Should I include Social Security in my FIRE number calculation?

For most FIRE investors planning to retire before 62, Social Security should be treated as a bonus — not a foundation. The safest approach is to calculate your FIRE number based on 100% portfolio withdrawals, then model Social Security as a supplemental income source that reduces your withdrawal rate after claiming age. Given the 2032 trust fund depletion timeline, conservative FIRE planners should also apply a 20-28% reduction to projected benefits as a stress-test scenario.

What happens to Social Security if the trust fund runs out in 2032?

If the OASI trust fund depletes in 2032 as currently projected by the SSA trustees, the Social Security Administration would be legally required to reduce all benefits to whatever can be funded by current payroll tax revenues — estimated at 72-80% of scheduled benefits. This is approximately a 20-28% across-the-board cut, not a total elimination of benefits. CNBC reported in June 2026 that this could average $500/month less for retirees.

How do I calculate my FIRE number without Social Security?

Your FIRE number without Social Security = Annual expenses × 25 (at the 4% withdrawal rate). If your annual expenses are $60,000/year, your FIRE number is $1.5M — and that's your full portfolio target, with no assumed Social Security income reducing it. This is the most conservative and risk-free FIRE calculation. Use our FIRE Calculator to model this scenario alongside a partial-SS scenario for comparison.

How does DOGE's SSA workforce reduction affect Social Security payments?

DOGE's reduction of ~7,000 SSA employees affects the agency's ability to process claims, answer calls, and maintain its technology infrastructure — but does not directly change benefit amounts. However, reduced staffing increases benefit processing delays, overpayment error rates, and the risk of system failures. For FIRE investors, the operational risk is real for people claiming Social Security soon; for FIRE investors years away from claiming, the benefit calculation and trust fund timeline are the more important variables.

What is the best Social Security strategy for FIRE investors?

The optimal strategy for most FIRE investors is: (1) Build your FIRE number assuming zero Social Security — this is your conservative floor. (2) Delay Social Security claiming to age 70 if health allows — this increases your benefit by ~76% vs. claiming at 62, and a 28% cut to a 70-age benefit is still more than a 28% cut to a 62-age benefit. (3) Treat Social Security as a flexible wildcard — model 0%, 50%, and 75% of projected benefits in your retirement scenarios. The one that matters most is the 0% scenario: if that works, everything else is upside.

FIRE Without Social Security: The 2032 Deadline

← Back to Blog

The two most important Social Security numbers in 2026 are not your projected monthly benefit.

They are: 2032 (the year the OASI trust fund is now projected to deplete) and 28% (the across-the-board benefit cut that would follow if Congress does nothing before then).

For FIRE investors — especially those planning to retire in their 30s, 40s, or early 50s — Social Security has always been a planning uncertainty. In 2026, two new variables have made that uncertainty sharper: the trust fund depletion timeline moved up a year, and DOGE's 7,000-employee workforce reduction at the SSA has added operational risk on top of the financial one.

Here is how to build a FIRE plan that survives all of it.

The Updated Trust Fund Timeline

The SSA Board of Trustees' 2026 annual report updated the OASI depletion projection from 2033 to 2032 — one year earlier than last year's estimate.

The SSA's own testimony to the Senate Budget Committee in March 2026 confirmed what CNBC reported on June 3, 2026: if the trust fund depletes, the SSA would be legally required to reduce benefits to whatever current payroll tax revenues can fund. At projected 2032 revenue levels, that is approximately 72–80% of scheduled benefits — a cut of 20–28%.

In dollar terms, the June 2026 CNBC analysis estimated this would average $500/month less for current retirees. For a FIRE investor expecting $1,800/month at 67 in today's dollars, a 28% cut means $1,296/month instead.

The key question for FIRE investors: Does a 28% Social Security cut break your plan?

If your FIRE number is already calculated without Social Security, the answer is no — that cut is already priced in. If your FIRE plan relies on full Social Security income, you may be under-capitalized.

The DOGE Factor: Operational Risk on Top of Financial Risk

Separate from the trust fund timeline, DOGE's reduction of approximately 7,000 SSA employees in 2026 has introduced operational risk that affects how and when benefits are processed.

The SSA's own data shows:

Average wait times for new benefit claims have increased
Office closures in rural areas mean longer travel for in-person assistance
IT staffing reductions have affected the agency's ability to modernize legacy systems

For FIRE investors who are already retired and claiming Social Security, the operational risks are real and present. For FIRE investors still in accumulation — likely 10-30 years from claiming — the operational disruptions matter less than the underlying financial question: will the benefits be there, and at what level?

The honest answer from the trustees' 2026 data: Social Security will almost certainly exist in some form, but the level of benefits after 2032 depends entirely on whether Congress acts before the trust fund depletes.

The Three Ways to Model Social Security in Your FIRE Plan

Rather than betting on one outcome, build your FIRE plan around three scenarios:

Scenario 1: Zero Social Security (Conservative Floor)

Calculate your FIRE number assuming $0 in Social Security income, ever.

Why: This is your worst-case scenario and the cleanest planning baseline. If your FIRE number works with no Social Security at all, every dollar of Social Security you eventually receive is pure upside — a buffer against longevity risk, healthcare cost inflation, or a second FIRE number for a spouse.

How to calculate: Annual expenses × 25 (at the 4% rule). If you plan to spend $70,000/year in retirement, your conservative FIRE number is $1,750,000.

Use the FIRE Calculator to model this scenario and find your target retirement date.

