These are hypothetical constant-growth scenarios, not Power Law, Stock-to-Flow, or Rainbow Chart forecasts. All assume positive returns and omit volatility, fees, taxes, and inflation. Bitcoin can lose value. The full calculator uses different methods: a market-price-anchored time power function for Power Law and a halving-cycle growth heuristic for Stock-to-Flow, not PlanB's original regression. Results will differ. No returns or retirement date are guaranteed.

How the Calculation Works
Step 1: Financial Freedom Number. Using the 4% rule from the FIRE movement, we calculate that you need 25 times your annual expenses. With $15,000/month ($180,000/year), your target is $4,500,000.
Step 2: Bitcoin Equivalent. At today's Bitcoin price of $100,000, that equals 45.00 BTC.
Step 3: DCA Projection. Starting from zero BTC, we convert each annual compound rate to a monthly rate using (1 + annual rate)^(1/12) − 1. We buy BTC at each month's projected price and compare the portfolio to a fixed target of $4,500,000. The 4% guideline is not validated for a Bitcoin-only portfolio.
Important: These are hypothetical fixed-growth calculations, not named-model forecasts. Bitcoin is volatile and past performance doesn't guarantee future results. Always consult a financial advisor.
