Start with credible inputs
Use realistic assets, contributions, spending, cash reserves and recovery assumptions. Test a difficult but plausible scenario rather than a dramatic number chosen only to frighten yourself.
FIRE FOUNDATIONS · LEVEL 3
Can your FIRE plan survive a bad start?
Compare normal conditions with an early market fall and an income interruption. See what gives your plan more room to recover.
YOUR FIRE PLAN
Test the plan before life tests it.
Use today's dollars. This is a simplified planning illustration, not investment or tax advice.
THE WEAKEST LINK IN YOUR PLAN
Early market dropWithout changes, funds run out after about 31.5 years.NormalResilient35+ years7% nominal return, 2% annual spending inflation and $500/month flexible income.
Market dropTight31.5 years-30% for 1 year, then 7% nominal return while spending rises 2%/year.
Income pauseResilient35+ years$500/month paused for 2 years; costs +15% for 3 years.
THREE STRESS PATHS
What happens to available capital?
Each path includes your planned withdrawals. The reserve is used only during a stressed period.

The model uses your expected return after inflation. It does not model taxes, fees, changing asset allocation, pensions, healthcare shocks or every market path—use it to ask better questions, not to certify a plan.
HOW TO READ THIS
Resilience is more than a withdrawal rate.
Markets, costs and income do not move one at a time. This tool uses deliberately simple stress scenarios to show why flexible spending, a cash buffer and the ability to earn some income can matter alongside the portfolio itself.
FIRE RESILIENCE CALCULATOR EXPLAINED
Can your FIRE plan survive an early market crash or income interruption?
A resilient FIRE plan can absorb bad timing without forcing an immediate permanent change. The stress test compares a baseline with an early decline and a period of higher costs or interrupted income.
How to interpret the calculator result
Read the result in context
Focus on the funding gap, recovery time and remaining buffer—not only the final balance. A plan that recovers slowly may still be workable if spending and income are flexible.
Turn it into a decision
Use the weakest scenario to decide whether to add cash, reduce fixed costs, delay the date or preserve some earning capacity.
COMMON QUESTIONS
Questions about this FIRE resilience calculator.
What makes a FIRE plan resilient?
Useful buffers include flexible spending, cash for near-term needs, diversified assets, insurance and the option to earn some income.
Is a stress test a probability forecast?
No. It is a scenario designed to expose fragile assumptions. It does not predict when a crash, cost increase or income interruption will happen.
EVIDENCE SNAPSHOT
