In a defined benefit pension, the transfer value is the lump sum the plan’s actuary calculates as today’s equivalent of the monthly retirement income you have already earned. It is the present value of a future stream of payments, discounted back to now using interest rates and mortality assumptions set by the IRS. Take that lump sum and you get immediate control of your retirement capital; you also permanently trade away a guaranteed monthly check for a pile of money you have to manage yourself. Because the math leans so heavily on interest rates, the same pension can produce very different transfer values from one month to the next.
What a Transfer Value Actually Is
If you have a 401(k), the concept does not really apply. Your “transfer value” there is just your account balance, because the money already sits in a discrete account with your name on it. Defined benefit plans are different. The employer promises a specific monthly income at retirement, usually tied to your salary history and years of service, and the employer carries the investment risk of funding that promise.1U.S. Department of Labor. FAQs about Retirement Plans and ERISA
When you leave that employer before retirement and want to take the pension with you, an actuary has to convert decades of future monthly payments into a single dollar figure that can be rolled into an IRA or another employer’s plan. That figure answers one question: how much money would the plan need to set aside today to cover every payment it promised you? The answer depends on how long you are expected to live, when you are assumed to start drawing benefits, and what rate of return the money could earn in the meantime. Small changes in any of those assumptions move the lump sum by tens of thousands of dollars.
What Drives the Number
Four inputs do almost all the work.
Your Accrued Benefit
The starting point is the annual pension income you have earned through your service date. Most DB plans use a formula tied to final average salary and credited years of service. A plan formula of 1.5% of final average pay per year of service, applied to 20 years of work at an $80,000 final average salary, produces an accrued benefit of $24,000 per year. That is the annual figure the actuary converts.
Assumed Retirement Age
The calculation has to assume when payments would begin. If the plan uses a normal retirement age of 65 and you ask for the lump sum at 50, the actuary discounts 15 years before the payment stream even starts. A later assumed retirement age generally produces a lower lump sum, because the plan has more time to invest before it owes you anything.
Mortality Assumptions
The IRS requires plans to use a specific unisex static mortality table that blends male and female rates when they calculate lump-sum distributions.2Internal Revenue Service. Updated Static Mortality Tables for Defined Benefit Pension Plans A longer projected lifespan means more years of payments to fund, which pushes the lump sum up.
The Discount Rate
This is the variable that matters most. The discount rate is the assumed rate of return on money set aside today. A higher rate means the plan expects investments to grow faster, so it needs less money now to cover your future payments. A lower rate means slower expected growth and a larger lump sum. The relationship is inverse and powerful. Even a half-percentage-point drop in the discount rate can increase a lump sum by 5% to 10%, depending on your age and benefit size.
Why Timing Matters: IRS Segment Rates
Plans do not pick their own discount rates. Federal law requires single-employer DB plans to use three “segment rates” published monthly by the IRS under Internal Revenue Code Section 417(e)(3).3eCFR. 26 CFR 1.417(e)-1 – Restrictions and Valuations of Distributions From Plans in Which Some Participants Are Not Fully Vested The rates come from yields on high-quality corporate bonds and change every month:
- The first segment rate applies to payments expected during the first five years after your annuity starting date.
- The second segment rate applies to payments expected during the following 15 years.
- The third segment rate applies to all payments beyond 20 years.
As of early 2026, the segment rates are roughly 4.0%, 5.2%, and 6.1%.4Internal Revenue Service. Minimum Present Value Segment Rates These set the floor for your lump sum. The plan must pay you at least the present value produced by these rates and the IRS mortality table. Some plans use their own assumptions that produce a more generous result, but they cannot pay less than the IRS minimum.
When rates rise, lump sums fall. When rates drop, lump sums climb. If you are considering a lump-sum offer and rates are trending down, waiting a few months might put more money on the table, but rates are unpredictable and you cannot time the bond market. The number the plan quotes reflects a snapshot of rates at a specific moment, so check the current segment rates on the IRS site before you request a formal quote.
When Plan Funding Can Restrict Your Payout
Even if you are entitled to a lump sum, an underfunded plan may be legally prohibited from paying it. Internal Revenue Code Section 436 ties a plan’s ability to make lump-sum distributions to its adjusted funding target attainment percentage (AFTAP), a measure of how well-funded the plan is relative to its obligations.5Office of the Law Revision Counsel. 26 U.S. Code 436 – Funding-Based Limits on Benefits and Benefit Accruals Under Single-Employer Plans
- AFTAP below 60%: the plan cannot pay any lump sums. You are stuck with the annuity form of benefit until funding improves.
- AFTAP between 60% and 80%: the plan can pay a partial lump sum, capped at the lesser of 50% of the unrestricted amount or the present value of the PBGC maximum guarantee for your age.
- AFTAP at 80% or above: lump sums are generally unrestricted, unless the employer is in bankruptcy.
