To calculate a pension into your net worth, assign it a present-day dollar value using the method that fits your plan: the vested balance for a defined contribution account like a 401(k), the offered lump sum for a defined benefit plan that provides one, or the present value of your future annuity payments if the plan only pays lifetime monthly checks. Then reduce that figure for income taxes, inflation, unvested service, and anything already promised to a former spouse. The adjusted number is what belongs on your balance sheet next to your house and your brokerage account.
Gather the Right Documents First
You need two things before you can put a number on the pension. The first is your Summary Plan Description, which your plan is required to provide and which explains how benefits are calculated, when you can retire, and what payment options exist.1eCFR. 29 CFR 2520.102-3 – Contents of Summary Plan Description The second is your most recent annual benefit statement, which shows your accrued service and projected payout.
Three details on those documents change the math. Normal retirement age, which federal law generally defines as the earlier of the age your plan sets or 65 (or five years of participation, if later).2Office of the Law Revision Counsel. 29 U.S. Code 1002 – Definitions Whether the plan includes a cost-of-living adjustment. And which survivor option applies, since a joint-and-survivor annuity pays less per month than a single-life annuity. If any of these are missing from your statement, ask the plan administrator for a written benefit estimate that includes projected monthly amounts and available payment forms.
Defined Contribution Plans: Use the Vested Balance
A 401(k), 403(b), or similar plan established under Internal Revenue Code Section 401 is the easiest case, because the plan holds an actual cash balance in your name.3Office of the Law Revision Counsel. 26 U.S. Code 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans The current market value appears on your quarterly statement. The figure to use for net worth is your vested balance, meaning the portion you legally own and could take with you if you left tomorrow.
Your own salary deferrals are always fully vested. Employer contributions follow one of two federally required schedules: cliff vesting at 100 percent after three years, or graded vesting starting at 20 percent after two years and reaching 100 percent after six.4Office of the Law Revision Counsel. 29 U.S. Code 1053 – Minimum Vesting Standards Statements usually show a separate vested balance line. That is the number.
Defined Benefit Plans With a Lump Sum Option
Many traditional pensions let you take a lump sum instead of lifetime monthly checks.5Internal Revenue Service. Types of Retirement Plan Benefits If yours does, the lump sum figure is the most direct valuation you can use, because it is what the employer would actually pay today to settle the promise.6Pension Benefit Guaranty Corporation. Annuity or Lump Sum Plan actuaries have already discounted future payments back to present dollars using current interest rates and mortality tables, so the work is done. Look for it on your benefit statement or request it from the administrator. Some plans permit a partial lump sum with the rest paid as an annuity; make sure you know which figure you are reading.
Defined Benefit Plans With No Lump Sum: Calculate the Present Value
When the plan only pays a lifetime annuity, you have to convert that income stream into a single dollar amount yourself. The question the calculation answers is simple: how much would you need invested today to reproduce the income the pension will pay?
The Formula
Present Value = Annual Pension × [(1 − (1 + r)−n) / r]
Here r is your discount rate as a decimal and n is the number of years you expect to receive payments. The bracketed portion is the annuity factor, which accounts for both the time value of money and the finite payment period.
Picking a Discount Rate
The rate you choose has a large effect on the answer, so use something defensible. The IRS publishes a Section 7520 rate each month, set at 120 percent of the applicable federal midterm rate; for early 2026 it is 4.6 percent.7Internal Revenue Service. Section 7520 Interest Rates The current 10-year Treasury yield is another common benchmark. Either gives you a market-based starting point rather than a guess.
Estimating How Long You’ll Collect
For n, use a reasonable life expectancy. The IRS life expectancy tables in Publication 590-B are widely accepted for this purpose: the Uniform Lifetime Table assigns a factor of 24.6 at age 75 and 20.2 at age 80.8Internal Revenue Service. Publication 590-B (2025), Distributions from Individual Retirement Arrangements (IRAs) They were designed for required minimum distribution math, but they work as a baseline here too.
A Worked Example
Suppose your pension will pay $30,000 per year, you use a 5 percent discount rate, and you expect to collect for 20 years.
Annuity factor = (1 − (1.05)−20) / 0.05 = (1 − 0.3769) / 0.05 = 12.46
Present Value = $30,000 × 12.46 = $373,800
You would need roughly $373,800 invested today at a 5 percent return to reproduce that 20-year income stream. A tempting shortcut is to divide $30,000 by 0.05 to get $600,000, but that assumes the payments last forever and overstates the pension by a wide margin.
Reduce for Unvested Service
Defined benefit plans use one of two required vesting schedules: cliff vesting at 100 percent after five years, or graded vesting starting at 20 percent after three years and reaching 100 percent after seven.4Office of the Law Revision Counsel. 29 U.S. Code 1053 – Minimum Vesting Standards If you are not fully vested, scale the present value down. A $373,800 present value at 60 percent vesting becomes roughly $224,280.
Adjust for Taxes, Inflation, and Early Access
Income Tax
Pension distributions are taxed as ordinary income.9Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income To get a realistic net worth figure, reduce the gross value by your expected effective tax rate. If you made after-tax contributions, part of each payment may be tax-free; the plan administrator can tell you the taxable percentage.10Internal Revenue Service. Topic No. 411, Pensions – The General Rule and the Simplified Method
Inflation
If the plan has no COLA, inflation quietly erodes every future payment. One clean way to build that in is to subtract an assumed inflation rate from your discount rate, so a 5 percent nominal rate becomes a 2 to 3 percent real rate. The formula then produces a lower present value that reflects what those payments will actually buy. Plans with a COLA already price in inflation, so skip this step for those.
Early Withdrawal Penalty
If you plan to touch the money before age 59½, add the 10 percent additional tax on early distributions on top of the ordinary income tax.11Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Several exceptions apply, including separation from service after age 55, disability, and substantially equal periodic payments. SIMPLE IRA withdrawals within the first two years of participation carry a 25 percent penalty rather than 10 percent.
If Your Employer’s Plan Is Underfunded
A defined benefit number on paper assumes the plan will actually pay. If your employer’s plan fails, the Pension Benefit Guaranty Corporation pays benefits, but only up to a legal maximum. For 2026, the PBGC guarantees up to $7,789.77 per month (about $93,477 per year) for a single-life annuity starting at 65, and $7,010.79 per month for a joint-and-50-percent-survivor annuity at 65.12Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables Earlier retirement lowers the cap.
If your promised benefit exceeds the PBGC maximum and your employer’s financial condition is shaky, using the guaranteed amount rather than the promised amount produces a more honest net worth figure. Your plan’s annual funding notice tells you where it stands; funding at or above 80 percent is generally considered healthy.
If Part of the Pension Belongs to a Former Spouse
Pension benefits generally cannot be assigned to anyone but the participant, with one major exception: a Qualified Domestic Relations Order, which directs the plan administrator to pay a share to a former spouse.13Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits If a QDRO has already been entered, reduce your pension value by the share assigned away. If divorce is in progress, only the portion accrued during the marriage is on the table, not the whole pension.
Putting the Number on Your Balance Sheet
Start with the method your plan type dictates: vested balance for defined contribution, offered lump sum for defined benefit plans that have one, present value of the annuity for those that don’t. Then work through the reductions that apply to you — taxes always, inflation if there is no COLA, the early withdrawal penalty if you’ll access funds before 59½, the unvested share if you haven’t hit the full schedule, the PBGC cap if the plan looks fragile, and any amount already assigned by QDRO. The figure left standing is what your pension is worth to you today, and it belongs on your balance sheet alongside everything else you own.
