Understanding Pension Payouts

Defined-benefit pension basics

Expert Tips

• Annuity vs. Lump Sum: The annuity guarantees income for life; the lump sum gives you control and flexibility but shifts investment and longevity risk to you. Consider your health, other income, and investment comfort.
• Understand Survivor Options: A single-life annuity pays the most but stops at your death. Joint-and-survivor elections reduce your payment but continue paying your beneficiary after you pass.

The Formula — Accrual-based calculation

Core Formula

• Accrual Formula: Annual Pension = Years of Service × Accrual Rate × Final Average Salary - the standard defined-benefit calculation used by most pension plans.
• Payout Elections: Choosing single-life vs. joint-and-survivor changes your monthly amount - joint options trade a lower payment for continued income to your beneficiary.

Frequently Asked Questions

Should I take the lump sum or the monthly annuity?

It depends on your health, other income sources, investment comfort, and whether you need guaranteed income. The annuity guarantees income for life; the lump sum gives you control and flexibility but shifts investment and longevity risk to you.

What is a joint-and-survivor annuity?

It reduces your monthly pension in exchange for continuing a percentage (typically 50%, 75%, or 100%) of that payment to your spouse or beneficiary after you die. A single-life annuity pays more but stops entirely at your death.

What is "final average salary"?

Most pension plans use the average of your highest-earning consecutive years (commonly your final 3-5 years) rather than a single year, to smooth out any one-time bonuses or salary drops.

Does my accrual rate ever change?

Some plans use tiered accrual rates (e.g., a higher rate after 20 years of service) or have changed rates for newer employees. Check your specific plan documents for your exact accrual formula.

Is this the same as a 401(k) or Social Security?

No - a defined-benefit pension is a separate, employer-funded guaranteed benefit based on a formula, unlike a 401(k) (a defined-contribution account you fund and invest yourself) or Social Security (a separate government program). Many people have all three.
