Formula Used
The calculator estimates the present value of future pension payments. It treats the pension as a growing monthly annuity.
Main pension value:
PV = P × [1 - ((1 + g) / (1 + r)) ^ n] / (r - g)
Here, P is monthly pension payment. r is monthly discount rate. g is monthly COLA growth. n is total monthly payments.
Survivor value:
Survivor PV = Survivor Payment PV / (1 + r) ^ main months
Adjusted pension value:
Adjusted PV = Deferred PV × Mortality Factor × (1 - Plan Risk Haircut)
Net buyout value:
Net Buyout = Gross Offer - Taxes - Penalties - Fees
The tool also compares after-tax pension value against net lump sum proceeds.

Pension Buyout Planning Guide
What a Pension Buyout Means
A pension buyout is a lump sum offer. It replaces future monthly pension payments. The offer may look large at first. Yet the correct comparison is not simple. You must compare one payment today against many payments over time.
Why Present Value Matters
Present value converts future payments into today’s dollars. A dollar received today can be invested. A dollar received later has lower value. The discount rate controls this adjustment. A higher discount rate lowers the value of future pension income. A lower rate raises it.
Taxes Can Change the Result
Taxes are very important. A rollover may delay tax. A direct payment may create immediate tax. It may also trigger penalties. Monthly pension payments may be taxed differently. This calculator lets you compare both sides after tax.
Survivor Benefits Add Value
Many pensions include survivor protection. This can continue income for a spouse. A lump sum may remove that guarantee. You can estimate survivor payment years and benefit percent. This helps show the hidden value of protection.
Risk and Flexibility
A monthly pension gives steady income. It may reduce investment stress. A lump sum gives control and flexibility. It may help with estate planning. It also creates investment risk. Poor returns can reduce future income.
Health and Life Expectancy
Life expectancy is a major factor. A longer life makes monthly payments more valuable. Shorter expected longevity can make a buyout more attractive. The mortality factor allows a simple health adjustment. Use conservative estimates when unsure.
Review Before Deciding
Use several scenarios. Try high and low discount rates. Test different tax rates. Compare results before accepting any offer. A pension choice can be permanent. A professional review may be useful for large balances.
FAQs
What is a pension plan buyout?
A pension buyout is a lump sum payment offered instead of future monthly pension income. The plan transfers payment responsibility to you after acceptance.
Is a higher lump sum always better?
No. A lump sum must be compared with the present value of monthly payments, survivor benefits, taxes, fees, and investment risk.
What discount rate should I use?
Use a rate that reflects your expected safe return or required investment return. Test several rates to see how sensitive the result is.
Why does COLA matter?
COLA increases future payments. Even small annual increases can raise pension value over long periods, especially when retirement lasts many years.
How are taxes handled?
The calculator allows rollover or direct payment treatment. Direct payment applies entered tax and penalty rates. Pension income tax is estimated separately.
What does mortality factor mean?
It adjusts pension value for health or life expectancy assumptions. A value below 100 reduces pension value. A value above 100 increases it.
Should I include survivor benefits?
Yes, if your pension protects a spouse or beneficiary. Survivor benefits can add meaningful value that a lump sum may not replace automatically.
Can this calculator make the final decision?
No. It supports analysis only. Final decisions should consider taxes, health, income needs, estate goals, risk tolerance, and professional guidance.
