Have you ever thought of how much you can withdraw monthly/yearly from your portfolio, during your retirement?

At first, figure out how long your retirement might be. Now choose:
• Do you want to preserve your initial capital, adjusted for inflation?
• You don't care about eating away all your invested capital at the end of your retirement?

In the first case, look at the Perpetual Withdrawal Rate
The Perpetual Withdrawal Rate (PWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, preserving the original invested capital, adjusted for inflation too.

In the second case, look at the Safe Withdrawal Rate
The Safe Withdrawal Rate (SWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, without the portfolio running out of money.

Each N-years timeframe has been considered to calculate withdrawal rates.
For instance, with a 20 years timeframe, the algorithm is covering each 20 year timeframe starting from the beginning, and continuing month after month.

Each N-years timeframe has been considered to calculate withdrawal rates.

Each N-years timeframe has been considered to calculate withdrawal rates.
For instance, with a 20 years timeframe, the algorithm is covering each 20 year timeframe starting from the beginning, and continuing month after month.

PWRs and SWRs are calculated over timeframes ending at March 2024.
For instance, with the 20 years timeframe, the algorithm is calculating withdrawal rates from April 2004 to March 2024.

The algorithm calculates the chance of success of a initial withdrawal rate, whose amount in dollars is adjusted monthly for inflation. The algorithm tries a retirement simulation, starting at every possible month in the given period.
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• Each month, money is withdrawn from the portfolio. The withdrawal rate is calculated based on the initial withdrawn, annualized.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 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.

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.