Scenario 2: 50% of Projected Benefits (Moderate Scenario)

Pull your projected monthly benefit from your SSA statement at full retirement age (67 for most FIRE investors). Apply a 50% haircut.

Why: This is a reasonable middle ground that accounts for both trust fund risk and the political reality that some benefit restoration is likely even if Congress acts imperfectly.

How to calculate: If your projected benefit at 67 is $2,200/month ($26,400/year), model $1,100/month ($13,200/year) in your FIRE plan. This reduces your required portfolio withdrawal by $13,200/year — and your FIRE number by approximately $330,000 (at the 4% rule).

Caution: Don't count on a specific number here. The 50% scenario is an approximation, not a guarantee.

Scenario 3: 75% of Projected Benefits (Optimistic-Conservative Scenario)

Apply a 25% haircut to your projected benefits to account for the likely trust fund depletion cut, even if Congress passes partial fixes.

Why: The 20–28% benefit cut from trust fund depletion is the worst case; with any Congressional action, actual cuts might be 10–20%. Modeling 75% of projected benefits accounts for imperfect Congressional fixes without being as pessimistic as the 0% scenario.

The FIRE Hierarchy: Where Social Security Fits

Here is the right way to think about Social Security in FIRE planning:

Your FIRE Number (calculated at 0% SS)
    ↓ This is your target — non-negotiable
Portfolio at FIRE
    ↓ Covers 100% of expenses from retirement to ~67
Social Security at 67 (at 50-75% of projected)
    ↓ Reduces withdrawal rate; extends portfolio longevity
Social Security at 70 (at 50-75% of projected)
    ↓ Maximum claiming benefit; converts to larger longevity buffer

The structural insight: Social Security is a longevity hedge, not a retirement income source, for most FIRE investors who retire in their 30s-50s.

If you retire at 42, you have 20-28 years before claiming Social Security — during which your portfolio funds 100% of expenses. After claiming, Social Security reduces your withdrawal rate, which extends your portfolio's lifespan into your 80s and 90s. It's a longevity buffer, not a foundation.

The FIRE investor who doesn't need Social Security to survive but benefits significantly from it if it shows up is in the ideal position. Build your plan to reach that position.

The Delay Strategy: Why Claiming at 70 Is Still the Best FIRE Move

In a trust fund depletion scenario, claiming at 70 vs. 62 remains the superior strategy for most FIRE investors who can afford to delay.

Here's why: A 28% benefit cut applies to your base monthly benefit — not to your claiming-age multiplier.

Example (in today's dollars):

Projected benefit at 62: $1,400/month
Projected benefit at 67 (FRA): $2,000/month
Projected benefit at 70: $2,480/month

After a 28% trust fund cut:

At 62: $1,008/month
At 67: $1,440/month
At 70: $1,786/month

A 28% cut to the age-70 benefit ($1,786) still exceeds a 28% cut to the age-62 benefit ($1,008) by $778/month. The delay premium survives the haircut.

The FIRE-specific constraint: You need your portfolio to cover expenses from early retirement through age 70 with no Social Security. The Withdrawal Strategy Calculator can model whether your portfolio can support 28-35 years of withdrawals before Social Security kicks in.

How DOGE Changes the Claiming Strategy (Near-Term Retirees)

For FIRE investors who plan to claim Social Security within the next 1-3 years, the operational disruptions at SSA matter more than they do for long-horizon planners.

Practical steps:

File early if you're within 3 months of your target claiming date — processing delays are running longer than pre-DOGE timelines
Create a my Social Security account now at ssa.gov if you haven't — account setup is slower than it used to be, and you need it for online management
Request benefit estimates in writing from SSA as a paper backup — online estimates depend on SSA systems being current
If you're in a rural area, identify your nearest SSA office before it closes; the DOGE closure program has affected rural offices disproportionately

For FIRE investors in accumulation with a decade+ before claiming, these operational issues don't change your FIRE math — just stay aware that the process may be more friction-heavy when you get there.

Recalculate Your FIRE Number Right Now

If your current FIRE plan includes full Social Security as a line-item income source, run this test today:

Remove Social Security entirely from your income assumptions in the FIRE Calculator
Calculate how much more you need to save
Calculate how many more years of work that requires
Ask: is the gap between "full SS" and "zero SS" worth the planning risk?

For most FIRE investors, the additional savings required to remove Social Security from the plan — typically $200,000–$500,000 depending on projected benefit and timeline — is achievable and worth the certainty. The confidence of knowing your plan survives the 2032 scenario without any Congressional action is valuable.

For others, particularly late-career FIRE investors within 5-10 years of retirement who have already saved significantly, a 50–75% Social Security assumption may be a reasonable planning position — with a backup plan for the deficit if benefits are cut.

The Bottom Line: Treat Social Security as a Bonus

The practical FIRE principle for 2026 and beyond:

Plan as if Social Security doesn't exist. Retire when your portfolio can sustain you without it. Then treat Social Security — at whatever level it arrives — as a bonus that funds longevity, healthcare, or a higher standard of living in late retirement.

This is not pessimism. It's the cleanest FIRE math, the lowest planning risk, and the most resilient position in any trust fund scenario.

A FIRE investor who builds to a $1.5M portfolio with no Social Security in the model, and then receives $1,400/month starting at 70, has unlocked an additional ~$350,000 in lifetime income that further extends their already-sustainable plan.

That's the best-case FIRE scenario: a plan that works without Social Security and is made better by whatever Social Security actually delivers.
