Estimate how income tax, capital gains tax, retirement account access, and contribution limits affect spendable cash.
Safe withdrawal rate
Choose a safe withdrawal rate for FIRE in United States by comparing 4%, 3.5%, and 3% scenarios, spending flexibility, time horizon, and risk buffers.
A FIRE number is only useful when the local assumptions behind it are realistic. Use this checklist to adapt the calculator to United States before relying on the result.
Estimate how income tax, capital gains tax, retirement account access, and contribution limits affect spendable cash.
Decide whether social security, public pension, or other benefits are a backup, a delayed income source, or excluded from the base case.
Model insurance premiums, out-of-pocket medical costs, and long-term care separately, especially for early retirement years.
Treat a primary home differently from investable assets unless it can be sold, rented, downsized, or borrowed against.
Check whether spending, income, and investments are exposed to different inflation rates or currencies.
ChooseFIRE can structure the calculation, but it cannot know your tax filing status, benefits, insurance plan, family obligations, or local policy changes. Revisit the assumptions whenever your region, currency, or residency plan changes.
A safe withdrawal rate is the percentage of your portfolio you plan to withdraw each year while trying to avoid running out of money. Lower rates require more assets but add resilience.
Withdrawal rate = annual withdrawals Γ· portfolio value
The same annual spending produces very different FIRE numbers at different rates. 48,000 of annual spending needs 1,200,000 at 4%, 1,371,429 at 3.5%, and 1,600,000 at 3%.
If a portfolio is 1,000,000, a 4% withdrawal is 40,000 in year one. A 3.5% withdrawal is 35,000, leaving more room for market volatility.
A retirement that may last 50 years usually needs more caution than a traditional 30-year retirement.
Plans with adjustable travel, housing, or discretionary spending can tolerate downturns better than rigid budgets.
Part-time work, pensions, rental income, cash reserves, or delayed withdrawals can support a higher risk tolerance.
No withdrawal rate is universally safe. Recalculate when markets, tax rules, health costs, family needs, or spending expectations change.
