Pension Buyout Calculator
Compare a pension buyout lump sum with the present value of monthly pension payments, break-even age and implied hurdle return.
Compare a pension lump-sum buyout offer with the present value and projected cash flow of monthly pension payments using your own age, planning horizon, COLA and discount-rate assumptions.
Pension buyout comparison
A pension buyout calculator helps you compare a one-time lump-sum offer with the future monthly pension payments you would give up. This calculator focuses on the comparison you can control: your pension amount, payment start age, planning horizon, COLA assumption and comparison rate.
It reports the estimated present value of the modeled pension stream, the total nominal pension payments through your selected planning age, a raw-dollar break-even age, and the annual hurdle rate that makes the modeled pension stream approximately equal to the buyout offer.
How a Pension Buyout Is Valued
A defined-benefit pension normally promises a stream of monthly payments. A lump-sum buyout converts that future stream into one amount today. PBGC explains that official pension lump-sum calculations must account for actuarial assumptions such as interest rates and mortality because nobody knows exactly how long an individual participant will live.
For many private U.S. plans, minimum present-value rules under Internal Revenue Code section 417(e) can involve IRS-published segment rates and applicable mortality tables. Your plan may also specify a lookback month, stability period, early-retirement factors and optional payment forms. Those details are why this tool does not claim to reproduce your plan administrator’s official lump-sum value.
Present Value Used by This Calculator
The calculator discounts each modeled monthly payment back to today. If you enter a COLA, it applies that increase once per pension year. Payments can also be deferred if your pension starts at a later age.
Conceptually:
Present value = sum of each future pension payment ÷ (1 + annual discount rate)time in years
A higher comparison rate lowers the present value of the future pension stream. A longer payment horizon or a larger COLA generally raises it.
What Is the Pension Hurdle Rate?
The hurdle rate is the annual discount/return rate at which the present value of the modeled monthly pension equals the lump-sum offer. It is useful because it puts the two choices on one mathematical scale. It is not a promised investment return or a recommendation to accept either option.
Break-Even Age
The raw-dollar break-even age is the age at which cumulative pension checks first equal the buyout offer, without discounting those payments. If a COLA is entered, the calculator includes it. This is different from present value because a dollar received decades from now is not treated as equal to a dollar today in the discounted analysis.
Important Factors This Calculator Does Not Decide for You
Taxes, rollover treatment, investment fees, plan funding, PBGC guarantee limits, personal health, survivor needs, estate goals, inflation risk and investment volatility can materially change the real-world decision. A joint-and-survivor pension also has different economics from a single-life pension. Use the exact pension option shown in your plan documents and review an irrevocable election with an appropriately qualified financial or tax professional.
Frequently Asked Questions
Is a pension buyout the same as the present value of my pension?
It is intended to represent an actuarial present value under the plan’s governing rules, but your personal planning value can differ because you may use different longevity, return, inflation or survivor assumptions.
Why does a higher interest rate usually reduce a pension lump sum?
Future payments are discounted more heavily when the valuation rate is higher, so their value today is lower. IRS publishes minimum present-value segment rates used for applicable section 417(e) calculations.
Does this calculator include mortality tables?
No. It uses an explicit planning age so you can see the effect of your chosen horizon. Official plan calculations can use prescribed mortality tables and should be obtained from the plan administrator.
Does this calculator include taxes?
No. Pension distributions and rollovers can have important tax consequences, and tax treatment depends on how the distribution is made and your circumstances.
