Half the Portfolio, Twice the Certainty
A 40-year-old government employee is building toward FIRE at 52, and her biggest retirement asset never shows up on a balance sheet.
Most FIRE calculations start with a target number. This one starts with a guarantee. When your most valuable retirement asset is a defined-benefit pension, the entire savings calculus shifts.
At 40, she has accumulated roughly $750,000 in net worth: a 401k and 457 plan combined at $200,000, a taxable brokerage at $150,000, and $400,000 in home equity, with 12 years remaining before her target retirement age. On paper that reads as a FIRE journey still in the middle stages. The number changes when you add the pension. She works in a government or public-sector role (confirmed by the 457b plan, which is exclusive to state and local government employees), and at age 52 she will begin receiving $40,000 per year for life. Capitalized at a 4% withdrawal rate, that pension represents roughly $1,000,000 in present value terms, invisible on every net worth tracker she uses. Her true retirement security sits closer to $1.75 million than $750k, and she knows it. Her question to the FIRE community is the right one: with a guaranteed income floor arriving at retirement, how much additional portfolio does she actually need, and how should she sequence the assets she has?
"The pension covers the basics at 52. I just need my investments to bridge the early years and cover anything above the baseline."
Takeaways
A pension is a bond you cannot buy. At a 4% withdrawal rate, $40,000 per year is the economic equivalent of $1,000,000 in portfolio assets. It does not fluctuate with market conditions, does not require sequence-of-returns management, and does not run out. Government workers with defined-benefit pensions are routinely more retirement-secure than their stated net worth implies.
The 457b is a hidden early-retirement superpower. Unlike 401k and IRA accounts, 457b plans carry no 10% early withdrawal penalty. Distributions are taxed as ordinary income, but they can begin the day she separates from her employer at any age. For someone planning to retire at 52, this creates a penalty-free bridge without the Roth conversion ladders and 72(t) elections most early retirees have to engineer.
Home equity is the weakest link in her composition. With $400,000 of her $750,000 in illiquid home equity and only $350,000 in investable assets, the sequencing question matters more than the total. If she needs cash in the early retirement years before her pension and Social Security stack, she is drawing on a relatively thin pool of liquid assets. Paying attention to liquidity, not just net worth totals, is the discipline this profile highlights.
Guaranteed income enables higher-growth investing elsewhere. A pension floor changes the risk tolerance equation for every other account. When $40,000 per year is guaranteed regardless of portfolio performance, she can hold more equity risk in her brokerage and 457 without the psychological and financial pressure of a market downturn derailing her entire plan. Certainty in one bucket buys freedom in the others.
