Realistic FIRE numbers in 2026 (with stress-test context)

“What’s a realistic FIRE number in 2026?” is really three questions: how much do you spend, what withdrawal rate are you willing to plan with, and how much path risk can you tolerate? Below are transparent worked examples — not benchmarks you must match, and not advice.

Full FIRE at common spending levels (4% and 3.5%)

• $40k spend → $1.0M at 4% · ~$1.14M at 3.5%
• $60k spend → $1.5M at 4% · ~$1.71M at 3.5%
• $80k spend → $2.0M at 4% · ~$2.29M at 3.5%
• $100k spend → $2.5M at 4% · ~$2.86M at 3.5%

The jump from 4% to 3.5% is large in dollars because the multiplier moves from 25× to about 28.6×. Early retirees often explore that band precisely because horizons are long and sequence risk is less forgiving.

Coast examples (age 35 → 65, 5% real)

• Full FIRE $1.5M → coast ≈ $1.5M ÷ (1.05)^30 ≈ $347k
• Full FIRE $2.0M → coast ≈ $463k
• Same $1.5M target at 4% real → coast ≈ $462k (lower r raises today’s bar)

Coast numbers look “small” next to full FIRE because they are not funding early retirement spending from the portfolio. They only ask whether growth may finish the nest egg by a traditional retirement age if contributions stop.

Barista examples ($60k spend, 4% SWR)

• $0 work income → $1.5M (full FIRE)
• $15k work income → gap $45k → $1.125M
• $25k work income → gap $35k → $875k
• $40k work income → gap $20k → $500k

Barista math only helps if the work income is realistic after taxes, benefits cliffs, and dry spells. Semi-retirement is a cash-flow design, not a slogan.

Add stress-test context

A constant 5% real path to a $1.5M target can look tidy while a 1,000-path stress test with 15% volatility shows a wide band of terminal wealth. Success rate is the share of simulated paths that finish at or above target under the toy model — not the probability that your life works out. Use it to see whether you need more surplus, more savings years, or a lower lifestyle assumption.

A 2026 planning checklist

• Write annual spending in today’s dollars (include healthcare realistically).
• Compute FIRE at 3%, 3.5%, and 4%.
• Compute Coast with 4% and 5% real over your true horizon.
• If semi-retiring, stress work income at 50% of the hopeful number.
• Run the free sequence stress test on Coast/Years and note p10 vs median.
• Export CSV or share the URL so a partner sees the same assumptions.
