About this calculator
The FIRE Withdrawal Rate is a financial planning strategy that aims to determine the annual withdrawal percentage from an investment portfolio to ensure a sustainable retirement. The 4% rule is one of the most well-known and widely used, suggesting that an annual withdrawal of 4% of the total portfolio value can be sustainable in the long term.
This strategy works based on the idea that the investment portfolio generates returns sufficient to cover inflation and portfolio growth over time. The formula behind this rule is simple: if you have a portfolio of $1 million, the annual withdrawal would be $40,000, or 4% of the total.
It's important to use this calculator during financial planning, especially when evaluating the viability of your investment portfolio for retirement. Additionally, it's crucial to consider common care factors, such as inflation, living costs, and possible changes in investment returns over time.
When using the FIRE Withdrawal Rate, it's essential to keep in mind that this is a general strategy and may need to be adjusted according to individual circumstances, such as risk tolerance, time horizon until retirement, and other personal financial factors.
