Playing With Fire Retirement Calculator

The FIRE Retirement Calculator is a powerful online tool designed to help you estimate when you can achieve Financial Independence, Retire Early (FIRE). By inputting your personal financial details—such as age, savings, investment returns, and expenses—it projects your potential retirement date, required savings (your FIRE number), and whether you’re on track for early retirement.

The tool is based on the classic 4% withdrawal rule, widely used in the FIRE community to calculate sustainable retirement income without running out of money.

How the FIRE Retirement Calculator Works

This calculator uses a combination of:

• Compound interest growth for your current investments and annual savings.
• The 4% Rule (or your chosen withdrawal rate) to determine your target portfolio size.
• A progress tracker to show if you’re financially ready for retirement.

Example Calculation

Let’s say:

• Current Age: 30
• Retirement Age: 50
• Current Portfolio: $100,000
• Annual Savings: $20,000
• Expected Return: 6%
• Annual Retirement Expenses: $40,000
• Withdrawal Rate: 4%

The calculator would estimate:

• Years Until Retirement: 20 years
• Portfolio at Retirement: ~$1,066,000
• FIRE Number: $1,000,000
• Surplus: ~$66,000
• Safe to Retire? YES!
