About Pension Payout Calculator (Lump Sum vs Annuity)

The Pension Payout Calculator compares taking a defined-benefit monthly lifetime pension annuity vs. accepting a lump-sum cash buyout to roll into an IRA.

Formula & Mathematical Calculation

Present Value of Lifetime Pension = Monthly Pension × [ ( 1 - ( 1 + r )^-n ) / r ]

Lump Sum Advantage = Lump Sum Offer - Present Value of Pension Stream

Calculation Example

$2,500/Month Pension for 25 Years vs. $380,000 Lump Sum Offer @ 6% Discount Rate: PV of Monthly Pension = $388,053. Taking the monthly check provides +$8,053 more value plus guaranteed market immunity.

Frequently Asked Questions

Monthly payments provide guaranteed lifetime income without market risk. A lump sum gives you investment control, inflation upside, and the ability to leave remaining funds to heirs.

It converts the stream of monthly payments into a single present value using the present-value formula for an ordinary annuity, then subtracts that value from the lump sum offer. The monthly rate is your discount rate divided by 12, and the number of periods is the payout years times 12.

It is the annual return you assume you could earn if you took the lump sum and invested it instead. A higher discount rate lowers the present value of the future monthly payments, making the lump sum look relatively more attractive, while a lower rate raises the payments' present value.

The tool computes the advantage as the lump sum minus the present value of the payments. When that number is positive, the lump sum is worth that much more than the payment stream; when it is negative, the monthly payments are worth the absolute value of that figure more than the lump sum.

It multiplies your monthly amount by the number of months, which is the payout years times 12. This undiscounted total is usually larger than the present value, because it ignores the time value of money that the discount rate accounts for.
