US Long Term (20y+) Treasuries: 20-year retirement

Last Update: 31 March 2025

Do you have in mind a 20 years retirement, investing in the US Long Term (20y+) Treasuries asset class?

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

Worst case scenario so far, over a 20-year time horizon, you could have withdrawn 3.622% of your initial capital each year, kept withdrawing all the time (adjusting for inflation), and you wouldn't have run out of money before 20 years.

Considering the last 20 years (last update: March 2025), a safe withdrawal rate would have been 6.95%.

The last 20 years of the US Long Term (20y+) Treasuries asset class

Over the last 20 years (last update: March 2025), the asset class has returned 3.32% annualized, with a maximum drawdown of -47.74%.

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 investment didn't run out of money during retirement. The capital went to zero exaclty at the end of the retirement period.
