Crypto FIRE Calculator
Find out how much you need to retire early using the FIRE framework. Enter your annual expenses, current savings, and expected returns to see your target number, timeline, and required monthly savings.
Your FIRE Inputs
How much you spend per year (your target lifestyle cost)
Your total investable assets today
How much you invest each month toward FIRE
Conservative: 5–7% | Aggressive: 8–12% | Crypto-heavy: 10–15%
4% is the classic rule (25× expenses). Use 3–3.5% for a more conservative approach (28–33× expenses).
At 4% withdrawal rate = 25× your annual expenses
How FIRE Works
The FIRE framework is built on two core concepts: your FIRE number (the portfolio size needed to fund your lifestyle indefinitely) and the safe withdrawal rate (how much you can draw down each year without depleting your portfolio). The classic 4% rule comes from research showing that a diversified portfolio can sustain 4% annual withdrawals over 30+ years.
FIRE Number = Annual Expenses ÷ Withdrawal Rate
(e.g., $50,000 ÷ 4% = $1,250,000)
Portfolio Growth = P × (1 + r)^n + PMT × ((1 + r)^n − 1) / r
Where: P = current savings, r = annual return, n = years, PMT = annual contributionsMonitor your FIRE journey with a crypto portfolio tracker
Knowing your FIRE number is step one. Tracking your actual portfolio growth — including crypto holdings — keeps you on course. See our top-rated portfolio trackers.

Understanding your FIRE projection
Your FIRE number is a planning target, not a guarantee. The two assumptions that most dramatically affect the result are your expected annual return and your safe withdrawal rate. A 1% change in either can shift your FIRE date by several years. Running the calculator with conservative, base, and optimistic assumptions gives you a range of outcomes to plan around.
Inflation is the most commonly underestimated variable in FIRE planning. A 4% withdrawal rate that covers your expenses today may fall short in 20 years if inflation averages 3–4% annually. Modelling inflation-adjusted withdrawals — not nominal ones — gives a more realistic picture of whether your FIRE number is sufficient.
The order in which returns occur matters as much as the average return. Retiring into a bear market and withdrawing from a declining portfolio can permanently impair your capital in ways that a later recovery cannot fully repair. This is the most significant risk for early retirees and is why conservative withdrawal rates are recommended.
Crypto assets are significantly more volatile than traditional retirement assets. A portfolio that is 50% crypto may experience 40–60% drawdowns in bear markets. Your FIRE plan should account for this by either maintaining a larger cash buffer, using a lower withdrawal rate, or reducing crypto allocation as you approach your FIRE date.
At 3% annual inflation, $50,000 of annual expenses today will require $67,000 in 10 years and $90,000 in 20 years to maintain the same purchasing power. FIRE plans that use nominal rather than real expense figures consistently underestimate the capital required for long-term financial independence.
Crypto's historical returns have been exceptional but are unlikely to persist at the same rate as the asset class matures. FIRE projections based on 30–50% annual returns are not conservative planning — they are optimistic speculation. Base-case FIRE planning should use returns closer to 8–12% annually for a diversified portfolio.
Volatility assumptions dramatically change retirement timelines. The difference between a 10% and 15% assumed annual return may seem modest, but over a 20-year accumulation period it can shift your FIRE date by 5–7 years. Running your FIRE calculation at multiple return assumptions — and planning around the conservative case — is the most resilient approach.
