Short Term Treasury Portfolio: 20-year retirement

Last Update: 28 February 2023

Do you have in mind a 20 years retirement, investing in the Short Term Treasury Portfolio?

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

Key Points

Worst case scenario so far, over a 20-year time horizon, you could have withdrawn 3.462% of your initial capital each year, kept withdrawing all the time (adjusting for inflation), and you wouldn't have run out of money before 20 years.

With a 4% withdrawal strategy, you would have lived on your investiment for 20 years in the 94.14% of cases. In the 20.04% of cases, you would have preserved your initial inflation adjusted capital.

The last 20 years of the Short Term Treasury Portfolio

Over the last 20 years (last update: February 2023), the portfolio has returned 1.55% annualized, with a maximum drawdown of -5.36%.

A safe withdrawal rate would have been 4.988%.

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.
