Safe Withdrawal Rate (SWR) is a critical concept in retirement planning, particularly within the financial independence community. It refers to the percentage of your savings that you can withdraw each year without running out of money in retirement.
History of SWR
The concept gained prominence with the publication of a study by William Bengen in 1994. He introduced the 4% rule, which found that retirees could withdraw 4% of their portfolio in the first year of retirement and adjust that amount for inflation each year, with a high probability of not outliving their savings over a 30-year retirement period.
The Trinity Study, published by three professors from Trinity University in 1998, further cemented the concept of the SWR by providing a broader set of data and affirming Bengen’s findings. They also explored various withdrawal rates and portfolio compositions, offering a more nuanced understanding of how different strategies could impact one’s retirement savings longevity.
To calculate your personal SWR, you should:
- Estimate Your Retirement Budget: Determine your annual expenses in retirement.
- Assess Your Portfolio: Evaluate the total value of your investment portfolio.
- Choose a Withdrawal Rate: Decide on a withdrawal rate that suits your risk tolerance and retirement span.
- Calculate Annual Withdrawal: Multiply your portfolio value by the chosen withdrawal rate to get your annual withdrawal amount.
Adjustments and Considerations
- Inflation: Adjust withdrawals to account for inflation.
- Market Volatility: Be prepared to lower withdrawals during market downturns.
- Longevity Risk: If you expect a longer retirement, consider a lower SWR.
- Portfolio Composition: A mix of stocks and bonds can influence the ideal SWR.

These concepts are vital for anyone looking to achieve financial independence and retire early (FIRE). By applying these principles, you can plan a retirement strategy that balances the enjoyment of your golden years with the peace of mind that your savings will last.
Remember, SWR is not a one-size-fits-all answer. It’s a starting point requiring ongoing management and reviews as you retire. Consider consulting with a financial advisor to tailor your retirement plan to your needs.
