Last Update: 30 April 2025

Do you have in mind a 40 years retirement, investing in the Golden Butterfly Portfolio?

Worst case scenario so far, over a 40-year time horizon, you could have withdrawn 3.153% of your initial capital each year, kept withdrawing all the time (adjusting for inflation), and you wouldn't have run out of money before 40 years.

With a 4% withdrawal strategy, you would have lived on your investiment for 40 years in the 78.22% of cases. In the 54.19% of cases, you would have preserved your initial inflation adjusted capital.

According to the historical returns and stats of the portfolio, which has been a sustainable withdrawal rate to live off your investiment?

The last 40 years of the Golden Butterfly Portfolio

Over the last 40 years (last update: April 2025), the portfolio has returned 8.49% annualized, with a maximum drawdown of -17.95%.

A safe withdrawal rate would have been 7.14%.

The Withdrawal Rates calculated here are annualized and refer to the initial capital (not the current!). The first month withdrawal is 1/12 of that annualized withdrawal and it's adjusted for inflation for each subsequent month.

A Perpetual Withdrawal Rate (PWR) protected the original inflation adjusted capital.

A Safe Withdrawal Rate (SWR) didn't protect the original capital, but the portfolio didn't run out of money during retirement. The portfolio went to zero exaclty at the end of the retirement period.

Withdrawals and Success Rate

If you had implemented a specific Withdrawal Strategy with the Golden Butterfly Portfolio, over 40 years, which would have been the success rate so far?

Simulations follow the same rules mentioned before. Withdrawals are expressed as yearly rates and refer to the initial capital. After that, withdrawal amount is monthly adjusted for inflation.

Success rates are calculated over all 40-year timeframes available in the data source. To focus on a specific withdrawal rate, click on the links in the table.
