Last Update: 30 September 2024
You decided on a 4% withdrawal strategy and invested in the Commodities asset class: how likely, so far, your investment would have been enough for your retirement?.
In this post, we will simulate different retirement timeframes and check the sustainability of the withdrawal rate, using actual historical series.
Success Rate of a 4% Withdrawal Strategy
Let's calculate the success rate of a 4% Withdrawal Strategy, on the Commodities asset class. Would you have also saved a portion of your invested capital, at the end of your retirement?
As usual, the withdrawal is expressed as a yearly rate and refers to the initial capital. After that, the withdrawal amount is monthly adjusted for inflation.
For instance, assuming a 20 years retirement, the algorithm will cover each 20 year timeframe starting at every possible month in the given period between the start and end month.
Here's how simulations work (each simulation is based on actual asset class returns, in US dollars):
- At the beginning, you start with a certain amount of money invested in the portfolio (i.e. the initial invested capital).
- Each month, money is withdrawn from the portfolio. The withdrawal rate is calculated based on the initial withdrawn, annualized.
- Each month, portfolio value is updated, based on the asset classes returns (dividends are supposed to be reinvested).
- Each month, portfolio is rebalanced, to reset to the original weight of the assets (applicable only if portfolio contains at least 2 assets).
- Each month, the withdrawal is adjusted for inflation (US Inflation is used for simulation).
The Perpetual Withdrawal Rate (PWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, preserving the original invested capital, adjusted for inflation too.
The Safe Withdrawal Rate (SWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, without the portfolio running out of money.

We are calculating the success rate over all the past N-year timeframes, on actual historical data, also focusing on how much capital (inflation adjusted) will remain after the retirement.
