A defined benefit pension provides guaranteed monthly income in retirement based on a formula — typically years of service, salary history, and a benefit multiplier. This calculator estimates your monthly pension benefit at retirement, the lump-sum equivalent value, and compares the pension against what you might accumulate in a 401(k) with equivalent contributions over the same period.
Most defined benefit pensions use this formula:
Annual Pension = Years of Service × Benefit Multiplier × Final Average Salary
The benefit multiplier is typically 1.0%–2.5% per year of service. A teacher with 30 years of service, a 2% multiplier, and $70,000 final average salary receives: 30 × 2% × $70,000 = $42,000 per year ($3,500/month). Public sector pensions often use the highest 3–5 years of salary, which significantly increases the benefit for late-career promotions.
Vesting is when your right to pension benefits becomes non-forfeitable. Private sector pensions must follow ERISA: either 100% vesting after 5 years (cliff) or graded vesting of 20% per year starting in year 3 (fully vested after 7 years). Public sector pensions often require 5–10 years. Leaving before vesting means losing some or all of the employer-funded benefit.
Most pensions offer multiple options: single life annuity (highest monthly payment, stops at death), joint and 50% survivor (reduced payment continuing at 50% to surviving spouse), or joint and 100% survivor (further reduced, full payment continues to spouse). The calculator quantifies the trade-off based on both spouses' ages.
Many plans offer a lump-sum buyout instead of monthly payments. The lump sum is the present value of future annuity payments calculated using IRS segment rates. In low-rate environments, lump sums are more generous; in high-rate environments, they're smaller. If the implied annuity return exceeds what you could safely earn on the lump sum, the annuity is typically better.
A pension provides guaranteed lifetime income regardless of market performance — you cannot outlive it. A 401(k) is subject to investment risk but offers flexibility, portability, and potential for greater wealth with strong markets. Most financial planners recommend maximizing both if available. The pension's value depends heavily on how long you live and the financial strength of the sponsor.
Yes — pension payments from employer-funded defined benefit plans are generally taxable as ordinary income. If you contributed after-tax dollars, a portion of each payment is tax-free (return of your basis). Many states exempt pension income from state income tax, particularly for government or public safety pensions — check your state's specific rules.
If vested, you can typically: leave the benefit in the plan and collect it at normal retirement age (deferred vested benefit), take a lump-sum distribution (subject to taxes and penalties if under 59½), or roll a lump sum into an IRA to avoid immediate taxes. The deferred vested benefit typically does not adjust for inflation, so a benefit earned 20 years before retirement may be significantly diminished in real terms.
Private sector pensions are insured by the Pension Benefit Guaranty Corporation (PBGC) up to $7,362/month for a single life annuity at age 65 in 2024 — providing partial protection if your employer goes bankrupt. Public sector pensions are not covered by the PBGC; their security depends entirely on the financial health of the state or municipality.
Model total retirement income with the Social Security Calculator alongside your pension. The Retirement Withdrawal Calculator shows how long savings need to last to fill any income gap. Compare to 401(k) accumulation with the 401(k) Calculator.
