Bitcoin Retirement Calculator — How it Works?

The Bitcoin Retirement Calculator projects how much BTC you need to accumulate to ensure a safe monthly income in the future. It combines macroeconomic Bitcoin price trajectories, Base, Bull, and Bear scenarios, inflation, life expectancy, and your monthly contribution in BTC or sats.

By entering your age, retirement age, desired income, inflation, and safe withdrawal rate (SWR), the model calculates:

  • BTC accumulated until retirement
  • Nominal patrimony value in each scenario
  • Estimated monthly income, adjusted for inflation
  • Comparison with your income goal
  • Year-by-year projection (chart and table)
  • Impact of macro events (ETFs, liquidity, regulation, recession, etc.)

The goal is to show, in a clear and auditable way, your potential future purchasing power using Bitcoin as a long-term asset.

What to expect from results

The scenarios show three possible trajectories:

  • Base – neutral projection
  • Bull – accelerated adoption
  • Bear – adverse environment

The report shows:

  • Final patrimony in BTC and your currency
  • Estimated monthly income by 4% rule and Equal Slices method
  • Whether your financial goal is met or not
  • A clear chart of your patrimony evolution until 90 years old

You see exactly how much BTC you need to accumulate to live safely — and how different macroeconomic conditions can affect your plans.

Important Notice (Disclaimer)

This calculator is an educational financial planning tool and does not constitute investment advice, financial consulting, or guarantee of future results.

Bitcoin is a volatile asset and all scenarios are hypothetical simulations. Always review your decisions with a qualified professional and practice good self-custody, storing BTC safely.

📌 Model Notes and Anchors

This calculator combines a transparent price trajectory model with macroeconomic toggles and two retirement spending methods. Everything below is editable and designed to be easy to audit.

This tool is for scenario planning; it is not investment advice. Edit parameters to reflect your own view.

Price Trajectory Formula

Anchor ranges in 2028, 2033, 2040, 2050, and 2075 for Base, Bull, and Bear represent directional midpoints based on widely discussed scenarios (ETF adoption, regulatory clarity, reserve diversification, miner economics).

Logarithmic interpolation: we calculate the compound annual growth rate (CAGR) between adjacent anchors and project to your retirement year.

CAGR = (Pt2 / Pt1)^(1/(t2−t1)) − 1
Pret = Pt1 · (1 + CAGR)^(ret−t1)

Macro Toggles Logic

Macro multipliers apply multiplicative adjustments per scenario. Example: if Base scenario has +10% ETF flows and -15% tight liquidity, the net multiplier is 1.10 × 0.85 = 0.935.

  • Strong ETF flows: raises Base/Bull more than Bear.
  • Regulatory clarity: reduces tail risk (Bear).
  • Sovereign Reserves: symbolic but powerful adoption (Bull).
  • Energy and Mining: reduces operational risk.
  • Global Liquidity: correlation with risk assets.

Current Anchors (USD)

  • 2028: Base $225k, Bull $450k, Bear $115k
  • 2033: Base $425k, Bull $1.05M, Bear $185k
  • 2040: Base $800k, Bull $3.25M, Bear $350k
  • 2050: Base $1.9M, Bull $10M, Bear $650k
  • 2075: Base $3M, Bull $30M, Bear $550k

Portfolio Math

BTC at retirement = Current BTC + (Annual buys × Years).

Portfolio = Final BTC × Price in Scenario.

*All spending values are brought to Present Value (discounted by inflation) to reflect today's purchasing power.
