Calculate your Financial Independence Retire Early (FIRE) goal. Enter your savings, income, expenses, investment return, and withdrawal rate to estimate your FIRE number and the time needed to reach financial independence.
A FIRE calculator is a financial planning tool that estimates how much money you need to achieve Financial Independence Retire Early (FIRE). It helps calculate your target retirement number, savings timeline, and the investment growth required to become financially independent.
The FIRE approach focuses on building enough invested assets to cover your future living expenses without depending on employment income.
FIRE stands for Financial Independence Retire Early. The goal is to accumulate enough wealth that your investments can support your lifestyle.
| Term | Meaning |
|---|---|
| Financial Independence | Having enough assets or investments to cover your expenses. |
| Retire Early | Leaving traditional employment earlier than the standard retirement age. |
| FIRE Number | The amount of money needed to support your retirement lifestyle. |
A FIRE number is commonly calculated using annual expenses and a withdrawal rate. Many FIRE investors use the 4% rule as a guideline.
| Formula | Description |
|---|---|
| FIRE Number = Annual Expenses ÷ Withdrawal Rate | Estimates the investment portfolio needed for financial independence. |
| Example: $40,000 ÷ 4% | Creates a target portfolio of approximately $1,000,000. |
The 4% rule suggests that a retiree may withdraw approximately 4% of their investment portfolio annually while maintaining a long-term retirement strategy.
| Annual Expenses | Estimated FIRE Number |
|---|---|
| $30,000 | $750,000 |
| $50,000 | $1,250,000 |
| $80,000 | $2,000,000 |
| FIRE Type | Description |
|---|---|
| Lean FIRE | Focuses on achieving financial independence with lower expenses and a simpler lifestyle. |
| Regular FIRE | Aims for standard financial independence with typical retirement spending. |
| Fat FIRE | Targets a larger portfolio to support a higher-spending lifestyle. |
| Coast FIRE | Reaches a point where existing investments can grow without additional contributions. |
Your savings rate is one of the biggest factors affecting how quickly you can reach financial independence. A higher savings rate generally means more money is invested each year.
| Savings Rate | General Impact |
|---|---|
| 10% | Longer path toward traditional retirement. |
| 30% | May significantly shorten retirement timeline. |
| 50% | Can accelerate financial independence substantially. |
| 70%+ | May allow very early retirement for some individuals. |
| Factor | Impact |
|---|---|
| Income | Higher income can increase investment capacity. |
| Expenses | Lower expenses reduce the FIRE target amount. |
| Savings Rate | Determines how much money is invested each year. |
| Investment Returns | Affects how quickly investments grow. |
| Time | Allows compound growth to increase wealth. |
A person with annual expenses of $50,000 may estimate their FIRE target using the 4% rule.
