A pension is one of the most valuable — and most misunderstood — retirement assets you can have. Whether you have a traditional defined benefit plan (where your employer promises a specific monthly payment based on years of service and salary) or a defined contribution plan (where you've built up a balance that needs to convert to income), this calculator shows exactly what you can expect to receive each month in retirement. For defined benefit pensions, the standard formula is: years of service × final average salary × benefit multiplier. A teacher with 30 years of service, a $75,000 final salary, and a 2% multiplier receives $45,000/year, or $3,750/month — for life. Variations include early retirement penalties (typically 5% per year before normal retirement age), survivor benefit elections (which reduce your benefit to provide income to a spouse after your death), and COLA adjustments (cost of living increases, which many public pensions no longer offer). For defined contribution plans (a balance you've accumulated), the calculator converts your lump sum to an estimated monthly income using standard annuity payout rates, and compares that to what a systematic withdrawal strategy would provide. Understanding the gap between your pension income and your actual expenses is the critical output — it determines how much additional savings, Social Security, or part-time income you need to bridge.

Maria is a public school teacher with 28 years of service, a final average salary of $72,000, and a 2.2% multiplier. Her pension: 28 × $72,000 × 2.2% = $44,352/year = $3,696/month. She's considering a survivor benefit (50% to her spouse), which reduces her payment by 8% to $3,400/month. Her monthly expenses in retirement will be $5,200. The calculator shows a $1,800/month gap — covered by $1,400 in Social Security and $400/month from her investment portfolio.
What is the typical pension benefit multiplier?
Benefit multipliers vary significantly by employer and plan. Public school teachers typically have multipliers of 1.5–2.5%. Police and fire plans often range from 2.5–3.5% due to earlier retirement ages. Private sector defined benefit plans (increasingly rare) typically range from 1.0–1.75%. Military pensions pay 2.5% per year of service for retirements under the legacy High-3 system.
Should I take the pension lump sum or monthly annuity?
The break-even analysis is critical: divide the lump sum by the monthly annuity payment to get the 'payback period' in months. If you'd need to live 22 years to break even and you're 62 and in good health, the annuity likely wins. If you're in poor health, have other guaranteed income, or have dependents who won't benefit from the annuity's death protection, the lump sum may be better. The annuity eliminates longevity risk; the lump sum gives you control and inheritance potential.
What is a pension survivor benefit and how much does it cost?
A survivor benefit guarantees your spouse (or other beneficiary) continues receiving pension income after your death. Common options: 50% survivor (you take a 5–10% reduction in your benefit; spouse receives 50% when you die), 75% survivor (larger reduction, higher spouse benefit), and 100% survivor (largest reduction, spouse receives your full benefit). The cost varies by age difference between spouses and the plan's actuarial assumptions.
What happens to my pension if I leave my job before retirement?
Vesting schedules determine what you keep. Cliff vesting means you vest 100% after a set period (often 5 years) and nothing before. Graded vesting provides partial vesting over time (e.g., 20% per year from years 2–6). Once vested, you typically can: leave the benefit in the plan and collect at retirement age, roll a defined contribution balance to an IRA, or in some cases take a lump sum. Early departure usually means losing years-of-service credit that would have increased your benefit.
