BTC To Retire
What is BTC To Retire?
A personal Bitcoin planning toolkit for asking better long-term money questions.
This is a small set of Bitcoin calculators for people who want to pressure-test retirement, taxes, accumulation, debt, and long-horizon planning without pretending any model knows the future.
The point is to make assumptions visible. Change the inputs, compare the outputs, and use the result as a better starting point for thinking, not as a final answer.
Built For
Bitcoin holders thinking about when a stack becomes enough, how to avoid unnecessary selling, and how taxes or debt change the answer.
Not Built For
Financial advice, tax filing, insurance illustrations, or certainty. The calculators simplify real-world rules and leave plenty of room for professional judgment.
Start With The Question
Each calculator is a different lens on the same basic problem: preserving purchasing power.
How much BTC would I need to retire?
Estimate retirement needs under salary, inflation, withdrawal-rate, and power-law assumptions.
How should different account types be spent down?
Model taxable, Traditional IRA, and Roth sequencing with simplified federal tax assumptions.
What if I borrow against a policy to buy BTC?
Simulate policy-loan cycles that buy BTC, repay, and repeat.
Should I DCA or buy a lump sum?
Compare recurring BTC buys against a one-time purchase.
Should I sell BTC or borrow against it?
Compare tax drag, debt cost, and future retained stack value.
Should extra cash pay down mortgage debt or buy BTC?
Compare debt payoff against BTC accumulation over time.
What model is being used?
Review the Bitcoin power-law assumptions used across long-term calculators.
Methodology
Long-term BTC projections use configurable power-law bands from shared constants. These are scenario tools, not forecasts. Other calculators use fixed rates, embedded historical data, Monte Carlo, live spot pricing, or direct user-entered assumptions.
Tax, insurance, retirement, and debt calculations are intentionally simplified. They are useful for seeing tradeoffs quickly, but not for filing taxes, designing insurance, or making irreversible decisions.
