The calculator uses two phases to simulate your retirement finances.

The first phase is the accumulation phase. The system uses your current BTC value as the starting point, adds the annual investment each year, and projects to the retirement age based on the set annual BTC growth rate.

The second phase is the withdrawal phase. From the retirement age to life expectancy, the system adjusts annual living expenses for inflation and calculates how much BTC must be sold to cover expenses, while accounting for capital gains tax; the remaining holdings continue to grow at the assumed growth rate.

If your assets can sustain you through your expected lifespan, the system will display that you can retire; otherwise, it will indicate that they are insufficient.

No. This calculator is provided for retirement scenario estimation and comparison purposes only and does not constitute investment, tax, or financial advice. Actual planning should take into account your personal income situation, risk tolerance, and professional advice.

The calculator estimates the BTC amount required for retirement and the difference between your current holdings and the required amount based on your age, investment amount, expense assumptions, and growth assumptions.

The tool simulates a scenario where you continue contributing annually and evaluates whether the long-term accumulation would be sufficient to cover retirement expenses.

Retirement planning follows a long-term compounding model. Small differences in growth rates are amplified over many years, resulting in significant differences in outcomes.

This does not indicate failure. It simply means that, under the current assumptions, a funding gap remains, which can typically be addressed by increasing investments, delaying retirement, or adjusting expenses.

No. This price is a model-derived value projected based on your specified growth rate, used to calculate retirement scenarios, and is not equivalent to a market forecast.

If you need to sell BTC during retirement to cover expenses, taxes will affect the amount you can actually use. Ignoring taxes often leads to an overestimation of retirement sustainability.

It represents the amount of BTC still required to reach your retirement target under the current settings, and can serve as a reference metric for adjusting your allocation or expense assumptions.

It is recommended to run calculations using both approaches. Comparing different scenarios can help you better understand the possible range of outcomes.

Tips

It is recommended to first run the calculation using conservative assumptions and a small allocation, then adjust gradually.

Please pay special attention to the impact of inflation and taxation on long-term retirement expenses.