If the employer is in bankruptcy, lump sums are blocked entirely unless the plan is at least 100% funded.5Office of the Law Revision Counsel. 26 U.S. Code 436 – Funding-Based Limits on Benefits and Benefit Accruals Under Single-Employer Plans These restrictions protect remaining participants; if a severely underfunded plan cashed out everyone who asked, the last people in line would have nothing left. Your plan’s AFTAP is disclosed in the annual funding notice the plan is required to send you.
Requesting the Payout and Getting Spousal Consent
You start by contacting your plan administrator or former employer’s HR department, usually in writing. Under IRC Section 417(a), you must receive written notice of your right to waive the annuity form of benefit at least 30 days before your annuity starting date, and you have up to 180 days to make your election. Plan documents can shorten the window, but 180 days is the statutory maximum. Miss it and the plan will re-value the benefit at whatever segment rates are then in effect.
For a lump-sum window (a limited-time offer to cash out your pension), ERISA now requires the plan to send you detailed disclosure at least 90 days before the election period opens, including the lump-sum amount, the interest rates and mortality assumptions used to calculate it, and a comparison to the annuity options.6Office of the Law Revision Counsel. 29 U.S. Code 1032 – Notice and Disclosure Requirements
If you are married and your plan is subject to the qualified joint and survivor annuity rules, your spouse has a legally protected right to survivor benefits. Choosing a lump sum waives that protection, and the plan cannot process the payout without your spouse’s written consent, witnessed by a plan representative or a notary. There is one exception: if the total lump-sum value is $5,000 or less, the plan can pay it without your election or your spouse’s consent.7Internal Revenue Service. Fixing Common Plan Mistakes – Failure to Obtain Spousal Consent Above that, the consent requirement is absolute, and administrators are meticulous about the paperwork.
In practice, expect several weeks to a few months from your initial request to funds landing in a rollover account, while the plan calculates the benefit, confirms the payment schedule, and liquidates the necessary investments.8Internal Revenue Service. When Can a Retirement Plan Distribute Benefits?
Taxes and How to Receive the Money Without Wrecking It
A direct trustee-to-trustee rollover into a traditional IRA or another qualified plan triggers no immediate tax. The pension money moves straight from the plan’s trustee to the receiving institution without you ever touching it, and it stays tax-deferred until you withdraw in retirement. Getting this wrong is expensive.
If the plan cuts the check to you instead of to the receiving institution, it must withhold 20% for federal income taxes even if you intend to complete the rollover yourself.9Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans You then have 60 days to deposit the full original amount into a qualified account. To roll over the entire distribution and avoid tax on any portion, you have to replace the withheld 20% from your own pocket, then recover it when you file your return.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions On a six-figure lump sum, that is real cash to come up with on short notice.
Miss the 60-day window entirely and the full amount becomes taxable as ordinary income in the year you received it. If you are under age 59½, you also owe an additional 10% early withdrawal penalty under IRC Section 72(t).11Internal Revenue Service. Exceptions to Tax on Early Distributions On a $300,000 lump sum for someone in the 24% bracket, that mistake could cost more than $100,000 in combined taxes and penalties. Either way, the plan reports the distribution on IRS Form 1099-R.12Internal Revenue Service.

Should You Take the Transfer Value at All
Taking the lump sum means accepting the investment risk and longevity risk the pension plan was previously carrying for you. The annuity pays the same amount every month whether markets crash or you live to 105. A lump sum could grow faster than the annuity’s implicit rate of return, or it could get chewed up by a bad sequence of market returns early in retirement.
A rough starting point is to divide your annual pension by the lump-sum offer. If the plan offers $300,000 and your annual pension would be $18,000, you would need a consistent 6% annual return on the lump sum just to match the annuity income without touching the principal. Annuity payments are designed to draw down principal over your lifetime, so the real comparison is more nuanced than a simple yield calculation. The longer you live past your actuarial life expectancy, the better the annuity looks.
Factors that tilt toward the lump sum: poor health or a family history of shorter lifespans, a large existing portfolio that can absorb volatility, a desire to leave a larger inheritance, and confidence in your ability to manage the money or hire someone competent to do it. Factors that tilt toward keeping the annuity: a long family lifespan, limited other retirement income, discomfort with investment decisions, and a spouse who will rely on the survivor benefit. Most private-sector DB pensions do not include cost-of-living adjustments, so the purchasing power of a fixed monthly check erodes with inflation over a long retirement.
One more thing you give up by cashing out: if your former employer’s plan is later terminated without enough assets to pay all promised benefits, the Pension Benefit Guaranty Corporation covers pensions up to a legal maximum set each year by Congress.13Pension Benefit Guaranty Corporation. Guaranteed Benefits That backstop disappears the moment the money moves into your IRA. The PBGC maximum guarantee varies by the age at which benefits begin, and most participants in trusteed plans receive benefits below the cap.14Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables For a well-funded plan at a healthy company, that trade-off may not weigh much. For an underfunded plan at a struggling employer, the guarantee may be the most valuable feature of the pension, and worth thinking hard about before walking away from it.
