Frequently Asked Questions
Q: What is the 4% rule?
A guideline suggesting you can withdraw 4% of your retirement portfolio annually with a low risk of running out of money over a ~30-year retirement.
Q: What does FIRE stand for?
Financial Independence, Retire Early — a movement focused on aggressive saving to reach retirement-level assets well before traditional retirement age.
Q: What's a 25x number?
Your annual expenses multiplied by 25, roughly the portfolio size needed to sustain 4% annual withdrawals.
Q: Is the 4% rule still considered reliable?
It remains a widely used starting point, though many planners now suggest more conservative or flexible withdrawal strategies.
Q: How does this calculator estimate my nest egg?
It projects your current savings and contributions forward using assumed growth rates to a target retirement age.
Q: Does this account for Social Security?
This calculator focuses on your personal savings; Social Security should be factored in separately as an income source.
Q: What's the difference between FIRE and traditional retirement planning?
FIRE typically targets a much earlier retirement age and often a leaner or more aggressive savings rate.
Q: How does inflation affect my retirement number?
Rising costs over time mean your future expenses will likely be higher than today's — build in an inflation buffer.
Q: Should my withdrawal rate change once retired?
Many retirees adjust withdrawals based on market performance and expenses rather than sticking rigidly to one fixed rate.
Q: What if I want to retire earlier than my current savings rate allows?
Increasing your savings rate or income, or reducing planned retirement expenses, are the primary levers to accelerate your timeline.
