How Much Income Will Your Pension Provide?

Understanding Your Pension Formula

For defined benefit (DB) pensions, your monthly benefit is determined by a formula your employer established — not by investment returns or how much you contributed. The standard formula is: Years of Service × Final Average Salary × Benefit Multiplier. A teacher with 30 years of service at a $70,000 final salary and a 2% multiplier earns $42,000/year, or $3,500/month, for life.

The three levers in the formula matter enormously. One additional year of service adds the full multiplier percentage to your benefit. Working one more year from 29 to 30 years at $70,000 with a 2% multiplier adds $1,400/year — permanently. This is why the decision of when to retire is so consequential for DB pension holders.

Final average salary is typically calculated over your last 3–5 years of employment. Maximizing your salary in those final years — through promotions, overtime, or unused leave payouts where allowed — can meaningfully increase your lifetime benefit.

The multiplier varies significantly by plan type. Public safety workers (police, fire, corrections) often have 2.5–3% multipliers with earlier retirement eligibility. Teachers typically range 1.5–2.5%. Federal FERS civilian employees use 1% (1.1% at 62+ with 20+ years). Private sector DB plans, increasingly rare, often use 1.0–1.5%.

How to Evaluate Your Pension Decision

1
Get your official pension estimate from your employer
Contact your HR department or pension administrator for a formal pension estimate at your expected retirement date. This will show your exact projected benefit under your plan's formula, any early retirement reduction factors, and the available payout options with their specific benefit amounts. Don't rely on informal estimates — get it in writing.
2
Calculate your retirement income gap
Add your expected pension + Social Security + any other guaranteed income. Compare to your projected monthly expenses in retirement (don't forget health insurance, which may cost $600–2,000/month before Medicare eligibility at 65). The gap between guaranteed income and expenses determines how much investment savings you need to draw from — and at what rate.
3
Evaluate the survivor benefit decision carefully
If you're married, the survivor benefit decision is one of the most consequential you'll make. Compare: your monthly reduction vs. the financial impact on your spouse if you predecease them. If your spouse has their own pension and Social Security, the survivor benefit may be less critical. If your spouse has little independent income, maximizing their protection may be worth the reduction.
4
Consider the lump sum vs. annuity decision if offered
Some plans offer a lump sum buyout option. To evaluate: if the lump sum is $X and the monthly annuity is $Y, divide X ÷ (Y × 12) to get the breakeven years. If you'd need to live 25+ years to break even, the annuity may win. If the lump sum break-even is under 15 years and you're in good health, invest the lump sum. Also consider: annuities eliminate longevity risk; lump sums allow inheritance.
5
Plan for what the pension doesn't cover
Most pensions don't include cost-of-living adjustments (COLA) — your benefit is fixed in nominal dollars. At 3% annual inflation, your $3,500/month pension loses 26% of its purchasing power in 10 years. Plan for this erosion by building investment savings that can grow and offset inflation, or by setting a withdrawal rate from savings that accounts for your pension's fixed nature.

Payout Options: What Each Provides

Life-Only Annuity

✓Highest monthly payment — maximize income while both alive
✓Payments stop when you die — spouse receives nothing
✓Best when: spouse has own substantial income or is in poor health
✓Best when: you're single or have no financial dependents
✓Risk: if you die early, you may have 'left money on the table'

Joint & Survivor Annuity

✗Reduced monthly payment during your lifetime
✗Spouse continues receiving 50%, 75%, or 100% when you die
✗Best when: spouse has limited independent income
✗Best when: health history suggests you may predecease spouse
✗Cost: typically 5–15% reduction depending on option and age gap

Pension Planning Questions

Can I collect my pension and still work?

It depends on your plan and employer. Many public pension plans have earnings limits — if you return to work for the same employer (or in the same system), your pension may be suspended or reduced. Private sector pensions are generally not affected by post-retirement employment. Some plans have 'bona fide separation' requirements meaning you must remain separated from the employer for a defined period before returning.

Is my pension income taxable?

Generally yes, if you contributed pre-tax dollars (most public and private pensions). The full distribution is ordinary income. If you made after-tax contributions, only the earnings portion is taxable — your employer's pension administrator should provide an exclusion ratio. State taxation varies significantly: some states exempt pension income (NY, PA, Mississippi); others tax it fully. Check your state's rules.

What happens to my pension if my employer goes bankrupt?

Private sector defined benefit pensions are insured by the Pension Benefit Guaranty Corporation (PBGC), a federal agency, up to maximum limits ($81,000/year for plans ending in 2024, for a 65-year-old retiree). If your pension exceeds PBGC limits, you may receive less. Public sector pensions (government employees) are not insured by PBGC — they depend on the financial health of the government entity and state law protections.
