Free Bitcoin retirement planning tool using the Power Law support line - Calculate how much BTC you need to retire comfortably
This calculator uses the Bitcoin Power Law Support Line - the most conservative price model for Bitcoin retirement planning. Here's why this approach is ideal for careful retirement planning:
The support line represents Bitcoin's historical "floor" price during the deepest bear markets. By using this conservative baseline, you're planning for the worst-case scenarios.
Our model uses only 42% of the Power Law fair value - essentially assuming Bitcoin will trade at bear market lows throughout your retirement. This extreme conservatism provides a safety margin.
The Bitcoin Power Law has held true since 2009, with the support line acting as a reliable floor. Even during the worst crashes, Bitcoin has rarely broken below this level.
If Bitcoin performs better than the support line (which it historically has 95%+ of the time), you'll have significantly more wealth than planned - a pleasant surprise rather than a shortfall.
This depends on your desired annual withdrawal amount and retirement timeline. Our calculator uses the conservative Power Law support line to estimate the minimum BTC needed. Most people need between 1-50 BTC depending on their lifestyle and location.
The Bitcoin Power Law is a mathematical model that has accurately predicted Bitcoin's price trajectory since 2009. It shows Bitcoin's price follows a power law relationship with time, making it useful for long-term planning.
The support line represents Bitcoin's historical floor price during bear markets. Using this conservative estimate ensures your retirement plan works even if Bitcoin underperforms for extended periods.
This calculator uses historical data and conservative assumptions. While no model can predict the future perfectly, the Power Law has been remarkably accurate since 2009. This tool is for educational purposes only.
Yes! Our calculator includes capital gains tax calculations to give you a more realistic estimate of your net withdrawal amount. Tax rates vary by jurisdiction, so consult a tax professional for your specific situation.
The calculator accounts for inflation by increasing your annual withdrawal target each year. This ensures your purchasing power remains constant throughout retirement.
