FIRE Planner
Calculate when you can reach Financial Independence & Retire Early.
FIRE Retirement Planner Guide
Learn how the FIRE number, savings rate, and safe withdrawal rate work together so you can estimate an early-retirement timeline with clearer assumptions.
How to use this planner
Enter your current net worth, annual income, and annual expenses. Set a savings rate that reflects what you can actually sustain, then choose an expected investment return and safe withdrawal rate (SWR). The calculator estimates your FIRE target (often near 25× annual expenses at a 4% SWR) and how many years it may take to reach that target under your assumptions.
Worked example
If annual expenses are $36,000 and you use a 4% SWR, a common FIRE number is $36,000 ÷ 0.04 = $900,000. With $50,000 already invested, a high savings rate, and an 8% assumed return, the timeline can shrink into the teens of years. Lowering expenses reduces the target itself, while raising savings accelerates progress from both sides—more invested capital and a smaller retirement need.
What the outputs mean
FIRE Number is the portfolio size suggested by your expenses and SWR. Years to FIRE is a projection, not a promise. Annual Savings shows how much capital you are adding based on income and savings rate. Use the chart to see whether your path is front-loaded by high savings or delayed by high spending.
Planning tips
Stress-test with lower returns and a more conservative SWR (for example 3–3.5%) if you want a larger safety margin. Include healthcare, housing, and inflation in expense estimates. Revisit the plan after major life changes. FIRE is a framework for financial independence, not a requirement to stop all work forever.
What does FIRE mean?
FIRE stands for Financial Independence, Retire Early. The idea is to save and invest aggressively so portfolio returns can cover living costs without relying on a traditional paycheck.
What is the Rule of 25?
A popular shortcut: multiply annual spending by 25 to estimate a nest egg that may support withdrawals near 4% per year. It is a starting point, not a guarantee.
What is a safe withdrawal rate?
SWR is the percentage of portfolio value you plan to withdraw annually. Lower SWRs require larger portfolios but can reduce the risk of running out of money.
Why is savings rate so powerful?
A higher savings rate increases invested capital and often reduces future expenses, which lowers the FIRE number and shortens the timeline simultaneously.
Should I assume 8% returns forever?
Historical averages are not future guarantees. Run optimistic and pessimistic cases so your plan is resilient if markets underperform for long stretches.
Is this retirement advice?
No. This is an educational simulator. Tax rules, pensions, Social Security, and personal risk tolerance can change the right strategy for you.
Disclaimer: FIRE projections ignore many real-world variables such as sequence-of-returns risk, taxes, healthcare costs, and career interruptions. Treat results as planning scenarios only.
