA (e.g., 2%/year max), or ad hoc adjustments approved by the plan sponsor.
PBGC Protection If Your Employer’s Pension Fails
The Pension Benefit Guaranty Corporation (PBGC) insures private-sector defined benefit pensions. If your employer goes bankrupt or terminates an underfunded plan, PBGC takes over and pays benefits up to the annual maximum guarantee.
2026 PBGC maximum guaranteed benefit:
| Age at retirement | Maximum monthly guarantee (single life) |
|---|---|
| 65 | $7,362.50/month |
| 62 | ~$5,889/month |
| 60 | ~$4,786/month |
| 55 | ~$3,313/month |
Benefits above these limits may be partially reduced in a PBGC takeover.
Government pensions (federal, state, local) are NOT covered by PBGC. They are backed by the government entity sponsoring the plan.
Annuity vs Lump Sum: The Decision Framework
| Choose annuity when: | Choose lump sum when: |
|---|---|
| You are in good health and expect to live 20+ years | You are in poor health with shorter life expectancy |
| You lack other guaranteed income | You have a pension + large Social Security already |
| Your spouse needs survivor income | Your spouse has independent income |
| You want income certainty without managing investments | You want flexibility and investment control |
| You are not confident managing a large lump sum | You have financial sophistication and a plan |
The break-even point — how long you must live for the annuity to exceed the lump sum — is typically 12–20 years from retirement, depending on the plan’s lump sum calculation method.
